Frequently Asked Questions
Which GPU is better for AI training: A30 or A100 80GB?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The A30 offers 24GB of HBM2 memory with 933 GB/s bandwidth, while the A100 80GB provides 80GB of HBM2e with 2.0 TB/s bandwidth. For larger models, the A100 80GB's higher VRAM capacity gives it an advantage.
What is the price difference between A30 and A100 80GB in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, A30 starts at $0.25/hour while A100 80GB starts at $0.40/hour. This represents a 38% price difference.
Can I use A100 80GB instead of A30 for my workload?
It depends on your specific requirements. If your model fits within 80GB of VRAM and you don't need the additional throughput of the A30, the A100 80GB can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the A30's architecture may be essential.
