why use the same 32Mhz external crystal, NRF52840 run quicker double than NRF52811

Hi nordic support Team.

I try to build blinking led example: nRF5_SDK_17.0.2_d674dde\examples\peripheral\blinky\pca10056e
Load firmware for NRF52811 and NRF52840, i see that speed of NRF52840 faster double than NRF52811.
Can i know the reason?
same example, same 32Mhz external crystal.

Both nRF52840 and nRF52811 have same M4 MCU running on same clock speeds. I am not sure what you mean double the speed? Which speed are you measuring? Please give numbers you are seeing and how you measured them.
