AMD’s RDNA 3 GPUs might not be quite as powerful as previously rumored

AMD’s next-gen flagship graphics card may not be as powerful as previously claimed, and the same goes for GPUs at a lower level (i.e. Navi 32) , at least if the last word of the vine is correct.

This new rumor comes from well-known leaker Greymon55, who posted a (purported) revised core count for AMD’s incoming RDNA 3 graphics cards.

The theory, then, is that AMD has reduced the number of cores it’s aiming for on both the Navi 31 (flagship) and Navi 32 GPUs, with Navi 33 remaining the same (Greymon55 has floated the number provided here to Navi 33 in the past). Obviously, take all of this with a healthy skeptical outlook, as with all hardware-related speculation.

So how much have those base numbers gone down? For Navi 31, which is expected to be the RX 7900 XT, the previously announced 15,360 core count has been revised down to 12,288, while Navi 32 (RX 7800 or possibly 7700) has been reduced from 10,240 to 8 192. The mid-range Navi 33 chip remains as previously thought, still pegged at 4,096 cores.


Analysis: Nvidia now seems more likely to win the raw performance battle?

As VideoCardz, who spotted this, points out, the recent claim that the RDNA 3 flagship could weigh in with 92 TFLOPS in terms of raw performance might be out of line given this new reveal – or maybe there is. has something about the GPU that we don’t know yet. Or this rumor could also be false, of course.

We could then be looking at more like 73 TFLOPS (and to be fair, that would line up more with some of the leaks we’ve heard in the past anyway), with Navi 31 seemingly ready to sync with a nice 3GHz monster (in the past, figures more around 2.5 GHz have been theorized – though remember that the incoming refresh of the current-gen 6950 XT should already exceed 2.5 GHz, straight out of the box).

So the general mood of the signal here – that AMD’s next-gen GPUs may not be bristling with as many cores as we thought – might be seen as somewhat underwhelming, but we have to be cautious. Be careful with all that rumor mill pre-release noise.

Still, that might be something to worry about in light of what we just heard about Nvidia’s incoming RTX 4000 models that Lovelace might deliver even more of a performance boost than expected, and that it’s no longer just a refresh of Ampere – there will be bigger changes to the architecture.

If this is true, then Nvidia could do better than expected in the battle for raw performance, although this may come at a cost in terms of power consumption – Team Green’s next-gen GPUs are expected to make huge demands. at the PSU, while AMD’s RDNA 3 card should be much more efficient.

Especially at the high end, the prospect of power consumption forcing gamers to upgrade their PSU is a real concern for Lovelace – as is the possibility that AMD could have its mid-range RX 7000 models end-of-the-line first, whereas Nvidia might only have its flagship RTX 4090 to start with (not the graphics card anyone with a normal-sized bank balance will be looking at).

Obviously there are a lot of different and complex variables to consider in terms of the success of these next-gen GPUs – plus you can also add to the mix the unknown of exactly what impact Intel will have when launching desktop Arc graphics cards. , supposedly next month.
