Core i7-7820X is a 64-bit octa-core high-performance x86 desktop microprocessor introduced by Intel in mid-2017. This chip, which is based on the Skylake microarchitecture, is fabricated on Intel's enhanced 14nm+ process. The i7-7820X operates at 3.6 GHz with a TDP of 140 W and a Turbo Boost frequency of 4.3 GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory.

In addition to its Turbo Boost frequency, the i7-7820X has a Turbo Max frequency of 4.5 GHz.

Cache[edit]

[Edit/Modify Cache Info]

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.
