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

More AMD "GFX940" Enablement Work Landing In LLVM - 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...

Does this card look like 449$ card to you guys ?
To me it looks like 900euro card

Does this look like a $400 card to you? Cause it's a 5700xt and the MSRP was definitely $400.

Impossible, it has three fans AND rgb. No way they could sell it for less than 900.

 

[Jan Olšan]

IIRC Jan 22 is supposed to be the embargo date. Really wondering why partners are leaking so much. 🤣

It seems clear that dates have been shifted. The january 22nd-24th embargo lift days were tied to launch event on jan 15th which as we know did not happen.

TL;DR all the leaked dates from prior to jan 15 are invalid now.

 

[Jan Olšan]

Wonder what could happen if you slap a 28G GDDR7 onto Navi48 and ramp the TBP to 350W.
Wouldn't that be really funny.

Will not happen. The SoC would have to include a dual-support memory controller from the start, in which case why not launch with GDDR7 in the first place?

Extremely unlikely the die can work with GDDR7, don't expect this.

asrock 7900xt taichi launch price in poland was 1330euro cheapest price 980euro
asrock 7900xt phantom launch 1350euro cheapest price 700euro (december)
asrock 7900gre did not even have, a taichi version.
asrock 7900gre steel legend launched at 800euro then went down to 650euro
649$ *1.23 +100euro for taichi better cooler =~900euro
549$*1.23 +100euro =~750-800euro

I see 584EURO launch price in 2020 not adjusted for inflation

Cost more.

Could be. It looks like a lower power dual slot card.

So taking inflation in asrock 5700xt 8GB phantom d oc launch price of ~580euro in 2019 would cost 841euro in Poland today 2025

-The implication of your original post (from my perspective) was because the 9070xt has a massive RGB cooler on a three slot model that it must be more expensive and therefore competing in a higher performance bracket.

I'm just trying to demonstrate that cooler size and RGB does not mean that we can safely assume anything about card pricing or where the card was intended to slot in the price stack.

As far as I can tell, the ASRock Phantom D RX 5700 XT OC only had a slight bump over MSRP here in the US, $430 or so.

- 2.7 slot card, ackshually.

Picture doesnt do the Z-axis of the card justice.

Every-one taking 9550pro price that was based on chiphell pre ces of 449$ and 549$ so saying taichi will cost between 750-900 euro is not insane its like everyone forgot europe has 19-25% tax.

 

[akugami]

Can someone phone AMD and tell them they have RDNA4 graphics cards to announce?

I phoned Lisa. She asked me how I got her number, and threatened to report me to the po-po if I ever called her again and then hung up. So rude!

That was the robot. You should have left a message after the beep.

RT for Gameplay? That's new

DOOM: The Dark Ages uses ray tracing to enhance gameplay, not just visuals

DOOM: The Dark Ages is on track to become one the best-looking games of 2025 thanks to DLSS 4 and Path Tracing. It's also using RT to enhance gameplay.

Oh no... The last thing this game needs is all those RT/PT/FF/etc gimmiks.

-I was wondering when stuff like this was going to start happening.

AMD's got 10% of the dGPU market, so that means that the various AMD AIBs are splitting that already small market share 6 or 7 ways.

Must have been lean times at some of the less popular AIB designer's places.

Just a matter of time till we have NV founders and MBA cards, why let these third parties take a slice of the pie? Chip maker can either pocket the savings or pass them on for competition's sake.

nVidia charges more for the chip and memory than an AIB can make a card and still make a profit (at the MSRP). They probably make more money having the AIBs make the cards.

The FE cards must be a small % of sales so they can sell the idea of the MSRP.

 

[Abwx]

The FE cards must be a small % of sales so they can sell the idea of the MSRP.

Quite the contrary, because they have a 600$ GPU ASP, this is possible only if they sell at least 30%, if not more, of their GPUs within their own FE cards.

Do the maths and you ll know their real DT dGPU marketshare, it s certainly not 90%, as stated by a user in a post above this one, but more likely 65-70% assuming that they dont count laptops dGPUs within the gaming segment, otherwise not only their share in DT would be even lower but their ASP would include way more than 30% FE cards in the mix to reach the 600$ mark.

Why? IIRC Gigabyte actually has pics of 9070 & 9070 XT on their site, two editions each.
Has something happened since then?

It's not just that, if you remember their behind-the-scenes schemes, Nvidia tried to make AMD-based graphics second class citizens, pushing them out of the more premium designs. They likely give advantages to players that go Nvidia-only. I assume that was what made MSI go exclusive.

Google "GeForce Partner Program"

Gotta be interesting to see if Asus makes "ROG" GeForce RTX 5070/5070 Ti cards despite there being no ROG-branded RX 9070 (XT) - I think they have shown just the sub-tier TUF and Prime branded cards for now. If so, there may be some "GPP strikes back" sorta agreement behind it.

There wasn’t any ROG RDNA3 cards either.

Did gigabyte put the card back on coz last i remember they removed every mention of 9070 from their page like 2 days ago ?
