GRID P40-6Q vs Radeon Vega 3 Performance Spectrum

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 P40-6Q vs Radeon Vega 3: 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 P40-6Q

2013

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 0.3 vs 0 G3D/$ ($3,000 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).

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.
  • 400% higher power demand at 225W vs 45W.

Radeon Vega 3

2021

Why buy it

  • GRID P40-6Q is already obsolete for modern gaming, so Radeon Vega 3 is the less risky modern option long term.
  • Draws 45W instead of 225W, a 180W reduction.
  • More future proof: GCN 5.1 (2018−2022) on 7nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
  • 2021 hardware with Unknown 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 0.3 G3D/$ (Unknown MSRP vs $3,000 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
GRID P40-6Q is the faster gaming card right now based on the synthetic data we have. It leads by 1.5% in PassMark G3D (905 vs 892), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon Vega 3 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 7nm process instead of 28nm, and a newer 2021 generation instead of 2013. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
GRID P40-6Q makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, GRID P40-6Q is the easier value choice. If you care more about 1080p headroom, Radeon Vega 3 has the stronger long-term case.
