Over the years, you might have heard about our commitments–like the 25×20 initiative–to continuously improve the energy efficiency of AMD products. Our most recent endeavor has been the Polaris architecture, which enables us to craft new products that offer up to 2.8X the performance per watt of power versus products gamers might’ve owned just two years ago.1 But performance per watt, or “perf/W” as the slang goes around here, is a metric that’s often difficult to imagine or relate to when scaled out to millions of graphics cards. What does a commitment to performance per watt actually do for our planet? With the assistance of Pure Strategies, we’ve just finished a new study (PDF) to answer that very question.
Looking at the new Radeon™ RX 480 graphics card, we determined that an upgrade cycle favoring this affordable powerhouse could stop as much as 1.9 million metric tons of carbon dioxide (CO2) from entering our atmosphere every year.2 But 4,235,459,252 pounds (1.92 billion kg) of a colorless and odorless greenhouse gas is still pretty difficult to imagine. So, what if we expressed the savings as things we know and can see? Using the methodologies and results described in our paper, we did the math:
- According to American Forests, America’s oldest non-profit environmental conservation group, the average automobile emits about 8,320 pounds of CO2 every year. That means upgrades to the Radeon RX 480 graphics card could offset an entire year of driving from over 500,000 automobiles.
- According to NC State University, the average American tree can offset about 48 pounds of CO2 per year. In other words: many users switching to Radeon RX 480 graphics cards could be equivalent to as many as 88.2 million trees.
- According to the US EPA greenhouse gas calculator, the 2.78 billion kWh annual energy savings determined in our paper could offset an entire year of power consumption from about 290,000 average American homes.2
- Based on electricity costs from the US Energy Information Administration, the same 2.8 billion kWh annual savings from our report represents about $350,000,000 USD in saved energy costs!3
There are so many interesting ways to interpret the data we uncovered in the course of our energy efficiency study. But no matter which way you slice it, AMD’s commitment to energy efficiency with the Polaris architecture can have a real and significant impact on the health of the world we live in.
