Frequently Asked Questions
Which GPU is better for AI training: P40 or K80?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The P40 offers 24GB of GDDR5 memory with 347 GB/s bandwidth, while the K80 provides 24GB of GDDR5 with 480 GB/s bandwidth. Both GPUs have similar VRAM capacity, so performance characteristics become the deciding factor.
What is the price difference between P40 and K80 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, P40 starts at $0.51/hour while K80 starts at $0.10/hour. This represents a 410% price difference.
Can I use K80 instead of P40 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 P40, the K80 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the P40's architecture may be essential.
