Frequently Asked Questions
Which GPU is better for AI training: Instinct MI300X or H200?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The Instinct MI300X offers 192GB of HBM3 memory with 5.3 TB/s bandwidth, while the H200 provides 141GB of HBM3e with 4.8 TB/s bandwidth. For larger models, the Instinct MI300X's higher VRAM capacity gives it an advantage.
What is the price difference between Instinct MI300X and H200 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, Instinct MI300X starts at $1.99/hour while H200 starts at $1.49/hour. This represents a 34% price difference.
Can I use H200 instead of Instinct MI300X for my workload?
It depends on your specific requirements. If your model fits within 141GB of VRAM and you don't need the additional throughput of the Instinct MI300X, the H200 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the Instinct MI300X's architecture may be essential.
