Radeon 610M

2023

Why buy it

✅62.3% more average FPS across 37 tracked games in our benchmark data.
✅Better long-term bet: RDNA 2.0 (2020−2025) on 5nm gives it a newer hardware base for upcoming games.
✅Draws 15W instead of 49W, a 34W reduction.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 11.8 G3D/$ (Unknown MSRP vs $99 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon 610M is the faster gaming card right now. In our data, it leads by 62.3% in average FPS across 37 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 640 Rev. 2 instead at 1,168 vs 1,157, 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 610M 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 5nm process instead of 28nm, 2 vs 0 ray-tracing units, and a newer 2023 generation instead of 2013. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GT 640 Rev. 2 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 640 Rev. 2 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 610M has the stronger long-term case.
