No. "bandwidth <value>" is used to convey the speed of the interface to higher level protocol.For example: IGPs uses bandwidth statement to correctly calculate the metric.TCP also adjust the re-transmission mechanism.
Refer to command reference on this link:http://www.cisco.com/en/US/docs/ios/interface/command/reference/ir_a1.html#wp1013415
