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 3.0 x16	PCI
Length	267 mm	145 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.

Maximum RAM amount	2x 12 GB	512 MB
Memory bus width	2x 384 Bit	64 Bit
Memory clock speed	5012 MHz	333 MHz
Memory bandwidth	2x 240.6 GB/s	5.328 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	1x DVI, 1x HDMI
HDMI	-	+
