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

History for llvm/lib/Target/AMDGPU - llvm/llvm-project

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. - History for llvm/lib/Target/AMDGPU - llvm/llvm-project

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...

Given that they position it against their own 7900XT implies it likely won’t be cheaper than $650. At that price, it’s not going to do anything to shake up the market and I expect consumers will be pretty meh about it. Maybe even angry since people still have this notion that it’s AMD’s job to keep Nvidia in check, all while regrettably paying the Nvidia tax at the end of the day.

It's not that AMD's job is to keep Nvidia in check.
It's that AMD's job is to provide people with affordable and great price/performance cards.

Their job is to build a $3k halo and kill someone with it.

The only person that's going to kill is Lisa su lol

Which is why it's never happening. But it's their job still.

No, it's AMD's job to make sure they make money on the products they sell. Same with Nvidia or Intel. Business 101.

 

[Tuna-Fish]

It's starting. Remember kids, take a drink every time you hear the word AI.

 

[RnR_au]

No Lisa? Wut?!?!?!

 

[RnR_au]

RDNA4 will be 'discussed' later this quarter apparently.

 

[Keller_TT]

AMD: RDNA 4 launching in 5...4...3..2... 5...4...5...4...5....5... Nah.. we'll be back in 5 months. Lol.

 

[blckgrffn]

Soooooooooo..... .

eyes giant gpu box

I guess I can just install this now, eh?

 

[jpiniero]

AIMD, amirite?

I’m so excited to give you an answer to this question…..


Later this quarter!

Well at least Halo Strix is official and they sort of benchmarked it's GPU performance - 140 % faster than Intel iGPU...

But what is the PPA?
PPA is the only thing that matters to AMD.

Every person, company, etc, has their place in this world. AMD's place is as a budget company for the people.
AMD is, and will never be, like Nvidia, cannot be treated the same way at all. CPU is an exception due to how historically terrible Intel has been, otherwise, it would've been the same.

 

[lucasworais]

Lmao, what happened?

 

[soresu]

Not gonna lie this is well beyond taking the pièce de résistance now.

Indeed it does.

Nope.

CPUs they build big. They don't do that in client graphics.

 

[gdansk]

Hmm. I really expected RDNA4 info by now. When's the next time they could talk about it?

 

[del42sa]

Lmao, what happened?

AMD never misses a chance to miss a chance

Proven 👍

 

[carrotmania]

I've fought for AMD for a long time now, including 580 being a decent mid range card, and most every CPU since Ryzen (I'm still running a x370 with a 1700X > 5950 in it)... but they are taking the wee wee with RDNA4. Something has gonna majorly wrong in their GPU division. Ms CEO of the Year needs to get her house in order.

 

[JustViewing]

I guess software is not ready.

 

[lucasworais]

Maybe they found an HW bug again and this time they decided to scrap the whole lineup in the last minute lol

 

[gdansk]

I guess software is not ready.

This first time in Radeon history they wait to launch for lack of working software? They really are changing things at AMD.

 

[adroc_thurston]

I guess software is not ready.

They don't have a winner and they can't put a price sticker on it
