NVIDIA GeForce RTX 4080 SUPER vs NVIDIA GeForce RTX 4090
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 4090 is faster but costs more. The NVIDIA GeForce RTX 4080 SUPER offers better value for money. Your choice depends on budget vs. performance priority.
NVIDIA GeForce RTX 4080 SUPER vs NVIDIA GeForce RTX 4090: Which Should You Buy?
The NVIDIA GeForce RTX 4090 is 10% faster at 1440p ultra (146.1 fps against 133 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 60% premium for the NVIDIA GeForce RTX 4090 ($1,599 against $999) to get 10% more frames. The extra frames do not keep up with the extra cost — the NVIDIA GeForce RTX 4080 SUPER is the better value here.
Two things beyond raw speed: NVIDIA GeForce RTX 4090 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 SUPER draws 130W less (320W versus 450W), which can mean a smaller PSU and a quieter case; and the NVIDIA GeForce RTX 4080 SUPER is 2 years newer (2024 versus 2022), so it gets longer driver support and newer upscaling and frame generation features.
