GeForce 940M vs Radeon HD 7870 GHz Edition
Summary
Reasons to consider GeForce 940M |
142 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the Radeon HD 7870 GHz Edition . |
This is a much newer product, it might have better long term support. |
Supports PhysX |
Supports G-Sync |
Supports ShadowPlay (allows game streaming/recording with minimum performance penalty) |
Based on an outdated architecture (Nvidia Maxwell), there may be no performance optimizations for current games and applications |
Reasons to consider Radeon HD 7870 GHz Edition |
Higher theoretical gaming performance, based on specifications. |
Supports Direct3D 12 Async Compute |
Supports ReLive (allows game streaming/recording with minimum performance penalty) |
Supports Mantle |
Based on an outdated architecture (AMD GCN), there may be no performance optimizations for current games and applications |
HWBench recommends Radeon HD 7870 GHz Edition
Based on theoretical specifications.
