Frequently Asked Questions
Which GPU is better for AI training: B200 or A30?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The B200 offers 192GB of HBM3e memory with 8.0 TB/s bandwidth, while the A30 provides 24GB of HBM2 with 933 GB/s bandwidth. For larger models, the B200's higher VRAM capacity gives it an advantage.
What is the price difference between B200 and A30 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, B200 starts at $2.25/hour while A30 starts at $0.11/hour. This represents a 1945% price difference.
Can I use A30 instead of B200 for my workload?
It depends on your specific requirements. If your model fits within 24GB of VRAM and you don't need the additional throughput of the B200, the A30 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the B200's NVLink support (NVLink 5.0 (1.8 TB/s)) may be essential.
