Frequently Asked Questions
Which GPU is better for AI training: H100 SXM or V100S?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The H100 SXM offers 80GB of HBM3 memory with 3.35 TB/s bandwidth, while the V100S provides 32GB of HBM2 with 1.1 TB/s bandwidth. For larger models, the H100 SXM's higher VRAM capacity gives it an advantage.
What is the price difference between H100 SXM and V100S in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, H100 SXM starts at $0.73/hour while V100S starts at $0.88/hour. This represents a 17% price difference.
Can I use V100S instead of H100 SXM for my workload?
It depends on your specific requirements. If your model fits within 32GB of VRAM and you don't need the additional throughput of the H100 SXM, the V100S can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the H100 SXM's NVLink support (NVLink 4.0 (900 GB/s)) may be essential.
