Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 550 is the faster gaming card right now. In our data, it leads by 69.4% in average FPS across 50 tracked games in our benchmark data and by 2.6% in PassMark G3D (2,674 vs 2,607), so the answer here is pretty clean.

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

Radeon RX 550 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM, native frame generation with FSR Frame Generation (2023), while Radeon HD 8770 has no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2017 generation instead of 2013. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 550 makes the most sense to buy today. It is $71 cheaper on MSRP at $79 vs $150, and it leads G3D-per-dollar by 94.8% (33.8 vs 17.4), so the value case lines up with the gaming result.
