NVIDIA GeForce RTX 3090 vs AMD Radeon RX 6800
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 3090 is faster but costs more. The AMD Radeon RX 6800 offers better value for money. Your choice depends on budget vs. performance priority.
NVIDIA GeForce RTX 3090 vs AMD Radeon RX 6800: Which Should You Buy?
The NVIDIA GeForce RTX 3090 is 19% faster at 1440p ultra (106 fps against 89.2 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 159% premium for the NVIDIA GeForce RTX 3090 ($1,499 against $579) to get 19% more frames. The extra frames do not keep up with the extra cost — the AMD Radeon RX 6800 is the better value here.
Two things beyond raw speed: NVIDIA GeForce RTX 3090 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 AMD Radeon RX 6800 draws 100W less (250W versus 350W), which can mean a smaller PSU and a quieter case.
