Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

Both launched in 2016, the P100 on Pascal and the Tesla P40 on Pascal.

The Tesla P40 carries 8 GB more memory (24 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 732 GB/s against 346 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 250 W, and at FP32 the Tesla P40 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Is the P100 faster than the Tesla P40?

At FP32 precision the Tesla P40 reaches 12 TFLOPS dense against 11 TFLOPS for the P100. The performance table on this page lists every published precision for both GPUs.

Which should you choose, the P100 or the Tesla P40?

Choose the Tesla P40 for training and high-throughput inference: it has 13% more FP32 throughput than the P100. It also carries 8 GB more memory, so larger models fit on one GPU before you shard. The Tesla P40 draws 50 W less power, which matters in an air-cooled or power-capped rack. Packaging differs too: the P100 is an SXM module while the Tesla P40 is a PCIe card, so check what your servers accept.

Which has more memory, the P100 or the Tesla P40?

The Tesla P40 carries 24 GB of memory versus 16 GB for the P100. Memory bandwidth is 732 GB/s for the P100 and 346 GB/s for the Tesla P40.

How much power do the P100 and the Tesla P40 draw?

The P100 is rated at 300 W TDP and the Tesla P40 at 250 W. On FP32 throughput per watt, the Tesla P40 is the more efficient part.

How much do the P100 and the Tesla P40 cost to rent?
