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...

Just RDNA4 things really.

Things we will see in N44/N48 or things that were unique to the stacked parts?

 

[Joe NYC]

It was above 200.
A fair bit actually.

Oh no!

 

[adroc_thurston]

Oh no!

Now this post is definitely not getting shown.

Oh no!

RGT

I mean, let's look at the positive.
Since they all go and use YT servers to read the forums, at least the forums get less pressure.
(yesterday was pretty awful)

Wait hold on here, his video is a goldmine of an IQ test.

600% increase in RT to be on par with Blackwell.
You heard it at RGT's first!

"Intel is just better as Alchemist has proven"
"AI doesn't care about latency so just kill the latency with your latency heavy chiplets"

Someone who as a real 6900xt that really exists and as no reason to buy anything but Nvidia but as a 6900 xt because here is no reason to buy high end AMD.
He could stand to ave a english lesson too.

Spoiler

Before someone says "it's lowbrow to pick and mock them", hey they started picking things here first, it's only fair. And funny.

"Intel is just better as Alchemist has proven"

It only requires twice the die size to run at the same perf as the 7600. And only in games that it can actually run. kek

Exactly! Total success and absolute proof of superiority over the AMDumbs.
