Quick Answers

Which GPU is faster for gaming right now?
Radeon Graphics (Ryzen 7000) is the faster gaming card right now. In our data, it leads by 157.6% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 645 instead at 2,006 vs 2,000, 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 Graphics (Ryzen 7000) is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 28nm, and a newer 2022 generation instead of 2012. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
GeForce GT 645 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, GeForce GT 645 is the easier value choice. If you care more about 1080p headroom, Radeon Graphics (Ryzen 7000) has the stronger long-term case.
