Apple's Internal Hardware Team Is Working On Modems That Will Likely Replace Intel (arstechnica.com)

An anonymous reader quotes a report from Ars Technica: Apple will design its own modems in-house, according to sources that spoke with Reuters. In doing so, the company may hope to leave behind Intel modems in its mobile devices, which Apple has used since a recent falling out with Qualcomm. According to the sources, the team working on modem design now reports to Johny Srouji, Apple's senior vice president of hardware technologies. Srouji joined Apple back in 2004 and led development of Apple's first in-house system-on-a-chip, the A4. He has overseen Apple silicon ever since, including the recent A12 and A12X in the new iPhone and iPad Pro models.

Before this move, Apple's modem work ultimately fell under Dan Riccio, who ran engineering for iPhones, iPads, and Macs. As Reuters noted, that division was heavily focused on managing the supply chain and working with externally made components. The fact that the team is moving into the group focused on developing in-house components is a strong signal that Apple will not be looking outside its own walls for modems in the future. In recent years, Apple has been locked in a costly and complex series of legal battles with Qualcomm, the industry's foremost maker of mobile wireless chips. While Apple previously used Qualcomm's chips in its phones, the legal struggles led the tech giant to turn instead to Intel in recent iPhones.

    I'll be interested in seeing how this turns out. Apple has had great success with their ARM SoC design, and I don't doubt they can design a modem and baseband, but will they be able to design something that provides similar performance to what Qualcomm produces. Intel hasn't had a lot of success outside of x86, so I don't know how much of their failings can be pinned on the company, but rolling your own hardware is no small task.

      Apple has had great success with their ARM SoC design,

      I suspect a large part of this success is not due to technical superiority, but getting priority at newer (lower power) fabs due to Apple's large volume of orders. Their Ax processors were the first to use the smaller lithography available from fabs, which meant a corresponding reduction in power consumption for the same level of performance (or alternatively, better performance at the same power consumption). Back when they still used Samsung as a fab, even Samsung Semiconductor prioritized Apple's order ahead of Samsung Mobile's own Exynos SoCs.

      If you remember the whole mess over the Nvidia Maxwell GPUs (the 8xx and 9xx series) not performing as expected, it's for the same reason. Nvidia assumed they'd be able to use TSMC's new 16nm and Samsung's new 14nm processes to manufacture Maxwell, and designed Maxwell assuming the thermal limits of those lithographies. But Apple's order for Ax processors bumped them down in the queue. That forced Nvidia to manufacture Maxwell on 28nm, leading it to overheat until they redesigned it with fewer cores, meaning it under-performed. It was so bad they actually re-used the Kepler architecture (700x series) for their higher-end mobile 8xx GPUs, since it was already optimized for the thermals of 28nm. Pascal (10xx series) was manufactured on 14nm and 16nm as expected, and was a success.
