While celebrating the first anniversary of its Atom processor family, Intel has announced the launch of two new models: Z550 (2 GHz) and Z515 (1.2 GHz). These 45-nm processors work externally at 533 MHz, have 512 KB L2 cache and are targeted to MIDs (Mobile Internet Devices). The Z515 also features Burst Performance Technology, which enables it to automatically adjust its internal clock depending on computing demand. These new Atom processors will reach the market by the end of this month.
