That doesn't sound right: 22 nm * 316 = 69 microns, giving 69^2 == ~4800 square microns; a transistor is larger than the feature size, and don't wires take the majority of the area? (Still, that's well under a square millimeter.)
So we haven't quite reached the day Eric Drexler hinted at with "so-called microcomputers still visible to the naked eye".
Nice catch, in my haste I was dividing and should have been multiplying. Typical transistor size is 4x feature size. So 316 * 2 * .022 ~ 14 microns and squared its ~ 200 square microns.
That said, we are still talking about an incrementally small addition to a chip.
