GeForce 315M

2015

Why buy it

✅0.7% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌150% higher power demand at 75W vs 30W.

GeForce GT 320M

2017

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
✅Draws 30W instead of 75W, a 45W reduction.
✅More future proof: Pascal (2016−2021) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce 315M across 50 tracked games in our benchmark data.
