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 P40-8Q vs Radeon Pro 580X: 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 P40-8Q

2015

Why buy it

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

Trade-offs

  • ❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
  • ❌2015 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
  • ❌
    400% HIGHER MSRP
    $3,000 MSRPvs$600 MSRP
  • ❌Lower G3D Mark per dollar, at 2.5 vs 12.6 G3D/$ ($3,000 MSRP vs $600 MSRP).
  • ❌50% higher power demand at 225W vs 150W.

Radeon Pro 580X

2019

Why buy it

  • ✅Costs $2,400 less on MSRP ($600 MSRP vs $3,000 MSRP).
  • ✅Delivers 402.2% more G3D Mark for each dollar spent, at 12.6 vs 2.5 G3D/$ ($600 MSRP vs $3,000 MSRP).
  • ✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).
  • ✅GRID P40-8Q is already legacy-tier future-proofing, so Radeon Pro 580X is the less risky modern option long term.
  • ✅Draws 150W instead of 225W, a 75W reduction.

Trade-offs

  • ❌Older hardware, 8 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.

Quick Answers

Which GPU is faster for gaming right now?
Radeon Pro 580X is the faster gaming card right now based on the synthetic data we have. It leads by 0.4% in PassMark G3D (7,540 vs 7,507), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon Pro 580X is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 4 GB of VRAM, 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 2015. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Radeon Pro 580X makes the most sense to buy today. It is $2,400 cheaper on MSRP at $600 vs $3,000, and it leads G3D-per-dollar by 402.2% (12.6 vs 2.5), so the value case lines up with the gaming result.
