According to the benchmark scores, in terms of single-core scores, the new base Mac Pro model scores considerably lower than the iMac Pro, which at the moment currently sits at the top of Geekbench’s charts amongst Apple’s computers. On the multi-core front, it’s not that much different as the iMac Pro once again trumps the Mac Pro’s base model.
Given that the iMac Pro was not updated since back in 2017, it is rather disappointing that a computer released two years later can’t seem to catch up, and for the price you’re paying, it doesn’t seem worth it. However, we should note that the higher-end configurations of the Mac Pro pretty much wipe the floor with the iMac Pro, but that’s only if you’re willing to spend that kind of money upgrading it (a fully-specced out Mac Pro would cost over $50,000).
That being said, the upside to the Mac Pro is that it is fully modular which makes it incredibly easy to swap parts in and out. If you plan on keeping the computer around for a long time, then this could potentially save you money in the long run.
