PERFORMANCE
Performance at 4K
The RTX 5080 16 GB at 4K in five game benchmarks, per GamersNexus: Resident Evil 4 hit 122 FPS, Final Fantasy XIV Dawntrail reached 112 FPS, Dragon's Dogma 2 ran at 84 FPS, Dying Light 2 at 81 FPS, and Starfield at 76 FPS.
The card has 16 GB of VRAM, with a 360 W TGP (Total Graphics Power) fed by the Asus Strix 1000W 80+ Gold PSU. The Ryzen 7 9800X3D is AMD's top gaming CPU in the 9000-series, with 3D V-Cache stacking additional cache on the die to reduce per-frame processing time in games. The 64 GB of DDR5 at 6400 MHz covers both gaming and heavier workloads like video editing or 3D rendering running alongside the game environment.
"At a price of $999, the Nvidia GeForce RTX 5080 is now easily the best sub-$1,000 graphics card."
