NVIDIA GeForce RTX 3090 Ti vs NVIDIA GeForce RTX 4080
Side-by-side benchmark comparison, specs, pricing, and value analysis.
Benchmark Comparison
Gaming figures are average frames per second, measured by Tom's Hardware GPU hierarchy. Geometric mean of 15 games, ultra settings, no upscaling. Ray tracing figures are DXR-enabled at 1440p. A dash means the card was not tested at that resolution. Productivity and Steel Nomad are synthetic scores on their own scales and are not comparable to the fps columns.

Verdict
The NVIDIA GeForce RTX 4080 is the clear winner — it offers both better performance and better value.
NVIDIA GeForce RTX 3090 Ti vs NVIDIA GeForce RTX 4080: Which Should You Buy?
The NVIDIA GeForce RTX 4080 is 16% faster at 1440p ultra (130.4 fps against 112.7 fps). That is roughly one settings notch — enough to matter if you are chasing a specific refresh rate, not enough to rescue a bad price.
Pricing settles it: the NVIDIA GeForce RTX 4080 is both faster and 67% cheaper at $1,199 versus $1,999. There is no scenario in this pairing where the NVIDIA GeForce RTX 3090 Ti is the better buy at these prices.
Two things beyond raw speed: NVIDIA GeForce RTX 3090 Ti carries 24GB against 16GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 16GB cards age badly; and the NVIDIA GeForce RTX 4080 draws 130W less (320W versus 450W), which can mean a smaller PSU and a quieter case.
