Performance Analysis
The RTX 4080 supplies 5.2 times the FP32 performance of the P100 because 48.7 TFLOPS divided by 9.3 TFLOPS equals that ratio. In dense FP16 the RTX 4080 supplies 97.5 TFLOPS against the P100 18.7 TFLOPS dense FP16 so the same 5.2 times advantage appears. Memory bandwidth of 732 GB/s on the P100 versus 717 GB/s on the RTX 4080 limits batch sizes similarly yet the higher dense FP16 throughput on the RTX 4080 supports larger effective workloads in training and inference.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the P100 and the RTX 4080. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
