It's 203mm^2.Edit- Navi33 is rumored to be ~300m2 wasn't it?
The claim was "50% higher RT performance per CU". 7900 XTX has 16 more CUs than 6900 XT. So eh, possibly +20% on top of the 50%, eh?...Doesn't leave much room going by the lowerish numbers. Assuming ~1.5x is average ish for 7900XTX.
7900XTX ~1.5x Navi21
7900XT ~1.35x Navi21
7800XTX ~1.2x Navi21
7800XT ~1.05x Navi21
7700XTX <Navi21
Best case would seem to put the highest Navi33 somewhere between 6800 and 6800XT which is a pretty big gap, so likely closer to 6800.

One has to wonder what sort of impact the MCDs have to that equation.
Moving to the MCDs makes the GCD smaller and therefore should clock higher.
But are there power inefficiencies involved with the MCD approach?
Now I wonder about that originally rumored 8SE 15-16k shader chip.
Seeing the 355w TDP of 6SEs though... a bigger chip would definitely blow the power budget with something at least ~500w.
Ponte Vecchio, as delayed as it was, is that.
Just thought the same. If it was HW, increased perf should be better.I think the only interesting (could actually be good) thing is "new ray box sorting and traversal" - but that's probably purely a software thing enabled by memory hierarchy/usage and extra VGPRs.
What would be the number within a monolithic die - the delta is the real question.Anybody got a clue what the GCD/MCD connection is? At 5.7TB/s peak that's already 45W at 1pJ/bit.
Thanks for the correction.It's 203mm^2.
Well, everyone round here who says that 3080(ti) ray tracing performance with DLSS speed-up is good enough to play max RT in all games will be happy with 7900XTX RT with FSR 3.

If accurate to what we see in real benchmarks then its a pretty big mixed bag . of course its still $600 less in price.
1.5X 6650 XT would be around 6800 level at 1440p.Doesn't leave much room going by the lowerish numbers. Assuming ~1.5x is average ish for 7900XTX.

Kinda but that performance has been on the market for 2 years now, and it was launched at $700...Well, everyone round here who says that 3080(ti) ray tracing performance with DLSS speed-up is good enough to play max RT in all games will be happy with 7900XTX RT with FSR 3.
Yuck.
For me personally it wouldn't be enough of an increase over my 3080 to warrant a purchase. The big games I am looking forward too would be Starfield , fable , elder scrolls 6 , avowed , dead space remake and Calisto protocol. I think I can safely hold off and wait to see what the new carsd look like performance wise on those games as they come. Think my 3700 and am4 socket might get an upgrade . The 5800 3d dropped offically to $330 so could see that sub $300 for black friday and maybe we will see a good 3d cache 7x00 series and I will just jump onto that.Well, everyone round here who says that 3080(ti) ray tracing performance with DLSS speed-up is good enough to play max RT in all games will be happy with 7900XTX RT with FSR 3.

3080 was 700, it looks more like 3090ti which was 2k or 3090 which was 1.5kKinda but that performance has been on the market for 2 years now, and it was launched at $700...
The biggest elephant in the room now is how a $1000 7900XTX will compete against a $1200 4080. 355W vs 320W should also be interesting.
4080@16 is also silly versus it.Honestly those prices are great, it's a good thing Nvidia cancelled the 4080 12GB, would have looked silly against the 7900XT.
Yeah 4080 16GB probably loses to 7900XT in raster, doesn't look great value.4080@16 is also silly versus it.
Only 4090 is and was reasonable value to begin with.
By quite some margin yes.Yeah 4080 16GB probably loses to 7900XT in raster
All while still being fat margins across the stack.they should match or exceed ampere RT and obliterate in raster
