AMD recently announced that their 3rd Gen AMD Ryzen Processor with Radeon Vega Graphics exceeds their 25×20 goal as an energy efficient mobile processor. They also target to improve the energy efficiency further by 25 times by the end of 2020. Their all new AMD Ryzen 7 4800H mobile processor shows positive outcome by 31.7 times from 2014, thus boosts the processor performance while retaining its energy efficiency at the same time. In general, the greater the energy efficiency, the better battery life achievable in real-time, with boosts in performance and reducing environmental impact from electronic computing.
“We have always focused on energy efficiency in our processors, but in 2014, we decided to put even greater emphasis on this capability. 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 longer battery life. I could not be prouder of our engineering and business team” – Mark Papermaster, Chief Technology Officer and Executive Vice President, Technology and Engineering at AMD.
In general, energy efficiency for processors were determined by the total amount of work performed per unit of energy consumed. In order to achieve the goal, AMD focused on improvements on developing a highly integrated and efficient system-on-chip (SoC) architecture, improved, real-time power management features, and silicon-level power optimizations. In addition, AMD reduced the average compute time for a given task by 80% from 2014 to 2020, while achieving an 84% reduction in terms of energy usage. Such move leads to 50,000 AMD-based laptop from 2014 models to 2020 models would achieve five times more computing performance and reduce the associated laptop energy consumption by 84%, which over a three-year service life amounts to save approximately 1.4 million kilowatt hours of electricity and 971,000 kg of carbon emissions, equal to 16,000 trees grown for 10 years. AMD strives to achieve its 25×20 energy efficiency goal by retaining best user experience and solidifies AMD’s leadership in sustainability. Recalling the semiconductor chronology backwards, AMD was the first company to have its climate protection goals, this includes 25×20, which further approved as a “science-based target” by the Science Based Target initiative.
Summary of AMD’s 25×20 Goal Achievements:
- Leadership CPU and GPU architectures tightly integrated into a common SoC, including multiple generations of the award-winning “Zen” architecture
- Innovation in real-time power management
- Continued evolution of the AMD Infinity Fabric™ architecture
- Silicon-level power optimizations
- Rapid adoption of cutting-edge process technology
From industry perspective, the performance improvements and reduced power consumptions of the Ryzen 7 4800H processor outpaced the historical efficiency improvement trend as predicted by Koomey’s Law by two times from 2014 to 2020.
“Six years ago, AMD challenged itself to dramatically improve the real-world energy efficiency of its mobile processors. I have reviewed the date and can report that, AMD exceeded the 25×20 goal it set in 2014 through an improved design, superior optimization and a laser-like focus on energy efficiency. With a chip 31.7 times more energy efficiency than its predecessor, AMD has far outpaced in real-world efficiency gains that would be expected from a traditional Moore’s Law pace as embodied in Koomey’s Law.” – Dr. Jonathan Koomey, an Industry expert on energy efficient computing.
“AMD undertook an audacious and public engineering goal to improve its processor efficiency by 25 times, vastly outpacing historical averages, and in doing so, achieved an industry-leading position in mobile processors. The 25×20 goal required major changes to architecture, design and software, and did not rely solely on silicon process technology advancements. Achieving and surpassing this challenging goal is a testament to the hard work of the AMD team put into its products and its catapulted AMD further to a leadership position in mobile processors.” – Kevin Krewell, principal analyst at TIRIAS Research.
Quoting from Bob O’Donell sentence, “AMD’s goal of improving the power efficiency of its laptop processors 25 times by this year may have seemed like a bit of an abstract, arbitrary target when they first announced it, six years ago. But as they surpass that impressive goal, it becoming significantly more meaningful. Lower energy consumption has never been more important for the planet and the company’s ability to meet its target while also achieving strong processor performance is a great reflection of what a market-leading, engineering-focused company they’ve become.”
