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 30.6% in average FPS across 50 tracked games in our benchmark data and by 0.9% in PassMark G3D (15,977 vs 15,841), so the answer here is pretty clean.

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

Arc B580 is the safer long-term pick for 2026 and beyond. The case is simple: 12 GB vs 8 GB of VRAM, a 5nm process instead of 7nm, and a newer 2024 generation instead of 2022. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Arc B580 makes the most sense to buy today. It is $551 cheaper on MSRP at $249 vs $800, and it leads G3D-per-dollar by 224% (64.2 vs 19.8), so the value case lines up with the gaming result.
