GRID P4-2Q vs Radeon HD 7790: 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 P4-2Q

2015

Why buy it

  • More future proof: Maxwell 2.0 (2014−2019) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 906.7% HIGHER MSRP
    $1,500 MSRPvs$149 MSRP
  • Lower G3D Mark per dollar, at 2.1 vs 20.7 G3D/$ ($1,500 MSRP vs $149 MSRP).
  • 164.7% higher power demand at 225W vs 85W.

Radeon HD 7790

2013

Why buy it

  • Costs $1,351 less on MSRP ($149 MSRP vs $1,500 MSRP).
  • Delivers 883.8% more G3D Mark for each dollar spent, at 20.7 vs 2.1 G3D/$ ($149 MSRP vs $1,500 MSRP).
  • Draws 85W instead of 225W, a 140W reduction.

Trade-offs

  • 2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
