Quick Answers

Which GPU is faster for gaming right now?

Iris Pro Graphics P580 is the faster gaming card right now based on the synthetic data we have. It leads by 1.4% in PassMark G3D (2,026 vs 1,998), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon R9 350 is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM and the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon R9 350 makes the most sense to buy today. It is $51 cheaper on MSRP at $99 vs $150, and it leads G3D-per-dollar by 49.4% (20.2 vs 13.5), which is enough to swing the recommendation its way. Iris Pro Graphics P580 still makes more sense if max raw gaming performance matters more than value.
