GeForce GT 340 vs Radeon HD 6670: 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 340

2014

Why buy it

  • Draws 64W instead of 250W, a 186W reduction.
  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Lower average FPS than Radeon HD 6670 across 50 tracked games in our benchmark data.
  • Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
  • 2014 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 6670

2010

Why buy it

  • 89.1% more average FPS across 50 tracked games in our benchmark data.
  • Costs $1 less on MSRP ($99 MSRP vs $100 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).

Trade-offs

  • 2010 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 290.6% higher power demand at 250W vs 64W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon HD 6670 is the faster gaming card right now. In our data, it leads by 89.1% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 340 instead at 738 vs 725, so for this question the real-game FPS result matters more than the synthetic split.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GT 340 is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2014 generation instead of 2010. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
GeForce GT 340 makes the most sense to buy today. It is $1 more expensive on MSRP at $100 vs $99, and it leads G3D-per-dollar by 0.8% (7.4 vs 7.3), which is enough to swing the recommendation its way. Radeon HD 6670 still makes more sense if max raw gaming performance matters more than value.
