What's interesting is that way back in 2013, when analysts noticed that Apple had packed ~1B transistors into an area of 102mm^2 on 28nm (at the time, Intel had released 22nm Haswell with 0.96B transistors in an area of ~130mm^2), BK had the following to say:
He basically said, "we're denser, trust us" but Intel never actually disclosed a transistor count. Seems a little strange, wouldn't they want to show off how much denser their tech is with actual numbers?
Technically if you look at say SRAM cell sizes (both optimized for density), Intel 22nm was ahead of TSMC/Samsung 28nm, but maybe the advantage when translated into real product (which contained more than SRAMs) wasn't as large.
It would be nice if Intel were to publish more details on its SoC products.
