Iām not certain thatās a forgone conclusion. The March iPad Pro has lower clock speeds than the iPhone 11 I believe. More cores equals more heat than canāt be dissipated?
Nothing is a forgone conclusion, correct.
However, a few things of note;
1. iPad Pro is using two year old CPU design, A12. A12Z is just enabling an extra GPU core that was disabled before in A12X. However, it is the exact same as A12, which also means, it is fabbed on the original 7nm process, not the improved 7nm+ process that A13 is fabbed on. A14 is on the new 5nm process, we don't know the impact of it is yet, it can be faster or it can be more efficient, Apple chooses how to balance them per SoC.
2. iPhone 11 is using A13, which is already 15-25% improvement across the board compared to previous A12 chip in iPhone. Read all of the changes between A12 > A13 here:

3. In the same review, Anandtech mentioned that A13 is actually more power hungry than A12 but not so much to harm it because they also fixed the sustained performance issue while keeping their devices much cooler than any other devices. So, in other words, more core does not mean more heat either, the higher frequency can cause more heat than just having another core. That's why Apple design SoC with various combinations of multiple performance and efficiency cores, instead of being consistent across all of them.
1. Macs will be actively cooled, that has a huge impact of how well it'll work as well. Apple can push the frequency to the max for a longer period of time, which will speed up the single core perf. That's what Intel's Turbo Boost is about. Again, A13 was designed for sustained pref in mind rather than being much faster but they were able to do both.
What's key is the IPC gain, how much work it can do per clock and perf per watt. In this case, A13 has ~15-20% IPC improvement over A12. A14 already is likely to match that. In other words, expect iPad Pro's A14X to be a monster (I can see 30-40% gain over A12X (we already know it'll be a min of 15-20% from A13)) and if that's going to be a monster, imagine what the Macs will be like with active cooling.
Of course, there's a chance Apple will reduce the pref intentionally to boost the GPU and other type of cores instead; which means they may intentionally reduce/limit the frequency/cores in order to focus on the GPU cores instead. Given how much of the OS is now GPU accelerated and how much Metal is improving their software ecosystem, that's a strong possibility.
So, no one will know for sure until it is out.
imagine that becoming A14m with rumored 8p core and 4e core.. thats pretty amazing š³ that should beat out intel i7-10875H..?
