Power & Efficiency

TDP: 350 W
Max power (Flopper estimate): ~402 W est.
FP32 dense TFLOPS per W of TDP: 0.15 TFLOPS/W
FP16 dense TFLOPS per W of TDP: 2.16 TFLOPS/W

Flopper estimate: 350 W TDP x 1.15. The vendor publishes no maximum board power for this part. Per W of TDP figures divide dense peak by accelerator TDP. Board power only: excludes host CPUs, networking, cooling and facility overhead.
