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 x16	PCIe 3.0 x16
Length	267 mm	no data
Width	2-slot	no data
Supplementary power connectors	2x 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	HBM2	GDDR6
Maximum RAM amount	16 GB	6 GB
Memory bus width	4096 Bit	192 Bit
Memory clock speed	1000 MHz	2000 MHz
Memory bandwidth	1.02 TB/s	384.0 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 mini-DisplayPort 1.4a	1x DVI, 1x HDMI, 3x DisplayPort
HDMI	-	+
