Frequently Asked Questions
Which GPU is better for AI training: H200 or A100 40GB?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The H200 offers 141GB of HBM3e memory with 4.8 TB/s bandwidth, while the A100 40GB provides 40GB of HBM2 with 1.5 TB/s bandwidth. For larger models, the H200's higher VRAM capacity gives it an advantage.
What is the price difference between H200 and A100 40GB in the cloud?
Cloud GPU rental prices vary by provider and region. Check our price tracker for the latest rates from 50+ cloud providers.
Can I use A100 40GB instead of H200 for my workload?
It depends on your specific requirements. If your model fits within 40GB of VRAM and you don't need the additional throughput of the H200, the A100 40GB can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the H200's NVLink support (NVLink 4.0 (900 GB/s)) may be essential.
