16
Q

x86-x64 processors

A

Can run both types of code, these are the most modern processors

17
Q

Virtualization Support

A

Run more than one OS at a time, used to have to work through software but can now work directly thru CPU

18
Q

Parallel Execution

A

Able to execute multiple commands at the same time in parallel

19
Q

Pipelining

A

Fetch
Decode
Execute
Write

Current CPUS have multiple pipelines

20
Q

Cache

A

Static RAM (SRAM) used to reduce wait states (CPU faster than RAM)

21
Q

Multithreading

A

Multiple parallel threads running at the same time, basically 2 CPUs but does not double processing power

OS and apps must be made to take advantage

22
Q

L1, L2, L3

A

L1
cache will be the smallest and fastest cache; L2 will be bigger and slower
than L1; and L3 will be the biggest and slowest cache.

23
Q

Multicore Processing

A

Multiple pipelines but share caches and RAM

Operates independently from OS, but requires optimization

24
Q

Integrated Memory Controller

A

Optimizes information flow in and out of CPU

25
Q

Integrated Graphics Processing Unit

A

Integrated Graphics, enhances performance while reducing energy use, size and cost

26
Q

Security

A

NX bit technology, CPU protects certain sections of memory, protecting essential OS files

27
Q

Selecting a CPU

A

Ensure compatibility
-Support AMD or Intel?
-What CPU socket?

28
Q

CPU Sockets

A

Intel - LGA 2066, 1200, 1700
AMD - AM4, AM5, TR4

29
Q

CPU Installation Points

A

Take care with pins and socket
Is the power supply enough
Adequate cooling
Stock or overclock

30
Q

LGA

A

Land Grid Array - CPU socket for Intel
Has pins

31
Q

PGA

A

Pin Grid Array - CPU socket for AMD
Has holes

32
Q

Passive v Active Cooling

A

Passive: Heat sink alone
Active: Heat sink with fan

33
Q

CPU Overheating, Why?

A
  1. too much thermal paste
  2. not enough thermal paste
  3. failure to connect fan power to mb

impediments to fan

lack of ventilation

34
Q

CPU Catastrophic Failure

A

Proprietary crash screens (BSOD, mac pinwheel)

Magic smoke

35
Q

Register

A

Store internal commands and data
