Introduction

1 Introduction
The Intel
processor E6000 and E4000 series combine the performance of the previous generation
of desktop products with the power efficiencies of a low-power microarchitecture to
enable smaller, quieter systems. These processors are 64-bit processors that maintain
compatibility with IA-32 software.
The Intel
processor E6000 and E4000 series use Flip-Chip Land Grid Array (FC-LGA6) package
technology, and plugs into a 775-land surface mount, Land Grid Array (LGA) socket,
referred to as the LGA775 socket.
Note: In this document, unless otherwise specified, the Intel
processor E6000 series refers to Intel
E6550, E6540, E6700, E6600, E6420, E6400, E6320, and E6300. The Intel
Duo desktop processor E4000 series refers to Intel
E4700, E4600, E4500, E4400, and E4300.

Execution Technology (Intel
The processor's front side bus (FSB) uses a split-transaction, deferred reply protocol
like the Intel
of address and data to improve performance by transferring data four times per bus
clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address
bus can deliver addresses two times per bus clock and is referred to as a "double-
clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus
provide a data bus bandwidth of up to 10.7 GB/s.
Intel has enabled support components for the processor including heatsink, heatsink
retention mechanism, and socket. Manufacturability is a high priority; hence,
mechanical assembly may be completed from the top of the baseboard and should not
require any special tooling.
The processor includes an address bus power-down capability which removes power
from the address and data signals when the FSB is not in use. This feature is always
enabled on the processor.
