I don't know, but I can tell you that single core C programm can calc up to 170 000 SHA1 per second
why are you interested in this?
You can find some benchmarks here:

The MIPS value can be calculate with the clock rate (MHz) and the cycles per instruction (CPI). According to the information in the following site:https://software.intel.com/en-us/node/545142, the MCU subsystem is based on the i486 architecture and it runs at 100MHz when it's fully active.
According to the article "The i486 CPU: Executing Instructions in One Clock Cycle", the CPI of the i486 is 1 (one cycle per instruction). This means that the MIPS value would be 100MIPS, but let me double check this to be sure.
