Inside Intel’s Haswell CPU: Better performance, all-day battery
By Loyd Case, PCWorld Sep 13, 2012 6:00 AM print PC users on the go require long battery life, but don’t want to sacrifice performance. Balancing these contradictory requirements are at the heart of Intel's new CPU architecture, code-named Haswell, which is expected to appear in shipping tablets, ultrabooks and other computers in 2013. At the 2012 Intel Developer Forum earlier this week, Intel dove deeper into what makes Haswell tick. Or maybe "tock" would be a better word, as Haswell represents the "tock" in Intel's CPU development program. Intel uses “tick-tock” to denote its CPU development strategy. A “tick” is represented by an existing CPU design that's tweaked only a bit, but enjoys all the efficiencies of a new manufacturing process. Ivy Bridge represents a tick, incrementally improving on Sandy Bridge, but moving to 22nm. New architectures like Haswell, meanwhile, are always built...
