Core i7-8709G is a 64-bit quad-core high-end performance x86 mobile microprocessor introduced by Intel in early 2018. This processor, which is based on the Kaby Lake microarchitecture, is manufactured on Intel's improved 14nm+ process. The i7-8709G operates at 3.1 GHz and a Turbo Boost frequency of up to 4.1 GHz. This MPU supports up to 64 GiB of dual-channel DDR4-2400 memory and incorporates Intel's HD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.1 GHz. Additionally, this processor also incorporates a discrete Radeon RX Vega M GH GPU with its own 4 GiB of high-bandwidth memory.

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.
