Template:mpu Core i5-7287U is a 64-bit dual-core mid-range performance x86 mobile microprocessor introduced by Intel in early 2017. This chip, which is based on the Kaby Lake microarchitecture, is fabricated on Intel's 14nm+ process. The i5-7287U operates at 3.3 GHz with a TDP of 28 W supporting a Turbo Boost frequency of 3.7 GHz. The processor supports up to 32 GiB of dual-channel non-ECC DDR4-2133 memory and incorporates Intel's Iris Plus Graphics 650 IGP operating at 300 MHz with a burst frequency of 1.1 GHz. This specific GPU incorporates an additional 64 MiB of eDRAM L4$.

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.
