    just a thought,

    A CPU has its clock limited because of the propagation delay which will no let it function after a certain frequency.

    Most register's and sequential logic is based on JK flip flops, which are built on propagation delay.

    Does this limit the theoretical maximum speed of processors designed using flip flops?

    how would one go about storing data (building a flipflop) if we were able to implement a circuit made up of gates with no propagation delay?

    obviously studying this at the moment, 1st yr Elec Eng. I just thought about this today and would like to know more on the topic.

    I question your statement -
    I believe it would be more accurate to say that, because sequential logic is made with real-world components, propagation delays are unavoidable. Even voltage effects can only propagate at light speed.

    Your ideal logic, made from properly doped unobtanium, can obviously clock at any frequency whatever.

    Assuming there is no heat dissipated in the unobtanium circuit ofcourse.
