Frequently Asked Questions
Which GPU is better for AI training: P40 or T4G?
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 T4G provides 16GB of GDDR6 with 320 GB/s bandwidth. For larger models, the P40's higher VRAM capacity gives it an advantage.
What is the price difference between P40 and T4G in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, P40 starts at $0.51/hour while T4G starts at $0.23/hour. This represents a 122% price difference.
Can I use T4G instead of P40 for my workload?
It depends on your specific requirements. If your model fits within 16GB of VRAM and you don't need the additional throughput of the P40, the T4G can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the P40's architecture may be essential.
