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 RX 580 2048SP: 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 16 GB for high-resolution textures and newer games.
  • No equivalent frame-generation stack like FSR Frame Generation (2023).
  • 2015 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
  • 1210% HIGHER MSRP
    $3,000 MSRPvs$229 MSRP
  • Lower G3D Mark per dollar, at 2.5 vs 33.3 G3D/$ ($3,000 MSRP vs $229 MSRP).

Radeon RX 580 2048SP

2018

Why buy it

  • Costs $2,771 less on MSRP ($229 MSRP vs $3,000 MSRP).
  • Delivers 1232% more G3D Mark for each dollar spent, at 33.3 vs 2.5 G3D/$ ($229 MSRP vs $3,000 MSRP).
  • Access to a newer frame-generation stack with FSR Frame Generation (2023).
  • 300% more VRAM for high-resolution textures and newer games (16 GB vs 4 GB).
  • GRID P40-8Q is already legacy-tier future-proofing, so Radeon RX 580 2048SP is the less risky modern option long term.

Trade-offs

  • Older hardware, 16 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 RX 580 2048SP is the faster gaming card right now based on the synthetic data we have. It leads by 1.7% in PassMark G3D (7,633 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 RX 580 2048SP is the safer long-term pick for 2026 and beyond. The case is simple: 16 GB vs 4 GB of VRAM, the newer feature stack, with FSR Upscaling / FSR 4 (2025) and FSR Frame Generation (2023), while GRID P40-8Q is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2018 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 RX 580 2048SP makes the most sense to buy today. It is $2,771 cheaper on MSRP at $229 vs $3,000, and it leads G3D-per-dollar by 1232% (33.3 vs 2.5), so the value case lines up with the gaming result.
