AMD A8-4555M is a low-voltage, integrated, low-end processor announced in Q3 of 2012. It is part of AMD’s
“Trinity” architecture family and operates at a base frequency of 1.6GHz. If a higher frequency is needed, its cores can overclock to 2.4 GHz.
The chip is equipped with 128KB of first level cache and 4MB of second level cache. A8-4555M has been developed using a 32nm process, allowing for the integration of the AMD Radeon HD 7600G graphics controller, with a base frequency of 320MHz (or 685MHz dynamic maximum). It supports DirectX 11 applications. Power consumption of the whole system on a chip is 19 watts, with a maximum operating temperature of 100C. AMD A8-4555M supports TurboCore (increasing clock frequency when necessary), PCI Express 2.0, DDR3L/U 1333/1066 memory, the SSE4a and FMA4 instruction sets.
