To me it looks like the frequency of the control loop, not the cpu core frequency was meant? 1kHz is typical for i.e. steering or abs control loops.

The bottleneck is not the CPU, nor the model running in the loop, but the IO devices and driver's costing latency. In real-time latency kills you. Which turns out to be bended cables, missing resistors, broken filters, or such. A simple cycle-miss in real-time means reboot or worse.
