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

GRID M10-4Q

2016

Why buy it

✅Draws 225W instead of 375W, a 150W reduction.
✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2016 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
301.3% HIGHER MSRP
$2,805 MSRPvs$699 MSRP
❌Lower G3D Mark per dollar, at 1.1 vs 4.3 G3D/$ ($2,805 MSRP vs $699 MSRP).

Radeon HD 6990

2011

Why buy it

✅Costs $2,106 less on MSRP ($699 MSRP vs $2,805 MSRP).
✅Delivers 306.3% more G3D Mark for each dollar spent, at 4.3 vs 1.1 G3D/$ ($699 MSRP vs $2,805 MSRP).
✅GRID M10-4Q 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.
❌66.7% higher power demand at 375W vs 225W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6990 is the faster gaming card right now based on the synthetic data we have. It leads by 1.2% in PassMark G3D (3,014 vs 2,977), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon HD 6990 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That still leaves it as the safer long-term option on hardware alone.

Which GPU is the better buy today?

Radeon HD 6990 makes the most sense to buy today. It is $2,106 cheaper on MSRP at $699 vs $2,805, and it leads G3D-per-dollar by 306.3% (4.3 vs 1.1), so the value case lines up with the gaming result.
