All die sizes are within 5mm^2. The poster here has been right on some things in the past afaik, and to his credit was the first to saying 505mm^2 for Navi21, which other people have backed up. Even still though, take the following with a pich of salt.

Navi21 - 505mm^2

Navi22 - 340mm^2

Navi23 - 240mm^2

Have to wait to see reviews, but a 6800XT is looking pretty good at $650. The an extra $350 for the extra 8CU in the 6900XT is a big ask at the same frame buffer and clock speeds.

The charts comparing the 6900XT to 3090 are with Rage mode on, so OCed with likely >300W power draw. Have to see how that plays out in December.

Total demolition by AMD, I've totally been jebaited. If their numbers hold, it looks like they're going to beat Nvidia across the board, perf, perf/watt, memory etc.

Beating/matching the 3090 for $999 is much better than I expected. Only thing that's disappointing is the 6800 pricing.

$499 would have been too big of an ask, I guess? Ah well, it's super competitive and likely going to be moved a lot (guessing a OEM sweetheart with its more moderate power requirements and such, like the 2060 has been) so keeping the price up is good for margins?

Agreed, the 6800 pricing seems a bit high though you do get slightly better perf/$ to the 3070 (if AMD's charts are believed) and you still retain the full 16 GB of VRAM so better value overall. I wonder if AMD will come out with a 6700XT that will be more the direct price competitor to the 3070.

Yes 6800 pricing is clearly done to upsell people to 6800XT

6800 - 60 CU GPU with performance 10% above RTX 2080 Ti/RTX 3070, for 80$ more.

I think its a fair deal. Would be better if they would price it at 499-549$, tho...

That GPU direct memory access feature is interesting. I'd be concerned about stability on soemthing new like that. At the same time, killer feature, in some ways up there with nVidia levels of dirtiness without resorting to stupid proprietary features. Were their benchmarks presented with or without that enabled?

The 6900XT results are using rage mode and the smart access memory with zen3.
Ah lame. +$300 for a 6900XT doesn't seem remotely worth it then. They must be better binned chips to be hitting the same TBP, but I suspect enabling the same features between both and OCing to the gills will net a pretty minor dif between 6800/6900.

Nice to see that DirectStorage API feature made it into RDNA2, I was worried that it wouldn't with all the SSD focused gaming bonanza.

Unfortunately the market never rewarded AMD for big price/performance, so they only give enough value to pull those that can either go green or red.

This is all awesome and all but I hope it won't take another 6 months to see 6700 XT break cover, papa needs his low power upgrade swag.

They're probably saving some stuff for CES and want to clear out all of the RDNA1 and Polaris cards over Black Friday.

I think we'll see those cards rather early in 2021, especially once the initial console production ramp slows down and more wafers become available for other products.

Yeah, I saw that 60CU and performance and the $579 price tag and thought...hmm, missed opportunity to really kill it and price it at $499. Guess they're just trying to maximize ASP though. I would have been reeeeeal tempted at $499. Instead I'll wait to see what the 6700XT can do.
