From Wikipedia:

The PowerPC 604ev, 604r or "Mach 5" was introduced in August 1997 and was essentially a 604e fabricated by IBM and Motorola with a newer process, reaching higher speeds with a lower energy consumption. The die was 47 mm2 small manufactured on a 0.25 µm CMOS process with five levels of interconnect, and drew 6W at 250 MHz. It operated at speeds between 250 and 400 MHz and supported a memory bus up to 100 MHz.
