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	GDDR3	GDDR5
Maximum RAM amount	1 GB	4 GB
Memory bus width	128 Bit	256 Bit
Memory clock speed	900 MHz	1700 MHz
Memory bandwidth	28 GB/s	217.6 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 DisplayPort 1.1	No outputs
DisplayPort count	1	no data
Dual-link DVI support	+	-
HD сomponent video output	+	-

API and SDK support
