News of the delay stems from a document acquired by X-bit Labs. According to the paper, the processors will use the LGA2011 socket and offer "extra large cache" to maximize the overall speed of single-threaded and dual-threaded applications, the quad-channel memory controller, and "a number of other enhancements."
The documents also reveals that E-Series processors bearing four or six cores will be paired with the Intel X68 "Patsburg" core-logic set. However platforms based on the 6-core processors will offer external base frequency generators but will keep the clock-speeds of USB, SATA and other buses locked. This will allow users to boost the clock speed of the CPU by increasing the Direct Media Interface (DMI) frequencies.
