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...

The cards are reasonably priced (considering the market) and widely available here in Brazil.
The cheapest 8gb model I could find is at ~$450 and the 16gb at around $530.
For reference, the cheapest 5060 is at $450, the 5060ti 8gb at $540 and the 16gb one at $685.

Just watched the Daniel's review of both 8 and 16 gb 9060 xt's and I wonder why I'm not surprised to see the HWUB salty comment there )

Salty about what? It was clearly dripping with sarcasm.

Yeah, it'd be better to say that his trolling seemed a little nervous to me.

Honestly, I am not as angry as some are regarding 8gb VRAM for some SKUs. I get that those cards don’t run the most demanding games at the highest settings.

Consoles tend to hold back progress a lot, so until we see 24-32gb of memory, we likely won’t see any real issues beyond PC specific titles.

I get the reason reviewers are hounding AMD/NVIDIA, however. My only real beef there is that at least AMD included a PCIE X16 interface.

If you thought about how it's a waste of a perfectly good GPU with VRAM that cannot be upgraded or replaced, you would be. There's absolutely no good reason to hobble a 9060 XT with lower VRAM. They should've reserved that amount of VRAM only for RX 9050 XT and maybe 6GB for RX 9040.

What 9050 and 9040?

I'm expecting them to release those because why not?
