Connectivity and outputs
This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.
| Display Connectors | 1x DVI, 1x HDMI, 1x DisplayPort | 2x DVI, 1x mini-HDMI |
| HDMI | + | + |

Pros & cons summary
| Performance score | 2.63 | 2.64 |
| Recency | 5 June 2012 | 11 October 2010 |
| Maximum RAM amount | 2 GB | 1 GB |
| Chip lithography | 28 nm | 40 nm |
| Power consumption (TDP) | 65 Watt | 150 Watt |
GT 640 has an age advantage of 1 year, a 100% higher maximum VRAM amount, a 42.9% more advanced lithography process, and 130.8% lower power consumption.
GTX 460 OEM, on the other hand, has a 0.4% higher aggregate performance score.
Given the minimal performance differences, no clear winner can be declared between GeForce GT 640 and GeForce GTX 460 OEM.
