Broadwell: A family of IA 14nm processors

Intel Core™ M and 5 th generation of Core™ processors (code named Broadwell) are fabricated on an optimized 14 nm process technology node resulting in a 49% reduction in feature-neutral die area. 14nm created a new optimized process flavor for Core™ M to improve energy efficiency for mobile devices. Techniques and optimizations were implemented to deliver 2.5x TDP reduction coupled with up-to 60% higher graphics performance. New process technology combined with various design techniques reduced the minimum voltage of operation by 50 m V. Broadwell introduces the second generation of Fully Integrated Voltage Regulator with better droop control and parallel boot LVR along with other power-reduction features resulting in 35% reduction in active and standby power over first generation. 3DL inductor technology introduced for the first time in Broadwell, enables 30 % reduction in package thickness and improved low-load efficiency. IO re-partitioning of the SOC and a major re-design of DDR system resulted in 30% reduction in I/O power. Shutting down various parts of the SOC die in various idle states (C∗ states) resulted in 60% reduction in the idle power. New software controlled co-optimization methods were implemented such as duty-cycle control and dynamic display support to improve the energy efficiency of the graphics and the display subsystem.
