FLOPS by Precision

What actually differs

The Titan Xp is the newer part: Pascal (2017) against the Tesla P40's Pascal (2016).

The Tesla P40 carries 12 GB more memory (24 GB against 12 GB), so larger models fit on one GPU before you shard. Bandwidth is 346 GB/s against 548 GB/s, which sets the ceiling on decode speed.

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