GRID P4-2Q vs Radeon Pro 555: 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

  • Delivers 100+% more G3D Mark for each dollar spent, at 2.1 vs 0 G3D/$ ($1,500 MSRP vs Unknown MSRP).

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.
  • 200% higher power demand at 225W vs 75W.

Radeon Pro 555

2017

Why buy it

  • Draws 75W instead of 225W, a 150W reduction.
  • More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

  • 2017 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • Lower G3D Mark per dollar, at 0 vs 2.1 G3D/$ (Unknown MSRP vs $1,500 MSRP).
