Intel Core (TM) and 5th generation of Core (TM) 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 (TM) 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 mV. 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. |
