The most recently sold micro-processors used in a mass market product that come to mind are the CPUs of the Wii/PS3/Xbox 360 era consoles (in particular the PPC750CL in the Wii is a pure CPU). The Wii U then glued three of those together into a three-core die, so if you're willing to consider just the CPU die and not the entire MCM, that one was also a pure CPU.

Digi-Key still shows the 750CL in stock, but it's obviously an obsolete product at this point.
