The semiconductor business is not easy. The M-series chip makes sense because you can share it between mobile and desktop machines. The A-series and the M-series are very closely related. Once you start to enter the high-end server market you have to add more IP, change the processor interconnect, topology, and increase the transistor count on the IP you already developed. This leads to the necessity to design another line of processors which needs additional design, verification, validation, software development, etc that you won't be able to share with your profitable chips. You then need to ask, is there really a market for this? When Apple used 3rd party CPUs they outsourced the cost of that server development work, the 3rd party Intel already had a large market for their Xeon class chips so development costs were spread across customers. The business made sense. Let's face it, the Pro side of the business is tiny relative to the mobile market and it does not make business sense.
