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

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...

9070GRE falls where you'd expect. I don't know what's up with some of their results. Either drivers, or they suck at testing now that Gordon is RIP.

Steve and Tim discussing how more reviewers are also finding the fine wine results. Steve shilling was never the right answer.

Did N36 ever tape out ?

Outside of RGT no one has leaked about it ??

Very interesting. Could just be a “to the moon” clocks version of n31 but maybe they decided the power scaling was poop and to go 355w for the reference instead. There was a lot of drama about the size of the ada cards at the time iirc. AMD made a big point about it being a “drop in” upgrade 2x8 pin during that rdna3 reveal.

24 days into July and no driver update. Is this normal? Isn't there usually one update per month? I'm hoping (coping) that it's taking time because they're planning something big like Redstone

Lately the Radeon driver releases have been coming later in the month, at least for the full WHQL versions. Maybe they are just a bit late getting them out at times.

Can I get the quick version? Did Tim go back to defending proprietary tech or something?

That an interesting test.

-The guy with the full beard is the "straight man" who keeps saying deeply ignorant things so the guy with the short hair can correct him, because these videos need to have that conversational format to work.

It just comes off as silly.

Microsoft screwing with AMD drivers again. It bit me.

https://www.reddit.com/r/AMDHelp/comments/1m7twzq/my_amd_version_is_251016_which_is_odd_because_it

I've been having all these weird stuttering (youtube), monitor flicker, monitor blackout (sound still works), etc. It seemed to do better if I used more than one display.

Upgraded (downgraded from windows ) to the beta driver and it seems much better.

Never seen this windows update bug happen to my nVidia machines?

Edit: actual driver update text "Advanced Micro Devices, Inc. - Display - 32.0.13031.2000 (2) 6/26/2025"

 

[Ranulf]

I'd say it is just typical windows idiocy that occasionally happens. It has been a few years since I've run AMD drivers on a daily use machine though. In my experience over the last ten years, as long as you have the manufacturer driver suite installed, windows generally behaves and doesn't install drivers on its own.

 

[Schmide]

I do DDU and get drivers from AMD before windows gets its hooks in. The MS driver is newer than even the beta driver on AMDs site. 100% MS screwing up.
