CPU Performance Quiz

Test your understanding of clock speed, cache, and cores

Question 1 of 8

What is clock speed measured in?

Megabytes (MB) Watts (W) Hertz (Hz) / Gigahertz (GHz) Bits per second (bps)

Question 2 of 8

What is a disadvantage of increasing clock speed?

The CPU processes fewer instructions The CPU generates more heat and uses more power Programs cannot run on the CPU The cache becomes smaller

Question 3 of 8

Which level of cache is the fastest but smallest?

L1 Cache L2 Cache L3 Cache RAM

Question 4 of 8

What is a "cache hit"?

When the cache memory is full When the cache is damaged When data must be fetched from RAM When the required data is found in the cache

Question 5 of 8

What is a CPU core?

The outer casing of the CPU A type of cache memory An independent processing unit that can execute instructions The main power supply for the CPU

Question 6 of 8

When does having more CPU cores NOT improve performance?

When running video editing software When software is single-threaded and cannot use multiple cores When multitasking with many programs When rendering 3D graphics

Question 7 of 8

Scenario: A video editor is choosing between two laptops:
Laptop A: 4.0 GHz dual-core, 4MB cache
Laptop B: 3.2 GHz octa-core, 16MB cache

Which laptop would be better for video editing, and why?

Laptop A - higher clock speed means faster rendering Laptop B - video editing uses multiple cores for parallel processing Laptop A - dual-core is enough for any task Both would perform exactly the same

Question 8 of 8

Why is larger cache expensive even though it's "just memory"?

It uses more electricity It makes the CPU run slower It requires special cooling It takes up space on the CPU chip and must be extremely fast
