Frequently Asked Questions
Which GPU is better for AI training: A800 or V100?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The A800 offers 80GB of HBM2e memory with 2.0 TB/s bandwidth, while the V100 provides 32GB of HBM2 with 900 GB/s bandwidth. For larger models, the A800's higher VRAM capacity gives it an advantage.
What is the price difference between A800 and V100 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, A800 starts at $0.80/hour while V100 starts at $0.13/hour. This represents a 515% price difference.
Can I use V100 instead of A800 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 A800, the V100 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the A800's architecture may be essential.
