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.

CMP 40HX vs Radeon RX 580: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

CMP 40HX

2021

Why buy it

  • ✅Better long-term bet: Turing (2018−2022) on 12nm gives it a newer hardware base for upcoming games.
  • ✅Measures 229mm instead of 241mm, a 12mm shorter card that is more SFF-friendly.
  • ✅More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.

Trade-offs

  • ❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
  • ❌No equivalent frame-generation stack like FSR Frame Generation (2023).
  • ❌
    205.2% HIGHER MSRP
    $699 MSRPvs$229 MSRP
  • ❌Lower G3D Mark per dollar, at 12.5 vs 38.4 G3D/$ ($699 MSRP vs $229 MSRP).

Radeon RX 580

2017

Why buy it

  • ✅Costs $470 less on MSRP ($229 MSRP vs $699 MSRP).
  • ✅Delivers 207% more G3D Mark for each dollar spent, at 38.4 vs 12.5 G3D/$ ($229 MSRP vs $699 MSRP).
  • ✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
  • ✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

  • ❌2017 hardware with 8 GB of VRAM already sits in legacy territory for modern games.

Quick Answers

Which GPU is faster for gaming right now?
Radeon RX 580 is the faster gaming card right now based on the synthetic data we have. It leads by 0.6% in PassMark G3D (8,799 vs 8,749), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
CMP 40HX is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 14nm, 36 vs 0 ray-tracing units, and a newer 2021 generation instead of 2017. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon RX 580 makes the most sense to buy today. It is $470 cheaper on MSRP at $229 vs $699, and it leads G3D-per-dollar by 207% (38.4 vs 12.5), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon RX 580 is the easier value choice. If you care more about 1080p and some 1440p headroom, CMP 40HX has the stronger long-term case.
