Intel Core i5-4288U is a low-voltage, integrated (soldered onto the motherboard) processor, announced in Q3 of 2014. It is part of the “Haswell” generation and operates at a base frequency of 2.6GHz. If a higher frequency is needed, its two cores can overclock, and if they both operate in tandem, they go to 3.1GHz. The frequency does not change if only one core works.
The chip is equipped with 128KB of first level cache, 512KB of second level cache, and 3MB of third level cache. The Core i5-4288U has been developed using a 22nm process, allowing for the integration of the Intel HD Graphics 5100 controller. It operates at a base frequency of 200MHz, while Turbo Boost can increase that to 1200MHz. Power consumption of the whole SoC (System on a Chip) is 28 watts with a maximum operating temperature of 100C.
Intel Core i5-4288U supports TurboBoost (increasing the clock frequency when necessary), HyperThreading (additional virtual core for every physical one), PCI Express 2.0, up to 16GB of DDR3L 1333/1600, AVX2.0 and the SSE4 instruction set.
