CPU Flashcards
CPU
Central processing unit
• powerful calculator
• runs programs
• every cpu has internal features to process commands
• every CPU runs code based on a specific machine language
• CPUs use pipelines to optimize the processing of commands
How they measure capabilities of CPUs
Clock speed and cores
1 hertz(Hz)
1 megahertz(MHz)
1 gigahertz(GHz)
1 cps( cycle per second)
1 million cps
1 billion cps
CPU cores
How many lanes of information travel to and from the CPU
Multi-cores, dual-core, quad-core
Multiple cores
2 cores
4 cores
APU
Accelerated processing unit, like CPU but with graphics processing capabilities
ARMchips
Operate using a reduced instruction set computing (RISC) methodology
X86
32 bit
X64
64 bit
IA-32
Intel architecture. 32 bit
ISA
Instruction set architecture, all bit types support different ISAs
Difference between 32 and 64 bit
• major difference is the calculations per second they can perform
•Better security, data handling, and graphics with 64 bit
•almost all modern systems are backwards compatible between 64 to 32 bit
Main CPU brands
Intel and AMD
Heat sink
Helps pull heat from CPU
Fans
Move air to cool down inside of PC
Thermal Paste
•helps transfer heat from CPU to sink
•fills in tiny gaps and scratches
•best practice is a single pea sized dot
Thermal pad
Can be used instead of thermal paste, easy to install not as effective
Liquid cooling
More effective, but more complex
ZIF
Zero insertion force socket
PGA
Pin grid array, type of CPU socket, used by AMD CPUs
LGA
Land grid array, type of CPU socket
What to check when trouble shooting a nine functional CPU
Check all connections and make sure the fan, heat sink, and CPU itself are all seated properly before proceeding
