Length	241 mm	no data
Width	2-slot	no data
Supplementary power connectors	2x 6-pin	no data

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	GDDR5	DDR3
Maximum RAM amount	1 GB	1 GB
Memory bus width	256 Bit	64 Bit
Memory clock speed	1000 MHz	2 GB/s
Memory bandwidth	128.0 GB/s	16 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	2x DVI, 1x HDMI, 1x DisplayPort	Portable Device Dependent
HDMI	+	-

API and SDK support
