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 2.0 x16 | PCIe 3.0 x16 |
| Length | 203 mm | 241 mm |
| Width | 2-slot | 2-slot |
| Supplementary power connectors | 1x 6-pin | 1x 6-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 | GDDR5 |
| Maximum RAM amount | 512 MB | 4 GB |
| Memory bus width | 128 Bit | 256 Bit |
| Memory clock speed | 800 MHz | 1650 MHz |
| Memory bandwidth | 51.2 GB/s | 211.2 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 | 2x DVI, 1x S-Video | 1x HDMI, 3x DisplayPort |
| HDMI | - | + |
API and SDK support
