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

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...

9070xt was 799$ w/o tax but with shop profit so in reality msrp of ~700euro/usd.

By definition MSRP includes shop profit, though obviously there are shops who sell above MSRP.

This guy seemed to have some insight into bulgaria retail and warhouse pricing he even contacted some to get the prices.
Still 699$ is bad and doa.

$700 for a 70 class card is the dumbest god damn thing I've ever heard. Consumers have a price expectation based on naming and market position. Usually you can fudge that upward $20-30 a generation, or if inflation/mining whatever reset price expectations then you can get away with $50-75 or something.

Taking a $450 7700XT replacement card and pricing it out at $700 is essentially actively trying to kill your product, I can't see the logic in it any other way.

Ignoring all the pricing rumors (generally the most inaccurate of rumors), and since AMD revealed the name, I assumed these were 4070Ti and 4070 competitors, and figured they would be $600 and $500. Then when NVidia revealed 5070/Ti pricing, that these would have to be $550 and $450. I still think that where they will land at launch or not long after if AMD prices too high.

I can't imagine AMD was planning to charge $700 for the 9070XT, unless there is still some big upside performance surprise.

AMD's next-gen flagship UDNA Radeon GPU won't be as powerful as the GeForce RTX 5090

AMD is set to return to the high-end enthusiast GPU market with its next-gen unified UDNA architecture, however it could still fall short of the RTX 5090.

Er, wot?

Er, wot?

AMD marketing team:
"It never works out for us when our products are overhyped, what can we do about it?"
"Have we tried underhyping yet?"

 

[Mopetar]

If I were Lisa Su / Jack Hyunh (& I really wanted to sell GPUs), then I would have released RDNA 4, 6 months ago ($800 9070xt & $650 9070). Dropped prices gradually as stock moves & released FSR 4 whenever it was ready in an Incremental fashion

Customers would scream bloody hell and AMD would have to offer rebates. The only reasonable way to handle high demand and short supply on launch is an auction because that's what will happen anyway in those situations, but customers would hate that even if they pay they money to scalpers instead of the company making the GPU.

AMD marketing team:
"It never works out for us when our products are overhyped, what can we do about it?"
"Have we tried underhyping yet?"

Ah, the good old "aim low and achieve" strategy.

I'm unconvinced that AMD still wouldn't find a way to disappoint.

 

[SolidQ]

Er, wot?

It's 1k$ gpu, and also saying "won't beat 5090", but it's early leak, and possible like 5090 -10%

 

[Win2012R2]

It's 1k$ gpu, and also saying "won't beat 5090", but it's early leak, and possible like 5090 -10%

So that would be an 2026 SKU that is barely beating 4090 after 4 years on the market (at the time) to be on sale for another 2 years? This ain't gonna sell for $1k.

 

[Bryo4321]

I would imagine a 6080 would be close to a 5090, and so would the next AMD “flagship”. And you bet that 6080 will be 1k

 

[RnR_au]

This ain't gonna sell for $1k.

At 5090 -10% it will be beating a 5080. Which is a $1k today.

 

[soresu]

"Have we tried underhyping yet?"

Pretty sure that they indeed did this with Zen1.

They stated that +40% IPC over Excavator was the target and delivered >50% at launch.

Couple that with the last gen of pure CPU SKUs being 2 gens older than Excavator it delivered a pretty hefty wallop relative to what most people expected.

 

[soresu]

My guess is that the area and power impact to adding matrix units on top of existing dedicated raster silicon will result in minimal gains for UDNA in raw gfx facing ALUs.

That is unless it's a serious step up in process over what RDNA4 is using.

uh. no?

You really ought to focus on other things that make GPUs tick.

So a $749 *starting* price point was part of the plan?!

Shut the **** up Frank you're out of your element!

More likely it is a placeholder. That is max price that AMD can charge. I still don't understand the reason for this delay

$749 doesn't make sense either if AMD liked what they saw from their channels on the sales of the 7900GRE which started at $US549.

Unless I missed something from the recent AMD talks on where they see the 9070 series.

Even $US699 would seem high.

7800 XT Red Devil launched at $60 above MSRP. 7900 XT Red Devil launched at $70 above MSRP.

$700 Red Devil would mean $600-650 MSRP.

 

[beginner99]

So much for that crazy theory that AMD was delaying them to increase their prices.

Not that this one makes a whole lot of sense either. $900 for what might be 4070 Ti Super performance. Even if NVidia went into a coma, and AMD was only competing against the 40 series, I don't see that doing well.

common not even AMD marketing is that dumb to set a $900 price and now we know that things were lost in translation and msrp supposedly was $700 which with a $800 5070 ti makes a whole lot more sense.

Ye and 2 weeks ago when i said i expect taichi and nitro+ at ~800-850euro some of the guys here laughed at me and said it will be 479$....
579$ for 9070xt would make everyone and their grandma buy this card
479$ for 9070 (non-xt) would be the same. (+60% perf over 4060ti 16gb and cheaper ?)

4070ti MSRP was already $799, and 4070 was $599. The 5070ti at $749, and 5070 at $549 is not some tectonic shift - especially when the 5070 and 5070ti don't seem to bring a huge performance uplift.

If a $50 change in MSRP for the 5070ti and 5070 vs their predecessors (together with, I think, lower performance than expected) is enough to destroy AMD's launch and postpone it by two months, then AMD has some pretty bad planning with no margins.

I think 23 march is jebait.

Chiphell boss just said after azor tweet price is now under 5k yuan for oc xt and 4k+ for ref so 499$-613$ ? China has 13% tax right i dont believe it.

Can they delay again until May? I'd like a $399 card please.
