Quick Answers

Which GPU is faster for gaming right now?

Radeon Ryzen 7 5700U is the faster gaming card right now. In our data, it leads by 77.9% in average FPS across 50 tracked games in our benchmark data and by 2.2% in PassMark G3D (2,219 vs 2,172), so the answer here is pretty clean.

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

Radeon RX 640 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM and native frame generation with FSR Frame Generation + AFMF (2023), while Radeon Ryzen 7 5700U has no comparable frame-generation support. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 640 makes the most sense to buy today. It is $291 cheaper on MSRP at $159 vs $450, and it leads G3D-per-dollar by 177% (13.7 vs 4.9), which is enough to swing the recommendation its way. Radeon Ryzen 7 5700U still makes more sense if max raw gaming performance matters more than value.
