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 | HBM |
| Maximum RAM amount | 6 GB | 4 GB |
| Memory bus width | 384 Bit | 4096 Bit |
| Memory clock speed | 1300 MHz | 500 MHz |
| Memory bandwidth | 249.6 GB/s | 512.0 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 | No outputs | 1x HDMI 1.4a, 3x mini-DisplayPort 1.2 |
| HDMI | - | + |
