Performance Analysis
FP16 dense performance reaches 989 TFLOPS on the H100 while FP16 with sparsity reaches 222.2 TFLOPS on the RTX A5000. FP32 performance equals 67 TFLOPS on the H100 against 27.8 TFLOPS on the RTX A5000. The FP16 dense figure of 989 TFLOPS on the H100 supports larger training batches than the FP16 with sparsity figure of 222.2 TFLOPS on the RTX A5000 because memory bandwidth of 3350 GB/s versus 768 GB/s permits greater data movement per second during matrix operations.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the H100 and the RTX A5000. 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.
