I'm not going to pretend that I understand half the things said in that article. But anyway:

I was going to ask if the site is credible, but given how new it appears to be, the answer is no. Maybe if we knew how's behind it, things would change but, for now, I'd take it with huge amounts of salt.

That said, the Infinity Cache sizes are quite interesting (and easier to understand). Looks like, while it does work and help in certain scenarios, fast access to VRAM is still necessary, hence why they would have reduced the IC but bumped the memory bus width compared to Navi 2x. This, if true, could help the cards perform better at higher resolutions, where it was obvious that the memory configuration hindered their real performance, something we all saw with the xx50cards, that with just slightly better memory, offered better performance.

In any case, I'd wait for other sources to start guessing its performance.

Yea that's the main take away. I probably should have waited for the videocardz article as they make things a lot cleaner.

Essentially if we look at the rumoured 4090 vs 7900XT.

4090 16384 Cuda Cores vs 7900XT 12288 Stream Processors
4090 72MB of L2 cache vs 7900XT 96MB of L3 cache
4090 24 Gbps memory bandwidth vs 7900XT 18 Gbps memory bandwidth
Lovelace TSMC N4 vs RDNA 3 TSMC 5nm + 6nm

Now obviously, none of specs above that I listed are any indicators of real world performance. But I think it's going to play out as 4090 > 7900XT > 4080 ~ 7800XT in Raster.

Moore's Law Is Dead has pretty much agreed on the specs apart from the Navi 32 where he still has 8092 Stream Processors instead of 7680. Both could be correct if the 7700XT/7800XT (I expect the Navi 32 to be for the 7700 and 7600 series and Navi 31 being used for both 7900 and 7800 series, with Navi 33 being for 7500XT and below) comes out with 7680 and then later down the road a version with 8092 would appear.
