About the Cache Size Calculator
Cache data capacity follows from line bytes, sets and ways.
Formula
Cache size equals line size times sets times associativity.
Example
64-byte lines, 1,024 sets and 8 ways equal 512 KiB.
Notes
This capacity excludes tags, metadata, replacement state and implementation overhead.
