| Maximum RAM amount | 512 MB ×2 | 1 GB |
| Memory bus width | 256 Bit ×2 | 128 Bit |
| Memory clock speed | 600 MHz | 500 MHz |
| Memory bandwidth | 38.4 GB/s ×2 | 16 GB/s |
Connectivity and outputs
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 | 2x DVI, 1x S-Video | 1x DVI, 1x HDMI, 1x VGA |
| HDMI | - | + |
