Yes. The NVIDIA RTX 5090 is about 26% faster overall, averaging roughly NaN FPS versus NaN FPS for the NVIDIA RTX 4090 at 4K with optimized settings across popular games.
About 26% faster on average. The exact gap varies by game and resolution — heavier, GPU-bound games show the biggest difference.
A 26% jump is a moderate upgrade — worth it if you're chasing higher settings or frame rates. The NVIDIA RTX 5090 also carries more VRAM (32GB vs 24GB), which helps at higher resolutions and with high-res textures.
FPS figures are estimates from a generalized model (hardware tier × game load × per-setting weights), not live benchmarks — real performance varies by scene, drivers and game version.
