HP Compaq 8100 Elite PCs with Intel Nehalem Microarchitecture

Key Chipset Features

The Intel Q57 chipset in the HP Compaq 8100 Elite systems is based on Intel

Nehalem microachitecture.

Intel Nehalem microarchitecture is a two chip solution with a processor and a

Platform Controller Hub (PCH) controlling system I/O. The memory controller is

now located within the processor. An Integrated Memory Controller (IMC) allows

for lower latency and thus better performance. In some processor models, the

graphics controller is also integrated into the processor and is known as an

Integrated Graphics Device (IGD).

The previous Intel Core microarchitecture is a three chip solution with a processor, a

Graphics and Memory Controller Hub (GMCH), and an I/O Controller Hub (ICH).

The memory controller and graphics controller are external to the processor.

The change in the chipset layout is transparent to the user. Functionality of the

major I/O subcomponents remains the same. In certain cases, there will be a

performance gain.
