GRID T4-1Q vs Radeon 660M Performance Spectrum

About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

GRID T4-1Q vs Radeon 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 T4-1Q

2015

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 1.8 vs 0 G3D/$ ($1,880 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.

Radeon 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 1.8 G3D/$ (Unknown MSRP vs $1,880 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
GRID T4-1Q is the faster gaming card right now based on the synthetic data we have. It leads by 2.5% in PassMark G3D (3,303 vs 3,221), which is the best performance signal available in this matchup.
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: 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 T4-1Q 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 T4-1Q is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 660M has the stronger long-term case.
