- geezerjay 10y agoA delta of $3000 per component buys you a whole lot of electricity. Furthermore, the performance of each of NVidia's GPUs falls somewhere between 5 and 20 teraFLOPs. A Haswell Xeon gets you about half a teraFLOP for around 1/3 of the power consumption of a NVidia Tesla P100 GPU.
- bonzini 10y agoI am not sure where you get those numbers. Both a Knights Landing Xeon Phi and a Tesla K80 are about 3 teraflops for $5000. Comparing GPUs with Xeons makes no sense.
