| Supplementary power connectors | 1x 6-pin | 1x 6-pin + 1x 8-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 | GDDR5 | HBM2 |
| Maximum RAM amount | 2 GB | 16 GB |
| Memory bus width | 128 Bit | 4096 Bit |
| Memory clock speed | 1150 MHz | 1000 MHz |
| Memory bandwidth | 73.6 GB/s | 1024 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 | 6x mini-DisplayPort 1.4a |
API and SDK support
List of supported 3D and general-purpose computing APIs, including their specific versions.
