Radeon HD 7870M 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 7870M 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 7870M

2012

Why buy it

  • 300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
  • Draws 45W instead of 230W, a 185W reduction.

Trade-offs

  • 2012 hardware with 2 GB 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 0.6 G3D/$ (Unknown MSRP vs $2,500 MSRP).

RTXA5000-6Q

2021

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 0.6 vs 0 G3D/$ ($2,500 MSRP vs Unknown MSRP).
  • Radeon HD 7870M 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 2 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.
  • 411.1% higher power demand at 230W vs 45W.

Quick Answers

Which GPU is faster for gaming right now?
RTXA5000-6Q is the faster gaming card right now based on the synthetic data we have. It leads by 1% in PassMark G3D (1,522 vs 1,507), 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 28nm, 64 vs 0 ray-tracing units, and a newer 2021 generation instead of 2012. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
RTXA5000-6Q makes the most sense today based on the pricing and value data we have for this matchup.
