NVIDIA GeForce RTX 3080 12 GB vs NVIDIA GeForce RTX 3090 Ti
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.

NVIDIA GeForce RTX 3080 12 GB vs NVIDIA GeForce RTX 3090 Ti: Which Should You Buy?
The NVIDIA GeForce RTX 3090 Ti is 10% faster at 1440p ultra (112.7 fps against 102.3 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.
You pay a 150% premium for the NVIDIA GeForce RTX 3090 Ti ($1,999 against $799) to get 10% more frames. The extra frames do not keep up with the extra cost — the NVIDIA GeForce RTX 3080 12 GB is the better value here.
Two things beyond raw speed: NVIDIA GeForce RTX 3090 Ti carries 24GB against 12GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 12GB cards age badly; and the NVIDIA GeForce RTX 3080 12 GB draws 100W less (350W versus 450W), which can mean a smaller PSU and a quieter case.
