| Theoretical peak speed: (64 cores) * (2.7 Gcycles/s/core) * (16 DP flop/cycle) = 5.5 Tflop/s, double precision |
| Assumes two AVX-512 FMA (fused multiply-add with 8 DP additions and 8 DP multiplications) every cycle |
| Does not account for memory bandwidth limitations, or dynamic frequency scaling due to AVX-512 instructions |
