Verdict

NVIDIA L40S

8.9 / 10 Expert Rating

One of the most widely deployed data center GPUs of its generation - a genuinely strong middle ground between pure graphics cards and dedicated AI accelerators.

NVIDIA GeForce RTX 5090 D

8.9 / 10 Expert Rating

A very fast card held back only by a few percent of artificially capped performance; still the fastest GeForce card available in its home market.
