It looks like the 'real' /affordable RDNA3 + next gen NV desktop launch won't launch until September. Thoughts?

Interesting rumours.

It looks like there's nothing officially announced yet but more Navi33 GPUs (like the 7600 and 7600XT), this time for desktop, which isn't particularly exciting because they are limited to 32 CUs and use the 6nm fab. process, so 1080p tier.

RDNA2 workstation Navi21 GPUs didn't launch until June 2021 (RDNA2 desktop launched in October 2020):

RDNA3 workstation Navi31 GPUs (e.g. W7800 with 70 compute units) are supposed to be released this quarter, so very likely in June 2023.

My guess is that we could get a desktop equivalent e.g. RX 7800 XT in Q3 2023.

But Navi32 remains a mystery.

To me, it would be logical that the 7700 and 7700XT would be the only Navi32 cards, considering that Navi22 was used for the RX 6700 and XT.

But there still seems to be quite a lot of RX 6700 and 6700 XTs in stock (some models), which suggests a delay to Navi32.

The obvious next step for AMD would be to release Navi32 mobile chips, as there's definitely a gap in the market there.

No reason to think that the RX 7700 XT won't be a Navi32 card.

Should be decent if that's the case.

I was thinking before that the RX 7700 - RX 7800 XT are likely to be Navi32, and would replace Navi21 cards.

It's difficult to know for the RX 7800 XT though. Yields are not good for Navi31, so I'd imagine it's more likely to be Navi32.

I don't know if any of that info is set in stone, it might just be placeholder stuff / outdated info.

We need more info specifically on Navi32 to clear things up really.

It's strange how AMD has said nothing about Navi32 mobile GPUs yet.
 
I think AMD's main problem is still that they can't produce enough Navi31 /top tier GPUs.

I'd guess that they didn't invest enough to begin with, because they weren't sure there would still be enough demand for high end GPUs in 2023.

Always easier to produce less and sell at a higher margin...

In the meantime, I'm sure they'll make lots of money selling Navi33 GPUs to laptop manufacturers...

AMD is still mostly a CPU focused company, they've been focusing on the X3D launch recently.

Producing as many GPUs as Nvidia is the only way they can provide real competition and Nvidia.

That doesn't mean they need to copy Nvidia and make a Navi 33 based RX7700XT.

I guess we'll see. I don't think it makes any sense, because it would be slower than a RX 6700 XT or RX 6750 XT, which both sold quite well.

No one would buy it, unless priced cheaper than the last gen.

Also, 8GB of VRAM? Press X to doubt :D

DRAM is supposed to be getting cheaper in 2023.

It would be better to delay further, than release that trash.

Might as well not release a RX 7700 XT at all (keep producing RX 6700 series), which is probably what AMD thinks too.

Wait for credible news about Navi32 GPUs, particularly mobile versions.

Or they could do so something weird, like make the RX 7700 a Navi33 GPU (to produce in bulk), and the XT / XTX a Navi 22 GPU and release it a bit later.

But the VRAM amounts look incorrect, considering the 12GB of the last gen.

The latest thing AMD has released is 4nm low power Phoenix GPUs (mobile):
en.wikipedia.org

RDNA 3 - Wikipedia

en.wikipedia.org en.wikipedia.org

I wonder if AMD is going to use TSMC's 4nm process for any desktop graphics cards?

The fact that they are already using 4nm for some RDNA3 products, suggests that they are unlikely to use 4nm for RDNA4 (3nm seems more likely).

No desktop Phoenix APUs have been released yet either, maybe they will come next?

Oh well, at least if the 7600 XT is 32 CUs, it won't be any worse than a 6600 XT:

AMD Radeon RX 6600 XT Specs

AMD Navi 23, 2589 MHz, 2048 Cores, 128 TMUs, 64 ROPs, 8192 MB GDDR6, 2000 MHz, 128 bit
www.techpowerup.com www.techpowerup.com

We know the 7600 is an 8GB card, so it looks likely.

It terms of the performance, the FP32 processing power is about 2x that of the RX 6600 XT:

AMD Radeon RX 7600 Specs

AMD Navi 33, 2655 MHz, 2048 Cores, 128 TMUs, 64 ROPs, 8192 MB GDDR6, 2250 MHz, 128 bit

Basically, they can get a decent boost compared to Navi23, because the RDNA3 architecture is faster.

The higher floating point processing power seems legit to me.

There's quite a big performance boost in the Navi33 mobile GPUs also:

87 FPS in Cyberpunk 2077 at 1080p, not bad at all.

So, it's 20% or more boost from RDNA2>RDNA3 at the same CU count.

Edit - It's not a perfect comparison though, because the 6700S is a 28 CU GPU...

So, probably more like 15-20%.

So the RX 7700 XT and RX 7800 XT should be about 20% faster than the last gen.

I wouldn't say we know what 7600 actually is.

We know N33 is 128 bit which mean 8GB or 16GB and it seems logical that N33 will be used in the 7600

I doubt they would bother with more than 8GB of VRAM, it seems overkill on a N33 GPU. It's a 1080p class GPU (according to the AMD slides for N33 mobile).

16GB will be reserved for N32 graphics cards.

20GB and above for N31.

I think you would have seen 16GB of VRAM on the N33 mobile GPUs if that was the plan.

12/16GB is a big selling point for N22 and N32 cards.

I bet the 7700 is gonna be reasonably priced tbf.
