Maximum RAM amount	1536 MB ×2	System Shared
Memory bus width	384 Bit ×2	System Shared
Memory clock speed	800 MHz	System Shared
Memory bandwidth	76.8 GB/s ×2	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.
