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 vs Tesla P40: 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

2019

Why buy it

  • Costs $5,480 less on MSRP ($219 MSRP vs $5,699 MSRP).
  • Delivers 2465% more G3D Mark for each dollar spent, at 53.1 vs 2.1 G3D/$ ($219 MSRP vs $5,699 MSRP).
  • Tesla P40 is already legacy-tier future-proofing, so GeForce GTX 1660 is the less risky modern option long term.
  • Draws 120W instead of 250W, a 130W reduction.
  • Measures 229mm instead of 267mm, a 38mm shorter card that is more SFF-friendly.

Trade-offs

  • Less VRAM, with 6 GB vs 24 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.

Tesla P40

2016

Why buy it

  • 300% more VRAM for high-resolution textures and newer games (24 GB vs 6 GB).

Trade-offs

  • 2016 hardware with 24 GB of VRAM already sits in legacy territory for modern games.
  • 2502.3% HIGHER MSRP
    $5,699 MSRPvs$219 MSRP
  • Lower G3D Mark per dollar, at 2.1 vs 53.1 G3D/$ ($5,699 MSRP vs $219 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
Tesla P40 is the faster gaming card right now based on the synthetic data we have. It leads by 1.5% in PassMark G3D (11,808 vs 11,639), 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 is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 16nm and a newer 2019 generation instead of 2016. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
GeForce GTX 1660 makes the most sense to buy today. It is $5,480 cheaper on MSRP at $219 vs $5,699, and it leads G3D-per-dollar by 2465% (53.1 vs 2.1), which is enough to swing the recommendation its way. Tesla P40 still makes more sense if max raw gaming performance matters more than value.
