Hi there,

Hi James,
I can't remember a T4 hitting 2500 GHz-d/d. And while that A100 has a TDP of 400 W it reports during mfaktc "just" 290 to 300 W. But you still might be correct that a T4 has a better...

Hi,
you might want to include benchmarks for 2 workers and it is even better for certain ranges (FFT data fits twice into L3 cache(s) but not 4 times). Current LL Doublecheck fall into this...
