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

FirePro V7900

2011

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 2.3 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).

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.
❌275% higher power demand at 150W vs 40W.

RadeonT 660M

2023

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 150W, a 110W reduction.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 2.3 G3D/$ (Unknown MSRP vs $999 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

FirePro V7900 is the faster gaming card right now based on the synthetic data we have. It leads by 1.8% in PassMark G3D (2,261 vs 2,221), which is the best performance signal available in this matchup.

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

RadeonT 660M 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, a 6nm process instead of 40nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2011. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

FirePro V7900 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, FirePro V7900 is the easier value choice. If you care more about 1080p and some 1440p headroom, RadeonT 660M has the stronger long-term case.
