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

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...

New cards always tend to have worse bang for buck ratio compared to outgoing discounted last-gen parts (hunting those at the time when n+1 generation lands has always been a good point for frugal GPU purchases, it's like with those price-slashed Ryzen 7000 processors). Completely normal.

It wasn't always like this, at all.

New generation cards would usually wipe the floor with the older one in perf/$. It would be after the new gens being on shelves that the older generation would lower a lot to clean all the stock.

It would be a marketing win to have atleast 9070 below $500

& it won't look good marketing wise to exceed the street price of 7900xt ($650) for a 70 class card (9070xt)

It had better be worthwhile to chase that 4% crowd.

It had better be worthwhile to chase that 4% crowd.

reality will be it will still yell out, at least in the US, at $799 IF performance rumors are true (~7900xtx. ~4080) and the actual final street price is $799. what else are you going to buy? $1000 for a 7900xtx or 5070 Ti?, $1500 for a 5080? it would sadly so be the best performance/$ and available to some extent.

I hate it as well as I was in the market but $799 is simply to high of a price.

We'll see.

Um amd at 14.65% total mss and at 21% card sales.
Lets not keep the momentum 9070xt 749$

올해 라데온 그래픽카드, 뭔가 심상치가 않다?[차트뉴스]

2025년 들어 그래픽카드 시장은 새로운 세대의 칩셋 출시로 뜨겁게 달아오르고 있다. 엔비디아 지포스 RTX 50 시리즈는 스펙상 강력한 성능이 기대되었지만, 막상 뚜껑을 열어보니 DLSS 기반의 프레임 생성에만 집중된 모습이라 유저들의 실망감이 커졌다. 더불어 예상을 뛰어넘는 높은 출시 가격으로 논란의 중심에 서 있다. 이러한 여파 때문인지 AMD 라데온 그래픽카드의 판매량이 눈에 띄게 증가하고 있으며, 그동안 지포스의 보조 역할에 머물렀던 라데온이 2025년에는 새로운 변화를 이끌어낼 수 있을지 주목된다. 다나와 리서치...

Hilarious they went from 9% mss to 14% in january to 20.8% in february ?!?!?

With basically no NV product available in DIY other than the 4060, I'm not surprised.

 

[SolidQ]

I wonder what if 9070XT is way faster in SH2(and similar games) than XTX?
Every time i see SH2 is pretty bad running for AMD cards

 

[PJVol]

I wonder what if 9070XT is way faster in SH2(and similar games) than XTX?

You mean in similar very lengthy interactive cutscenes which are by some misunderstanding called games? )

 

[SolidQ]

mistakenly called games?

you can still play

 

[PJVol]

you can still play

Quite a creative interpretation of the concept of a game )

Status of the competition:

• good at $749
• not worth the money at $849
• a bad joke at $899 and above

Well, N48 won’t beat 5070ti and it wouldn’t touch a 5080 with GDDR7 or whatever. The hype got out of hand again. RDNA4 might still be good from a PPA standpoint if the smaller die size estimates are accurate.

If it ties in raster and makes up at least half the gap in RT to the 5070 Ti it'll probably sell some. At least looking at 5070 Ti pricing in Canada (CA$1250-1350) it's going to be about $200 cheaper and might be available. It won't be flying off the shelves at $1000-$1100 if that's all it brings though.

 

[adroc_thurston]

N48 won’t beat 5070ti

?

and it wouldn’t touch a 5080 with GDDR7 or whatever

?

 

[gdansk]

Well it won't work at $700 MSFP (manufacturer suggested fictional price). AMD better get low.

 

[adroc_thurston]

AMD better get low.

It's $749.

 

[gdansk]

It's $749.

They can't spend $500,000 to copy fictional MSRP technology? It will torpedo their product line for the 2nd time in a row.

 

[marees]

Well it won't work at $700 MSFP (manufacturer suggested fictional price). AMD better get low.

The MSFP needs to be $625 or below for the 9070xt

 

[adroc_thurston]

The MSFP needs to be $625 or below for the 9070xt

Why would it need to be anything but $749.

They can't spend $500,000 to copy fictional MSRP technology

They don't have to. 749 it is.

 

[marees]

Why would it need to be anything but $749.

Because it is MS(Fake)P

 

[ToTTenTranz]

Why would it need to be anything but $749.

Let's talk sales numbers in 3 months.

 

[adroc_thurston]

Because it is MS(Fake)P

What if it's real.

Let's talk sales numbers in 3 months.

It will sell 3 units in total either way.
No halo.

 

[ToTTenTranz]

It will sell 3 units in total either way.
No halo.

Then at least we agree it's a failed graphics card at that price.

 

[gdansk]

What if it's real.

Then they still shot themselves in the foot because it will be compared to imagination land pricing. Like a $800 RTX 5080.

 

[exquisitechar]

?

5070ti basically appears to ~equal the 7900XTX, so yeah.
