The Arduino Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are:
A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock.
CPU clock at 84Mhz
96KBytes of SRAM
512K Bytes of flash memory for code
A DMA controller, that can relieve the CPU from doing memory intensive tasks
