The future of RDNA on Desktop.

[2901BitSlice]

Now that AMD's RX9070 Series GPUs have been Announced and will be Released for Sales starting this Thursday I have been read rumors that this is it for RDNA on Desktop. The next Revision of RDNA, RDNA 5, will be for Mobile and Gaming Consoles. The next node for Desktop GPUs will be UDNA. If RDNA is successful beyond all expectations could AMD Leadership be pursuaded to do one more iteration of RDNA, call it RDNA4+ that is configured with 20GB of DDR7. The current Boards uses GDDR6. Call the new card the 9070 XTX and do a similar upgrade on the current 9070 vanilla with 20GB of GDDR7.

As you can tell UDNA1 doesn't give me the warm and fuzzys. And it looks to me AMD has a Winner in the 9070 Series.

Any thoughts ?

RDNA 4 is the last RDNA architecture. The next mainstream desktop one is UDNA. They decided so because it costs AMD too much to develop two architectures simultaneously, not to mention the sporadic ROCm support on (cheaper) gaming cards drivers away sales from people who need compute, but don't have the need and/or cash for an enterprise card, and have to choose Nvidia for CUDA. As for whether it's good for gaming or not, we'll see. Personally, I'm due for an upgrade anyway, so I'll just get a 9070 XT and call it quits for a good 2-3 gens.

We might see higher VRAM variants but I don't see AMD spending any time on significant revisions for future RDNA cards past the shortly to be released series.

That would just detract resources from UDNA and that is AMD's number one priority right now. Keep in mind that UDNA will now be including all their gaming, compute, and AI improvements from now on. The name might not sound exciting to gamers but it should be given that some of the benefits to compute and AI have already been integrated into RDNA4.

AMD could have easily given it 6144 units and GDDR7 with just a 16% larger die area of 420 mm2.

Nah we're not allowed to have high end cards anymore.

They could have, but a larger chip comes with higher manufacturing costs, which translates into a higher price. People are looking for Nvidia at that price point, so it would have been a futile investment.

At least not from AMD ;^)

UDNA is the next arch after RDNA

No, it's not that simple. If the Navi 48's memory controller wasn't designed to handle G6X or G7 from the get go, upgrading the memory won't be a trivial matter. They could at most extend memory capacity by adopting 32 Gbit ICs. 16 GB at 256-bit likely means 8 16 Gbit ICs installed. But higher density memory chips or clamshell tend to have certain drawbacks like inferior timings or heat dissipation, power consumption in the case of a clamshell configuration.

This gen RDNA doesn't need GDDR7 to compete. Straight up.

I wouldn't worry about the name. Just think of 9070xt as a low-end UDNA chip you're getting early.

As I've said before, it's likely RDNA4 is competing with the next-gen low-end Rubin (128-bit) and *maybe* (if they release a high-clocked 16/32GB model) a cut-down slightly higher-end chip (7680sp on 3nm).

The point is 1080pRT mins and 1440pRT (sometimes upscaled) averages, and is likely how the XT/XTX will be divided. Again, I reference Wukong at 1080p and 1440p. Or Spider-man 2 in 1080p or 1440p.

It's just bringing the new market segmentation to you a little early because right now some games will be okay-ish at 1440p, but long-term it'll be a 1080p card. 1440p will be the 18GB market on 3nm.

This might piss some people off long-term, but remember that nVIDIA still thinks that's worth $750-1000. Again, this is why this chip should be cheap and they shouldn't sell it as 1440p/4k *really*...but whatever.

We're in a transitional point between pure raster and standardization of RT so I guess they will.

Beyond that, I wouldn't worry.

AMD could have easily given it 6144 units and GDDR7 with just a 16% larger die area of 420 mm2.

You mean ~12288sp (essentially 7900xtx but with RT/FSR improvements and high clock)? That's next-gen...I think they purposely avoided it this gen given it they'd have to sell it for >$1000.
When nVIDIA cut the costs of 4080, I think they decided it wasn't worth pursuing on 4nm. Next-gen AMD/nVIDIA are going to fight that battle HARD (~4090 performance), as lots of people want that.

If you mean 6144sp, like 5070, that too (approx configuration; 3x 1920sp or 2048sp chiplets) is probably next-gen. Same with nVIDIA. It will likely replace 9070 xt almost directly in performance on 128-bit/GDDR7.
