Discussion RDNA4 + CDNA3 Architectures Thread

DisEnchantment · Mar 23, 2022

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

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.

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...

SM2 not very good game, but still would add sales to 9070

This also isn't an Nvidia thread. If you are not directly comparing and contrasting to AMD as content within each post, don't write it here.

I wonder what game AMD will bundle with RDNA4, maybe Avowed?

Keller_TT · Jan 21, 2025

I agree with Kepler on this shameful backtracking.
It's now more than clear that AMD wants to get greedy and wants to come in at $600+, and be yet another DOA. So much for their reflection on B580, 7800 XT! All Jensen needs to do is adjust 4070S, TiS, 4080S pricing for those desperate 30 series upgraders, and none of the longtime NV owners or content creators are going to buy a haughty Radeon. RDNA2 upgraders might as well pick ADA too.
The GPU market is actually ready for an Intel to drive AMD to just the console space give another 2 years.

Radeon sucks in anything software or true performance differentiator vs Nvidia: media engine, CUDA, VR. So, it is where it deserves to be in mind/market share.

it's NV game. if AMD want to sell 9070, their games is Monster Hunter/Kingdome Come 2(Capcom more fits with AMD always, KC2 Vavra test their game on XTX)

gaav87 · Jan 21, 2025

And the tweet has over 300k and climbing like i said.... Soon it will have more views than amd's total CES viewership.

You often make firm statements as if you had insider info, with a rather mixed track record.

Is it a total guess, or you're a bit more confident?

sure, it has frequency bug, which prevent higher clock, will be fixed later with Navi 44 ...

Oh what? Seriously why did AMD pick the worst Microsoft game(starfield) to sponsor and left out good ones like Indy, Doom: dark ages and Avowed, I guess NV paid more.

MH:Wilds is a big game too, hopefully that’s the one. At least it’s not AC: Shadows, (Ubisoft is incompetent) like with Battlemage.

Indeed, AC Shadows would have been a "perfect fit" for RDNA4 in terms of failure to launch: initially slated for Nov. 2024, it got delayed for Feb. 2025, and then delayed again for March.

lucasworais · Jan 21, 2025

AMD made the right decision imho.

No one would buy RDNA4 if they compared it to Ada or without knowing how Blackwell performs. Remember, regular gamers are always much more prone to buy Nvidia.

RDNA4 it’s expected to go on sale on march but the announcement will probably be right after 5070 reviews drop. People who bought the 5070 series will still be able to return it after seeing the supposed better performance of the 9070 series.

I agree with Adroc, doesn’t make sense to announce at the same time as the 5090/80, they would be completely overshadowed.

As for retailers and distributors, I don’t think they are caring that much about holding the stock, as long as they can sell it for a higher price and thus having better margins. AMD can also pay them rebates for that.

Since AMD expected to sell RDNA4 at lower prices/margins, they are probably going to be ok with lower margins at beginning and then having it higher after a few months.

And besides, reviewers would compare them to 5000 cards anyway. There is no excuse.

They need Blackwell reviews to showcase how underwhelming the parts really are before they drop their stuff.

Yeah I think that is the only reason that makes sense. They want reviewer to compare 9070 (XT) directly to 5000-series. the only way to do that is to wait for 5000 series reviews and launch after that. Then in every AMD 9000 series review people look at, the 5000 series would look pathetic.

leoneazzurro · Jan 21, 2025

It can be disappointing from a user's standpoint, from a company perspective it makes sense after they gave up on the halo part because they thought it was not competitive and as such they would have lost hundreds of millions in developing an (in their thinking) useless big die. They want to make the most out of the 9070 in the current conditions, and as such they must deliver a part that is very competitive (aka, better performance/price ratio). If they can better refine the drivers and FSR 4, then someone can think it may be worth the wait. Not the best way to satisfy many users, for sure.

They should have made it beyond competition - that's what chiplets were for! And if they want to give up then they should find some other job.

Apparently Starfield needed optimisations and AMD was called to help, which they apparently did.

I think I said that giving up high end was a questionable decision, it may make some sense if you expect to not sell high end stuff because people will go for Nvidia anyway. Also, it seems chiplets for GPUs are not ready yet, at least not in the sense of having something like Ryzen-esque (performing and cheap to build). MI300-like parts costs are not consumer-oriented for sure. Let's hope for the future.

ToTTenTranz · Jan 21, 2025

The delay makes no sense. They have the price and performance estimates for the 5070 series already, and cards in the distribution channels and stores.

But now they decided to wait until the actual 5070 cards are out there with reviews published, even if it means losing 3 months' worth of a blue ocean in that performance point with a fresh product.
Not even the "Nvidia -10%" tactic can be used as justification, here.

What this projects to the general public is the notion that AMD is constantly terrified of whatever Nvidia may or may not do, that they have almost no faith in their own product but must still focus on maximizing how many pennies they can per GPU sold. They're showing they can't follow any path other than having the cake and eat it too.

It projects a notion of immense weakness and lack of commitment, that they might drop the whole business if the risk score goes 0.1% above the previously planned. And that people should really look the other way if they want to feel safe about their purchase.

And the sad part is that neither of this will matter in the end. Reviewers will, for the most part, publish select benchmark comparisons with multi-frame generation on so the 9070 cards will be completely overwhelmed, even if in regular conditions they surpass the 5070 Ti by 15% at the same price point.

If both cards are out there for them to choose, people will buy Nvidia because those cards can run multi-framegen, plus those small LLMs for AI hobbies that Nvidia is offering, plus predictably decent VR performance, etc.

It was always going to be a lose game because AMD's market and mindshare is down the toilet, and the only way to recover some of that was to provide a product with much better perf/$ that came out earlier on top of it.
Instead, it looks like AMD chose to lose more so they can squeeze a couple extra dollars per GPU sold.

Is AMD's only strategy just Nvidia - 50 dollars?

blckgrffn · Jan 21, 2025

I think a funny situation that could arise is the Switch 2 drops and all the news - and hundreds of dollars of gamer budgets - gets instantly reallocated to it just as both the 5070 and 9070 try to leave the gates.

That would be a fitting moment, I think. There is more than just one way for gamers to spend their money. Time kills all deals as my real estate buddies like to say.

IMHO, setting the “record” that the 9070 cards are “the better buy for gamers” against the 5070/5070ti (maybe) for a year plus until there is a Super refresh with more vram probably being the big draw - and one that probably won’t move the performance bar much - is probably the right move if they want to “win” at anything.

That said if it (9070 family) really did well against the 4070 and 4070 Super and in reviews in a couple months still did great against the 5070/5070ti then… idk. Maybe it’s not a huge difference. I guess what it does is lock in nvidias MSRP that everyone will remember forever vs a surprise cut that could happen if Nvidia thought their 5700 launch needed more juice vs the recently launched 9070s.

Whatever. It seems to be making it all harder than necessary and Nvidia can always flex the 5800 down a bit to really “win” any time they want.

Care to name another strategy that doesn't lose money for Radeon? Market share chasing didn't work out for long. They had their best quarters in history with Nvidia minus $50 card, the 6800 XT.

The problem is they need a good and big card to do anything else and they don't have it.

Those were crypto-craze quarters, though. It had little to nothing to do with gaming performance.

Being 2nd (and far behind) in two horse race means they have to accept less than 50% gross margins and make up for it in volume, this could still be RDNA4

Is Nvidia -$100 the plan then? Still have to wait and do the same thing.
