What was the Specs of the PC that they were testing with? With new Ryzen 5000 CPU, you can OC the RAM to 6536 Mhz. Paired with Smart Access Memory would be interesting to see some bench marks.
I put all of the slides at the end, the full details are in the last few slides. It's Ryzen 9 5900X, basically. We're not entirely sure how much that factors into AMD's performance, but at 4K it might make a 5% difference.
I have to admit, I thought they were going to have cards that definitely gave the RTX 3070 and 3080 a run for their money, performance-wise, match or slightly do better than Nvidia on power/performance, and definitely offer a better price/performance value.
It's a mixed bag on the efficiency aspect, and on the price/performance, depending on which card.
I absolutely did NOT expect them to go gunning for the 3090. I really thought the top Big Navi would be the 3080 competitor, and am pleasantly surprised that they did so.
Can't wait to see the results when Jarred gets a hold of these cards.
Early this month, I was basically thinking 6900 XT was going to be what AMD is effectively showing for the RX 6800 XT. Clocks are higher than expected, and the Infinity Cache apparently is helping out a lot. Wouldn't it be sort of funny if slapping a huge L3 cache onto Navi 1x (plus ray tracing) is all it took for AMD to match Ampere? The RX 6800 XT having 72 CUs actually makes perfect sense, though -- fully enabled Navi 21 parts aren't going to be nearly as common as completely functional chips. I wish AMD or TSMC would reveal yields, but those are closely guarded secrets these days.
Anyway, I'm glad that there's a reasonable part between the 60 CU and 80 CU variants. Rumors only showed up indicating such a part more recently, and I got tired of trying to chase down and verify such things. Happy to see I was wrong and that AMD really did show the second tier GPU, but again it was nearly the same performance as the top tier GPU.
Also, AMD is definitely skewing charts in their favor on RX 6900 XT by enabling the one-touch Rage Mode overclocking, plus Smart Memory Access. I don't mind the latter so much -- it's the benefit of running AMD on AMD, basically -- but I do wonder if there are ways other platforms could enable larger apertures, and why it hasn't been done up until now.
Ray tracing and DLSS are still going to be important battlegrounds, especially with the next-gen consoles supporting RT. AMD may have an advantage, since it provides the console GPUs. Then again, 52 CUs is a decent step down from RX 6800, and the 36 CU PS5 and 20 CU Xbox Series S won't be anywhere close to Navi 21 performance. So, console games probably won't push RT as much as PC games, since we have PC GPUs that are already potentially 50% faster than the best console hardware. Anyway, exciting times!
