Phit
Physical Unit. An Intel QPI terminology defining units of transfer at the
physical layer. 1 Phit is equal to 20 bits in ‘full width mode’ and 10 bits in ‘half
width mode’
Processor The 64-bit, single-core or multi-core component (package)
Processor Core The term “processor core” refers to silicon die itself which can contain multiple
execution cores. Each execution core has an instruction cache, data cache, and
256-KB L2 cache. All execution cores share the L3 cache. All DC and signal
integrity specifications are measured at the processor die (pads), unless
otherwise noted.
Protected Processor
Inventory Number (PPIN)
A solution for inventory management available on Intel Xeon processor E5 v2
product families for use in server platforms. PPIN defaults to disabled and
follows an 'opt-in' model to enable it. Once PPIN is enabled, a reboot is necessary
to make it available to privileged software, such as the OS or VMM and other ring
0 applications.
RDIMM Registered Dual In-line Module
Rank A unit of DRAM corresponding four to eight devices in parallel, ignoring ECC.
These devices are usually, but not always, mounted on a single side of a
DDR3 DIMM.
SCI System Control Interrupt. Used in ACPI protocol.

SKU A processor Stock Keeping Unit (SKU) to be installed in either server or
workstation platforms. Electrical, power and thermal specifications for these
SKU’s are based on specific use condition assumptions. Server processors may
be further categorized as Efficient Performance server, workstation and HPC
SKUs. For further details on use condition assumptions, please refer to the latest
Product Release Qualification (PRQ) Report available via your Customer Quality
Engineer (CQE) contact.
SMBus System Management Bus. A two-wire interface through which simple system and
power management related devices can communicate with the rest of the
system. It is based on the principals of the operation of the I2C* two-wire serial
bus from Philips Semiconductor.
Storage Conditions A non-operational state. The processor may be installed in a platform, in a tray,
or loose. Processors may be sealed in packaging or exposed to free air. Under
these conditions, processor landings should not be connected to any supply
voltages, have any I/Os biased or receive any clocks. Upon exposure to “free air”
(that is, unsealed packaging or a device removed from packaging material) the
processor must be handled in accordance with moisture sensitivity labeling
(MSL) as indicated on the packaging material.
TAC Thermal Averaging Constant
TDP Thermal Design Power
TSOD Thermal Sensor on DIMM
UDIMM Unbuffered Dual In-line Module
Uncore The portion of the processor comprising the shared cache, IMC, HA, PCU, UBox,
and Intel QPI link interface.
Unit Interval Signaling convention that is binary and unidirectional. In this binary signaling,
one bit is sent for every edge of the forwarded clock, whether it be a rising edge
or a falling edge. If a number of edges are collected at instances t
