| Memory type | System Shared | DDR3 |
| Maximum RAM amount | System Shared | 512 MB |
| Memory bus width | System Shared | 64 Bit |
| Memory clock speed | System Shared | 1066 MHz |
| Memory bandwidth | no data | 8.528 GB/s |
Video outputs and ports
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
| Display Connectors | No outputs | No outputs |
