Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 580X is the faster gaming card right now. In our data, it leads by 71.5% in average FPS across 50 tracked games in our benchmark data and by 5.6% in PassMark G3D (7,495 vs 7,098), so the answer here is pretty clean.

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

RadeonT 780M is the safer long-term pick for 2026 and beyond. The case is simple: a 4nm process instead of 14nm, 12 vs 0 ray-tracing units, and a newer 2024 generation instead of 2018. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon RX 580X makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon RX 580X is the easier value choice. If you care more about 1080p and some 1440p headroom, RadeonT 780M has the stronger long-term case.
