It's not ONLY about the specs of a device, that makes it perform well. Software has a huge factor. Just look how iOS handles graphics better than any other mobile operating system out right now. Yet the devices that iOS run on have bare minimum amounts of ram and slower clock speed than the competitors.
that would be high market share leading to developers to actually optimize code, instead of writing sloppy code and hoping the horsepower of the device hides the shoddy code.
for years the 7mhz Amiga outperformed 200mhz Pentium PCs, mostly because of incredibly optimised code.
