The L in L1, L2, and L3 stands for "Level", hinting at their hierarchical structure. The L1 cache is the fastest of the lot, with bandwidth close to 1TB/second and just 1 nanosecond of latency.

Almost all modern CPUs feature enough L1, L2, and L3 cache for every day-to-day operation. Besides, CPU cache memory isn't the only thing determining CPU performance.

Nvidia's latest GPUs, the RTX 5090 and RTX 5080, have been closely examined for their L1 and L2 cache configurations, as well as memory enhancements. According to recent reports by Tom's Hardware ...
