See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

Radeon 660M

2023

Why buy it

✅1.8% more average FPS across 50 tracked games in our benchmark data.
✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 75W, a 35W reduction.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌Lower G3D Mark per dollar, at 0 vs 9.3 G3D/$ (Unknown MSRP vs $350 MSRP).

Radeon R9 M470X

2016

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 9.3 vs 0 G3D/$ ($350 MSRP vs Unknown MSRP).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌Lower average FPS than Radeon 660M across 50 tracked games in our benchmark data.
❌2016 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌87.5% higher power demand at 75W vs 40W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 660M is the faster gaming card right now. In our data, it leads by 1.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon R9 M470X instead at 3,244 vs 3,221, 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 660M is the safer long-term pick for 2026 and beyond. The case is simple: a 6nm process instead of 28nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2016. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon R9 M470X 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, Radeon R9 M470X is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 660M has the stronger long-term case.
