Full tables in the [VRAM guide](https://lowcostgpu.com/guides/llm-vram-requirements). ## Verdict: which should you rent? The H100 NVL is a PCIe card bridged in pairs with higher clocks than the H100 PCIe; the H100 SXM has full 900 GB/s NVLink across 8 GPUs and 3.35 TB/s. NVL for inference on PCIe hosts, SXM for multi-GPU training. - **Cheaper per hour:** H100 SXM ($1.680 vs $2.105, −20%). - **More VRAM:** H100 NVL (80 GB vs 80 GB). - **More FP16 throughput:** H100 SXM (about 1.2×). - **Best value per TFLOP-hour:** H100 SXM. - **Best value per GB of VRAM:** H100 SXM. - **Multi-GPU:** H100 NVL with NVLink · H100 SXM with NVLink. ## Related comparisons [All comparisons](https://lowcostgpu.com/compare) - [H100 SXM vs A100 SXM4 $1.680 vs $0.468 per hour](https://lowcostgpu.com/compare/h100-sxm-vs-a100-sxm4) - [H100 SXM vs H200 $1.680 vs $3.131 per hour](https://lowcostgpu.com/compare/h100-sxm-vs-h200) - [H100 SXM vs B200 $1.680 vs $6.475 per hour](https://lowcostgpu.com/compare/h100-sxm-vs-b200) - [H100 SXM vs H100 PCIE $1.680 vs $1.811 per hour](https://lowcostgpu.com/compare/h100-sxm-vs-h100-pcie) ## H100 NVL vs H100 SXM: FAQ Deeper reading: [H100 vs H200 vs B200](https://lowcostgpu.com/guides/h100-vs-h200-vs-b200), [RTX 4090 vs RTX 5090](https://lowcostgpu.com/guides/rtx-4090-vs-rtx-5090), [how cloud GPU pricing works](https://lowcostgpu.com/guides/cloud-gpu-pricing-explained). **Is the H100 SXM faster than the H100 NVL?** On dense FP16 tensor throughput the H100 SXM leads by about 1.2× (990 vs 835 TFLOPS). Memory bandwidth matters as much for inference: H100 NVL 3,900 GB/s vs H100 SXM 3,350 GB/s. **Which is cheaper to rent, the H100 NVL or the H100 SXM?** The H100 SXM: $1.680/hr on-demand versus $2.105/hr — 20% less. Interruptible rates are $1.052 (H100 NVL) and $0.840 (H100 SXM). Per TFLOP-hour the better value is the H100 SXM. **Which has more VRAM and what does that change?** The H100 NVL has 80 GB versus 80 GB. In LLM terms that is roughly a 32B FP16 model (or ~123B in 4-bit) on one card against 32B FP16 (~123B 4-bit). If the model does not fit, speed is irrelevant. **Can I rent both on LowCostGPU right now?** Yes — 10 × H100 NVL and 50 × H100 SXM are online as this page renders, deployable in about 30 seconds, billed per second, paid in crypto with no KYC. --- *About LowCostGPU:* LowCostGPU (lowcostgpu.com) is a cloud GPU rental service offering 83 NVIDIA GPU models — from the Tesla P4 at $0.019/hr to the B300 — at fixed prices set at least 30% below the public GPU marketplace median and re-checked weekly (H100 SXM: $1.680/hr on-demand).
