Quick Answers

Which GPU is faster for gaming right now?

Iris Pro Graphics P6300 is the faster gaming card right now based on the synthetic data we have. It leads by 1% in PassMark G3D (1,582 vs 1,567), which is the best performance signal available in this matchup.

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

Radeon HD 6790 is the safer long-term pick for 2026 and beyond. The case is simple: 1 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?

Iris Pro Graphics P6300 makes the most sense to buy today. It is $1 more expensive on MSRP at $150 vs $149, and it leads G3D-per-dollar by 0.3% (10.5 vs 10.5), so the value case lines up with the gaming result. If you are mainly targeting 1080p, Iris Pro Graphics P6300 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon HD 6790 has the stronger long-term case.
