Yes. The NVIDIA RTX 4090 is about 148% faster overall, averaging roughly NaN FPS versus NaN FPS for the Intel Arc B580 at 1080p with optimized settings across popular games.
About 148% faster on average. The exact gap varies by game and resolution — heavier, GPU-bound games show the biggest difference.
A 148% jump is a meaningful upgrade worth considering. The NVIDIA RTX 4090 also carries more VRAM (24GB vs 12GB), 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.
