It is a theoretical comparison but let's just wait for reviews; just an example why in practice there is more to AMD vs Nvidia battle than specs: the number of shader units doesn't necessarily translate in more performance (they were never clocked the same so no chance for same performance): 8800gt had 112 shader units and the 4830 had 640, still they were in the same performance league.
I think that it will be exactly like last gen: AMD will win some, lose some (by very small margins) in rasterization and lose on RT, the incentive being the price IF Nvidia doesn't slash prices on the 4080 at the 999 barrier as rumored and AMD will not have the also "rumored" supply issues.
Yeah, that's why I said "assuming equal shader processor performance" - but as we know the SMs are NOT equal.

Yes, I saw - you were right to specify.
But again I think that it will be like last gen...
To tell the truth I can't wait for next week - new hardware real performance reviews are always exciting - the rumors, the naked truth, the drama, the intrigue

Shouldn't the back plate be vented or perfurated to allow the card to breathe better???
Anyway, looking forward for the review.
It is quite unusual that there isn't even a cutout in the area of the die. But I guess it makes little difference in thermal performance; all the heat generating components are on the other side after all. Though we might see some thermal pads between the backplate and PCB.

Looking at these specs I compiled, this 7900XTX should beat the crap out of 4080 in raw raster performance... assuming equal shader processor performance... although ray-tracing performance unknown... and if it sells for that price
7900 XTX vs RTX 4080
Architecture: 5nm vs 4nm
Shader Processors 12288 vs 9728
Memory 24GB G6 vs 16GB GDDR6X
Memory Bus 384-bit vs 256-bit
Memory Speed 20 Gbps vs ? Gbps
Infinity Cache 96 MB vs 64 MB (L2 cache)
Bandwidth 960 GB/s vs 716.8 GB/s
TBP 355W vs 320W
Pixel Rate ? GPixel/s vs 280.6 GPixel/s
Texture Rate ? GTexel/s vs 761.5 GTexel/s
Price €999 (assuming 1:1 with dollar) vs €1500
