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 :grimacing:

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...

Given that they position it against their own 7900XT implies it likely won’t be cheaper than $650. At that price, it’s not going to do anything to shake up the market and I expect consumers will be pretty meh about it. Maybe even angry since people still have this notion that it’s AMD’s job to keep Nvidia in check, all while regrettably paying the Nvidia tax at the end of the day.

It's not that AMD's job is to keep Nvidia in check.
It's that AMD's job is to provide people with affordable and great price/performance cards.

No, it's AMD's job to make sure they make money on the products they sell. Same with Nvidia or Intel. Business 101.

Every person, company, etc, has their place in this world. AMD's place is as a budget company for the people.
AMD is, and will never be, like Nvidia, cannot be treated the same way at all. CPU is an exception due to how historically terrible Intel has been, otherwise, it would've been the same.
 
I've fought for AMD for a long time now, including 580 being a decent mid range card, and most every CPU since Ryzen (I'm still running a x370 with a 1700X > 5950 in it)... but they are taking the wee wee with RDNA4. Something has gonna majorly wrong in their GPU division. Ms CEO of the Year needs to get her house in order.
 
Maybe they found an HW bug again and this time they decided to scrap the whole lineup in the last minute lol
