Intel Core i7-4558U

Intel Core i7-4558U is an integrated (soldered onto the motherboard), low-voltage processor, announced in the third quarter of 2013. It is part of the “Haswell” generation and operates at a base frequency of 2.80GHz. If a higher frequency is needed, its two cores can overclock, and if they both operate in tandem, they go to 3.2GHz. The frequency goes up to 3.3GHz for only one core.

The chip is equipped with 128KB of first level cache, 512KB of second level cache, and 4MB of third level cache. The Core i7-4558U has been developed using a 22nm process, allowing for the integration of the Intel Iris 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 i7-4558U supports TurboBoost (increasing the clock frequency when necessary), HyperThreading (additional virtual core for every physical one), PCI Express 2.0, up to 16GB of DDR3/L 1333/1600 memory, AVX2.0 and the SSE4 instruction set.
