True
For SSDs, remember that independent reviews are not trustworthy if the manufacturer decides to change the internal components without telling anyone or rebranding the SSD.
At that point all you can really do is buy from trustworthy brands like Samsung & Corsair
@@PashaGamingYT Samsung did the same

Poor choice of words when saying "trustworthy" because you're implying those reviewers have something to do with the fraudulent advertisements from the manufacturers. A better word would be "accurate" due to the review being tied to *when* they got the product.
@@PashaGamingYT corsair does this kind of thing too, just recently they removed the secondary timings from their website for some ram kits, and they when caught they put them back in.

1 thing you missed: when people just say “it is an i5” instead of the model or generation.
one time i was with a teacher working on someone else's laptop for a project and the laptop had 8th gen i5 i think, or something like that and it was pretty funny hearing her say "this is a fast computer, wow *looks at sticker* it has Intel core too, wow"

Best Buy worker: "...um, uh...yeah it does. But you should get this one (points at different laptop) because this one has uh...(trying to remember) 4K."
And probably that 4K laptop had a 5400rpm HDD, which will make the laptop very slow. I bought a cheap HP laptop 3 years ago, and despite having specs that were decent (at least decent for my needs), it had a slow 5400rpm HDD. Thankfully I upgraded it to an SSD, and put the HDD in the Optical Drive bay to use it for extra storage.
@@DacLMK In laptops is really a hassle, those 5400's don't perform apropiatelly at all, but for my desktop I only use high speed spinnies (Toshiba P300 storage, Toshiba X300 performance), and I cannot see any measurable performance degradation in comparison to others SSDs, only problem would be fragmentation but with Diskeeper that's also a thing of the past.
I have a hard time checking if the “SSD” on a laptop is eMMC, NVME or just SATA.
There are some budget laptops that can come with 256GB “SSD” storage, but hell if I know if I can swap out the drive or no without opening it up and voiding warranty.
@@Mageman17 If it's not soldered memory (cough Apple cough), of course, and upgrades don't void the warranty, it should only be void if the brand can prove that you broke the machine intentionally or by mishandling it.
As for how to know the kind of memory, sometimes the manufacturers website has the info, if not, you could try and find a review with some sort of teardown and if that also doesn't work, you could try and search for replacement part numbers and watch there the kind of storage that it uses, this last method is the least ideal as this lists are not always perfect, to say the least, but as a last resort...
@@Mageman17 SATA is a connector (or communication protocol), while emmc and nvme are actual storage technologies.

TIP: Just because a psu is rated 80+ bronze/gold/yada yada, it doesnt mean its good only because of that. Best metric is cybenetics
what is it
I really hate this. Gamemax is a really common brand in my country and their power supplies are noisy and unreliable, but you can find them with bronze certification for much cheaper than a white EVGA PSU, for example.
80+ ratings are only a indicator of how efficient a psu is at certain amounts of load, while a 80+ certification is not a indicator that the psu is reliable, a psu without 80+ certification almost always is unriliable
legit question, what is cybenetics, and do brands put it on the specsheet? i never seen that

I know Linus goes over ranks for RAM, but maybe even a Turbo Nerd edition on why RAM timings are more important than the frequency? I know Linus says it all the time but never really did a deep dive the way he explained ranks.
Why is an SSD faster than a HDD if both run at the same MB/s theoretical
Its because of seek time (get this > is this right > its corrupt > here it is again) 4x 16 = 64 like wise 4x 18 = 72
And so with a different amount of operations that can be done inside a set frequency means you get different performance
Truck has infinite space and no loading or unloading time, but takes X time for House A to B before it can do C to D before it can do E to F
I want 1000 things that total 1GB vs 1 thing that is 1GB
Explained it as best i can
ram timing are not more important than frequency. frequency is also not more important than timings. its more a matter of you need to know both to get an accurate idea of performance.
both are directly linked. neither of them is more important. higher frequency usually means higher timings. that's what you saw when we went from ddr3 to ddr4. essentially both frequency and latency doubled which means the performance is same. ddr3 1333 cl9 vs ddr4 2666 cl18 for example. ofc now with ddr4 being around for so long the tech evolved and we see higher frequencies at not so shitty timings which means something like ddr4 3200 mhz cl 14 is now quite faster than ddr3 but in the beginning that wasn't necessarily the case. however saying one of them is more important is just wrong. you have to look at both to get an understanding of the actual performance.
cas latency stands for column access strobe latency and the number means how many clock cycles are passing when your cpu requests data from a memory modules particular column and the time in which it responds to it with the available data.
so with that in mind you can understand why neither of them matter more than the other. higher frequency ram means that the clock cycles are faster or that you have more cycles in the same time than with lower frequency ram however higher latency means that it will take more cycles before the ram delivers the requested data. this is why ddr3 1333 cl9 and ddr4 2666 cl18 will perform really the same. the ddr4 will perform 2x the cycles in the same time however the requested data will also take 2 times as long to come back so you won literally nothing. ofc ddr4 had other improvements over ddr3 that aren't related to speed but that aside the two examples here would perform like one another.
RAM timings are always given in clock ticks so yes, both matter. I.e. you divide the CAS latency by the clock speed to give the true latency.
The point is rather that an increase in clock speed is unlikely to be worth much if it's accompanied by a similar increase in the timings, and that faster RAM with really bad timings may end up being slower in practice.
@@Matt__B agreed buddy. Both memory frequency and timings matter but today it doesn't seem like they matter nearly as much as they did with DDR1.
The lower the latency the faster the memory can be accessed at any given time which is very useful for benchmarking apps as well as games.
This laptop (i7 10750h hexacore, 2 x 8GB DDR4 - 3200 runs at 1463MHz CL20-20-20-47-67 @ 1.2v) but I have not even been into the BIOS as I doubt a Medion laptop will allow me to change the memory timings.
i'm most frustrated with how portable speakers are marketed. Usually they have a power rating and a frequency span. But. A tiny thing that has no bass is often spec'ed as 20 hz to 20 khz, while an actual good speaker says 60 to 14k... and the power rating, which is usually just an electrical power its amplifier may be able to deliver into a resistive load... pfff, that has no relation to how loud and how clean the sound will be, and it's the sound that eventually matters.
Why you have to check the frequency response graph, will give you a very accurate idea of what it actually sounds like, though not all manufacturers provide them, and you also need to know how to read them
Over the years there had been many attempts to certify speakers to represent how good they are (remember how THX was important?) , in the end most of them do not mean much since different people listening from the same speaker would tell you different things. Especially the higher end it goes. Truth is there's no 1 unit alone that gives the 20-20k range nicely, there is a reason why tweeters and woofers exist, and where they crossover and how the frequency is distributed create different sound that appeal to different people.
Easiest example is Bose, some love it , some avoid it like a plague.
And yes , do try the speakers to see if you like it instead of someone telling you "its good" , audio equipment review is almost like fine wine review , its a matter of taste.
With the "electrical power its amplifier may be able to deliver into a resistive load... pfff, that has no relation to how loud and how clean the sound will be" do you mean that that suggests that a lot of power is lost on heat or?
@@syralessthanthree with any oscillating system (in this case, the speaker diaphragm moving to vibrate air) power delivery is complicated. You will always have some portion of the power that gets reflected back to the power source, instead of transferred to your load (in this case, converted into sound).
The frequencies at which very little power is reflected are called 'resonances' and these are affected mostly by the size of the speaker cavity. Larger speakers (woofers) resonate better with larger wavelength (lower frequency) oscillations, so they couple better with deep sounds. However, the heavy diaphragms are difficult to oscillate quickly, so trying to generate high pitch sound from these devices is inefficient.
On the other hand, a smaller speaker with a stiffer diaphragm will give you much more efficient coupling with high pitch sounds.
I think OP is referring to the fact that, just because the amp can deliver a certain amount of power, not all of it couples into sound gen effectively. As you correctly suggested, if the power does not couple well, it gets wasted as heat and sound quality deteriorates.
@@desmondlau4632 looking how covid is going, i don't think the saying "avoid it like a plague" really means anything now a days.

Taking your car analogy for processor clock speeds, it's more like choosing the car based on the engine RPM, rather than top speed
And top speed isn't a good indicator of performance either; it doesn't really showcase how long it takes to get there.

Strange how things change. Once upon a long a go, a CPU's clock speed was the most significant measure of the speed of a processor and resulting system...then came multi-cores and as better manufacturing techniques as mentioned in the video and its significance became arbitrary (not strictly true, but useless as a direct measure of comparison).
Well, the freq was found to be an absolute dead-end loooong before Pentium 4 could overclock to 5GHz+, and with all the cool shit you could do with a computer, stopping at freq and a single core per package would leave it all a dream.
Like, try building a massive supercomputer with max-clocked Pentium 4's (a clock which doesn't require liquid nitrogen as the cooler). Google's or Facebook's cooling systems wouldn't be remotely enough, and astronomically unreasonable money would be wasted just to run the CPU's at 100% for 1d.
It was probably easier to increase clock speed than increase IPC. When they couldn't push it any further they had nowhere else to go.
@@morosis82 to be fair though, IPC was pushed so much to the limit that increasing it even further at the time was deemed to be straight up impossible for a single core cpu.
Research focused on two paths, dual core cpus and increasing the clock to extreme levels but both had huge issues:
Increasing clock inherently required to leave a bit of the IPC on the table (as it needed very long pipelines) and compensating for that while dealing with the increased power and thermal requirements would be extremely difficult.
Dual core cpus on the other hand had huge issues with resource sharing and interlock, some of which were deemed basically impossible to solve.
Resource sharing between cores also translated into an inherent penality on performance and thus, even if they worked, it wasn't that obvious that increasing the number of cores would lead to an increase in overall performance.
They quite looked like dead ends.
Therefore, although the clock increase path was hard and had many disadvantages, at least it was the more feasible and it was also the (financially) safer option any way you look at it, so it was the path taken with the pentium 4.
Of course, with time, we found out that not only dual-cores are really feasible but, because the performance penalities can be worked around for the most part, they are way way better than single core cpus.
Therefore we can easily say that, in hindsight, the path taken with the pentium 4 was the wrong one and, indeed, the real dead end between the 2 but, at the time, things didn't quite look this way.
I have a SLIGHT disagreement with the CPU argument. yes, it's true that not all CPUs are made the same anymore, but hard numbers are STILL relevant within 2-3 generations. (for example, a 1st gen Ryzen (1XXX) can still go toe to toe with a 3rd gen Ryzen (3XXX) ) Is it perfect? No, but it certainly has some merit still
@@saikapirt9783 Su~re, but the Ryzen 3 1000 tech is hardly even comparable to anything before year 2010.
Hell, CPU's and by extension GPU's are reaching their copper limits, so they've been looking into other materials for at least 6y by now.
Suggestion. A whole video on mega, giga, terabytes vs. mebi, gibi, tebibytes, where you see commonly each, and how to interpret what you're seeing. Wholly crap are those two mixed up all over the place, both intentionally and unintentionally, and it causes a huge amount of confusion.
Edit: Adding on to abbreviation confusions, an explanation of the difference between MBps and Mbps. Most people don't know that 8 small b's = 1 big B. I've always thought that ISPs and other industries marketing data transfer technology take advantage of consumers knowing everything in Bytes to confuse the issue and make their _bit_ per second speeds sound 8x faster than they are. This is further confused when you add mebi and mega prefixes into the mix.
They already did a TQ on this a while while back

It's it's definitely a sham, because they basically redefined terms to make it work.
...I hate that I'm just learning about this in 2021.
8 bits to 1 byte
8 gigabit = 1 gigabyte
When talking about windows they use MB, GB, TB and so on but they are mibi by law cus of legal BS decades ago
But that is because they are using true size before the legal BS that had the size changed
So for windows 1GB is 1024MB
Same on linux would be 1GB is 1000MB because of the legal BS
Its really not hard
Bit = 8
Byte = 1
Mibi = +24 to it (gibibyte 1024 megabytes)
Then to internet MB/s is megabyte’s per second
mbps is megabits per second
80 mbps = 10MB/s (so some would say its MBps and assume people are smart enough to look at the capitals vs lower case)
GB/s = 8 gbps
Gigabit internet = 125MB/s
All of it is bit vs byte with 8 bits being 1 byte and mibi is +24 seeing as that is how computers count 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 and legal BS spawned the mibi into existence
@@InfernosReaper this! this to me is the worst part about it. Like, by now i'm used to the MB vs Mb thing, the worst part for me is how IEC redefined Kilo-, Mega- etc to refer to decimal instead of binary...it's ALWAYS been binary in computers, now all of a sudden the correct term is MiB?

I4 litre motorcycles Aka superbikes are actually way more faster than almost all but some hypercars or modded cars. A 200 bhp I4 litre motorcycle will outperform a 600 to 700 bhp V8 car, because the motorcycle weighs very less compared to the car.

Otherwise you're absolutely correct. ^^
Thanks, I needed to know the Random IOPS rather than the sequential speed, but I'm sure when you're transferring files to another NVME, that matters until it hits the buffer limit on the cache
IOPS is sure one of the critical SSD performance aspects, but it's useless if you don't know the other factors such as latency (how much time does it take to reach a block), block size (the smallest space unit that can be edited/deleted), RAID configuration, Read/Write percentage and Sequential/Random percentage.
Unfortunately, vendors rarely if ever reveal the rest of their benchmark values and results. So IOPS is not that reliable in this case.

How are people working/browsing using super bright HDR laptops? Doesn't that hurt your eyes? The 4K OLED HDR panel on my P1 G3 is I think 500 nits, and I almost never use it at full brightness because it's just to bright.
Maybe it's because I tend to be in a darkened or at least dimmed room? Maybe my eyes are just ❄️❄️? I genuinely want to know.
Those 500 nits come handy when the sun shines from just the wrong angle and for some reason you can't do anything about it.
For example most of the time I use my 350cd/m2 display at 75% ro less, usually 50%. But when the sun shines on my white wall, then sometimes even full brightness can be just barely adequate. But that's indoor. But you can take your laptop outside too, which requires much brighter display to be seen in bright sunny days.
It's both personal preference and depends on the room lighting. I have a 400 nit monitor, and it's perfect during the day. In the night I still can use it at 100% brightness just fine, but nobody else who tried can.
the peak brightness is the important thing. For example, a picture of sun is just a chunk of color on none-hdr display. However, hdr screen can show it's shiny-ness because of its brightness. Also, hdr is not only about the brightness, but also the range. It displays high brightness areas and low brightness areas at thesame time with high fidelity, it's simply not possible on none-hdr mobitors
By the way, if you wonder how bright the actual sun is it's somewhere around and equivalence of 1 billion nits. So theres still a long way to go to actually see the sun in movies to be just like the actual sun...
They don't lol, they dim the displays just like you do. Both HDR and SDR content can be dimmed. HDR loses some of the point obviously, but it's better than being blinded.
Riley keeps giving me the technobabble my computer illiterate friend likes as background noise to sleep where I rant to them.
*I love the tech news and I love Riley
Lol apples to oranges, good one guys XD
Edit: So yeah, you covered the stuff I hate seeing already on products, but one thing i hate that usually isn't included, more with laptops than anything else are specs that AREN'T included, you buy a new laptop, thinking about future upgradability, but you usually have to go to the manufacturers website and read through a bunch of fine print just to find out if it has a second RAM slot, or an extra M.2 slot or if everything's just soldered onto the board, and even then sometimes that information isn't included so you have to go somewhere like LTT or another reviewer so you can find a teardown of a laptop, all so you can find out if its what you're actually looking for.
also annoying when there are so many different variants of a type of laptop (eg nitro 5) and a bunch of them are different enough where some have different compatible parts than others or don’t have certain upgradability slots
I prefer oranges
I don't know about specs that are unimportant, but one spec that's pretty important that's almost never listed is whether the RAM is configured in single or dual channel. Single channel RAM, especially for integrated graphics, absolutely destroys performance.
Why does it destroys the performance? I would like to know if I should add another ram stick :)
@@marius0448 You always want dual channel memory. It's like tying one arm behind your back without it. You _can_ do the same things but it'll be slower.
That's just a general way to look at it. And unfortunately you can't just add a second stick of ram. So ask someone who knows to find the right memory for you and make sure it's set up correctly.
@@flameshana9 yeah,but i was curios why is it faster? I ve seen this many times that dual is faster.
@@marius0448 Running RAM in single channel essentially halves the speed of your RAM. So one 3200Mhz 8gb module in single channel mode will have half the speed as two 3200Mhz 4gb modules in dual channel mode. They’re still technically running at the same clock speed, but the bandwidth between the RAM and CPU is doubled in dual channel mode, so twice as much data can be pushed through in the same time interval. When you use integrated graphics, your CPU and GPU both share system memory, so a dual channel RAM configuration will dramatically increase performance in games.
@@HPerrin Thanks man,u explained very well!! So with dual channel the cpu and gpu can get from 2 sources at the same time,when in single they can get only from one source at one time :)
Recently noticed the SD Association recommends their "SD Memory Card Formatter" Tool for formatting SD and SDXC Cards because the formatting of the operating system is "not optimized for sd cards" and the performance could be lower.
The difference betweet the formatting tool and the windows bultin would be interesting.

Don't forget video card memory. I have some fun memories from my childhood with my friends claiming their GeForce 4 MX being "faster" than my GeForce 3 Ti because both cards had 128 MB on board and 4 is a bigger number than 3 :P
A Tech quickie on different color gamuts would be nice. I have no clue what DCPI-3, Adobe, or SRGB color spaces mean or how they differ. What would a typical consumer be looking for?
We need this comment to be a video, seriously
About monitors, another thing people don't tell is AV Lag, which is the syncronization between the image and audio(specially if you are running audio through a Realtek(realteks boast at minimum 45ms of audio lag)). You can try and run a Realtek or similar audio device(USB headphones, etc) at 512 samples(20ms), but you need to run it in ASIO or WDM mode, as MME(which supports all audio card effects) doesn't run so fast.
High AV Lag makes it hard to play music games.

Thanks for the HDR part of the video. I was going to buy a "HDR" monitor. Now I'll research again for better monitor.
HDMI cables which only go up to 30 fps at 4k. The version matters a lot.
Cable is cable.
@@hubertnnn Only if they're the same HDMI version. In the current age you should _never_ buy an HDMI cable below version 2.0 or you'll end up with 30 fps and no HDR support.
@@hubertnnn not as much as it used to be. To many damn #.x cables now. Oh is it USB 3, oh but it's not 3.2. Oh it's HDMI 2? Good, oh but it's not 2.1 and doesn't support (hdcp/earc/4k 60/some other random ass thing you won't realize is missing until after the return period ends)
As I said, cable is cable.
Cables don't support features, all they do is transfer data, and the only things a cable might differ form one to the other is:
- how much current it can transfer (mostly irrelevant for data transferring cables)
- how different length of each wire is (and thus how synchronized signals on each wire are)
- how well its shielded (an thus, how much noise it will catch from outside)
- what is its resistance
A high quality cable will be able to handle many generations of standard in the future. (unless new standard added extra pins and wires).
But the truth is that most cables are not high quality and barely even fit requirements of current standards.
Cut a modern cable and you will be amazed how its possible that its even working (if you have any experience in electronics).
@@hubertnnn Google the differences between HDMI 1.4 and 2.1 and then edit your comment. There's no such thing as "a high quality variant can support many future versions" for a hardware standard.
I just wanna add it here, common traps nowadays in Laptop Entry Market is putting the words "Fast Intel Quad Core" in ads only to find out it's just a Celeron if you dig deeper in research... Which is a trap for those who are new and with tight budget... In short, Google and CZcams is your friend...
A good analogy for how cpu power works is a car:
GHZ = engine rotation speed
Usage percentage = How much of it's horse power is demanded
Cores = Count if pistons in the engine
Hyperthreading = Doubling of pistons
Cache size = How many Litres does the engine hold
Boost clock = turbocharger
IPC = gearing that the car can use
Eventual speed is mostly determined by ipc+ghz if it is not at its limit because of to few cores (not enough horse power)
Speed is nowadays determined mostly by how bad the application is written = how much car weights thanks to the all unnecessary crap incorporated in its shitty design...
I own a hosting service and for our clients the clock speed is sometimes important, if it's a VPS. As some of them run a FiveM Server and it depends on a high clock speed
The most frustrating is compare smartphone camera specs. I basically hope to have a CZcams video of some one comparing the two devices that I'm interested to
who cares? unless your price range is $100-$200 any phone camera is adequate to take photos of food that will have filters applied to them and uploaded in 640x480 to instagram. if youre actually interested in taking proper photos, you already have a camera.
For M.2 SSDs, I use the rated read/write speeds to make sure that the SSDs is NVME vs. SATA (as for some prebuilts/laptops and even some M.2 SSD listings, they don't always make it clear).
Just because its faster than regular sata doesn't mean its nvme. It could be ahci
That's actually a really good tip.
@@AltonV are there SATA M.2 SSDs that aren't using AHCI? In any case, the max speeds possible are around 550 to 600 MB/s. So, faster than that and you are dealing with NVME.
@@penguinguyx I have an m.2 ssd that is NOT nvme and are rated for 2,150MB/s read and 1,200MB/s write

This video is gold! On the subject of audio, people should ignore the frequency range of a speaker or headphone. It doesn't have a standard measurement scheme and it says nothing about sound quality.
Can you guys do more of these? Perhaps a more in-depth look into this?
4:12 Monitor Response Time!!! All those monitors sporting a "1ms response time", but that measurement doesn't mean anything anymore, it could be 1ms at a ridiculous overdrive setting with 80% overshoot or something
When they say a laptop screen supports 1080p like bitch every other laptop screen does

@@rpgfeatures793 11ms is very high, usually people can't tell apart monitors when it's 4ms not 11ms
For most of these, it feels like it's a matter of "all else being equal, a higher number here is better - but in actuality all else is rarely equal"
A big thing about computer specifications is that so many of them are context dependent. A useful "sequel" to this video would be to propose spec minimums for different usage scenarios. Kind of like the the gaming video LTT did headlining "El Cheapo," show us recommended specc'd PCs including "office PC" and "gaming" "video editing" "software development" "3d modeling" "CAD" and "photo editing"
That's pretty easy. For casual users single thread performance is what matters and then just throw in the minimum of 8gb of ram. For power users you want 16gb of ram. Then core count/multi thread performance would be the numbers you want to be bigger. For pro's it depends on your job, so you wouldn't ask for generic advice. And there's tons of videos already on gpu performance.
But yeah. A few recommendations for builds/premades would be handy for newbies.
Another one that doesn't work out properly in actual usage, I've got a 45W intel i5 Skylake laptop. It will drop down to ~2W in light usage situations, the same as the 15W laptop CPUs, only my 45W laptop has a *much* larger battery, so before the battery got old and lost some of it's capacity I regularly saw 8+ hours battery life out of a 5 lbs, mid range gaming laptop when using it for light work.
The 15W laptops have much smaller batteries, their power draw is lower at peak but virtually identical at light usage.
I think the clock speed info about CPU's also now applies to GPUs. Like how current Ampere GPU's might clock slower than previous generations but still preform as good or better.
Now? It always has to my knowledge
@@commanderoof4578 I admit I did not know if that was the case with the older generations. Good to know though and even more of a thing to know when buying a part.
@@JKirkInTexas it can be the same in the same generation as well so a 1030 vs a 1080 ti both at 2GHz using the same amount of Cuda Cores will give different results despite being the same because of transistor counts per core for different DIE designs and such
IPC is a turd 4GHz is not 4GHz CPU to CPU or GPU to GPU unless its the same model or same die with more or less of its cores enabled or disabled

I am always bugged by the GPU in the spec sheet whenever i shop for a laptop. They just erase the wattage almost all the time and i need to go out of my way to look for that particular information myself somewhere else.

worker: It's the latest version.
Me: Understandable....
Agreed. Laptop GPU wattage is a mess.
Frustrated about not even being shown the exact models of those components by the PC/laptop/whatever manufacturer. Only some do, so in essence they don't even give us something to be frustrated with. Frustrating.
most offensive to me is 'core i7' because that literally means nothing. there was wven a 7w i7 at one point, the Y series, and most common is the U series, what you want in a performance laptop is the H, and thats just the mobile side
@@bradhaines3142 True, my i7 8565U is just 20% faster per core than my desktop i3 540 (1st gen), at least when reencoding video on FFMPEG.
For me now that a monitor no longer needs to have the G-Sync module to be certified can be annoying especially when premium high priced units can now claim this
2:54 Tests, that are as helpful as a 3rd and blind eye under your heel. As SSD manufacturers are known to replace ALL components with even different specs ones, at random, without updating the device name, internal number-name-thingy (I forgot what it is called in English), or even revision number.
You can buy seemingly identical products a few months apart and get very different devices. And often the parts later sourced are cheaper and worse in performance and life. So, best is to get it while new enough that still reviews are trickling in. As it seems the product is still in write off phase before the bait and switch kicks in, and they start to sell you crap which only has the box is common with the devices you have read tets about.
Comparing clock speeds was a valid point at least to the point dual core CPUs entered the market.
Long before that. Of course CPU makers are testing shit out before they start producing cuz if your product is dead or pretty much, you'll have returns the instant you sold it, totally wasting all the money in production and what else.
So, the freq was a dead-end long before multi-core happened.

CPU ghz is right. I have g3460 which is 3.5 ghz the ryzen 5 2600 will be faster despite having 3.4 ghz.
My 9750H could be listed as either 2.6gHz, 4.0gHz, 4.2gHz, or 4.5gHz depending on which spec you want to use. None of these are a good metric, as 4.5 and 4.2 are temporary turbo states for a single thread (different time and thermal limits), 4.0 is only for all 6 cores when under a high load and thermally safe, and 2.6 is roughly the base clock it hovers around when totally idle.

Looking at the processor name is often more useful, the only time you can use the clock speed is when you have CPUs from the same manufacturer from the same architecture. For example, my old Pentium T4300 is 2.1GHz but my i7-8560U is 1.8GHz but it way faster.
well its normal a more powerful cpu and gpu normally has more cores! the real reason the gpus for the ps5 and xbox seres x that i say are very expensive despite the clock frezesy is because of HOW MANY CORES! the ps5 and xbox seres x have over 30+ cores in there gpus by the way! also its 1.3-1.5 GHz for each of those 30+ cores all add up! cpu/gpu tolatal speed is calated by this eqasion i put here! this is basically base core clock speed X per core on the gpu or cpu die = total prosseing clock speed! for example a 3.5 GHz i5 processor that has four cores witch all put together would go up to like 14 GHZ max! meanwhile a f*****ken AMD ryzen zen 2 core riper that clocks at 1.3 GHz bas core spped but due to having over F*** 30 cores this would make the cpus total clock speed then would go over like i don't know like 70 GHz at the least! but only thats if for the most part if all the cores where used all at once! but however that's only if it doesn't just make so much radiation and cooks itself in the process if not properly cooled!
@@ashtiboy I thought cpu and gpu cores were very different. As in GPUs have hundreds or even thousands of cores.
@@flameshana9 actaly a gpu is a cpu that has its own dedicated ram memory for video/extra memory cache data storage! a gpu basically is just a cpu with a ram memory card attached to it so it doesn't have to wait on the memory storage drive/cpu! also back in the old days cpus had to do both graphics and regular processing before we made gpus a thing!

Sheesh I always thought the mentioned specs were really important whenever checking out any product
Companies these days downgrade specs after big marketing
Dunno if it's sarcastic or if you are for real, but just in case:
It's not that it is not important, but it is "important to a certain extent".
To take the example in the video, all of them are important if you know how to read them, the Speed indicated is still a real speed you get and if you , say for example, need the SSD for quick small files transfert, it will be important to know this speed.
But you have to always take all those information in CONTEXT, which is something the companies that sell are happy to forget.
Kinda like they will happily offer you the possibility to pay in multiple (monthly, bi-monthly...) part, but will tell you the % of interest at the last second :^)
In short: Those information are still valuable if you know how to read them and in which context to put them, but yeah for the vast majority of the people they can just forget it (hence the video).
