Template:mpu Core i7-6785R is a 64-bit quad-core x86 high-end performance desktop microprocessor introduced by Intel in early 2016. The i7-6785R, which is based on the Skylake microarchitecture and is fabricated on a 14 nm process, has a base frequency of 3.3 GHz and a turbo boost frequency of up to 3.9 GHz with a TDP of 65 W. This processor incorporates the Iris Pro Graphics 580 integrated graphics operating at 350 MHz with a turbo frequency of 1.15 GHz and incorporating 128 MiB of eDRAM on-package. This model supports 64 GiB of dual-channel DDR4-2133 memory.

Note that while being sold as a desktop part, this chip is still a Skylake H part which uses an FCBGA-1440 package which is soldered on the motherboard and cannot be replaced or upgraded like the rest of the mainstream desktop Skylake modes which use FCLGA-1151.

Cache

Main article: Skylake § Cache

[Edit/Modify Cache Info]

hierarchy icon.svg
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.
