GRID P40-8Q vs Radeon RX 780 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 P40-8Q vs Radeon RX 780: 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

  • No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
  • 2015 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
  • 501.2% HIGHER MSRP
    $3,000 MSRPvs$499 MSRP
  • Lower G3D Mark per dollar, at 2.5 vs 15.3 G3D/$ ($3,000 MSRP vs $499 MSRP).
  • 25% higher power demand at 225W vs 180W.

Radeon RX 780

2024

Why buy it

  • Costs $2,501 less on MSRP ($499 MSRP vs $3,000 MSRP).
  • Delivers 513.3% more G3D Mark for each dollar spent, at 15.3 vs 2.5 G3D/$ ($499 MSRP vs $3,000 MSRP).
  • Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
  • Better long-term bet: RDNA 3.0 (2022−2026) on 5nm gives it a newer hardware base for upcoming games.
  • Draws 180W instead of 225W, a 45W reduction.

Trade-offs

  • Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

Which GPU is faster for gaming right now?
Radeon RX 780 is the faster gaming card right now based on the synthetic data we have. It leads by 2% in PassMark G3D (7,658 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 780 is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GRID P40-8Q is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 5nm process instead of 28nm, 60 vs 0 ray-tracing units, and a newer 2024 generation instead of 2015. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon RX 780 makes the most sense to buy today. It is $2,501 cheaper on MSRP at $499 vs $3,000, and it leads G3D-per-dollar by 513.3% (15.3 vs 2.5), so the value case lines up with the gaming result.
