Power & Efficiency
- TDP
- 1.0 kW
- Max power (Flopper estimate)
- ~1.1 kW est.
- FP32 dense TFLOPS per W of TDP
- 0.16 TFLOPS/W
- FP16 dense TFLOPS per W of TDP
- 1.31 TFLOPS/W
Flopper estimate: 1000 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.
