GeForce GT 555M vs GRID K340: Pros, Cons & Final Verdict

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

GeForce GT 555M

2013

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
✅Draws 50W instead of 225W, a 175W reduction.
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2013 hardware with 1 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 0.2 G3D/$ (Unknown MSRP vs $3,299 MSRP).

GRID K340

2013

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 0.2 vs 0 G3D/$ ($3,299 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌350% higher power demand at 225W vs 50W.
