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...

The irony. The place where you quoted all these graphs just did a followup basically agreeing with Steve. Steve will not have to do an investigation.

Edit: In a strange turn of fate, the techspot review is done by a Steven. Well at least we can tell him appart from the other Steves. Until we watch Rick Steve's europe then we get all possessive.

Any hints/leaks/clues about Radeon PRO AI R9700 ???

(Also, I clearly remember announcements and news headlines quoting the card as W9700. When did it become R9700 )

Is @adroc_thurston excited about the 9080 XT 32GB GDDR7?

Client graphics is a ghetto for poor people so who cares about that.

I am committing to Bazzite today on my 5600X3D+RX 6800 system.

Another guy's positive experience: https://www.overclock.net/posts/29482450/

Ran Fallout New Vegas using DXVK earlier today on Win 11, applied a lot of performance fixes and anti crash handling optimizations, game works but is a stuttery mess yet these mods were supposed to fix that.

Under Linux, you install the game, run the game, smooth as silk like we had never truly experienced even 60FPS smooth before.

I'd like to say that MS has utterly and completely dropped the ball.

Unfortunately AMD likely owns no small part in this as their proprietary (gaming) GPU drivers are being deprecated on Linux for good reasons.

That being said, both DXVK and Zink dev teams are basically laser focused on Linux perf and compatibility, with the Windows use case as only a secondary consideration.

They are made with Mesa/Gallium in mind, and I doubt they will ever work truly 100% on Windows drivers.

If I'm talking out of the crack of my posterior and anyone here knows any better please feel free to correct me on this, I'd love to hear more about DXVK and Zink on Windows.
