Well, increased computing performance is always welcome - but as I've said before, in most cases I don't think CPU performance is the limiting factor for CAKE.

When the CPU load goes up as networking throughput reaches the physical limit of the interface (or the I/O subsystem), what you're seeing is the CPU just spinning its wheels while waiting for a mutex to unblock.  Spinning faster doesn't make the mutex unblock sooner!
