The 604 core was a deadend at Moto/Freescale/name_of_the_week, all newer CPUs/SOCs can be traced back to the 603.

603/604 are also called G(eneration)2.

The CPUs on Phase5 PPC cards are crippled by a slow RAM interface, a "pure" 604 (say an old Mac or clone) should be able to beat the EFIKA clock for clock.
