GRID M60-1B vs RadeonT 660M: Pros, Cons & Final Verdict

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

GRID M60-1B

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 0.9 vs 0 G3D/$ ($2,500 MSRP vs Unknown MSRP).

Trade-offs

❌2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌462.5% higher power demand at 225W vs 40W.

RadeonT 660M

2023

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 225W, a 185W reduction.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 0.9 G3D/$ (Unknown MSRP vs $2,500 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

GRID M60-1B is the faster gaming card right now based on the synthetic data we have. It leads by 1.6% in PassMark G3D (2,256 vs 2,221), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

RadeonT 660M 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, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2015. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GRID M60-1B 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, GRID M60-1B is the easier value choice. If you care more about 1080p and some 1440p headroom, RadeonT 660M has the stronger long-term case.
