H100 PCIe 80GB vs L40S: which should you choose?
H100 PCIe 80GB — NVIDIA desktop graphics card (2022, Hopper) with 80 GB of HBM2e, averaging 89 fps at 1440p.
L40S — NVIDIA desktop graphics card (2023, Ada Lovelace) with 48 GB of GDDR6, averaging 148 fps at 1440p.
H100 PCIe 80GB vs L40S: L40S is faster for gaming. L40S averages 148 fps at 1440p versus 89 fps — about 40% faster.
1080p, 1440p and 4K
At 1440p — the most common enthusiast resolution — the L40S averages 148 fps against 89. At 4K (50 vs 84 fps) VRAM (80GB vs 48GB) and memory bandwidth matter more.
AI and creator workloads
Beyond gaming, the L40S is quicker for AI image generation (36.6 vs 20.5 it/s in Stable Diffusion) and local LLM inference (143 vs 53 tokens/s), which increasingly matters for creators and developers.
Power and value
Board power is 350 W versus 350 W, which affects PSU headroom, case cooling and noise.
The verdict
Both are credible choices in the graphics card comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
