Power & Efficiency

TDP: 180 W
Max power (Flopper estimate): ~207 W est.
FP32 dense TFLOPS per W of TDP: 0.17 TFLOPS/W
FP16 dense TFLOPS per W of TDP: —

Flopper estimate: 180 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.
