Template:mpu Core i7-7740K is a 64-bit quad-core high-end performance x86 desktop microprocessor set to be introduced by Intel in 2017. This processor, which is based on the Kaby Lake microarchitecture, is manufactured on Intel's improved 14nm+ process. The i7-7740K operates at 4.3 GHz with a TDP of 112 W and with a Turbo Boost frequency of 4.5 GHz for a single active core. This MPU supports up to 128 GiB of dual-channel non-ECC DDR4-2666 memory.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

[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.
