AMD Exceeds Goal to Deliver Improvement in Mobile Processor Efficiency
AMD announced it has exceeded its 25x20 goal set in 2014 to improve the energy efficiency of its mobile processors 25 times by 2020. The new Ryzen 7 4800H mobile processor improves on the energy efficiency of the 2014 baseline measurement by 31.7 times, and offers leadership performance and extraordinary efficiency for laptop PCs. Greater energy efficiency leads to significant user benefits including improved battery life, better performance, lower energy costs and reduced environmental impact from computing.
“We have always focused on energy efficiency in our processors, but in 2014 we decided to put even greater emphasis on this capability,” said Mark Papermaster, chief technology officer and executive vice president, Technology and Engineering at AMD. “Our engineering team rallied around the challenge and charted a path to reach our stretch goal of 25 times greater energy efficiency by 2020. We were able to far surpass our objective, achieving 31.7 times improvement leading to gaming and ultrathin laptops with unmatched performance, graphics and long battery life. I could not be prouder of our engineering and business teams.”
Energy efficiency for processors is determined by the amount of work performed per unit of energy consumed. To achieve the 25x20 goal, AMD focused improvements on developing a highly integrated and efficient system-on-chip (SoC) architecture; improved, real-time power management features; and silicon-level power optimizations. AMD reduced average compute time for a given task by 80% from 2014 to 2020, while also achieving an 84% reduction in energy use. Achieving its 25x20 energy efficiency goal not only delivers a stronger user experience but also further solidifies AMD’s leadership in sustainability.
“Stewardship of our planet can go hand-in-hand with developing powerful technology and helping our customers achieve their aims,” said Susan Moore, corporate vice president for corporate responsibility and international government affairs at AMD. “The power efficiency improvements we have made within our laptop processors make a difference in the world around us. Reporting publicly each year on progress and ultimately achieving, and surpassing, the 25x20 energy efficiency goal reflects AMD’s commitment to sustainable technology.”
The performance improvements and reduced power consumption of the Ryzen 7 4800H processor outpaced the historical efficiency trend predicted by Koomey's Law, a Moore's Law analog describing energy efficiency improvement trends, by 2x from 2014 and 2020.
