The CDC 6600 used a simplified central processor (CP) that was designed to run mathematical and logic operations as rapidly as possible, which demanded it be built as small as possible to reduce the length of wiring and the associated signalling delays. This led to the machine's (typically) cross-shaped main chassis with the circuit boards for the CPU arranged close to the center, and resulted in a much smaller CPU. Combined with the faster switching speeds of the silicon transistors, the new CPU ran at 10 MHz (100 ns cycle), about ten times faster than other machines on the market. In addition to the clock being faster, the simple processor executed instructions in fewer clock cycles; for instance, the CPU could complete a multiplication in ten cycles.
