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

GeForce GTX 680MX

2012

Why buy it

✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌Lower average FPS than GeForce MX450 across 50 tracked games in our benchmark data.
❌2012 hardware with 4 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 14.9 G3D/$ (Unknown MSRP vs $250 MSRP).
❌388% higher power demand at 122W vs 25W.

GeForce MX450

2020

Why buy it

✅7.5% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 14.9 vs 0 G3D/$ ($250 MSRP vs Unknown MSRP).
✅GeForce GTX 680MX is already obsolete for modern gaming, so GeForce MX450 is the less risky modern option long term.
✅Draws 25W instead of 122W, a 97W reduction.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
