Power efficiency analysis
TFLOPS/watt and GB/s/watt — critical for data center TCO
NVIDIA GB200 NVL72
NVIDIA H200 141GB
TFLOPS/watt measures compute efficiency — how much AI throughput you get per watt of power consumed. For data centers with PUE of 1.2–1.5, a 10% improvement in TFLOPS/watt translates directly to lower electricity costs and cooling requirements. GB/s/watt measures memory bandwidth efficiency, which is the binding constraint for memory-bound LLM inference workloads.
Performance-per-dollar
TFLOPS/$ and GB/s/$ at current best cloud prices
NVIDIA GB200 NVL72
NVIDIA H200 141GB
TFLOPS/$ = FP16 TFLOPS ÷ best on-demand $/hr. Higher is better — more compute per dollar. GB/s/$ = memory bandwidth ÷ best on-demand $/hr. For memory-bound inference workloads (most LLM serving), GB/s/$ is often a better predictor of cost-efficiency than TFLOPS/$. Prices are live from the Compute Comparison API and update in real time.
Workload Cost Comparison
Total job cost = best on-demand $/hr × GPU count × hours
| Workload | Scale | NVIDIA GB200 NVL72 | NVIDIA H200 141GB |
|---|---|---|---|
| 7B LLM fine-tune | 8× GPU, 24 h | — | $501 |
| 70B LLM fine-tune | 64× GPU, 72 h | — | $12k |
| Inference server | 1× GPU, 730 h | — | $1.9k |
| Image gen batch | 4× GPU, 8 h | — | $84 |
Based on current best on-demand prices. Spot pricing typically 40–70% lower. Actual cost depends on provider, region, and availability.
When to choose each GPU
Choose NVIDIA GB200 NVL72 for:
- Trillion-parameter training
- AI factory scale
- Next-gen LLM inference
Weaknesses / Limitations
- Rack-scale system — not a single GPU, requires full NVL72 rack deployment
- 2,700W system TDP demands dedicated power and liquid cooling infrastructure
- Extremely limited availability — primarily hyperscaler and large enterprise
Choose NVIDIA H200 141GB for:
- Very large LLMs
- Memory-bound inference
- Multi-modal models
Weaknesses / Limitations
- Very limited cloud availability — fewer providers than H100
- Premium pricing over H100 with same FP16 TFLOPS
- 700W TDP — same power envelope as H100 with no efficiency gain
