Introduction

This whitepaper discusses the HP implementation of new Intel microarchitecture

codenamed Nehalem.

HP is a leading edge technology company offering the latest and greatest

computing technology to our customers. Intel Nehalem-based microarchitecture will

be available to Enterprise business-class machines starting with the HP Compaq

810 0 Elite.

What’s New

HP Compaq 8100 Elite systems are based on Intel

Nehalem microarchitecture which is a significant

departure from previous generation HP Elite systems

based on Intel Core 2 microarchitecture. Both the

processor and the chipset have been redesigned to

deliver better performance and system responsiveness.

HP Compaq 8100 Elite systems are shipping with Intel

C o re i 7, i5, and i3 processors coupled with the Intel

Q57 Express chipset.

Note: The Intel processor naming convention can be a

little confusing. The Intel Core 2 microarchitecture

(Core 2 Duo, Core 2 Quad) is the older technology. The Intel Core

microarchitecture (Core i7, Core i5, Core i3) is the newer technology.

Key Processor Features The Intel Core i7, i5, and i3 processors have several key features to enhance system performance. Most notable is the architecture has changed and they now include an Integrated Memory Controller (IMC) making them monolithic processors. The IMC and the multiple processor cores are connected by the new QuickPath Interconnect (QPI). Key Feature Integrated Memory Controller (IMC) IMC offers high bandwidth and low latency for memory I/O leading to faster memory read and write cycles.

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.
