Q66 / 100
What is "memory bandwidth," and why does it matter for system performance?
Correct! Well done.
Incorrect.
The correct answer is A) The rate at which data can be read from or written to memory, typically measured in bytes per second; higher bandwidth allows more data to move between CPU and memory in a given time, reducing bottlenecks for data-intensive tasks
A
Correct Answer
The rate at which data can be read from or written to memory, typically measured in bytes per second; higher bandwidth allows more data to move between CPU and memory in a given time, reducing bottlenecks for data-intensive tasks
Explanation
For workloads that move large amounts of data (e.g., video processing, scientific computing), memory bandwidth can be a limiting factor even if the CPU itself is fast, since the CPU may stall waiting for data.
