GeForce GTX 1660 Ti (Mobile) vs Tesla M40 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.

GeForce GTX 1660 Ti (Mobile) vs Tesla M40: Pros, Cons & Final Verdict

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

GeForce GTX 1660 Ti (Mobile)

2020

Why buy it

  • Tesla M40 is already legacy-tier future-proofing, so GeForce GTX 1660 Ti (Mobile) is the less risky modern option long term.
  • Draws 50W instead of 250W, a 200W reduction.
  • More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 6 GB vs 8 GB for high-resolution textures and newer games.
  • Older hardware, 6 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • Lower G3D Mark per dollar, at 0 vs 4.1 G3D/$ (Unknown MSRP vs $2,500 MSRP).

Tesla M40

2015

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 4.1 vs 0 G3D/$ ($2,500 MSRP vs Unknown MSRP).
  • 33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).

Trade-offs

  • 2015 hardware with 8 GB of VRAM already sits in legacy territory for modern games.
  • 400% higher power demand at 250W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?
Tesla M40 is the faster gaming card right now based on the synthetic data we have. It leads by 1% in PassMark G3D (10,220 vs 10,119), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GTX 1660 Ti (Mobile) is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 28nm and a newer 2020 generation instead of 2015. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Tesla M40 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, Tesla M40 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GTX 1660 Ti (Mobile) has the stronger long-term case.
