Performance Analysis
The 8.9 TFLOPS FP32 figure on the GTX 1080 remains well below the 67 TFLOPS FP32 rating on the H100 which creates a performance ratio exceeding seven times in favor of the newer card for standard floating point tasks. The H100 also lists 989 TFLOPS FP16 dense and 1979 TFLOPS FP16 with sparsity while the GTX 1080 has no FP16 value published by the vendor. Such tensor differences determine suitability for operations that rely on lower precision formats during model execution.

When to Choose the GTX 1080
The GTX 1080 fits scenarios that require only 180W TDP and 8.9 TFLOPS FP32 within PCIe form factors. Its 320 GB/s bandwidth and 8-11 GB VRAM support basic graphics or small scale computations where power limits and older interconnects already exist.
When to Choose the H100
The H100 suits workloads that need 67 TFLOPS FP32 or 989 TFLOPS FP16 dense along with 3350 GB/s bandwidth and 80-94 GB VRAM. Its 700W TDP and NVLink options align with large model handling in SXM5 or NVL configurations.
Use Cases
The H100 supplies 989 TFLOPS FP16 dense and 3350 GB/s bandwidth that enable larger models than the GTX 1080 8.9 TFLOPS FP32 can support.
The H100 1979 TFLOPS FP16 with sparsity and 80-94 GB VRAM allow higher throughput than the GTX 1080 limited 8-11 GB capacity.
The H100 67 TFLOPS FP32 and 3350 GB/s bandwidth handle parameter updates at scales beyond the GTX 1080 320 GB/s limit.
The GTX 1080 8.9 TFLOPS FP32 suffices for small batches while the H100 989 TFLOPS FP16 dense accelerates larger image generation.
The H100 67 TFLOPS FP32 exceeds the GTX 1080 8.9 TFLOPS FP32 and pairs with 3350 GB/s bandwidth for intensive simulations.
Frequently Asked Questions
How does FP32 performance compare between the GTX 1080 and H100?▾
The GTX 1080 lists 8.9 TFLOPS FP32 while the H100 lists 67 TFLOPS FP32. This creates a ratio greater than seven times in favor of the H100.
What memory bandwidth values appear for each GPU?▾
The GTX 1080 reaches 320 GB/s and the H100 reaches 3350 GB/s. The difference affects data movement rates during computation.
Which GPU offers higher FP16 dense performance?▾
The H100 provides 989 TFLOPS FP16 dense while the GTX 1080 has no FP16 figure published by the vendor. Direct comparison therefore uses only the available FP32 numbers.
What TDP ratings distinguish the two cards?▾
The GTX 1080 carries a 180W TDP and the H100 carries a 700W TDP. Power delivery requirements follow these published values.
Which is cheaper to rent, the GTX 1080 or the H100?▾
Cloud rental prices for both the GTX 1080 and H100 vary by provider, configuration, and availability. This page shows live pricing from 25+ providers updated every 60 seconds. Scroll to the Live Cloud Pricing section to compare current rates.
How much VRAM does the GTX 1080 have compared to the H100?▾
The GTX 1080 has 8 to 11 GB of GDDR5X memory. The H100 has 80 to 94 GB of HBM3 memory.
Can I find GTX 1080 and H100 GPUs available to rent right now?▾
Yes. This page shows real-time availability across 25+ cloud GPU providers. The Live Cloud Pricing section displays only in-stock offers with current pricing.
What is the main difference between the GTX 1080 and the H100?▾
The GTX 1080 uses the Pascal architecture (2016) while the H100 uses Hopper (2022). The GTX 1080 has 8-11 GB of GDDR5X at 320 GB/s; the H100 has 80-94 GB of HBM3 at 3,350 GB/s, so the H100 has 10.5x the memory bandwidth of the GTX 1080.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the GTX 1080 and the H100. 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.
