SLI vs. CrossFire
SLI Summary
Contents
Below you can find quick reference tables on SLI. As you can see SLI mode can also be used to increase the
maximum resolution your video card can generate.
| Mode | Supported Video Cards | Maximum Resolution | Maximum SLI AA |
| SLI | GeForce 6600 and upAll GeForce 7All GeForce 8 | 2560×1600 | 16x |
| Quad SLI | GeForce 7950 GX2GeForce 9800 GX2 | 2560×1600 | 32x |
| Three-way SLI | GeForce 8800 GTXGeForce 8800 Ultra | 2560×1600 | To be confirmed |

Below you can find a list with all chipsets that support SLI. Under “PCI Express Mode” we listed what is the real transfer rate of the x16 PCI Express slots when SLI mode is enabled. Keep in mind that when SLI mode is disabled and you have only one video card installed the main PCI Express x16 slot will always work at x16.
