Introduction
The Intel
®
Xeon
®
Processor E7-8800/4800/2800 Product Families are a next-
generation Intel
®
Xeon
®
multi-core MP family processor. The processor uses Intel
®
QuickPath Interconnect (Intel
®
QPI) technology, implementing up to four high-speed
serial point-to-point links. It is optimized for MP configurations targeted at enterprise
and technical computing applications, delivering server-class RAS and performance.
Intel Xeon Processor E7-8800/4800/2800 Product Families are multi-core processors,
based on 32-nm process technology. The processors feature Intel QuickPath
Interconnect point-to-point links capable of up to 6.4 GT/s, up to 30 MB of shared
cache, and an integrated memory controller. The processors support all the existing
Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and
Streaming SIMD Extensions 4 (SSE4). The processors support several Advanced
Technologies: Execute Disable Bit, Intel
®
64 technology, Enhanced Intel SpeedStep
®
technology, Intel
®
Virtualization technology (Intel
®
VT), and Simultaneous Multi-
Threading.

Terminology
A ‘_N’ after a signal name refers to an active low signal, indicating that a signal is in the
asserted state when driven to a low level. For example, when RESET_N is low (that is,
when RESET_N is asserted), a reset has been requested. Conversely, when TCK is high
(that is, when TCK is asserted), a test clock request has occurred.
•
Enhanced Intel SpeedStep technology
— Enhanced Intel SpeedStep technology
allows the O/S to reduce power consumption when performance is not needed.
•
Eye Definitions
— The eye at any point along the data channel is defined to be the
creation of overlapping of a large number of UI of the data signal and timing width
measured with regards to the edges of a separate clock signal at any other point.
Each differential signal pair by combining the D+ and D- signals produces a signal
eye. A _DN and _DP after a signal name refers to a differential pair.
•
FCLGA-1567
— The Intel Xeon Processor E7-8800/4800/2800 Product Families
are available in a Flip-Chip Land Grid Array (FC-LGA) package, consisting of 10
processor cores mounted on a pinned substrate with an integrated heat spreader
(IHS).
•
Functional Operation
— Refers to the normal operating conditions in which all
processor specifications, including DC, AC, system bus, signal quality, mechanical,
and thermal, are satisfied.
