VRAM capacity and type

Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.

Memory type	DDR3	GDDR5
Maximum RAM amount	2 GB	2 GB
Memory bus width	128 Bit	64 Bit
Memory clock speed	1800 MBps	1500 MHz
Memory bandwidth	28.8 GB/s	48 GB/s

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 1.4a, 1x VGA	No outputs
HDMI	+	-
