Template:mpu Core i9-7980XE is a 64-bit octadeca-core top-of-the-line x86 desktop microprocessor introduced by Intel in mid-2017. This chip, which is based on the Skylake microarchitecture, is fabricated on Intel's 14 nm process. The i9-7980XE operates at ? GHz with a TDP of 160 W and a Turbo Boost frequency of ? GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory.

The Core i9-7980XE succeeds the Core i7-6950X as Intel's flagship microprocessor based on Skylake microarchitecture - also becoming the first consumer-class octadeca-core microprocessor.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
