Wilson, Matthew Merten, Srinivas Chennupaty, Wilfred Gomes, Rajesh Kumar Intel, Hillsboro, OR The 4th Generation Intel® Core™ processor, codenamed Haswell, is a family of products implemented on Intel 22nm Tri-gate process technology [1]. The primary goals for the Haswell program are platform integration and low power to enable smaller form factors. Haswell incorporates several building blocks, including: platform controller hubs (PCHs), memory, CPU, graphics and media processing engines, thus creating a portfolio of product segments from fan-less Ultrabooks™ to high-performance desktop, as shown in Fig. 5.9.1. It also integrates a number of new technologies: a fully integrated voltage regulator (VR) consolidating 5 platform VRs down to 1, on-die eDRAM cache for improved
