A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

The 90 nm CPUs (9000 and 9100 series) bring dual-core chips and an updated microarchitecture adding multithreading and splitting the L2 cache into a 256 KB data cache and 1 MB instruction cache per core (the pre-9000 series L2 cache being a 256 KB common cache). All Itaniums except some 130 nm models are capable of >2-socket SMP.

It is an updated version with higher speeds, more cache and integrated accelerators. It is manufactured on a 32 nm fabrication process. [19] The first boxes to ship with the POWER7+ processors were IBM Power 770 and 780 servers. The chips have up to 80 MB of L3 cache (10 MB/core), improved clock speeds (up to 4.4 GHz) and 20 LPARs per core. [20]
