Multicore and Cooling Processors

Question 1

What do multicore processors have that single cores don’t?

Answer 1

More than one processor on the same integrated circuit.

Question 2

In some core architechtures, what do their CPUs have?

Answer 2

Seperate L2 and L3 caches.

In others however, the cache is sharedamongst others for better performance and resource allocation.

Question 3

What is shared between all the different processors?

Answer 3

RAM, as they are ultimately still all on the same chip.

Question 4

What is a multicore processor recommended for?

Answer 4

Applications such as Video Editing, Gaming and Photo Manipulation.

Question 5

What is the benefit of having so many processors on the same integaretd circuit?

Answer 5

They have a very fast connection.

They execute intsructions muhc faster.

Question 6

Whyis having a multi-core processor better than multiple single cores?

Answer 6

Because they produce less heat overall.

This is because Multicore conserve more power and produce less heat.

Question 7

What is a GPU?

Answer 7

A chip that performs rapid mathematical equations in order to render graphics.

Question 8

What is sometimes integrated into the CPU?

Answer 8

The graphics processing unit. GPU.

Question 9

What are the benefits and trade off on intergaretd GPUs?

Answer 9

The benefit is less heat and less cost.

The tradeoff is less performance. They are not good in high spec systems.

Question 10

What ahve some CPUs been built with?

Answer 10

The NX bit.

Question 11

What is the NX bit?

Answer 11

A feature, that when supported and enabled in the operating system, can protect areas of memory that contain operating system files from malicious atatcks by malware.

Question 12

What are the five relevant cooling mechanisms?

Answer 12

Case Fan.
CPU Heat Sink.
CPU Fan.
Graphics Card Cooling System.
Water Cooling System.

Question 13

What are the features of case fans?

Answer 13

Increaases the air flow in the case, allowing for cooling.

Some blow out hot air, while others blow in cool air.

Question 14

What are the features of CPU heatsinks?

Answer 14

Draws heataway from the CPU.
Installed on top of the CPU.
Dissipates heat into the air.
It cools passively.
Thermal paste between the CPU and heatsink aids the heat transfer.

Question 15

What are the features of CPU fans?

Answer 15

Installed on top of CPUs.

Active cooling method.

Question 16

What are the features of GPU fans?

Answer 16

Video cards come with them installed.

These are dedicated to these specific components.

Question 17

What are the features of watre cooling systems?

Answer 17

A metal plate is placed over the processor that water is then pumped onto.
The water is pumped to a radiator to disperse then heat, then recirculated.
Used in high heat systems as an alternative to fans.
