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

✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 512 MB vs 2 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.
❌
26.3% HIGHER MSRP
$125 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 5.8 vs 7.3 G3D/$ ($125 MSRP vs $99 MSRP).
❌58.9% longer card at 267mm vs 168mm.

Radeon HD 6670

2010

Why buy it

✅Costs $26 less on MSRP ($99 MSRP vs $125 MSRP).
✅Delivers 25.7% more G3D Mark for each dollar spent, at 7.3 vs 5.8 G3D/$ ($99 MSRP vs $125 MSRP).
✅300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
✅Measures 168mm instead of 267mm, a 99mm shorter card that is more SFF-friendly.

❌2010 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

GRID K140Q is the faster gaming card right now based on the synthetic data we have. It leads by 0.4% in PassMark G3D (728 vs 725), which is the best performance signal available in this matchup.

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

GRID K140Q is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2013 generation instead of 2010. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon HD 6670 makes the most sense to buy today. It is $26 cheaper on MSRP at $99 vs $125, and it leads G3D-per-dollar by 25.7% (7.3 vs 5.8), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 6670 is the easier value choice. If you care more about 1080p and some 1440p headroom, GRID K140Q has the stronger long-term case.
