Intel Core i5-4278U is a low-voltage mid-range processor announced in Q3 of 2014. Part of the “Haswell” generation, the CPU operates at a base frequency of 2.6GHz. If a higher frequency is needed, its two cores can overclock, and the frequency goes up to maximum of 3.1GHz.
The chip is equipped with 128KB of first level cache, 512KB of second level cache, and 3MB of third level cache. The Core i5-4278U has been developed using a 22nm process, allowing for the integration of the Intel Iris Graphics 5100 controller. The iGPU operates at a base frequency of 200MHz, while Turbo Boost can increase that to 1100MHz. Power consumption of the whole SoC (System on a Chip) is 28 watts with a maximum operating temperature of 100C.
Intel Core i5-4278U supports TurboBoost, HyperThreading (additional virtual core for every physical one), PCI Express 3.0, up to 16GB of DDR3L-1333/1600/ and LPDDR3-1333/1600 memory. Features like AVX2.0 and the SSE4 instruction set are also supported.
