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	PCIe 3.0 x16
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	GDDR5	HBM2
Maximum RAM amount	8 GB	8 GB
Memory bus width	256 Bit	2048 Bit
Memory clock speed	1695 MHz	800 MHz
Memory bandwidth	217.0 GB/s	409.6 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 HDMI, 3x DisplayPort
HDMI	-	+

API and SDK support

List of supported 3D and general-purpose computing APIs, including their specific versions.
