## Memory Bandwidth

Source: pytorch

| Metric | Value | Peak | Efficiency |
|--------|-------|------|------------|
| H2D (PCIe) | 11.8 GB/s | 0 GB/s | 0.0% |
| D2H (PCIe) | 10.1 GB/s | 0 GB/s | 0.0% |
| D2D (NVLink) | 829.0 GB/s | 3400 GB/s | 24.4% |

**Verdict: WARN** (D2D 829.0 GB/s via PyTorch fallback; nvbandwidth unavailable — figure is indicative only, not a true HBM peak)

## Compute Throughput

| DType | Achieved (TFLOPS) | Peak | Threshold | Status |
|-------|-------------------|------|------------|--------|
| FP32 | 51.9 | 67 | >= 54 | WARN |
| TF32 | 357.8 | 495 | >= 444 | FAIL |
| FP16 | 667.2 | 990 | >= 734 | WARN |
| BF16 | 699.1 | 990 | >= 745 | WARN |
| FP8 | 1146.2 | 1979 | >= 1400 | FAIL |

**Verdict: FAIL** (absolute TFLOPS thresholds; worst efficiency 57.9%)
