H100 SXM5 80GB Rental Guide
Renting the H100 SXM5 80GB makes sense when your workload requires 80GB of HBM3 memory and 1979 TFLOPS of FP16 compute. The most common use cases are LLM training, Large-scale inference, Scientific HPC. Before committing to a rental, verify that your model and batch size fit within 80GB — a 70B parameter model requires approximately 140GB at FP16, which would require two H100 SXM5 80GB instances with tensor parallelism.
For fault-tolerant batch workloads — preprocessing, offline inference, or training with checkpointing — spot instances typically save 40–70% vs on-demand rates. The H100 SXM5 80GB's 80GB VRAM makes it well-suited for long-running batch jobs where interruption recovery is manageable. On-demand instances give you full control with no commitment — ideal for development, short experiments, and workloads with unpredictable duration. Most providers bill per second or per minute, so short jobs are not penalized by hourly minimums.
For sustained production inference serving, reserved instances (1–3 month commitments) typically offer 20–35% savings vs on-demand. The H100 SXM5 80GB's high throughput makes it cost-effective for high-volume inference where per-token cost matters. When comparing providers, look beyond the headline hourly rate: check region availability (latency matters for interactive inference), spot interruption frequency, and whether the provider offers per-second billing. Use the GPU cost calculator to model total cost across different billing models and utilization rates before choosing a provider.
Frequently Asked Questions
How much does it cost to rent a H100 SXM5 80GB?
H100 SXM5 80GB on-demand rental prices vary by provider and region. On-demand rates typically range based on availability and provider margins — use the comparison table above to see current live rates across all providers. Spot instances are generally 40–70% cheaper than on-demand but can be interrupted. Monthly cost estimates (hourly rate × 730 hours) are shown in the table for sustained workloads.
Which cloud provider has the cheapest H100 SXM5 80GB?
The cheapest H100 SXM5 80GB provider changes as providers update their pricing. The comparison table above shows live rates sorted by price, so the cheapest option is always at the top. Factors beyond headline price include region (latency to your users), availability (high/medium/low), and billing granularity (per-second vs per-hour minimums).
What can I run on a H100 SXM5 80GB?
With 80GB of HBM3, the H100 SXM5 80GB can run LLM models up to approximately 40B parameters at FP16, 80B at INT8, or 160B at INT4/GGUF quantization. Common workloads include: LLM training, Large-scale inference, Scientific HPC. SXM5 form factor H100 with maximum NVLink bandwidth. The gold standard for large-scale AI training. Higher bandwidth than PCIe variant.
Should I use on-demand or spot pricing for H100 SXM5 80GB?
Spot instances save 40–70% vs on-demand but can be interrupted when the provider needs capacity back. Use spot for: batch inference jobs, training runs with checkpointing, preprocessing pipelines, and any workload that can tolerate interruption and restart. Use on-demand for: production inference serving, interactive workloads, and jobs that cannot be interrupted. Most providers bill per second, so short on-demand jobs are not penalized by hourly minimums.
How does the H100 SXM5 80GB compare to the H100 for cloud rental?
The H100 80GB delivers 1,979 TFLOPS FP16 with 3,350 GB/s HBM3 bandwidth, compared to the H100 SXM5 80GB's 1979 TFLOPS FP16 and 3350 GB/s bandwidth. The H100 is significantly more expensive — typically $2.50–$5.00/hr vs lower rates for the H100 SXM5 80GB. For workloads that fit within 80GB and don't require FP8 precision, the H100 SXM5 80GB often delivers better cost-per-token than the H100.
What is the memory bandwidth of the H100 SXM5 80GB and why does it matter?
The H100 SXM5 80GB has 3350 GB/s of memory bandwidth. For LLM inference, memory bandwidth is often more important than raw TFLOPS — each autoregressive token generation reads the full model weight matrix from VRAM, so bandwidth directly determines tokens-per-second throughput. Higher bandwidth means faster inference for the same model at the same batch size. For batch inference (processing many requests simultaneously), compute throughput becomes more important.
Can I use the H100 SXM5 80GB for Stable Diffusion or image generation?
Yes — the H100 SXM5 80GB is well-suited for Stable Diffusion and image generation workloads. Image generation is primarily FP32 and FP16 compute-bound, and the H100 SXM5 80GB's 67 TFLOPS FP32 throughput determines images-per-second. The 80GB VRAM fits SDXL (requires ~6GB) and most ControlNet pipelines. For high-throughput image generation at scale, compare cost-per-image across providers using the GPU cost calculator.
