Performance
Cache
Small, ultra-fast memory on the CPU that stores frequently used data to avoid slow RAM access.
Also known as:
L1 Cache
L2 Cache
L3 Cache
CPU Cache
Full Definition & Technical Explanation
Cache is on-die memory faster than RAM. CPUs show L1 Cache (fastest, per core), L2 Cache (per core or cluster), and L3 Cache (shared, e.g., 30 MB).
Bigger caches reduce slowdowns from memory waits and measurably improve gaming and productivity.
