Discussion RDNA4 + CDNA3 Architectures Thread

[DisEnchantment]

With the GFX940 patches in full swing since first week of March, it is looking like MI300 is not far in the distant future!
Usually AMD takes around 3Qs to get the support in LLVM and amdgpu. Lately, since RDNA2 the window they push to add support for new devices is much reduced to prevent leaks.
But looking at the flurry of code in LLVM, it is a lot of commits. Maybe because US Govt is starting to prepare the SW environment for El Capitan (Maybe to avoid slow bring up situation like Frontier for example)

See here for the GFX940 specific commits

There is a lot more if you know whom to follow in LLVM review chains (before getting merged to github), but I am not going to link AMD employees.

I am starting to think MI300 will launch around the same time like Hopper probably only a couple of months later!
Although I believe Hopper had problems not having a host CPU capable of doing PCIe 5 in the very near future therefore it might have gotten pushed back a bit until SPR and Genoa arrives later in 2022.
If PVC slips again I believe MI300 could launch before it

This is nuts, MI100/200/300 cadence is impressive.

Question - Speculation: RDNA3 + CDNA2 Architectures Thread

Man I have been dying to make this one for a while now. First rumours for RDNA3 are here so new thread time! Just going to start off with this one for now: kopite7kimi on Twitter: "@VideoCardz Ah, I mean a simple mcm design with 10240 cores is not enough. Because the lift from RDNA2 to RDNA3...

AMD pretty much admits that they struck out getting N48 and N44 into laptops.

 

[Heartbreaker]

Close to 7900XT, that what AMD graphs was, but that was 900$ or street price for 7900XT?

So much for that crazy theory that AMD was delaying them to increase their prices.

Not that this one makes a whole lot of sense either. $900 for what might be 4070 Ti Super performance. Even if NVidia went into a coma, and AMD was only competing against the 40 series, I don't see that doing well.

Isn't here we discussion half year ago, about there no RDNA4 for laptops?

 

[blckgrffn]

Yeah, and the way forward for AMD in laptops is via APUs of all flavors, the discrete GPU will live in laptops but in ever higher performance tiers.

That would be really surprising, given all that nonsense about TAM and also renaming the card to 70s series.

7900XT is ~630$ for several month now and its coming with 20GB of vram. If its marginally faster but with 16GB, anything above 600$ is instantly DOA.

 

[exquisitechar]

Yeah, that seems like nonsense and doesn't fit what AMD has said about the card. They've lost their reason if they actually intended that to be the price.

 

[maddie]

We're wasting time discussing random individuals looking for their 15 minutes of fame.

The naming, the moderate BOM and Nvidia's underwhelming performance increase, suggests that they're looking to raise prices, not lower them. When the public see how Blackwell's mid-range performs, it'll be an easier sell.

My thinking at least.

 

[Gideon]

So much for that crazy theory that AMD was delaying them to increase their prices.

Yeah that made 0 sense anyway. It takes 5 minutes to increase the price in a spreadsheet.

There is of course all that mental gymnastics about "waiting for nvidia to go first" but that also doesn't make much sense. Particularly as people are talking about *preorders* in the second half of March.

That's a loooooong wait for questionable benefit

The only thing that ever made sense to me is the software was not really in good enough state.

SW is never really done, never bug free, and never fully optimized. It's just shipped when it's considered acceptable (often barely) to meet target date (that probably already slipped). This is much more prevalent today, where it's easier to deliver patches later.

I'm guessing someone made a call, that they really needed more time to improve it, perhaps prompted by NVidia showing even more improved DLSS 4, to widen the gulf.

While you can ship patches later, that first impression from reviews will linger.

 

[SolidQ]

SW is never really done

I think software without bugs, gonna be in far future with AI power.

NVidia showing even more improved DLSS 4

Yeah, DLSS4 also might be reason, there also was complaining NV driver not fully rdy to launch

 

[Heartbreaker]

Totally looking forward to bug free Skynet software.

At least now we know it's gonna cost less than the 7900 XT. Releasing it late AND higher than 7900 XT's price would be dumb. I hope AMD does not prove to its detractors that it is incompetent at setting launch prices.

My guess: $579 to $649

i don't think we will be alive in this time, but who know maybe in 10-30 years AI speed gonna massive increased.

My guess: $579 to $649

My guess 500-530 for vanilla, 600-650 for XT

AMD never misses an opportunity to fail honestly. They always try to price way too high, get negative reviews, then drop price later on to more reasonable levels.

Why not pull an Nvidia and set an MSRP that is lower and then let demand increase the price? At least they'll get favorable launch reviews that way.

Nvidia uses fictional MSRPs. AMD uses aspirational MSRPs.

New AMD stuff tends to launch at worse performance/buck ratio than the stuff that is going out. It's to be expected, given that the past-gen product is usually discounted 20-30 %. You can't really keep matching that, since your MSRPs would quickly hit 0 if you did.

If it was Nvidia, people would say the price premium is for "technologies" and "features"...

People would bitch the same. It's just the norm. New kds come to the internet, see the memes, repeat them to fit in. Everybody is used to complain or trash AMD so that's the first reaction to anything, regardless of it making sense or not. I bet people would find something. I don't think people think-through their quick takes posted to ex-twitter, reddit or the like much if at all, the comments are often so ridiculously missing the point or clearly nonsensical... it's that first emotion/predisposition that is like 90% of the opinion of most people. So that's what you get, usually there will be comments saying something about "50 $" (the literal phrase is repeated so often... if that was guerilla Nvidia marketing starting that, they really had a success there) or "AMD should just give up".

oh, I forgot, it's not faster, but hey it has AI ! 👌

 

[gaav87]

Well there are already drivers with fsr4 and 9070xt support where the x is the annoucement or anything ? Like i have the drivers for past week... Gotta bribe some warhouse employes i guess

 

[Jan Olšan]

Also the performance in ray tracing games. Usually was said to be the reason why Radeon card has to be cheaper / why Nvidia card being more expensive isn't really more expensive etc. Gotta see if that is going to fly with the RDNA 4 cards (assuming the RT performance is improved...)

Some bulgarian msg me and said the translation was wrong. 9070xt was 799$ w/o tax but with shop profit so in reality msrp of ~700euro/usd.
The 7900xtx was 899$

 

[igor_kavinski]

msrp of ~700euro/usd.

Still seems kinda high unless it is magic (does everything you would expect from an RTX, including running CUDA software).

Make sure you run it offline only. Don't make the poor warehouse employee lose his/her job.
