Quick Answers

Which GPU is faster for gaming right now?

Quadro P620 is the faster gaming card right now. In our data, it leads by 0.9% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 550X (móvel) instead at 3,800 vs 3,698, 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 550X (móvel) is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR Upscaling / FSR 4 (2025) and FSR Frame Generation (2023), while Quadro P620 is limited to no meaningful modern upscaling stack and no comparable frame-generation support. That still leaves it as the safer long-term option on hardware alone.

Which GPU is the better buy today?

Radeon RX 550X (móvel) makes the most sense to buy today. It is $135 cheaper on MSRP at $35 vs $170, and it leads G3D-per-dollar by 399.1% (108.6 vs 21.8), which is enough to swing the recommendation its way. Quadro P620 still makes more sense if max raw gaming performance matters more than value.
