Factors affecting CPU performance

Clock speed is measures in

• bytes
• bits
• time
• hertz

A computer measured in 1 hertz can do how many things a second

• 100
• 1
• 2
• 1000

You can overclock a computer to make the processor run faster which increases the processing power.

• true
• FALSE

Which one of these is not true when overclocking

• it will speed up your computer
• it will make your computer run cooler
• it may make your computer unstable
• your computer may need more volts

The rate of the fetch execute cycle depends on the clock speed.

• true
• FALSE

A 2GHz Processor can process:

• 2,000,000 instructions per second

• 2,000,000,000 instructions per second

• 20,000,000 instructions per second

• 200,000 instructions per second

A PC uses cache memory to help improve performance. Which of the following statements about cache memory is true?

• Level 3 cache is closest to the CPU

• Cache is part of main memory

• Level 1 cache is closest to the CPU

• Cache memory is cheaper than "normal" memory

Which of the factors below can significantly impact the performance of a CPU? (choose as many as are appropriate)

• Clock Speed

• Cache Size

• Number of cores

• SSD (Solid State Drive)

Which of the following statements are true? (select as many as appropriate)

• A dual-core CPU can run through the Fetch Execute Cycle, four times per second

• Overclocking is a safe way of improving CPU performance

• A quad-core CPU can carry out more Fetch Execute Cycles per second than a dual core CPU

• Overclocking can improve CPU performance

How does clock speed affect CPU performance?

• Faster clock speed, means more instructions per second can be processed by the CPU

• Faster clock speed, means more instructions can be carried out at the same time

• Faster clock speed means the cache will run faster

• Faster clock speed means more storage is available for instructions, data and programs.
