GeForce GT 645M

2012

Why buy it

✅Draws 32W instead of 180W, a 148W reduction.

Trade-offs

❌Lower average FPS than GeForce GTX 1060 across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 6 GB for high-resolution textures and newer games.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 40.4 G3D/$ (Unknown MSRP vs $249 MSRP).

GeForce GTX 1060

2016

Why buy it

✅1113.5% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 40.4 vs 0 G3D/$ ($249 MSRP vs Unknown MSRP).
✅200% more VRAM for high-resolution textures and newer games (6 GB vs 2 GB).
✅GeForce GT 645M is already obsolete for modern gaming, so GeForce GTX 1060 is the less risky modern option long term.

Trade-offs

❌2016 hardware with 6 GB of VRAM already sits in legacy territory for modern games.
❌462.5% higher power demand at 180W vs 32W.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 1060 is the faster gaming card right now. In our data, it leads by 1113.5% in average FPS across 50 tracked games in our benchmark data and by 965% in PassMark G3D (10,064 vs 945), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce GTX 1060 is the safer long-term pick for 2026 and beyond. The case is simple: 6 GB vs 2 GB of VRAM, a 16nm process instead of 28nm, and a newer 2016 generation instead of 2012. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GTX 1060 makes the most sense today based on the pricing and value data we have for this matchup.
