Between our smartphones, tablets, and ereaders, many of us carry one or more mobile device around without realizing just how powerful it is.
Sure we may joke about how a graphing calculator has more processing power than the entire world had in 1950, but it turns out that the quip is even more true than I had realized.
The following infographic breaks down how the devices we have today compare with supercomputers of the past.
For example, the iPad 2 would be one of the 5 most powerful computers in the world if it fell through a wormhole to 1994. (Of course, that would only be true if measured in terms of sheer numbers, not actual computing ability, which raises a whole different issue of general-purpose vs restricted computing.) And that tablet isn’t even all that impressive by the standards of 2015; there are plenty of $100 tablets that are more powerful.
