Maximum RAM amount	512 MB	System Shared
Memory bus width	128 Bit	System Shared
Memory clock speed	1254 MHz	System Shared
Memory bandwidth	80.26 GB/s	no data

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.
