L2 cache

L2 cache

(Level 2 cache) A memory bank built into the CPU chip, packaged within the same module or built on the motherboard. The L2 cache feeds the L1 cache, which feeds the processor. L2 memory is slower than L1 memory. See cache.


L2 Cache Locations
Modern CPU chips have a built-in L2 cache; however, L2 caches have resided outside the CPU on earlier computers.

In the private cache organization, most of the L1 cache misses can be handled by the L2 cache, so the number of remote on-chip L2 cache accesses is reduced and it is not necessary to cross the interconnection network, which reduces the miss latency.

The improvement in computing power from 56 400 MHz R12000 chips to 156 500 MHz R14000 processors with 8MB L2 cache and 1:1 processor-to-cache ratio has allowed us and the research community that we serve to tackle some very big data problems in new ways," said Dardy.
The chip costs (in 1,000 unit quantities) $931 for the 500MHz version with 512 KB L2 cache; $1,980 for the 500MHz with 1MB L2 cache and $3,692 for the 500MHz with 2MB L2 cache.
A unique L2 private memory mode allows system designers the choice of operating the processor's L2 cache as either a fast backside cache or as high-speed system memory, ideal for storing interrupt service routines or critical data structures.
That gives the K6-III a total of 320KB of combined L1 and L2 cache, more than any other x86 CPU, and up to 1,344Kb in total.
