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

Or Phoronix

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...

They can only do so much when the 80% of the market they did not own suddenly decided to pounce.

Each manufacturer only having one single token card anywhere near MSRP is not much better than Nvidias fake msrp tactic.

Like 400 people in line at MC here in MN one hour after open.

This is not the release AMD promised us.

AMD is probably just glad they sold through 2-3 months of shipments in a moment.
Sucks for gamers though but no one likes them.

Im tilted beyond scope... My f... amazon business bugged out had 825euro 9070xt mercury magair oc in cart they had 300 in stock releged GONE.... Panick buyed 9070xt taichi for 900euro (((((

Dang, even when the bang per buck needle moves in a pro-consumer way, scalpers have to ruin it all by buying up the supply and then jacking up the price. Screw the scalpers, seriously. I just looked on eBay and they’re all listed for like $1000…

 

[DownTheSky]

Amd needs to read the market better. They had 3 months, could produce millions of chips but didn't. Guess what they all would have sold out.

 

[adroc_thurston]

Yeah that sure as hell worked with Hawaii 11 years ago.

 

[gdansk]

No, they could not. They still can't keep 9800X3D in stock. And what would you prioritize?

Even if they had increased the amount of N48 they are making after realizing 5000 stock was low (and when was that obvious?) how long does it take to go through TSMC, packaging, printed and populated boards, and finally to the warehouse?

No you don't understand supply chain is magic and you can just snap fingers and it works.

Get your business brain on.

AMD has like 15% market share. What are they gonna do, double or triple orders and gamble having loads of excess inventory? They could increase production by 50% but if Nvidia hasn't provided the market the usual supply and everyone across the market is looking for a card it's gonna sell out. Of course it's gonna sell out.

I don't care. AMD said things that didn't come true. AMD is not a person, it doesn't have feelings. There's no point defending the outcome.

Consumers were promised something that didn't materialize. The end.

 

[inquiss]

What was the lie? They had a ton of stock. More than normal. What's the lie exactly? Did they promise to make enough cards for the whole market this month?

 

[inquiss]

Yeah that sure as hell worked with Hawaii 11 years ago.

It's like some people here have no idea how long it takes to build and ship cards. Especially considering the uncertainty around nvidias response and the implications of oversupply. We've been here before!

 

[fastandfurious6]

🤣 selling like hot cakes! it's a big middle finger to nvidia, everyones tired of their BS lol

It sounds like you've invented a promise you think AMD made and then are hurt they didn't live up to the invented promise. We can bust that notion though, if you can state what promise you think was made and how it was broken. Some specifics, you know.

Is the promise in the room with us now?

No, in Australia the stock wasn’t even enough even for an ant.

1000+ shipments really in one state is not enough. These GPU companies are not allocating enough wafers to gaming GPUs.

Come on, do you really thing everyone in the world suddenly become a gamer?

GPU is more than just an undiced N4p wafer.

 

[inquiss]

Well, quite. Though of course this dodges you explaining why you're having an emotional response (and I don't mean this as a slight, it's just what's on display) to something that doesn't have a factual basis.

 

[poke01]

GPU is more than just an undiced N3p wafer.

What else is in short supply another than sillicon?

The problem is that the market leader isn't allocating enough wafers to GPU and people blaming AMD because they didn't suddenly take the view that they should provide the majority of the market now.

You think anyone 12 months ago would have not been laughed out the room if their plan was to increase GPU supply 5 fold because Nvidia might not get the launch right and that AMD needed to be ready with supply, just in case? This is what you're asking AMD to have done...

 

[inquiss]

Madness from AIBs... AIBs would not have made commitments to build 5x times the GPUs and committed to purchasing them because..that's crazy... Supply chain can't take on short term shocks like this from the tiny player.

Supply is AMDs worst trait. Anyway most of this is on NV.

But to AMD and NV the USA is all that matters. Not Europe and not even Asia.
