What processors does it use, the 80486? It says fourth generation processors (8086, 80186/80286, 80386, 80486), so I guess that's it. The 486 is a fine processor, no doubt, but I hope they seriously bumped the clock speed past 133 MHz.
I think ARM is better suited for this kind of task, especially in the power consumption area, because even with the ULP version, Haswell is a bit overkill
