Quick Answers

Which GPU is faster for gaming right now?

Arc B580 is the faster gaming card right now. In our data, it leads by 2.3% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 7800M instead at 15,984 vs 15,977, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon RX 7800M is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while Arc B580 is limited to no meaningful modern upscaling stack and no comparable frame-generation support and 60 vs 20 ray-tracing units. That still leaves it as the safer long-term option on hardware alone.

Which GPU is the better buy today?

Arc B580 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and lighter 1440p, Arc B580 is the easier value choice. If you care more about 1080p and lighter 1440p headroom, Radeon RX 7800M has the stronger long-term case.
