5.  The instruction decoder has three decoder units that can
decode one simple instruction per cycle per unit.
 The other decoder unit can decode one instruction every
cycle, either simple instruction or complex instruction made
up of several micro-ops.
 Instructions made up of more than four micro-ops are
delivered from the MSROM.
 Up to four micro-ops can be delivered each cycle to the
instruction decoder queue (IDQ).
 The IDQ delivers micro-op stream to the
allocation/renaming stage of the pipeline.

6.  It is an higher turbo boosting frequency which
increases its voltage and frequency without violating
the power.
 The i7 processor is idle for its power gating, as the
power gating aims to cut the leakage current as well,
thereby further reducing the power consumption of the
idle core.

consumption, and the estimated power consumption.
 Normally, the Core i7 processor can operate at
frequencies between 1.5 GHz and 3.2 GHz (the
maximum non-Turbo Boost frequency or the base
frequency) in frequency steps of 133.33 MHz. With
Turbo Boost enabled, the processor can increase the
frequency of cores two further levels to voltage, and
thermal envelope.

8.  Intel representatives state that Core i7 is meant to help
consumers decide which processor to purchase as the
ner Nehalem-based products are released in the future.
 The name continues the use of the Intel Core brand.
Core i7, first assembled in Costa Rica, was officially
launched on November 17, 2008[11]
 And is manufactured in Arizona, New Mexico and
Oregon.

15.  Nearly all modern CPUs represent numbers in
binary form; with each digit being represented by some
two-valued physical quantity such as a "high" or "low"
voltage related to number representation is the size and
precision of numbers that a CPU can represent.

16. 16

17.  In the case of a binary CPU, a bit refers to one significant
place in the numbers a CPU deals with.
 The number of bits (or numeral places) a CPU uses to
represent numbers is often called "word size", "bit
width", "data path width", or "integer precision" when
dealing with strictly integer numbers (as opposed to
floating point).
 This number differs between architectures, and often
within different parts of the very same CPU
17

18.  The performance or speed of a processor depends on
e.g. the clock rate and the Instructions per Clock (IPC),
which together are the factors for the Instructions Per
Second(IPS) that the CPU can perform.
 Many reported IPS values have represented "peak"
execution rates on artificial instruction sequences with
few branches, whereas realistic workloads consist of a
mix of instructions and applications, some of which
take longer to execute than others.
