GRID K340

2013

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

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.
  • 2649.2% HIGHER MSRP
    $3,299 MSRPvs$120 MSRP
  • Lower G3D Mark per dollar, at 0.2 vs 5.4 G3D/$ ($3,299 MSRP vs $120 MSRP).
  • 200% higher power demand at 225W vs 75W.

Radeon R7 M340

2015

Why buy it

  • Costs $3,179 less on MSRP ($120 MSRP vs $3,299 MSRP).
  • Delivers 2632.2% more G3D Mark for each dollar spent, at 5.4 vs 0.2 G3D/$ ($120 MSRP vs $3,299 MSRP).
  • Draws 75W instead of 225W, a 150W reduction.

Trade-offs

  • 2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
