Probably about the same, actually. In my experience, there's often very little speed difference between a straight 'dd' from one partition to another (say, making a disk image prior to data recovery) and doing more complicated work (say, archiving and compressing). Until you actually manage to saturate your CPU with the workload (video editing or something), the time is most likely to be dominated by the disk platters.
