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	AGP 2x
Length	267 mm	no data
Width	2-slot	IGP
Supplementary power connectors	1x 6-pin + 1x 8-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	System Shared
Maximum RAM amount	5 GB	System Shared
Memory bus width	320 Bit	System Shared
Memory clock speed	1300 MHz	System Shared
Memory bandwidth	208.0 GB/s	no data

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.
