CPU Architectures and Socket Types Flashcards

ARM instruction set architecture

Reduced Instruction Set Computing used in mobile and embedded devices

BGA socket type

Ball Grid Array permanently soldered to the motherboard

CISC vs RISC

CISC has complex instructions while RISC has simple fixed-length instructions

CPU core

Independent processing unit within a CPU capable of executing tasks

CPU multiplier

Factor that multiplies the base clock to determine the CPU frequency

CPU thread

Virtualized division of a core that handles instruction streams concurrently

Difference between LGA and PGA

LGA has pins on the socket while PGA has pins on the CPU

Hyper-threading

Intel technology allowing a single core to handle two threads simultaneously

L1 cache

Smallest and fastest cache located closest to the CPU core

L2 cache

Medium size cache that balances speed and capacity

L3 cache

Largest cache shared among multiple cores

LGA socket type

Land Grid Array where pins are on the motherboard

Overclocking

Running a CPU at a higher frequency than its base clock

PGA socket type

Pin Grid Array where pins are on the CPU

Turbo Boost

Technology that temporarily increases CPU frequency above base clock

x86 instruction set architecture

Complex Instruction Set Computing used by Intel and AMD
