L40S vs RX 5500 XT: which should you choose?
L40S — NVIDIA desktop graphics card (2023, Ada Lovelace) with 48 GB of GDDR6, averaging 148 fps at 1440p.
RX 5500 XT — AMD desktop graphics card (2019, RDNA 1) with 8 GB of GDDR6, averaging 17 fps at 1440p; launched at $199.
L40S vs RX 5500 XT: L40S is faster for gaming. L40S averages 148 fps at 1440p versus 17 fps — about 771% faster. RX 5500 XT draws less power (130W vs 350W).
1080p, 1440p and 4K
At 1440p — the most common enthusiast resolution — the L40S averages 148 fps against 17. At 4K (84 vs 9 fps) VRAM (48GB vs 8GB) and memory bandwidth matter more.
AI and creator workloads
Beyond gaming, the L40S is quicker for AI image generation (36.6 vs 0.8 it/s in Stable Diffusion) and local LLM inference (53 vs 11 tokens/s), which increasingly matters for creators and developers.
Power and value
Board power is 350 W versus 130 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.
