Be cautious about expectations about performance compared to the 20 series. For the RTX 3080 I saw Single Precision/FP32 performance listed at 25 TFLOPs and my eyes bugged out but according to JPM, SETI.USA's resident hardware guru...
RTX 3090 $1500 24GB VRAM 10,496 cores - ? TFLOPS - 350W
RTX 3080 $700 10GB VRAM 8,704 cores - ? TFLOPS - 320W
RTX 3070 $500 10GB VRAM 5,888 cores - ? TFLOPS - 220W
I've left the TFLOPS out because I've heard the CCs are now single issue instead of double. If true, the 3090 would be just under 15 TFLOPS, if not almost 30 TFLOPS. Need to look into it further
M'kay i believe i have it figured out. What I believe they did was added a second vector float ALU pipeline that shares the same register space and execution control flow. Yes, you can say they have doubled the core count but you should also consider that they are "less capable" cores. Similar to what AMD pulled off with bulldozer cpus. And got sued over.
Basically, each core can do FP+INT at the same time, just like the 2000 series. But it can also now do FP+FP instead. However, when it does FP+INT at the same time, the total TFLOPS are cut in half. *sigh* always with the shady gimmicks
