Radeon 660M vs Radeon R7 260X: Pros, Cons & Final Verdict

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

  • 4.6% 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 115W, a 75W reduction.

Trade-offs

  • Lower G3D Mark per dollar, at 0 vs 23.0 G3D/$ (Unknown MSRP vs $139 MSRP).

Radeon R7 260X

2013

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 23.0 vs 0 G3D/$ ($139 MSRP vs Unknown MSRP).

Trade-offs

  • Lower average FPS than Radeon 660M across 50 tracked games in our benchmark data.
  • 2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 187.5% higher power demand at 115W 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 4.6% in average FPS across 50 tracked games in our benchmark data and by 0.7% in PassMark G3D (3,221 vs 3,198), so the answer here is pretty clean.
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 2013. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon R7 260X 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 R7 260X is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 660M has the stronger long-term case.
