ITPEC IP April 2024 Question 12
Which of the following is an appropriate explanation of GPU?
Explanation
A processing unit used instead of the CPU to speed up image processing such as 3D graphics — that is a GPU, a Graphics Processing Unit.
A GPU has a very large number of simple arithmetic units that apply the same operation to many pixels or vertices at once. It takes over graphics work from the CPU, and the same parallel power is now used for machine learning and scientific computing.
Answer (d)
Why not others:
- •(a) — a count of instructions executed per second is a CPU performance index such as MIPS (millions of instructions per second)
- •(b) — the signal that synchronizes the CPU's operations is the clock, and its rate is the clock frequency
- •(c) — fast storage between the CPU and main memory is cache memory
Key rule: A GPU accelerates work that is the same calculation on large amounts of data; the CPU stays in charge of general, sequential processing.
