Topic 2D. Install and Configure CPUs
Why can cache improve performance? - answer A CPU tends to repeat the same
routines and access the same data over and over again. If these routines are stored in
fast cache RAM, they can be accessed more quickly than instructions and data stored
in system memory.
A workstation has a multi-socket motherboard but only a single LGA 1150 socket is
populated. The installed CPU is a Xeon E3-1220. You have a Xeon E3-1231 CPU in
store that also uses the LGA 1150. Should this be used to enable symmetric
multiprocessing and upgrade system performance? - answer No. The CPU models
must be identical. If the CPUs are not identical, the system is unlikely to boot. Even if
the system boots, it is not likely to operate reliably.
You are specifying a computer for use as a software development workstation. This will
be required to run multiple virtual machines (VMs). Can any x64-compatible CPU with
sufficient clock speed be used? - answerNo. You must verify that the CPU model
supports virtualization extensions.
What must you check when inserting a PGA form factor CPU? - answer You must
check that pin 1 is aligned properly and that the pins on the package are aligned with
the holes in the socket. Otherwise, you risk damaging the pins when the locking lever is
secured.
x86 - answerThe x86 CPU Architecture refers to the way a computer processes
information. The x86 instruction set defines a CPU as IBM PC compatible. x86 PC
processors are designed and manufactured by Intel and Advanced Micro Devices
(AMD).
Intel - answerIntel processors were used in the first IBM PCs, and the company's CPUs
and chipsets continue to dominate the PC and laptop market.
Advanced Micro Devices (AMD) - answerCPU manufacturer providing healthy
competition for Intel. AMD chips such as the K6 or Athlon 64 and latterly the Ryzen
have been very popular with computer manufacturers and have often out-performed
their Intel equivalents.
Advanced RISC Machines (ARM) - answerDesigner of CPU and chipset architectures
widely used in mobile devices. RISC stands for reduced instruction set computing. RISC
microarchitectures use a small number of simple instructions that can be performed as
a single operation. This contrasts with complex (CISC) microarchitectures, which use a
large set of more powerful instructions that can take more than one operation to
complete.
