It depends on the implementation. Ion traps are slower than superconducting qubits, for example, although they are speeding up. This paper, from 2014, gives some parameters: "Logic gates at the surface code threshold: Superconducting qubits poised for fault-tolerant quantum computing" Campbell et al.
