GeForce RTX 4080 Super vs Radeon RX 7900 XTX

Desktop GPU comparison · NVIDIA vs AMD · 2024 vs 2022

Estimates only. These calculators use typical component specifications and rough rules of thumb. They are for planning and education, not purchase advice. Verify every number against your parts’ official datasheets before buying or building.
Why a static comparison: AI search can list each part's spec sheet, but it cannot lay the two side by side with a grounded pick guidance calibrated to your workload. That is what this page does — every number below comes from the vendor datasheet / TechPowerUp entry.

Which one should you pick?

The two are within ~2 tier points of each other, so the relative-performance index does not clearly separate them. 24 GB VRAM on the larger card vs 16 GB. Tier is a TweakGearPro planning estimate, not a benchmark — verify with reviews that match your exact workload, resolution and workload mix before buying.

Specs: vendor datasheets / TechPowerUp database, retrieved 2026-08-29. Tier is a TweakGearPro relative performance index (estimate), not a benchmark guarantee.
