| 4 | help |
| 5 | Most x86 chips include a PCH which is responsible for handling |
| 6 | parts of the system not handled by that CPU. It supersedes the |
| 7 | northbridge / southbridge architecture that was previously used. The |
| 8 | PCH allows for higher performance since the memory functions are |
| 9 | handled in the CPU. |
