Is the Prime the fastest calculator ever made?

Numworks CPU is a newer generation, but the generation gain is far from compensing for the clock speed difference. The latest 12C does also have a cortex M4 and the speed gain was around 1.3 times compared with the ARM7 based one.

Also, the cortex FPU only supported 32 bits floats. Which is very limited for doing calculator math.

Some interesting info on 32 bit floats here:

The link to the benchmark for Cortex is broken but can be reached via Wayback:

Although the Cortex achieves a very large speed increase for 32bit floats versus doubles, it seems the processor used in the Prime might achieve a factor of 2 increase if there was a mode to use this for math. Agreed its limited precision but might be useful under some circumstances.
