GeForce 615 vs GeForce 820M
Summary
Reasons to consider GeForce 615 |
| Supports PhysX |
| Based on an outdated architecture (Nvidia Fermi), there are no performance optimizations for current games and applications |
Reasons to consider GeForce 820M |
| 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| Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications |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 820M
Based on theoretical specifications.
