Intel Core i5-2557M is a low-voltage, mid-range processor announced on June 19, 2011. It is part of the “Sandy Bridge” generation and operates at a base frequency of 1.7GHz. If a higher frequency is needed, its two cores can overclock, and if they both operate in tandem, they go to 2.4GHz. The frequency goes up to 2.7GHz for only one core.
The chip is equipped with 128KB of first level cache, 512KB of second level cache, and 3MB of third level cache. The Core i5-2557M has been developed using a 32nm process, allowing for the integration of the Intel HD Graphics 3000 controller. It operates at a base frequency of 350MHz, while Turbo Boost can increase that to 1200MHz. TDP consumption of the whole SoC (System on a Chip) is 17 watts, with a maximum operating temperature of 100C.
Intel Core i5-2557M supports TurboBoost (increasing the clock frequency when necessary), HyperThreading (additional virtual core for every physical one), Trusted Execution, AES, Intel 64, Anti-Theft and My WiFi.
