    It depends entirely on your design. When you compile something in Quartus it will give you the maximum frequency a given compiled design can run at. Adding pipeline stages to an existing design can help increase its maximum frequency, at the cost of a higher latency. Speed is highly correlated to clock frequency, but it also depends on what you call speed. Optimising the design can be more important for speed than the actual clock frequency.

    I am using 50MHZ frequency and while transmiiting the data it takes so much of delay at the receiver end I apologise for the silly questions as i am new to the fpga design

    What kind of data, what kind of interface? What delay do you get and what would you like to have instead?
