Radeon HD 6990 vs Radeon R7 260: 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 6990

2011

Why buy it

  • 98.2% more average FPS across 50 tracked games in our benchmark data.
  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
  • Radeon R7 260 is already obsolete for modern gaming, so Radeon HD 6990 is the less risky modern option long term.

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.
  • 541.3% HIGHER MSRP
    $699 MSRPvs$109 MSRP
  • Lower G3D Mark per dollar, at 4.3 vs 26.5 G3D/$ ($699 MSRP vs $109 MSRP).
  • 294.7% higher power demand at 375W vs 95W.
  • 82.4% longer card at 310mm vs 170mm.

Radeon R7 260

2013

Why buy it

  • Costs $590 less on MSRP ($109 MSRP vs $699 MSRP).
  • Delivers 515.3% more G3D Mark for each dollar spent, at 26.5 vs 4.3 G3D/$ ($109 MSRP vs $699 MSRP).
  • Draws 95W instead of 375W, a 280W reduction.
  • Measures 170mm instead of 310mm, a 140mm shorter card that is more SFF-friendly.

Trade-offs
