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 4.0 x8	PCIe 3.0 x16
Length	164 mm	no data
Width	2-slot	no data
Supplementary power connectors	None	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	LPDDR4X	GDDR6
Maximum RAM amount	4 GB	2 GB
Memory bus width	128 Bit	64 Bit
Memory clock speed	2133 MHz	10 GB/s
Memory bandwidth	68.26 GB/s	80 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, 3x DisplayPort	No outputs
HDMI	+	-
