Wow. I can't believe that sentence made it into an article, let alone one on IEEE Spectrum.
First, normal people don't know how much RAM is in a phone. Second, the numbers are reasonably identical (only differing by 2.4%) so what's the point of specifying it out that way? Why not figure out what an average amount of RAM in a new computer is (4GB?) and say "That's the RAM of about 70k new Desktops".
