CPU

8:03 AM

Central Processing Unit

• The CPU is the brains of the computer
• CPUs are just really a very powerful calculator
AMD & Intel are the two major manufacturers of CPUs
• Make is the company that produces it
• Model is the number that follows it
• The main difference between processors is the micro architecture
• Different architectures have different code names
The microarchitecture defines the properties about a processor
...

Overclocking Making a processor go faster than the rated speed
• With Overclocking, you start to have packet losses due to the processor clock not keeping up
...
5 GHz
...

- Hyper Threading is only for intel

The CPU speeds are determined by the motherboard clock crystal and the CPU clock multiplier
...

Processor Cache Used to store data close to the CPU
Processing Data:
- First, data is stored onto a hard drive because hard drives have a lot of storage but are very slow
...

- Next, the data is copied from the Hard Drive over to the RAM because the ram is smaller and can
have data processed a lot quicker then Hard Drives can, but still not as fast as processors
...

- The data is then transferred over to the small cache of the processor
...

- Finally, the cache then transfers the data to the processor to be processed
...
CPU caches usually have
about 128k of storage
...

Small Cache Vs
...

- Larger Caches are harder to find data but can store more data
...

Level 3 -> Level 2 -> Level 1 -> CPU
All of these Caches are physically on the CPU
...
Sometimes from the level 2
...
64 Bit Processing

Address Bus A type of wiring inside of processors that work to communicate with memory
...

32 Bit:
00000000000000000000000000000000
11111111111111111111111111111111
64 Bit:
0000000000000000000000000000000000000000000000000000000000000000

The architecture is made up of how many combinations of binary it can handle at once

8:30 AM

CPU Extensions Increasing the 'instructions' or a 'booster'
...
CPU
Sockets

9:20 AM

Also known as a processor socket, The connector on the motherboard that houses a CPU
and forms the electrical interface and contact with the CPU
...

• Land Grid Array (LGA): CPUs without pins, just little pads
...

When picking out a CPU, make sure the CPU socket on the motherboard is compatible with the
processor
...

• Socket AM2: Had 940 Pins, commonly used
...

• Socket AM3: Compatible with everything before
• Socket AM3+: Modern, supports 64 bit architecture, 940 pins
Intel Sockets:
• LGA 775: Oldest and most used CPU socket out there
...
(A metal lever
on the side of the CPU socket)

• Make sure your CPU is compatible with your motherboard

Cooling a CPU
Thursday, March 17, 2016

Where fans are located at:
• CPU
• Graphics Cards
• Case Fans
You want enough fans to cool your system but the more fans you have, the more noise / power you will
have
...

• 3-Prong power connectors are for system / case fans, less control
...
Or you can use 3rd
Party software that comes with your motherboard
...

Two Types of Liquid Coolants:
• Passive Liquid Cooling: The liquid passes through a mount, cooling down the system, cycles
through a radiator with the heat, and gets pumped back
...
