GeForce GT 645M vs GeForce GT 1010: 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 GT 645M

2012

Why buy it

✅300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).

Trade-offs

❌Lower average FPS than GeForce GT 1010 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.
❌Lower G3D Mark per dollar, at 0 vs 13.9 G3D/$ (Unknown MSRP vs $70 MSRP).

GeForce GT 1010

2021

Why buy it

✅13.2% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 13.9 vs 0 G3D/$ ($70 MSRP vs Unknown MSRP).
✅GeForce GT 645M is already obsolete for modern gaming, so GeForce GT 1010 is the less risky modern option long term.

Trade-offs

❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
❌Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
