Intel has incorporated a number of architectural enhancements into Penryn that are designed to deliver clock-for-clock performance enhancements over today’s Core 2 CPUs at a given clock speed. One key new technology Intel has incorporated into Penryn is their Fast Radix-16 divider. Intel’s Radix-16 divider is a new divider technique providing double the divider speed over previous processors when handling math computations (both floating-point and integer operations): 4-bits processed per cycle in Penryn versus 2-bits per cycle in today’s processors.
