Radeon HD 6790 vs RTXA5000-6Q 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.

Radeon HD 6790 vs RTXA5000-6Q: Pros, Cons & Final Verdict

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

Radeon HD 6790

2011

Why buy it

  • Costs $2,351 less on MSRP ($149 MSRP vs $2,500 MSRP).
  • Delivers 1627.5% more G3D Mark for each dollar spent, at 10.5 vs 0.6 G3D/$ ($149 MSRP vs $2,500 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • Draws 150W instead of 230W, a 80W reduction.

Trade-offs

  • 2011 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

RTXA5000-6Q

2021

Why buy it

  • Radeon HD 6790 is already obsolete for modern gaming, so RTXA5000-6Q is the less risky modern option long term.
  • More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
  • Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • 1577.9% HIGHER MSRP
    $2,500 MSRPvs$149 MSRP
  • Lower G3D Mark per dollar, at 0.6 vs 10.5 G3D/$ ($2,500 MSRP vs $149 MSRP).
  • 53.3% higher power demand at 230W vs 150W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon HD 6790 is the faster gaming card right now based on the synthetic data we have. It leads by 3% in PassMark G3D (1,567 vs 1,522), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
RTXA5000-6Q is the safer long-term pick for 2026 and beyond. The case is simple: a 8nm process instead of 40nm, 64 vs 0 ray-tracing units, and a newer 2021 generation instead of 2011. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon HD 6790 makes the most sense to buy today. It is $2,351 cheaper on MSRP at $149 vs $2,500, and it leads G3D-per-dollar by 1627.5% (10.5 vs 0.6), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon HD 6790 is the easier value choice. If you care more about 1080p and some 1440p headroom, RTXA5000-6Q has the stronger long-term case.
