AMD Radeon RX 6400 Tested on PCI-Express 3.0

[thelawnet]

If you exclude the few exeptional games, the difference is actually pretty neglectable.

I also find the games selection pretty off. Most are practically unplayable (under 60fps at 1080p). Kinda missed the target audience who buy these cards, playing for the most part lower demanding multi player games like CS:GO, Valorant, League of Legends, Apex Legends, Dota 2, Overwatch, Dead by Daylight, PubG, Fortnite, TF2, Payday2, War Thunder, Rocket League, etc.

no.

under 60fps at 1080p is not unplayable.

settings go down to 30fps for a reason.

gpu price inflation means that people absolutely will use these cards to play the most demanding games, and they will do so at 1080p low, and at 30fps if need be.

in countries with lower incomes you can get game pass (or pirate) for low prices, but when a 6400 costs a month's minimim wage, then people are going to compromise on fidelity/framerate, not just say 'gee, i best stick to abandonware, and esports',.or spend two months' wages. those esports users are in any case often gaming on used 750 ti, gt 1030, etc., so the entry level new gaming carss are absolutely for aaa games

There's also a lot of people buying low end GPUs for the purpose of playing modern games besides the titles you listed, and for them keeping 60fps at all times may not be that important. Remember these reviews uses max settings, I'd imagine many of them could get around 45fps with some tinkering and still look good and that is fine. Maybe even 30fps is ok.

Exactly. Even with a 2070 in my main rig, I still find 30 fps acceptable. Not everybody is a CS:GO maniac / esport competitor.

So as I said before this card was released, it would be a 720p gaming card at best and it's actually the case. What a waste of space by AMD, who would waste their money on this?

I did. It's a pretty decent HTPC card actually, plus the possibility for some light gaming (not AAA max settings 60 fps of course). Only if it was a tad cheaper, it would actually be worth it for normal users as well, besides curious geeks like myself.

Next year AMD are going with single wire connection to the PCI-E.

I did some math with old TPU reviews, and this card on PCIe 3 is slower than my 7950 OC was 10 years ago. A prospective buyer could have just bought a blower 7950 from the trash bin for $50 5 years ago and be set. What an absolutely pathetic joke.

And when I bought that 7950, any GPU over 5 years old literally would not even be able to initialize a single new game.

 

[Max(IT)]

This kind of products should just stay on the shelf. Low end GPUs have absolutely sense, but solutions like PCIE 4x lanes are offensive for customers. Thanks again Lisa Su for her new idea about what AMD must be

Unless the prospective buyer can't fit that 7950 into their slim case. Or they want new drivers (look at how Halo Infinite runs on the 7950). Or better efficiency / heat / noise. Or modern video decode capabilities.

Gaming performance isn't the only measuring point of a graphics card.

 

[Denver]

Sorry, but it can only be a joke to compare a new GPU with a multi-year warranty to second hand GPUs, probably from mining. XD

The RX 6400 is not good or revolutionary, but it is the only "usable" GPU in this price range.(Unless the RX 5300 is still available)

I understand that benchmarking in MP environments is a tricky one, but it should be adressed somehow to get some meaningful tests.

Yeah, but the target audience won't ever use a pretty good CPU such as the tested Ryzen 7 5800X with this card.
You will find an old Core i5-6600 with RX 6400. That will be one very awful system.

 

[GoldenX]

Even then, having a low end product get over 30 FPS at maximum settings in the worst case scenario is unheard of.
Usually, low end cards were equal or worse than integrated ones, this is the first time we have cheap stuff that can actually game.

Still, taking the encoder, and using the worst decoder ever is too cheap.

Remember these reviews uses max settings, I'd imagine many of them could get around 45fps with some tinkering and still look good and that is fine. Maybe even 30fps is ok. And they probably have older, lower end systems. The H110 and H310 chipsets only supported PCIe 2.0 which would absolutely cripple this card.

Well, my point was that it would be more interresting to test games that the targeted audience actually sinks the most time in, which are mostly lesser demanding MP games.

If 30fps is acceptable is up to eachs own standards. I couldn't do it anymore. The "my game runs like crap" crowds in forums can't either.

You can get a 5600x for around 200 bucks, which is on par with a 5800x in games. So I think the hardware selection does met most of the target audience.

People don't think like this - they would only upgrade one at a time. So, no, they won't buy the Ryzen 5 5600X with a new motherboard, memory, CPU fan, etc. full upgrade..

target audience for this is a i3-12100f. no one would buy this for a 7 year old CPU, you'd just buy a used card go with your used CPU.

a 2015 vintage pc is going to have a gpu in it already, and likely not much slower than this (maybe faster), so you would not buy this.

this card is fine, just needs a price cut of around 25%.

 

[ARF]

target audience for this is a i3-12100f.

Wishful thinking.
What if it is the Core i3-10300?

 

[thelawnet]

Wishful thinking.
What if it is the Core i3-10300?

why would you buy a 10300?

IME people building PCs on a very low budget use the 10100f or 10105f.

let's assume you mean that, in that case well this is the same price as a 1050 ti, so if those were your choices then neither are great but that's the state of the pc market now. i couldn't really say one is definitely right or wrong

if this card got a price cut to make it 25% cheaper, then even with the pcie 3 then this would be a clear choice, because it's then the cheapest new gpu, and even with throttling in some games, it's still clearly faster than the 1050 ti.

 

[ARF]

I am afraid those extremely high graphics cards prices (159$ for this iGPU-class performance) actually include the loss of value of the petrodollar, you know inflation because of printing money during the pandemic...
The question is - is the inflation calculated as 100%?

 

[Fast Turtle]

If it had hardware encoding support for Zoom/Teams, it would be a viable business card but since it does not, it's not worth what ever AMD wants for the card from a business standpoint. Sorry AMD you screwed up badly offering this without any hardware encoding. The same issue affects the 6500 card and makes it useless to the biggest market - Corporate users.

 

[MxPhenom 216]

I remember commenting when news broke that more cards would be coming running smaller bus widths from PCIe and i made comment that this is going to be a hit to performance for pcie generations older than the cards spec and had a few tell me it wont be that bad of a hit. Well for even a low end GPU a roughly 15% hit on performance going down to pcie 3.0 is definitely not nothing.

 

[ARF]

Yes, it is so disappointing. It is in a GTX 1050 Ti ballpark.

Thanks for doing this. It would be interesting to see how settings can affect this scaling since on 3.0 I can get 60fps on Halo Infinite at 1080p with low settings. I don't think anyone would actually play it at 7fps with your settings.

I won't even play Halo Infinite on a 3070Ti, you're playing it on an RX 6400?

Wow.

 

[ARF]

I won't even play Halo Infinite on a 3070Ti

Why?
~50 FPS maxed out at 3840x2160. Much higher FPS if you change a setting or two...

 

[Mussels]

I can do that. What game eats the most VRAM nowadays?

I'm totally unsure!
See if you have any games from the charts, that showed big differences?


It's one of those little niggling details in the back of my mind, that GPU's with lower VRAM (or simply less of it) are more affected by system ram speed - back in the DX9 days it was big, since DX9 cloned the data (storage>CPU->RAM->VRAM vs the modern storage->CPU->GPU, and soon enough NVME->GPU)

When DirectStorage comes out, it'd be fascinating to see how crippled GPU's like this (x4 link, 4GB VRAM) are affected by system RAM speed, NVME speed and such.
The knowledge that a high end GPU makes you need fast system RAM less, would be invaluable when building new systems (if the theory pans out) - Or the opposite, as the results may still show

Well, I made a post in the 6400 review topic using 16 GB single channel RAM. I can retest it using dual channel, and/or standard JEDEC speeds.

I'm not sure how DirectStorage will affect performance, as NVME is on 4 PCI-e lanes as well. It'll definitely have an impact using SATA drives, though. It'll be interesting to see.
