Frequently Asked Questions
Which GPU is better for AI training: V100 or K80?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The V100 offers 32GB of HBM2 memory with 900 GB/s bandwidth, while the K80 provides 24GB of GDDR5 with 480 GB/s bandwidth. For larger models, the V100's higher VRAM capacity gives it an advantage.
What is the price difference between V100 and K80 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, V100 starts at $0.13/hour while K80 starts at $0.10/hour. This represents a 30% price difference.
Can I use K80 instead of V100 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 V100, the K80 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the V100's architecture may be essential.
