About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

GRID K120Q vs Radeon R3: 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 K120Q

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.
  • ❌
    150% HIGHER MSRP
    $125 MSRPvs$50 MSRP
  • ❌Lower G3D Mark per dollar, at 2.3 vs 6.3 G3D/$ ($125 MSRP vs $50 MSRP).
  • ❌350% higher power demand at 225W vs 50W.

Radeon R3

2019

Why buy it

  • ✅Costs $75 less on MSRP ($50 MSRP vs $125 MSRP).
  • ✅Delivers 167.9% more G3D Mark for each dollar spent, at 6.3 vs 2.3 G3D/$ ($50 MSRP vs $125 MSRP).
  • ✅GRID K120Q is already obsolete for modern gaming, so Radeon R3 is the less risky modern option long term.
  • ✅Draws 50W instead of 225W, a 175W reduction.

Trade-offs

  • ❌2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.

Quick Answers

Which GPU is faster for gaming right now?
Radeon R3 is the faster gaming card right now based on the synthetic data we have. It leads by 7.2% in PassMark G3D (314 vs 293), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon R3 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 14nm process instead of 28nm, and a newer 2019 generation instead of 2013. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon R3 makes the most sense to buy today. It is $75 cheaper on MSRP at $50 vs $125, and it leads G3D-per-dollar by 167.9% (6.3 vs 2.3), so the value case lines up with the gaming result.
