Introduction
The Intel
®
Core™2 Duo processor E8000 and E7000 series is based on the Enhanced
Intel
®
Core
™
microarchitecture. The Intel Enhanced Core
™
microarchitecture combines
the performance of previous generation Desktop products with the power efficiencies of
a low-power microarchitecture to enable smaller, quieter systems. The Intel
®
Core™2
Duo processor E8000 and E7000 series are 64-bit processors that maintain
compatibility with IA-32 software.
Note:
In this document, the Intel
®
Core™2 Duo processor E8000 and E7000 series may be
referred to as "the processor."
Note:
In this document, unless otherwise specified, the Intel
®
Core™2 Duo processor E8000
series refers to the Intel
®
Core™2 Duo processors E8600, E8500, E8400, E8300,
E8200, and E8190.
Note:
In this document, unless otherwise specified, the Intel
®
Core™2 Duo processor E7000
series refers to the Intel
®
Core™2 Duo processors E7500, E7400, E7300 and E7200.
The processors use Flip-Chip Land Grid Array (FC-LGA8) package technology, and plugs
into a 775-land surface mount, Land Grid Array (LGA) socket, referred to as the
LGA775 socket.
The processors are based on 45 nm process technology. The processors feature the
Intel
®
Advanced Smart Cache, a shared multi-core optimized cache that significantly
reduces latency to frequently used data. The Intel
®
Core™2 Duo processor E8000
series features a 1333 MHz front side bus (FSB) and 6 MB of L2 cache. The Intel
®
Core™2 Duo processor E7000 series features a 1333 MHz and 1066 MHz front side bus
(FSB) and 3 MB of L2 cache. The processors support all the existing Streaming SIMD
Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3), Supplemental Streaming
SIMD Extension 3 (SSSE3), and the Streaming SIMD Extensions 4.1 (SSE4.1). The
processors support several Advanced Technologies: Execute Disable Bit, Intel
®
64
architecture, and Enhanced Intel SpeedStep
®
Technology. The Intel
®
Core™2 Duo
processor E8600, E8500, E8400, E8300, and E8200 support Intel
®
Trusted Execution
Technology (Intel
®
TXT) and Intel
®
Virtualization Technology (Intel
®
VT).
The processor's front side bus (FSB) use a split-transaction, deferred reply protocol.
The FSB uses Source-Synchronous Transfer of address and data to improve
performance by transferring data four times per bus clock (4X data transfer rate).
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.
