GeForce GT 120 Mac Edition vs GeForce GT 640
Summary
Reasons to consider GeForce GT 120 Mac Edition |
| Based on an outdated architecture (Nvidia Tesla), there are no performance optimizations for current games and applications |
| PhysX support, however PhysX performance on newest games may be poor |
Reasons to consider GeForce GT 640 |
| This is a much newer product, it might have better long term support. |
| Higher theoretical gaming performance, based on specifications. |
| Supports PhysX |
| Supports G-Sync |
| Supports ShadowPlay (allows game streaming/recording with minimum performance penalty) |
| Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications |
HWBench recommends GeForce GT 640
Based on theoretical specifications.
