Performance Analysis
Dense FP16 performance on the H100 measures 989 TFLOPS against 40.3 TFLOPS dense FP16 on the RTX 2080. This difference scales training throughput by a factor derived directly from those two figures. FP32 to dense FP16 ratios equal 67 TFLOPS to 989 TFLOPS on the H100 and 10 TFLOPS to 40.3 TFLOPS on the RTX 2080. Higher memory bandwidth of 3350 GB/s versus 448 GB/s permits larger batch sizes before memory capacity constraints appear. Sparse FP16 figures of 1979 TFLOPS on the H100 compare only to other sparse values while dense figures compare only to other dense values. The 700W TDP versus 215W TDP further separates sustained operation envelopes for extended workloads.

When to Choose the H100
The H100 suits scenarios that demand 989 TFLOPS dense FP16 or 1979 TFLOPS dense FP8. Its 80 to 94 GB HBM3 VRAM and 3350 GB/s bandwidth support models that exceed 11 GB capacity limits of the RTX 2080. Form factors including SXM5 and NVL enable NVLink interconnects for multi GPU scaling.
When to Choose the RTX 2080
The RTX 2080 fits workloads limited to 10 TFLOPS FP32 or 40.3 TFLOPS dense FP16. Its 215W TDP allows operation in standard PCIe slots without 700W power infrastructure. The 8 to 11 GB GDDR6 configuration handles smaller inference tasks that fit within those bounds.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the H100 and the RTX 2080. 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.
