Width	2-slot	2-slot
Supplementary power connectors	1x 8-pin	1x 6-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	HBM2	GDDR4
Maximum RAM amount	8 GB	512 MB
Memory bus width	2048 Bit	256 Bit
Memory clock speed	1600 MBps	1050 MHz
Memory bandwidth	409.6 GB/s	67.2 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	1x HDMI 2.0b, 3x DisplayPort 1.4a	1x DVI, 1x VHDCI
HDMI	+	-
