I don't see a reason the Mac Pro has to have a more powerful CPU than the Mac Studio. For example the Macbook Pro and Macbook Air also share the same CPU at certain levels. The difference could be in expandability (PCIe slots) and RAM if they are able to either move the RAM off-die or have a NUMA architecture. Interesting to speculate though. So far they also haven't launched a multi-socket product, maybe that's what the Mac Pro could launch with.
