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 :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...

Erase HD4870 from history and the world would change. At once.

AMD was in a bad place financially after overpaying for ATI and the delay and disaster of the 2900xt. With Intel being a strong competitor at the time capitalizing on the success of the core 2 duo and it's successors, AMD was losing billions annually at the time as a result of maintaining their FABS which they owned at the time.

They didn't have the money to create a risky product like the 2900xt again.

Big chips can have alot more go wrong with them as history has shown. AMD didn't have the money to develop a flagship to go along with the 4870. AMD finances were catastrophically bad. People may argue that if AMD still made monoliths that went after Nvidia's flagships during this period, AMD may of ceased to exist today. Many would argue going after the mainstream saved AMD graphics as some recollect here.

AMD still maintained marketshare and gained upwards of 40% percent during this time. Same with the 5800 series afterwards. I would say up to hawaii, AMD could still maintain 33% marketshare while just being a little bit cheaper than nvidia. Not bad considering AMD was spending a lot less on R and D.

I feel where things went sideways for AMD was Vega 64's launch. This was where AMD lost their credibility to make graphics cards and everyone started to not bother waiting for their products anymore.

Vega 64 came out 15 months after the 1080(one of the latest launches ever), while being similar speed and using dramatically more power. It was an epic failure considering there were rumors it was being sold at a loss and the hype of the product prior to launch. AMD destroyed their brand with enthusiasts and the general public alike. Their marketing at the time, made it look like they were going to launch something spectacular.

When the 1080 ti came out to much fanfare, AMD fans and marketers doubled down and said to still wait, Vega 64 was still going to be faster. The launch of Vega 64 made AMD look last generation and terribly behind. People on forums, youtubers alike that would defend AMD and said wait for Vega looked like fools. It made Radeon graphics look third rate and people were calling for Raja's head. This is where AMD began to bleed marketshare and since this launch was right around when Lisa Su took over, it made sense for her to throttle the division since the rest of the company was in trouble at the time.

chungus dies aren't risky at all.
If anything G5 and their shrink cadence for Evergreens was a lot more dangerous.
They were just idiots and sold themselves cheap.

And when the time came for ASP hikes with Tahiti (hallo $550), there was a riot. Lessons learned.

She didn't throttle anything.
GFX guys always get the buxx.
It's just that they're not allowed to gamble anymore. Navi4c was the last time they could put something truly audacious on the roadmap.
