Core i7-8705G 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 i7-8705G operates at 3.1 GHz with a TDP of 65 W 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 GL GPU operating at up to 1.011 GHz with its own 4 GiB of high-bandwidth memory operating at 700 MHz.

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.

Cache[edit]

Main article: Kaby Lake § Cache

[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.

Graphics[edit]

This processor has two graphics processors:

• HD Graphics 630 GPU, same die
• Custom Radeon RX Vega M Graphics GPU, same package

Note that both GPUs are enabled and both can be operated independently.
