Discussion RDNA 5 / UDNA (CDNA Next) speculation

[luro]

They intend to drop support of rdna2 while those GPUs still on shelf and all the rdna lines that should support ROCm still has serious issues running it

It's actually a lot worse than that.

AMD dropped support for RDNA3/3.5 which is an architecture coming in future products like Gorgon Halo.

At the moment, there's hardly any reason to trust AMD's GPU support at all.
Buyers of recent RDNA4 GPUs are likely to regret their decision in a couple of years when RDNA5 is out there.

Their latest driver literaly has a bunch of fixes for RNDA2 and RDNA3. I dont know how this is not supporting.

I don't know about ROCm, but at least the driver thing AMD somewhat backtracked from was "only" about RDNA1+2, and more about Day 1 support + optimizations for new games, rather than total droppage.

RDNA3 is in "maintenance mode" just as much as RDNA1+2. FSR4 and Redstone were exclusive to RDNA4 and there's zero sign of this changing.

Yes, fixes means "maintenance mode". Support should mean game optimization and support for newly launched software features.

It's not worse at all.
NV just doesn't talk about it.

Nvidia is definitely supporting it's last gen better than AMD. Not just from a features standpoint but optimizing games too.

Grafikkarten-Rangliste 2026: GPUs im Vergleich

Welche Grafikkarte kaufen? Für Februar 2026 gibt es Empfehlungen mit Nvidia GeForce RTX 5000, AMD Radeon RX 9000 und Intel Arc.

Nvidia has been gaining ground on AMD last gen vs last gen.

The RTX 4080 is now faster than a 7900xtx and the gap between a 7900 xtx vs 4090 is nearly 39. percent(where it used to be 29%). The 4070 regular is now beating a 7800xt where it previously lost.

The RX 7600 is 31% slower than a rtx 3060 ti where it used to be 17% slower.

With new releases aside from rare exceptions like call of duty, AMD cards tend to underperform in regards to their last gen while Nvidia cards perform at normal expectations. The 6700 Xt performance is underwhelming too. Its slower than a rtx 3060 ti even with 8gb of vram. Bring in AMD ultra underwhelming support and launch of redstone, lack of support of FSR4 on anything aside from RDNA 4 and it just confirms what you already know. AMD does not care about client GPU.

The test suite changed. Even something as simple as using a different, faster CPU will favor Nvidia's CPU heavy drivers.

And other test suites disagree with that assessment.

Go spread your multivariable schlockbenches/FUD in another (non-vendor) thread. RDNA3.x isn't in maintenance mode despite not having all features. Much like Ampere isn't in maintenance mode despite not having MFG.

Yes, fixes means "maintenance mode". Support should mean game optimization and support for newly launched software features.

It's unrealistic to expect any of the following:
1) new software features like FSR4 that rely on new hardware added
2) doing anything other than maintenance mode for product lined that EOL-ed
3) doing game optimisation in drivers - drivers should have never done that, it's the job for devs to optimise their games that they sell: driver should just be driver that complies with the spec and does it as fast as possible.

If changing the test suite alter the results in favor of Nvidia, it proves my point correct. That is AMD results with older games or games released during its retail life show better results as a result of AMD optimizing for that generation. If AMD last gen is losing ground with new games vs Lovelace and RDNA4, it means AMD is not optimizing for newly released for its last gen.

E.g look at Anno 117 results below. These results do not include ray tracing. Lovelace performs where it should. RDNA 3 on the other hand does not and RDNA 4 towers over it.



Same thing but to a lesser extent happens in Battlefield 6.



Looking at the 7900xtx and 7800xt results compared to the the 9700xt. Now compared Blackwell vs Lovelace. Nvidia cards are performing where they should while AMD's last gen is not.

Adding new games to test results and last gens card performing well in them show if a vendor is optimizing for these new games for their last gen(i.e optimizing rather than just bare minimum support). AMD fine wine was derived from this. Remember this used to be the case of the 7970 or RX 580 for example. These cards aged much better than the gtx 680 or gtx 1080.

It is not just computerbase.de that is show this regression, it is techpowerup too.

Sapphire Radeon RX 9060 XT Pulse OC 16 GB Review - An Excellent Choice

The Sapphire Radeon RX 9060 XT 16 GB sells close to MSRP, yet it features a factory overclock and higher power limit. In our testing, its cooler remained whisper-quiet even at full load. Interestingly, this model uses Samsung memory, whereas all other cards we've tested so far use Hynix.

Note these results also are at 4k(atleast with the rtx 4080, 4090 vs 7900xtx) thus the CPU affect should be negligible. AMD should be gaining ground even more than before at 4k because of their vram advantage. If they are not and are losing ground, it means AMD is just doing the bare minimum to ensure compatibility and stability. Nvidia rtx 4070 should not be gaining ground at 4k with a 12gb vram buffer vs a 7800xt.

No, it doesn't. Your multivariable tests show nothing of the sort.

You can easily look at AMD commits to llvm forks and linux in the last year to show it isn't in maintenance mode. They had made changes to their compilers that we can see in public for older architectures. Your worthless theory crafting ignoring architectural differences, testing setup variation and game selection is falsified easily by looking at real, shipping code which improves performance on e.g. gfx11.
