 On AVR platforms, the highest achievable step rate is with just one
 stepper stepping. On the SAMD21 and STM32F103 the highest step rate is
 with two simultaneous steppers stepping. On the SAM3X8E, SAM4S8C,
 SAM4E8E, LPC176x, and PRU the highest step rate is with three
-simultaneous steppers. On the SAMD51, the highest step rate is with
-four simultaneous steppers. (Further details on the benchmarks are
-available in the [Benchmarks document](Benchmarks.md).)
