How big is the L1 cache?
L1 is usually part of the CPU chip itself and is both the smallest and the fastest to access. Its size is often restricted to between 8 KB and 64 KB.
What is the minimum size of L1 cache memory?
L1 cache is generally built into the processor chip and is the smallest in size, ranging from 8KB to 64KB. However, it’s also the fastest type of memory for the CPU to read. Multi-core CPUs will generally have a separate L1 cache for each core. L2 and L3 caches are larger than L1, but take longer to access.

L1 hit-rate is still very important, so L1 caches are not as small / simple / fast as they could be, because that would reduce hit rates. Achieving the same overall performance would thus require higher levels of cache to be faster.
What is Cacheline size?
