Overclocked vs stock was a little biased on the slide though.

Yeah, I missed that initially, but again, the 3090 pulls over 25% more power than the 6900XT at stock (assuming the TBP is enforced) and the 3090 barely gains anything from overclocking, so there's room power wise for AMD to match the 3090, but we'll have to see how they stack up when the reviews drop. The main thing though is that it comes at 2/3 the price.

So out of that 54% PPW gain, looks like 35-40% is from the Infinity Cache (~19-21% PPW uplift) and the rest is from silicon level / architecture optimizations (~33-35% PPW uplift).

RDNA 2 is literally AMD's Maxwell.

Keep in mind that AMD did the smart thing and did all the bench marking with their new 5000's unreleased CPU's. This is compared to NVidia using Intel.

Hence all the AMD numbers had a 15% CPU advantage added over Nvidia.

Still very impressive and glad that I held off buying the "10GB gimped" 3080

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.

You're doing it wrong.

Realize how close the 6800 is to 6800xt is price wise, realize how much sweeter that extra performance is and justify spending not $499 but $649! 😉

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.

Its a much better deal than going from a 3080 to a 3090, which is an $800 difference. ($700 vs $1500)

If i remember correctly, since they acquired ATI, they had NEVER used an AMD CPU to test the new Radeons.
That also tells me Ryzen 5000 is killing it

If nothing else because nVidia will have been testing their own cards on Intel up until now so AMD had to have a level playing field to test their own cards.

It will be interesting to see what nVidia uses in the future - would be delicious to see them forced to use AMD Ryzen in time.

Agreed, much easier to swallow $70 than spend more on a 3090 if you were between 3080 and 3090.

Although I want to see more about AMD's ray tracing. I would go AMD but my monitor only supports gsync.

Depends if it performs better than 3070 which is priced there.

They may alter the pricing closer to availability as before - they are probably waiting to see how much like a headless chicken Jensen resembles before firming up final pricing on that SKU.
 
$999 is a great price that will make 3090 potential buyers think twice. $649 is very good price considering 6gb more memory for $50 less and equal performance. However no DLSS and weaker ray tracing performance. 6800 is pointless.

I should have read more carefully (I just read what I could on the live stream). Interesting to see that AMD played no tricks here....... even better!

Kudos to AMD for being fair with the comparisons, yeah, but it's going to be awkward now that Nvidia probably have to use AMD CPUs moving forward for all future fps claims. Knowing Nvidia, they'll just say "Unspecified CPU" or something like that in the footnotes. 😛

We can only hope. A big price drop on the 6800 when it hits retail in force - with lots of stock, right?!? - would be pretty hilarious to see.
