nrf52 best performance

[makouda]

I'm moving from nrf51 to a higher performance uC. I think that there is lot of models of nrf52.

what's the reference of the best nrf52 in term of performance. I want to talk with a set of sensors with 100 Hz each and run a set of complex algorithms.can I with nrf52 use a double SPI or I2C bus??? to perform parallel communications with sensors

It could be a bit hard to take data with freq 100MHz, using uC that is clocked with 60MHz. If you mean 100kHz, I would try with timer/pin triggered SPI DMA transactions to retrieve data, but You should do calculations on your own to check if you will fulfill timing requirements...
