GRID K140Q vs Quadro K420: 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
2013Why buy it
- ✅Costs $25 less on MSRP ($125 MSRP vs $150 MSRP).
- ✅Delivers 20.3% more G3D Mark for each dollar spent, at 5.8 vs 4.8 G3D/$ ($125 MSRP vs $150 MSRP).
Trade-offs
- ❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
- ❌2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
