A 31.7-fold surge breaks Kume’s Law AMD’s bull-blown six years ago

Remember AMD’s 25×20 goal in 2014? By the end of 2020, APU processors will be 25 times more energy efficient (performance-to-power ratio). The goal, which was once seen as a “bragging” few believed, has now been achieved by AMD. According to AMD officials, the new Renoir APU, ryzen 7 4800H, is 31.7 times more energy efficient than the 2014 baseline, well above the 25-fold target set at the time.

It is understood that the latest Renoir APU brings the 7nm process, Zen 2 CPU architecture, and the upgraded Vega GPU architecture is a historic leap forward in energy efficiency, from 10.88 times from the previous generation to 31.77 times.

AMD says greater energy efficiency offers significant benefits to users, including longer battery life, better performance, lower energy consumption, and less environmental impact.

“We’ve always been concerned about processor energy efficiency, but in 2014 we decided to pay more attention to that capability,” said Mark Papermaster, AMD’s Chief Technology Officer and Executive Vice President. Our team of engineers has worked with collective wisdom to find ways to achieve the goal of increasing energy efficiency by 25 times by 2020. Today we’re well ahead of our original goal of a 31.7-fold increase, giving games and ultra-thin notebooks unmatched performance and graphics features, as well as long battery life. I am proud of our engineers and business team. “

It is well known that the energy efficiency of a processor depends on the amount of energy consumed per unit of total work. To achieve its 25-by-20 goal, AMD achieves energy efficiency gains by focusing on developing highly integrated and effective SoC architectures, enhanced real-time power management features, and silicon-grade energy optimization.

For a designated task, AMD reduced average computing time by 80 percent from 2014 levels, while also reducing energy consumption by 84 percent.

This means that if a company upgrades all 50,000 AMD notebooks in 2014 to the new 2020 model, it will achieve more than five times the computing performance, while the associated notebooks will consume 84% less energy.

When the laptops are used for more than three years, the company will save about 14 billion kilowatt hours of electricity and reduce carbon emissions by 971,000 kilograms, equivalent to the 16,000 trees that have grown over a 10-year life.

It is reported that the performance improvement and energy reduction of the Ryzen 7 4800H processor exceeds the historical efficiency trend predicted by Kumey’s Law (similar to Moore’s Law, which describes the trend of energy efficiency improvement, i.e. the same amount of computation is reduced by half every 18 months).

“Six years ago, AMD challenged itself with a plan to dramatically improve the energy efficiency of mobile processors in real life,” says Dr. Jonathan Koomey, an expert in energy-saving computing. I checked the data and AMD exceeded its 25-by-20 goal in 2014 with improved design, efficient optimization and a high focus on ‘energy efficiency’, up 31.7 times more energy efficiency than its 2014 product. AMD has gone far beyond the energy efficiency boost in Kume’s law. “

Kevin Krewell, chief analyst at TIRIAS Research, said: “AMD has set bold and open engineering targets to increase processor energy efficiency by 25 times, well above historical averages. Its mobile processors also lead the industry as they complete the process. The 25-by-20 goal requires major innovations in architecture, design, and software, rather than relying solely on advances in silicon process technology. Achieving or even exceeding such challenging goals is a testament to the great commitment of the AMD team to its products and putAMD at the fore in the mobile processor space. “

Bob O’Donnell, president of TECHnalysis, said: “Six years ago AMD announced a seemingly random and abstract goal of making its mobile processors 25 times more energy efficient by 2020. And now, when they go beyond the goals they set, it becomes even more significant. Lower energy consumption has never been so important to the planet. The ability of a company to achieve this goal while achieving strong processor performance is a good testament to AMD’s ability to become a market-oriented enterprise focused on engineering. “

The implication behind this is that achieving the 25-by-20 energy efficiency goal not only provides a strong user experience, but also further strengthens AMD’s leadership in sustainability. AMD was the first semiconductor company to have its own climate protection goals, and the 25-by-20 program was certified as the Scientific Carbon Target Initiative, which is considered a powerful measure to help reduce the environmental impact of computing.
