Length	241 mm	292 mm
Width	1-slot	2-slot
Supplementary power connectors	1x 6-pin	1x 8-pin

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	GDDR3
Maximum RAM amount	8 GB	512 MB
Memory bus width	256 Bit	256 Bit
Memory clock speed	1750 MHz	1700 MBps
Memory bandwidth	224.0 GB/s	54.4 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

No outputs
