Motherboards Lesson 003: CPU Features

Processor

Directs traffic to different cores to increase the speed at which tasks can be executed.

Threading

A single stream of instructions sent by a software application to a processor.

Multithreading

The ability of an application to execute multiple instructions at the same time.

What is Multithreading also known as?

Simultaneous Multithreading (SMT) or Hyper-Threading.

What does Multithreading allow?

Multithreading allows one physical core to be treated as multiple logical processors.

What does Multithreading improve and how?

Improves efficiency by running multiple threads concurrently on shared resources.

What is the biggest limitation when it comes to Multithreading?

If a software application doesn't understand that it can tell the system to Multithreading, then the software will still send information one at a time.

Symmetric Multiprocessing (SMP)

Computers or systems that have multiple identical processors or cores, which equally share the same memory, resources, and operating system.

Multi-Core Processors

Single CPU with multiple processors inside.

Dual-Core Processor

Two cores inside a single chip.

Quad Processor

Four cores inside a single chip.

Hexa Processor

Six cores inside a single chip.

Octo Processor

Eight cores inside a single chip.

Virtualization

Creates additional computers through the use of software.

What technology does Intel use for virtualization?

Virtualization Technology (VT).

What technology does AMD use for virtualization?

AMD Virtualization (AMD-V).

Second Level Address Translation (SLAT)

Underlying hardware that Intel and AMD use in order to allow better virtual memory management.

Extended Page Table (EPT)

Second level of virtualization hardware used by Intel.

Rapid Virtualization Indexing (RVI)

Secong level of virtualization hardware used by AMD.
