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.

Radeon 660M vs Tesla K40m: 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

  • Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
  • Draws 40W instead of 245W, a 205W reduction.
  • More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

  • Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Tesla K40m

2013

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • 2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 512.5% higher power demand at 245W vs 40W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon 660M is the faster gaming card right now based on the synthetic data we have. It leads by 2.5% in PassMark G3D (3,221 vs 3,143), 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 2013. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon 660M makes the most sense today based on the pricing and value data we have for this matchup.
