GPU and Co-Processor Quiz

What is the purpose of a GPU?

• Manipulating computer graphics and image processing

• Printing personalised letters to customers for an advertising campaign

• Performing complex operations on small data sets

• Executing floating point calculations extremely quickly

What is the function of a GPU when used with a CPU?

• Manipulating computer graphics and image processing

• Executing floating point calculations extremely quickly

• Offloading compute-intensive parts of an application to the GPU while the remainder of the code runs on the CPU

• Printing personalised letters to customers for an advertising campaign

What is the main difference between a CPU and a GPU?

• CPUs are highly specialised, while GPUs are generic processing units

• CPUs and GPUs are designed for the same tasks

• CPUs are generic processing units, while GPUs are highly specialised

• CPUs and GPUs have the same performance characteristics

Why are GPUs so good at rendering graphics?

• They can perform a thousand floating-point operations much quicker due to parallel processing

• They are designed for complex operations on small data sets

• They are generic processing units

• They are highly specialised for scientific research

What is the purpose of a co-processor?

• To execute floating point calculations extremely quickly

• To perform complex operations on small data sets

• To manipulate computer graphics and image processing

• To improve the overall speed of the computer by executing concurrently with the main CPU

What is the advantage of having a co-processor?

• Calculation (and hence performance) is much faster

• It is more expensive and takes more power

• It is designed for parallel processing

• It is a generic processing unit

What is the disadvantage of having a co-processor?

• It is a generic processing unit

• It is more expensive and takes more power

• Calculation (and hence performance) is much faster

• It is designed for parallel processing

What is the purpose of a maths co-processor?

• To improve the overall speed of the computer by executing concurrently with the main CPU

• To carry out floating point calculation extremely quickly

• To manipulate computer graphics and image processing

• To perform complex operations on small data sets

What is the effect of using a co-processor system for complex calculations for scientific research?

• Processing is faster when using floating point arithmetic

• It is more expensive and takes more power

• No increase in speed as co-processor not suitable for task

• It is designed for parallel processing

What is the effect of using a co-processor system for printing personalised letters to customers for an advertising campaign?

• It is more expensive and takes more power

• No increase in speed as co-processor not suitable for task

• It is designed for parallel processing

• Processing is faster when using floating point arithmetic
