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 | 6x mini-DisplayPort | 1x DisplayPort 1.4a, 2x mini-DisplayPort 1.4a |
API and SDK support
List of supported 3D and general-purpose computing APIs, including their specific versions.
