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...

Wait till you see Apple RAM prices.

Knowing Apple they locked in supply years ago. Not that that will stop them from bumping prices a bit just to get a little bit more.

How much slower are these 9070 non xt models I'm seeing at NE? About $100 cheaper for some models compared to the XT version. Cursory glance says it is just gpu clock speed.

Lets see if they do, the memory pricing for the M5 Pro/Max next year should tell us a lot about where the market is heading . If it increases from $200 per 8GB, I don't think the market is going to get better at all in 2026.

At least companies like apple, sony sell in mass quantities, its DIY users that will get beaten the most

Its Apple, even if they have a decent supply of ram stored up they will take advantage and raise prices if possible. It definately looks like it will be worse for 1-2 years than it was with the DDR4 shortage in 17-18.
