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 2.0 x16	PCIe 2.0 x16
Length	305 mm	165 mm
Width	2-slot	1-slot
Supplementary power connectors	1x 6-pin + 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	GDDR5	DDR2
Maximum RAM amount	1 GB ×2	1 GB
Memory bus width	256 Bit ×2	128 Bit
Memory clock speed	1000 MHz	500 MHz
Memory bandwidth	128.0 GB/s ×2	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 mini-DisplayPort	1x DVI, 1x HDMI, 1x VGA
HDMI	-	+
