Not really. Apple prefers to keep their chippery proprietary, so they aren’t competing for any customers (outside Apple itself of course.)stick more cores, a fan and intel & amd will be seriously shitting themselves.
If this rumour pans out, the resultant computational power will remarkable though. 8 high performance cores, which individually have the highest single thread performance around ensures a solid base, but Apple has done intriguing additions to the ISA as well as included respectable ML processing capabilities.
Also, unaccounted for in the Bloomberg rumours is the memory subsystem. In the formfactor described, one could assume that it would use basically an iPad main memory setup, which in this time frame would imply 128-bit LPDDR5. That in itself would be roughly twice as fast as current desktop systems (outside 4-channel HEDT). An alternative could be HBM, which would extend the memory advantage further.
But even the baseline assumption would be a significant advancement over current systems.
A somewhat odd detail in the rumour, that kind of lends it some credibility is USB-4 being mentioned. I can almost believe that this rumour is based in some kind of reality.
