AMD announces that the Ryzen 7 4800H destroys its 25x20 power-efficiency goal

In 2014, AMD set forth an aim to improve the power efficiency of its processors by 25 in 6 years. Now, in 2020, the company asserts that it has not only met that goal but exceeded it. This has been done in the form of the Ryzen 7 4800H APU.

"25x20" is the name of an initiative by AMD to refine the power efficiency of its processors by 25 times within 6 years. That was back in 2014; however, perhaps not even that past version of the company may have foreseen its prowess in meeting that goal.

Today, (June 25, 2020) AMD has announced that one example of the resulting APUs, the Ryzen 7 4800H, has a power-efficiency rating that is not merely 25 times, but is in fact 31.7 times, that of a corresponding 2014 chipset.

Its maker has attributed this achievement to factors such as the work put into developing its class-leading Zen 2 architecture; the step up to a 7-nanometer (nm) manufacturing process in fabricating the same; and general improvements in real-time power management at AMD.

Therefore, it may seem enhanced power efficiency is a mere side-effect of this evolution in technology. However, this property may also result in advantages such as improved performance, longer battery life and, of course, reduced energy bills while using a PC.

To this end, AMD estimates that switching 50,000 of laptops with its silicon from 2014 for the same number of 2020 machines would save approximately 1.4 million kilowatt-hours (kWh) of electricity, as well as 971,000 kilograms' (kg) worth of carbon emissions.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
