4th Generation ® ™ Intel Core Processor Architecture BY RYAN SHROUT W hile the 2nd and 3rd generation Intel® Core™ processors were derivatives of prior designs and thought processes, the 4th generation Intel® Core™ processor (codenamed Haswell) is something completely different. The microarchitecture of this processor is similar to that of the 2nd gen Intel Core processor, but with differences that are more philosophical than technological. Intel's target was a converged core: a single design that is flexible enough to be utilized in mobile devices while also scaling to the performance levels required for workstations and servers. The 4th generation Intel Core processor retains a majority of the architecture design from the 2nd and 3rd gen Intel Core processor architectures, including the core design as well as the key features that make Intel's processors unique: Intel® Hyper-Threading Technology, Intel® Turbo Boost Technology, and the ring interconnect. 1 I nte l ® Sof t w are Adren al ine
