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

GeForce FX Go 5600

2011

Why buy it

✅93.8% more VRAM for high-resolution textures and newer games (32 MB vs 16 MB).

Trade-offs

❌Lower PassMark G3D performance (18 vs 24).
❌2011 hardware with 32 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌130.8% higher power demand at 150W vs 65W.

GeForce Go 6400

2012

Why buy it

✅+33.3% higher PassMark G3D performance.
✅Draws 65W instead of 150W, a 85W reduction.
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 16 MB vs 32 MB for high-resolution textures and newer games.
❌2012 hardware with 16 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
