Memory BW? Power consumption ? What's the BW and the power consumption of 2 A64FX CPUs, and what's the BW and power consumption of 4x Threadripper 3990X that also deliver 6 TFLOP/s? You might need to add the power for cooling to the comparison as well if you plan to stock a full cluster with these.
Also, if your main metric is TFLOPs, you might want to add a single A100 to the comparison.... it probably crushes the Threadripper and the A64FX from the POV of TFLOPs, memory BW, and power consumption, but maybe not price.
