- The new Ryzen 5 8400F might sound like a tempting choice for a sub $200 / £200 processor, but there are other options that should be considered first.
Today we're talking about this "budget" 6 core, 12 thread AM5 chip.
Thanks for watching :) - Věda a technologie
r5 8400f vs i5 8400f lets goo
Coming soon haha
😅
it will crush it.
@@subbookkeeper no clue
There's no i5 8400F, I think you meant i5 8400. There is an i5 9400F though.
how dare you wont upload for a week. What am I gonna watch when Im eating
The 7500F is better because max clock is 5.0 Ghz vs 4.7 of the 8400F and doubled the cache, more PCI-E lanes.
Yeah basically sums it up
@@RandomGaminginHD Moreover I think the 7500F from AliExpress is cheaper???
Well, 8400F has a much higher base clock for the same TDP, and it natively supports USB 4 ports.
@@bills6093 higher base clock means nothing, and the 7500F have faster cores than the 8400F because having more cache
how the 8400F supports natively USB4? It should be Motherboard dependent
8400f has HALF the cache of 7500f, they should have been selling it for like $130 or something, it should be cheaper than 8500g, in games it's often not much better than 12400f
this is why cache is so important
Naa. We're talking here about framerates above 100fps. This is what we call "nitpicking" at this level.
Oh nobody here knows about that? The reason why the Device Manager shows a Microsoft Basic Display Adapter with the 8400f and detects an Image is: The iGPU is disabled, but the new NPU Part of the 8000 Series is still enabled. That might be why!
When trying to look up info on it some sites say the NPU is disabled on the 8400F (but not the 8700F) but the info varies so not really clear if it's true or not. Would be interesting to boot up this cpu in linux as well to see if that reveals anything different about what device is enabled here.
This might be a BIOS issue. I just got an MSI PRO B650-S, and the BIOS version required for the 8400F is more recent than the one supporting the 8500G (3 months apart). The one for the F version was released about 2 weeks ago.
the 7500F can still be bought on aliexpress for as little as $130 USD, if you can wait a few weeks for international shipping then there really is no good reason to get a 8400F, 7600 or 7600X over the 7500F for a gaming pc.
Price is everything. This has to be dirt cheap to be worthwhile.
Yeah, the 8400F is a strange product with a strange price, like over here in germany you can currently get the 8500G for less money then the 8400F, it really doesn't make any sense. The 8500G can currently be had for 154 Euros while the 8400F costs 160 Euros and even the 7500F tray CPUs are cheaper at 159 Euros.
That makes sense the 8400f is a 8600g cut down with six full cores. A 8500g has a mix of full zen 4 and zen4c cores.
This is literally a follower of such budget stumps as the Ryzen 3500 and 4500, the weakest 6 core processor in the current line.
The sane price for this stuff is 100-120€, for competing with i3 12/13/14100f.
Here the 8500G is R$ 400($ 74) cheaper.
I love this "vlog like" videos
Regarding the memory apu’s are typically paired with beefier memory controllers so it makes sense that it wouldn’t struggle as much at higher frequencies
"typically" AMD apus have historically struggled with faster memory lol, there is nothing typical about this, if faster memory works that's usually a fluke.
@@arcticowl1091 Are you sure I recall a couple of reviewers saying this. And the apu reviews I came across trying to find the exact video all utilize 4000 mts ram instead of the more common 3600. And this video seemed to back up that statement.
If you have any reviews or videos saying otherwise I’d love to look and change my comment accordingly :)
@@sjargo11 4000Mhz is extremely rare because it's usually twice as expensive for maybe 5+- more fps. That is not worth it considering the higher end motherboard you'd need to make sure it plays nice and hope your cpu can actually run the BCLK at the right speed. Mismatching the BCLK and memory clocks is a good recipe for causing hang ups.
@@arcticowl1091 I agree it’s generally a waste of money though I don’t see how that’s relevant to my previous comment. Also I’m not familiar with the term BCLK.
I think I got the statement from either hardware unboxed or iceberg tech the latter of which I looked at the reviews of some apu’s where 4000 mts ram was used. Which seemingly agreed with my original statement, I’ll definitely look at more reviews after this, but until that I’m sticking to my original comment/point. If you have some examples of creators or reviewers where this is brought up I’ll be happy to watch them and again change my comment accordingly.
@@sjargo11 BCLK is the clock of the interconnect fabric, aka the infinity fabric. if it doesn't run in sync with your memory, it will cause hang ups because one has to wait for the other to get in sync.
The 8400F isn't worth buying considering the existence the 7500F
Yep pretty much
Price could drop and then it will be your best friend 😁
8400F is monolithic and consumes much less power in idle than 7600 or 7500F, because my PC is 80% idle and light browsing i'll choose 8400F and pair it with RTX 4060 more than enough, it'll make 4060 run games at 99% all of the time anyway so..
@@a.bamatraf6054 not a trade off I would tell people to make losing so much performance for a little bit of idle power draw but if it works for you i guess it works
@@a.bamatraf6054 good viewpoint, very useful comment, thank you
Reminds me of when I bought the core 2 e8400.
I loved that old beast haha
my father still uses the c2d e8400
Be interested in the power draw and temps compared to the standard 7600/7500f.
Needs to be no more than $120 USD if it's slower than a 7500F.

@RandomGaminginHD Excellent review as always. Would you be able to review to Ryzen 7 8700F any time soon?
You're Back! Interesting that second detected GPU, does it happen on another motherboard? Thank you for another cool video :)
Yes it does!
I see that salt rock lamp just chilling on your table lol
I have two salt rock lamps myself nothing beats the warm glow these lamps put out.
Maybe this chip makes no sense in the AMD lineup,
but given its name "8400f", maybe AMD tries to target it against Intels i5 11400f-12400f-13400f-14400f...
Intel gives the 14400f an MSRP of around 200 Dollars. And it also has a turbo of 4.7Ghz, "only" 20MB of Intel Smart Cache as well ( not sure if that is Level 3, or Level 2 + 3) etc...
-> So, there is more than just its name which resembles the Core i5 x400f series.
These would be a good comparison too
The 7500f is awesome, got mine for 140 usd. upgraded to AM5 today, and what a beast. i did the curve optimizer, and auto OC on Ryzen master along with AMD Expo 6000MHz CL30 on a X670 MB. Cinebench score went up about 1200 points, and my CPU temps never went above 67 Celsius as compared to default which left the CPU at 83 Celsius.
I'm sure these are just bad APUs being sold as something else... I guess they don't want to price it so low it cuts sales of more profitable CPUs.
Much like the AM4 4500/5500 which where basically the APU without integrated GPU.
8600g with bad iGPUs .
I will tell you exactly what the 8400F is, it is an 8000 apu chip that failed the silicon lottery. Its also a mono die chip so it will usually do better with higher memory speeds just like the old 5700G.
Ryzen 5 7600 is $249 CAD and Ryzen 5 8400F is $239 in Canada. A whopping $10 difference.
I got my Ryzen 5 7500F for $167 CAD.
$72 cheaper. Insane value.
These cache crippled CPU's should be illegal D: But I mean not many gamers even know about cache or what it does :D But it's like tightening a rope around your leg so blood still flows but not well. Might seem ok for start but problems are gonna rise :D
The memory controller is stronger because its a cut down igpu model, iirc the igpu models had stronger memory controllers
Its Monolithic compared to Chipletbased full Desktop Ryzen CPUs. The G CPUs are basically mobile Chips. Its also the reason why there is no PCIe 5.0 and also why theyre cutdown lanewise.
Same goes for older Generations. 5000 Series non G CPUs are Chipletbased, the support for highspeed Memory ends with 4000 at best. Most Cases 3800. With a 5700G you can run 4200-4400 easily. Ive seen some 5700G even hit 4800MT/s. But for that youll need a top tier Mainboard, cuz of the integrity of the Memorytraces on the Mainboard (Same thing why SO-DIMM wont clock as high)
No it's not stronger, it just doesn't have the infinity cache to hold it back.
6000mhz ddr5 with low latency mode works perfectly with my 7500f, b650 mk and gskill 6000mhz ddr5 ram
It was worth the wait for the opening joke :D
Used PC with R5 4500 will sell faster than with R5 3600, because of "bigger number".
You can't fix some people.
It's a good bit more power efficient since it's a monolithic die, but if i'd want it for a server where those low idle power really are relevant, I'd go for a 8500g, which cost 5EUR more...
the r5 8500f is literary a r5 8600g apu without a igpu wich is laptop silicon so no infinity fabric so better ram stability
Except you’d be way better off running the ram at lower speeds for stability because other options have more L3 Cache.
@@user-bf5qh3ih4u i think it would be cool to tune it to run close to a laptop cpu
@@user-bf5qh3ih4u I think that it will depend on what kind of GPU you're using, and what resolution you're gaming at. If you're at 4K and using an Nvidia card, your point definitely stands. If I'm at 1080P with an AMD card, faster RAM and support for SAM might show better results. Please do correct me if I'm wrong. 💚
it's actually an 8500G, as it has 4 Zen 4c cores in place of the 4 standard Zen 4 cores. (edit: This is incorrect. it's all the same die.)
@@12100F Based on what info? Looking around all sources I've seen reference it having 6 standard zen 4 cores and no zen 4c cores.
8400f clocks memory higher, because it's monolithic. The same thing as with 5600G or 5500 chip. 8400f also is in newer node, so theoretically it should clock a bit higher. But idk, I'm surprised you say it's so hot. I also doubt that even with heavy oc and memory clocked as high as possible, it will be able to match cpu with 2x bigger cache.
It probably has thermal paste inside, maybe that's why it runs hotter
@@semyonzhigunov671 those ryzens have shitty IHS anyway.
just take a look at 8600g with dgpu bench.
it's around ryzen 5000 performance.
The 8400f is probably just an 8600g with a faulty iGPU, its definitely possible that AMD didnt even bother to disable the igpus by fusing off components on certain chips with igpus so faulty that it cant even run at all. Would probably new a few more 8400f samples to verify if this behavior is consistent with all chips.
perhaps it's more geared towards and office use scenario over a gaming use CPU.
I really hope one day a true performance x86 APU platform is released with CAMM GDDR flanking the socket from the top and left.
8400F supports SAM.
8400F has a single die, 7600 has 2 dies.
8400F has a configurable TDP of 45-65W, 7600 has 65W tdp.
8400F has "AMD Enhanced Virus Protection" (NX bit)
Both as a low-medium budget gaming PC pairing with an AMD card(using SAM), and as a low-cost solution for offices, schools, etc, this CPU *MIGHT* have merit. It might also benefit from easier OCing, but I'm guessing on that one. Also ultra SFX builds, I suppose, but that's probably a rare use case.
Well yeah, the APU is there physically in the chip, but it’s disabled, probably in the microcode. Just how most i3-i7 CPUs or the same gen work. If the die can’t run stably as i7, it gets some features disabled and turns into i5 or i3
Perhaps asking questions here is not really the place to do it, but this seems to be the perfect channel to ask it. Is a Ryzen 7 CPU better than a Ryzen 5. I am looking to build a basic gaming PC from scratch (mainly for simple games like Power Wash Simulator and Car Mechanic Simulator, etc. NO First person shooter at all and no online gaming at all. and was wondering (cost wise mainly,) if its worth going AM 7 route or sticking with the 5 series for now. I am not interested in Intel (unless I can be persuaded!.) Looking to spend about £700 all in. No case needed. Thank you.
Poor man building PC from new parts, such a pathetic comedy..
If I had to make an argument for it, then it would be its much lower power consumption at idle, like the R7 5700 vs. 5700X/5800.
I had both the 5700 and 5800 (non-X), and while the difference in their real-world performance was negligible for most practical purposes, the 5800 used over 30 W when idling, which was almost 3 times as much as what the 5700 did. My CPU is idle 90+% of the time, so the power savings could be significant. But for the same price, I would just go with an Intel i5-13490F or something.
It exists because chip that's used to make 8600G can have defects, but they either work at lower frequency or without GPU. So AMD had plenty of chips that they either needed to sell with defective portions disabled or if CPU core's were not stable at desired frequencies reduce the frequency.
I am getting confused with all these model numbers , at least intel keep it more simple .
Im thinking of going back too Ryzen , but they should be more clear . Great vid .
Whats the best allrounder for gaming and streaming ?
best allrounder should be an 8-core, that is either 5700x3d on am4 or 7700x3d on am5
Have you noticed any differences in power usage between the 7500F and 8400F? One big difference in my experience is power draw, especially at idle. The chiplet-based CPUs usually have a noticeable power draw overhead, even at idle, due to the communication between the dies, whereas the monolithic APUs can idle a lot lower due to them not having that communication and also being targeted at mobile. So if you were to build an SFF gaming PC, this could be a viable low-power option.
If you put your nvme drive in a slot controlled by the chipset you might be able to get the 8400f to run in x16 mode since it has 20 total lanes but only 16 usable so I assume since 16 are "usable" only 8 can go to the gpu and 4 to the ssd if its being controlled by the cpu instead of the chipset leaving only 4 lanes available hence the x8 mode for the gpu. it leaves room for a sound card, capture card etc if you're building on the tightest budget for am5 if you don't trust aliexpress and are pairing it with one of the budget x8 gpus like say a 7600/xt/4060 and i think the ti is x8 as well?
i believe this cpu may be getting tested improperly due to this limitation. i notice everyone running top end gpus to test this thing. not gonna be apples to apples if one cpu is stuck in x8 mode and the others aren't. i think either moving the ssd over to a chipset controlled slot will even these benchmarks out or this cpu will possibly prove to be basically the same as a 7500f, possibly better if they're all paired with an x8 gpu.
Will it perform better with a graphics card than a 8500g? Right now 8500g is $10 less. I am waiting for next gen Intel v Amd to build.
Yes, because this is crippled 8600g.
I am looking for your comparison video as there is a 7500f vs 8400f video by thegamrone here on yt where the 8400f keeps beating the 7500f, both at 1080 and 1440p. Only in Spiderman does the 7500f win at 1080 (but loses again at 1440) and in cyberpunk its reversed - 7500F loses at 1080, but wins at 1440p... Highly suspicious, although they said both cpus were at stock, so no pbo etc? (Even with a 360mm aio 😂).
If you overclock it with overclocked memory, you can get +20-30%
WOAH, That is not what i expected your face to look like, xd
pretty handsome ngl
Hey, check the benchmark figures. "Minimum frame rate" should be the absolute lowest recorded number in your test session and in rdr2 that figure is higher than the 0.1% low, so it's clearly wrong. Cheers
I was looking into using these for some budget builds in my shop, but for about £20-30 less than a 7600 why bother?
Exactly :)
And then there is 7500F...yeah, no.
The Ryzen 8400F and 8700F are interesting... It uses TSMCs 4nm tech vs 5nm with the Ryzen 7000-series. Also has native USB4 (40 Gbps). The 8700F still has the "AI" NPUs intact, while the 8400F does not. Probably hold off until the Ryzen 9000-series, though.
I would gather that the iGPU is disabled, however the hardware on your motherboard isn't and that is what Windows is detecting. Might be some function in the BIOS that is causing that.
There's no 7500F where I live, but you can get an 8500g at around 187 USD, while the 8400F is at 207 USD.
In any case, I'll probably get a prebuilt APU PC (way cheaper than building it myself) but I'm not sure if it's worth buying a PC with the 5700G and 16 gigs of RAM or the 8500g with 8 gigs of RAM (both are priced at around 425 USD)

Weirdly enough, where I live in the south east asia, what's elusive is the 7600 whereas the 7500f is what you'd find most
A week late.. I already bought it 😮
Is there a cpu or build you didn't review?
This cpu is a defused(without igpu)ryzen 5 8600g. I wasn't surprised when i saw it
As of my watchtime 3:47 this is basically the AM5 version of the 5700 vs 5700x
Agh, yeah. That 8400F reaching 87*C when not under a full load, tells me that the in-box cooler is inadequate.
But what if we pair it with a 4060 or a 7600 (both PCIe x8)? Does it limit the performance of the GPUs when compared to a 7500F or a 7600? Does it actually make any difference?
The lower cache capacity will still result in slightly less performance in most games, but it won't have an effect in games that are entirely GPU-limited or which don't benefit from more than 16MB cache
The restriction of PCIE lanes alone is the deal killer here. Why would they do this?
They crippled it. The cut-down L3 cache, clock speed, and PCIE lanes make the value proposition dodgy.
now if the 8400f was $75 then we might have a use case for this cpu. but who am i kidding, no one would release a new cpu for at that price.
The 8400F is actually closer to an 8500G than an 8600G, not there was much difference between those two in the first place. I'd just opt for one of the G models at this price point if you were skipping out on the 7400F or 7600 for some reason.
Was £144.99 over the weekend. Back to £165 now.
I think we have to wait for new BIOSes first, which will disable the iGPU completely.
Hey guys as a Ryzen 5 3600 regular user what is a now great upgrade for my Cpu? Or should i keep the 3600?
Depends on what you are doing.
5800x3d is the best (gaming) cpu on am4 but tbh i think it's better to go am5+7500f, +- the same perf but it's much cheaper and on a new platform
a 5700x3d will be a significant upgrade from the 3600 and performs on par with the more expensive 5800x3d. worth the upgrade and could still sell the 3600 used to get some money back.
In my country it's a price difference of 40€ .
I would also go the R5 7500F then. 🙂
Yeah go for it :)
7600x is minimum for buying in the US. It’s regularly $190-199 and boosts to 5450mhz most of the time gaming. Performs about 3-5% better than a 5800x3D on avg.
I know Its kind of a weird request but what will happen if you compare i5 8400f with r5 8400f
Haha I’ve been wondering the same thing and I will be doing that at some point
at 1080p the 8400f would have a massive advantage. at 1440p your i5 would start to catch up but the % lows would be horrible. at 4k they would perform very similar in alot of games except your cpu would likely stutter

Or 7500f (tray unit, no cooler) for 185.25€ from Proshop.
In Australia the 8600G and 7600 is $70 cheaper than the 8400F.
This and the whole 8000 series should have been cheaper.
I'd personally love an 8000g machine but you can build better machines with a dgpu at the same cost or less.
There were no big announcements from AMD about these chips, they weren't heavily covered, etc. They clearly are not great and 9k series are the ones that matter (after 7k series).
PS: I know this is a stupid request but I ALWAYS have a hard time understanding PCI_E lanes counts. I know (or think I know) how it works, and bla bla. But I always end up confused. Also because people have said "PCI 4.0 at x8 is as fast as 3.0 x16!" so... if you're on 4.0 but x8... doesn't that mean that your performance is "the same as it would on an older platform even if it's still capable"?
It would be great if you can do a short video showcasing this and how it changes with different cpus and mobos for the same GPU, and the same CPU/Mobo for different GPUs showing the GPUZ like you did here. I feel that simple visual explanation would help me (and maybe others) a lot. You often times make different videos instead of the same topic as everyone else, often times with budget pieces and all and I love that. It showcases a market that is more prevalent than what it would seem. So this PCI lanes talk I feel would be also very helpful for low-to-mid tier buyers that might get confused about this or not taking into account. Maybe there's an idiot out there who pairs something like an RX 7600 with with a B350 and an R5 2600. I swear it's NOT me!
PCIe 4.0 x8 will give the same performance as PCIe 3.0 x16 _if_ the graphics card supports PCIe 4.0.
In most situations the performance difference between PCIe 3.0 x8/4.0 x4 and PCIe 4.0 x8 isn't very large, but it can cause problems for graphics cards with relatively low VRAM capacity compared to their GPU performance. An RX 5500 XT 4GB or RTX 4060 Ti 8GB can lose a lot of performance when limited to PCIe 3.0, for example, and an RX 6500 XT 4GB (which has only 4 PCIe lanes) is even worse. The RTX 2060 6GB doesn't support PCIe 4.0, so I expect that if limited to 8 lanes, it would also lose a significant amount of performance, though I haven't seen benchmarks of the RTX 2060 with different PCIe configurations.
PCIe bandwidth is less important for graphics cards with more VRAM (because data doesn't need to be swapped in and out of VRAM through PCIe as often) and in tasks which run at lower frame rates (because not as many draw calls and other commands need to be sent to the GPU through PCIe). If you have an RTX 4090 and use it for 4K path tracing, for example, you wouldn't actually lose a significant amount of performance from being limited to PCIe 3.0 x8, even though it's much more powerful than some other cards which would be crippled in this situation. Techpowerup tested this, and found that the RTX 4090 loses less than 1% of its performance in Cyperpunk 2077 at 4K with PCIe 2.0 x16 (equivalent to 3.0 x8), compared to PCIe 4.0 x16, though the performance loss is much larger in most other games.
"Maybe there's an idiot out there who pairs something like an RX 7600 with with a B350 and an R5 2600. I swear it's NOT me!"
That person is probably losing about 1-5% of their GPU performance on average from being limited to PCIe 3.0 x8 (the 7600 only supports 8 PCIe lanes, and the CPU and motherboard limit those lanes to version 3.0). The performance loss from PCIe bandwidth would be larger in games which have particularly high VRAM usage but which wouldn't be limited by the GPU, like DOOM Eternal on maximum graphics settings, and old games with UHD texture mods, as these tend to both use a lot of VRAM and run at very high frame rates on relatively weak GPUs and CPUs. But if that person mostly uses their PC for relatively CPU-intensive tasks, they're probably losing more from the weak CPU cores and high latency than from the PCIe connection. The PCIe bandwidth also won't matter much if they're not running close to the RX 7600's 8GB VRAM limit.
I have seen multiple tests where ryzen 5 7500f is a little slower, ppl seem to not see that the 8400f is on 4nm
Is thw zen4c basically E core but with hypersthreading?? Or normal zen4 core but with reduced cache??
Zen 4c is identical to Zen 4, but with components placed closer together. This makes it about half the size, but reduces the maximum clock frequency due to increased thermal density and electrical interference.
It’s a cut down 8500G, with Zen 4c cores.
Is zen4c a bad thing?? How it different from normal zen4?
@@sadatislamkhan3707 lower clocks and Architecture
2x Zen 4 normal clocks + 4x Zen 4c lower clocks also L3 only half of Ryzen 5 7600 and in gamin make difference
@@sadatislamkhan3707 these cpus have less cache. affects performance in some games.
These 'laptop esq' cpu's do have better mem controllers but it doesnt really improve gaming.
Unfortunately these 'f's are salvage and should be priced lower, which will happen later when they pile up.
7500F for $120 on Aliexpress is the smart choice
Sadly the ryzen 7500f isn't available in my country and i cant buy it from aliexpress since ali express is banned here.
The R5 8400F only exists as AMD had a lot of APUs that had problems with IGPU so sale it as a F version but AMD want too much for it. May be worth testing how well it overclocks but with box cooler or a good cooling upgrade.
Try a Thermalright Assassin Spirit V2. It's a very cheap cooler for how good it is.
Test on 1440p please ?
I still have an AM4 chip. :)
Good idea, bad price
Ryzen 5 5600 vs this....which one should I get ?
This is am5 so better upgrade path but honestly I’d get the 7600 instead
Is the 8400f better than the 5700x3D? I believe the 7500f/7600 is already comparable to the 5800x3D.
I think the 5700x3d would be better. For am5 though the 7500f is a great choice
7600x=5800x3d
7500f=5700x3d
The biggest difference with 8400f/8500g is that they have half the cache, and it makes them noticeably worse which you cannot fix by overclocking. So no, 8400f is not better but worse than 5700x3d ON AVERAGE. Still faster single core of course.
1:25 why is the GPU only run at 4.0 8x mode while the specification you've said that 8400f only has pcie 4.0 20x lane? Should it be like pcie 4.0 x16 mode for GPU and the rest 4x is for NVME? Sorry for the confusion I don't understand
it would appear that the iGPU still connected uses up PCIe pool
@@BenAkenobi what I know is that iGPU doesn't use PCIe lanes unlike dedicated GPU so I assume either the motherboard or the cpu just couldn't handle the power of 4070s. Or maybe even have another pcie expansion card installed but i don't think that's the case.
@@magim2039what you know is wrong because an iGPU is still connected via pcie lanes.
You're forgetting the supplemental chipset on the board requires x4 PCIe.
@@arcticowl1091 Really? AMD CPU G series is known for the cut-down PCIe lane specs. The previous 5600g only support 3.0 16x GPU lanes (other 8x is for nvme and chipsets) and the other 5600 supports 4.0 (16x for GPU and 4x for nvme). And also the same thing with the 7600 (gen 5) with 8600g (gen 4). But not too sure if the 8000 series especially F version could run at full gen 4.0 16x PCIe lanes for the GPU.
(I'm currenlty using 4600g and my gpu RTX 2080 Ti runs at full PCIe lanes 3.0 x16 with another 4x gen 3 NVME total of 20 PCIe lanes to CPU only)
The source of specs is from TechPowerUp
So maybe the iGPU will use the PCIe lanes if the iGPU and dedicated GPU is being use at the same time but based on my research, iGPU does not need PCIe lanes for data transfers. 1:25 This is something that I just dont understand.
Would somebody still build a brand new AM4 system now? You can get a Ryzen 7 5700X3D + motherboard + ram for pretty cheap now (MicroCenter has an AMD combo deal of Ryzen 7 5800X3D, ASUS TUF Gaming B550 Plus WiFi II DDR4, G.Skill Ripjaws V 16GB DDR4-3200 Kit for just $330! I wish I had a MicroCenter near me. Damn). Very limited upgrade path though. Maybe this 8400F will get discounted.. maybe making it a good "base build" for somebody wanting to build a new AM5 system with upgrades in the future. Though you still need a dGPU, which hurts that idea.
I would, for a low-end PC, if I didn't care about future CPU upgrades.
If I did care about upgrades (which I do), I'd get a 7500F and Maxsun B650M from Aliexpress instead, as it's not a lot more expensive than a 5600 and mainstream B550M, but is a bit faster and the motherboard will support next-gen CPUs.
@@nathangamble125 My problem with upgrade path is.... except for GPUs, I tend to use PCs for several years before upgrading. And then I usually buy a totally new platform by then. I wonder how many people worry about upgrade path when they buy but then never do.
The 8400F is the 4500 all over again… If the 8400F were cheaper than the 7500F, I could understand it. But considering you can get the 7500F for like $130 on Aliexpress, the 8400F just comes across like a scam product. Its sad how many products like this with misleading and confusing names exist and end up entrapping less informed consumers.
Holy crap AMD is really down binning their silicon now
It's called milking the market. A "faulty" APU. But it's not a bad thing to find use these for these "non-passed" APU silicon. The problem with this, is just that the price is too high.
Same thing with the Ryzen 7 5700(5700G withput iGPU), which is priced very closely(cheaper) to the 5700X. They hope people don't know the tech specs, and only see the model number.
It's worth noting that this is based on "Phoenix 2" instead of "Phoenix" , and it actually has only 2 Zen 4 cores, with 4 Zen 4c cores! Only noticeable difference in games is that the Zen 4c cores clock lower.
No, it isn't. Stop claiming this, it's blantly not true.
The 8400F has 20 PCIe lanes.
The Phoenix 2 die has only 14 PCIe lanes, so the 8400F cannot possibly be based on Phoenix 2. AMD's website also says the 8400F die is 178mm^2, while the 8500G (Phoenix 2) is 137mm^2; though they do also list the 7540U as being 178mm^2 (possibly they use Phoenix 1 with 4 cores underclocked and PCIe lanes disabled, and Phoenix 2, for the 7540U interchangeably, depending on binning)
These leftover AM5 processors seem to be really sketchy with these limited pcie lanes.
That's more due to the fact it's a laptop processor.
@@nesyboi9421 Can you point me toward a laptop with this CPU in it? I'm having trouble locating any.
