It all depends on the configuration of the chips -- and note the use of "up to" and less than signs. There are at least plausible leaks of a 124 SM Ampere chip. As I note in the text, that's not a "good" number for the maximum configuration, because GPCs usually all have the same number of SMs. So 16 GPCs with 8 SMs each would work, or 12 GPCs with 10 SMs each (which is fine for the 118 SM leak but doesn't cover the 124 SM leak).How is it possible that the 3080Ti has double the GFLOPS of 3080? The 2080Ti is not even close to double the speed of 2080, its only 30% faster in games and has 10.07GFLOPS.
Also the 2080Ti is 14.2GFLOPS, I don't believe that the 3080Ti is more than double at 28.7GFLOPS at 102%.
Even if game performance is lower than GFLOPS this is still unbelievable.
Thanks for the elaborate answer, that makes more sense now.It all depends on the configuration of the chips -- and note the use of "up to" and less than signs.

What will the chips actually have enabled, though? My guess is around 112 SMs on an RTX 3080 Ti would make sense. If we use that figure, and the same clockspeed, TFLOPS drops to 25.1. So, that's part one of the story.
The second part is the rumored GA103. I put down 64 SMs as the top configuration, but 72 or even 80 SMs is entirely possible, as noted in the text. So I probably undershot on the GA103 estimate and overshot on the GA100 estimate -- or RTX 3080 and RTX 3080 Ti, if you prefer. I also gave GA103 a higher potential clockspeed advantage. If RTX 3080 ends up with somewhere between 72-80 SMs instead of 64 SMs, performance ends up at 18.4-20.5 TFLOPS.
Realistically, then, RTX 3080 Ti will probably be in the 20-25 TFLOPS range (for FP32). RTX 3080 will end up closer to 14-16 TFLOPS. Or Nvidia does something completely unexpected and the theoretical TFLOPS values end up much lower but real-world performance (ie, the utilization of the available compute) goes up.
Actually, having thought on it a bit more, I think GA103 will probably have more than 64 SMs available. RTX 3080 could still go with 64 SMs enabled, but if Nvidia can do a 128 SM chip, the second tier will probably be much higher than 64. I've adjusted the tables and text slightly to reflect this.
FYI SM --> Streaming MultiprocessorNvidia's upcoming Ampere architecture could bring a massive boost in performance and capabilities. Here's what we know and what we expect.
Nvidia RTX 3080 and Ampere: Everything We Know : Read more
What else are people doing now that most are staying at home? You need articles to fill the "new" queue for the greater idle time people have now. Speculative articles are easy choices to keep something "new" in the queue."As with Big Navi, the best advice right now is to wait and see what actually materializes."
Took a while to get there but I agree. Way to much rumor mill stuff going on about graphics cards and very little seems likely to be factual. I'll just wait until AMD and Nvidia both release their next cards.
Plus we didn't actually have a central hub for all the Ampere (and Big Navi) rumors, which is a good thing to put together for any website that covers GPUs. There's not a lot of concrete information right now, but we'll keep this updated as new stuff comes out, and eventually it will morph into our Everything We Know article with final architectural details when the parts get announced.What else are people doing now that most are staying at home?

Same here with Canadian dollar, my Asus 2080 Ti cost 2200$ with taxes now but I got it used 6 months ago for 1500$CA from ebay.An Arm and a leg wont cut it. With a 2080 Ti easily costing 60% to 80% AUD more than the previous generations, I expect this will be at least 100% - 120% more than the GTX 1080 Ti. About 2 months rent ought to cover it. Actually it could be more as the AUD is plummeting to 50c USD, so that might be A150% or more. I don't think many Australians will get to run one of these new cards.
Consoles use one pool of RAM for system and video memory, so the GPU will never be able to use all of the RAM on the spec sheet.Shouldn't 8-16GB be the new base line for VRAM? It's not just a technical need but also for marketing reason. Nvidia used 4-8GB memory for the last console gen and bump the baseline to 6GB when XboxPro came out with 12GB. given the XboxSeX and PS5 specs I would think the 3060-3070-3080 spec would be 8GB-12GB-16GB. It doesn't look good for the top 3080 to have less memory than a console.
Considering Turing at least has partial HDMI 2.1 support (it can do VRR with HDMI 2.0), I strongly anticipate HDMI 2.1 in Ampere. Nothing is certain of course, but I'd be very surprised if HDMI 2.1 and DP 2.0 aren't included.Depends whether or not 3xxx series comes with HDMI 2.1 - If not that will be a dealbreaker for a lot of people
