For Apple to produce a Mac Pro with the same performance as an Intel it will have to have a substantial amount more cores than the Intel counterpart.

Apple's current A13 big core is lot more powerful than Neoverse N1 Arm core (which is found on most recent ARM server chips) which is Cortex A76 based.
The A13 has decent single threaded performance, but poor multithreaded performance. Apple used the A12z in newer iPads and the devkit, which has worse single core performance, but better multi-core performance. An A13 has a 7w TDP. Getting AMD renoir level of performance from the A13 would require a 20-25w TDP, higher than Renoir. The A13 runs HOT. Note that Renoir would have slightly slower single core performance. This is last-gen Apple vs AMD. Apple is moving to 5nm while AMD is staying on 7nm for another year. We will see what things look like EOY.

A13 is 2+4 while A12z is 4+4.
