P102-100 vs Radeon HD 6990M 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.

P102-100 vs Radeon HD 6990M: Pros, Cons & Final Verdict

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

P102-100

2018

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 5.5 vs 0 G3D/$ ($600 MSRP vs Unknown MSRP).
  • Radeon HD 6990M is already obsolete for modern gaming, so P102-100 is the less risky modern option long term.
  • More future proof: Pascal (2016−2021) on 16nm with a newer platform for upcoming games.

Trade-offs

  • 2018 hardware with 2 GB of VRAM already sits in legacy territory for modern games.
  • 150% higher power demand at 250W vs 100W.

Radeon HD 6990M

2011

Why buy it

  • Draws 100W instead of 250W, a 150W reduction.

Trade-offs

  • 2011 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 5.5 G3D/$ (Unknown MSRP vs $600 MSRP).
