From their website:
The 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. (for more information look int type page).
CPU Clock at 84Mhz.
96 KBytes of SRAM.
512 KBytes of Flash memory for code.
a DMA controller, that can relieve the CPU from doing memory intensive tasks.
Took all of 15 seconds Jane.... You really should have included this.
