Just a little more than four years ago, we announced a six-year goal to dramatically improve the energy efficiency of our mobile processors. AMD’s 25x20 initiative is our vision to strengthen the energy efficiency of our accelerated processors (APUs) for mobile devices by 25x by year 2020.

 

When we undertook the challenge, we set a clear vision and goal, had a number of very promising approaches, yet the specific path to 25x was not complete. We had a strong roadmap that stretched over several years, and the team made several educated assumptions based on our insights. Those included, for instance, the pace of process node advancement from our fab partners and improvements we could foresee in microarchitecture and efficiency algorithms. Four years in and I am happy to report that our assumptions were sound, and we remain on track to achieve this goal.

As you can see from the graphic above, the path to 25x is steep. In the semiconductor industry vernacular, this is a “heavy lift.”

 

To achieve this, we are continually refining the design of our processors to make them ever more efficient. This requires increasing performance to meet the demands of new generations of more capable software while maintaining or reducing power consumption. According to Dr. Jonathan Koomey, one of the world’s experts on computing efficiency, “What AMD is doing is no small thing, as the 25x goal over a six-year period outpaces the historical gains predicted by Moore’s Law by 70 percent. It’s efforts such as 25x20 that will enable exciting new technologies ranging from the Internet of Things and big data analytics to virtual reality and deep learning.”

 

At the 2014 initiative launch, we said that innovating for energy efficiency and developing low-power products had always been a design goal at AMD. This commitment remains as strong today as it was then. This pursuit is more important than ever, during a time when the number of computing devices continues to expand in our energy constrained world. Yet, the potential for technology to help solve some of the world’s greatest challenges grows every day.

 

I am incredibly proud of the contributions AMD employees have made to date to help enable the researchers, innovators and creators in our world to make positive impact using more energy efficient devices. Recently, AMD was honored to receive the California Governor’s 2017 Environmental & Economic Leadership Award, California's highest environmental honor.

We continue to innovate and advance towards our goal. An upcoming AMD Ryzen™ processor with AMD Radeon™ Vega Graphics is expected to make additional strides. This includes improvements in every key metric in our 25x20 initiative: more compute performance, more graphics performance, lower power during heavy usage, and significantly lower power during light usage. These advancements mean the Ryzen™ processor with Radeon™ Graphics is expected to be both the eco-friendliest and the fastest APU we’ve ever built. Upon introduction of our latest processor, we expect to be 25 percent closer1 in our quest to 25x20 in a single processor generation.

 

While we’ve still more to accomplish before we achieve our 25x20 goal, we look forward to further architectural innovation and power management techniques. I’m very excited about what’s still to come. We will continue to report on our progress toward achieving the 25x20 energy efficiency goal, as we strive to help consumers make positive differences through energy efficient innovation.
