Ampere Tflops are weird. Counted the old way, say a 3080 would be 21.6Tflops, and this is how we'd get back to the traditional situation where for a given performance Nvidia has less flops on paper than AMD. Nvidia reversed that rule by way of Ampere. So don't get too quick to compare them basically.
TL;DR 1 Ampere TF = 0.72 Turing TF, or 30TF (Ampere) = 21.6TF (Turing) Reddit Q&A To accomplish this goal, the Ampere SM includes new datapath designs for FP32 and INT32 operations. One datapath in each partition consists of 16 FP32 CUDA Cores capable of executing 16 FP32 operations per clock...

Also ignore any CGI artists that tell you flops are the only relevant metric in all of graphics pipelines.
