GeForce 9400 GT PCI vs Radeon HD 7870 GHz Edition
Summary
Reasons to consider GeForce 9400 GT PCI |
| 125 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 . |
| Based on an outdated architecture (Nvidia Tesla), there are no performance optimizations for current games and applications |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 Radeon HD 7870 GHz Edition |
| This is a much newer product, it might have better long term support. |
| 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| Based on an outdated architecture (AMD GCN), there may be no performance optimizations for current games and applications |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.
