Form factor & compatibility

Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).

Interface	PCIe 1.0 x16	PCIe 2.0 x16
Length	no data	170 mm
Width	2-slot	1-slot
Supplementary power connectors	1x 8-pin	None

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	DDR3
Maximum RAM amount	256 MB	256 MB
Memory bus width	256 Bit	64 Bit
Memory clock speed	800 MHz	800 MBps
Memory bandwidth	51.2 GB/s	6.4 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 S-Video

2x VHDCI
