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

GeForce GT 645

2012

Why buy it

  • Costs $61 less on MSRP ($99 MSRP vs $160 MSRP).
  • Delivers 63.1% more G3D Mark for each dollar spent, at 20.3 vs 12.4 G3D/$ ($99 MSRP vs $160 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
  • Draws 32W instead of 150W, a 118W reduction.
  • Measures 145mm instead of 210mm, a 65mm shorter card that is more SFF-friendly.

Trade-offs

  • Lower average FPS than GeForce GTX 460 SE across 50 tracked games in our benchmark data.
  • 2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

GeForce GTX 460 SE

2010

Why buy it

  • 101.9% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

  • Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
  • 2010 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 61.6% HIGHER MSRP
    $160 MSRPvs$99 MSRP
  • Lower G3D Mark per dollar, at 12.4 vs 20.3 G3D/$ ($160 MSRP vs $99 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
GeForce GTX 460 SE is the faster gaming card right now. In our data, it leads by 101.9% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 645 instead at 2,006 vs 1,988, so for this question the real-game FPS result matters more than the synthetic split.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GT 645 is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 1 GB of VRAM, a 28nm process instead of 40nm, and a newer 2012 generation instead of 2010. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
GeForce GT 645 makes the most sense to buy today. It is $61 cheaper on MSRP at $99 vs $160, and it leads G3D-per-dollar by 63.1% (20.3 vs 12.4), which is enough to swing the recommendation its way. GeForce GTX 460 SE still makes more sense if max raw gaming performance matters more than value.
