AMD Claims It’s Gaming Chips will be 25 Times More Energy Efficient by 2020
A new energy efficiency study from AMD reveals that its latest high performance gaming chips are about 3x more energy efficient per watt compared to previous generation products. The study follows the last month’s report by the Natural Resources Defense Council (NRDC) which shows that hardware makers can tweak a thing or two that could make computers way more efficient.
We know that high-end PCs use very demanding chips that would continue drawing power needed for the high performance graphics even when you’re simply surfing the web. According to the report issued by NDRC, most computers “spend 50 to 77 percent of their time in idle or low intensity activities,” yet they draw the same processing power as those in use.
Pierre Delforge, Director High Tech Sector Energy Efficiency at NRDC, notes in a blog post that power saving opportunities are already there, such as “fully utilizing the CPU’s capability to lower its power when not doing any work,” or configuring motherboards to power off ports and fans.
AMD is also working in this regards and striving to make its gaming chips as energy competitive as possible. The company claims that its latest Polaris based GPUs deliver 2.8 times the Perf/Watt over previous chips thanks to the latest 14nm FinFET and GCN 4.0 architecture.
Robert Hallock, head of global technical marketing at Radeon Technologies Group division of AMD told GreenBiz in an interview that they are aiming to make their chips up to 25 times more energy efficient over the next four years.
The energy efficiency of our products is a big focus for us. PCs are at an interesting point where you can reduce power consumption for the same performance. We have a couple of corporate imperatives to do that. One is “25-by-20” which is to increase the energy efficiency of our CPUs or processors 25 times by 2020. Now it’s trickling down to graphics.
When you make a CPU or graphics chip, they are so small that individual electrons can escape. When that happens, that’s wasted energy and it adds heat. A new manufacturing technology allows us to clamp down on that.
AMD’s white paper mentions that if, hypothetically, all the 15.8 million performance-grade graphic processing chips sold in 2015 were based on the new manufacturing technology, the electricity savings could reach 2.8 billion kilowatt hours.
