GRID K140Q vs Radeon HD 6800M: Pros, Cons & Final Verdict

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

GRID K140Q

2013

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 5.8 vs 0 G3D/$ ($125 MSRP vs Unknown MSRP).
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌49% higher power demand at 225W vs 151W.

Radeon HD 6800M

2010

Why buy it

✅Draws 151W instead of 225W, a 74W reduction.

Trade-offs

❌2010 hardware with 512 MB 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 5.8 G3D/$ (Unknown MSRP vs $125 MSRP).
