FLOPS by Precision

What actually differs

Both launched in 2016, the Tesla P4 on Pascal and the Tesla P40 on Pascal.

The Tesla P40 carries 16 GB more memory (24 GB against 8 GB), so larger models fit on one GPU before you shard. Bandwidth is 192 GB/s against 346 GB/s, which sets the ceiling on decode speed.

Power is 75 W against 250 W, and at FP32 the Tesla P4 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
