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	DDR2	GDDR5
Maximum RAM amount	512 MB	1 GB ×2
Memory bus width	64 Bit	256 Bit ×2
Memory clock speed	333 MHz	700 MHz
Memory bandwidth	5.328 GB/s	89.6 GB/s ×2

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, 1x VGA

No outputs
