GeForce GTX TITAN X (Pascal) vs GeForce GTX 645 OEM
Summary
Reasons to consider GeForce GTX TITAN X (Pascal) |
| 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) |
| Supports Direct3D 12 Async Compute |
| Based on an outdated architecture (Nvidia Pascal), there may be no performance optimizations for current games and applications |
Reasons to consider GeForce GTX 645 OEM |
| 185 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the GeForce GTX TITAN X (Pascal) . |
| 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| Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications |
