Is the Prime the fastest calculator ever made?

Claudio, you mentioned twice that the Numworks calculator has a Cortex M4 processor in it. When I look at the Numworks site, their specs say it has an 100 MHz ARM v7 processor.

Is ARM v7 the same as Cortex M4, or am I confused?

If the Numworks is faster, I am looking for the fastest handheld platform for my 8080 simulator.

Thanks,
