Power & Efficiency
- TDP
- 150 W
- Max power (Flopper estimate)
- ~173 W est.
- FP32 dense TFLOPS per W of TDP
- 0.21 TFLOPS/W
- FP16 dense TFLOPS per W of TDP
- 0.85 TFLOPS/W
Flopper estimate: 150 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.
