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

*pic*

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.

Hey, if you're going to compare different cards and architectures, at least make it full by bringing the "old" parts

4090 16384 Cuda Cores vs 3090 10496 Cuda Cores  =>  a 56% increase

7900XT 12288 Stream Processors vs 6900XT 5120 Stream Processors  => a 140% increase (!)

By that alone, the jump AMD is going to achieve should put it well ahead. Right? ... Oh, if only things were that easy.

*Edit* Seriously, tho, if AMD manages to pull such ridiculous increase in Stream Processors AND they aren't left unused by some ridiculous bottlenecks like with Vega, it will be nothing shorts of impressive.
