The A16 Bionic GPU got ray tracing support, but ambitious Apple engineers found many flaws in previous versions

Apple’s A16 Bionic GPU has been said to be more capable than the commercial unit that powers the iPhone 14 Pro and iPhone 14 Pro Max. Unfortunately, one of the reports claims that the company’s engineers did not anticipate some problems, which led to the scrapping of an earlier prototype with ray tracing support.

The previous A16 Bionic experienced massive power draw, resulting in poor battery life and eventual thermal throttling

Although the A16 Bionic GPU had a performance improvement of about 28 percent over the one in the A15 Bionic in AnTuTu, the previous version could have been much better, according to the info. MacRumors reported that Apple engineers wanted to incorporate several features into the graphics processor, including support for ray tracing, which would have greatly increased visuals in mobile games that supported this option.

Unfortunately, engineers ran into some formidable obstacles in their quest to create the most capable GPU ever in an iPhone. Like any other smartphone, iPhone needs a battery to run and needs an efficient SoC to not only provide extended screen time but also to manage heat dissipation effectively.

While ray tracing support would be a nice touch, it would come at the expense of massive power draw, increased temperatures, and drain on battery life. Going back to the drawing board, Apple engineers had to make another prototype that differs from the A15 Bionic while providing some notable improvements over the A16 Bionic.

These issues eventually forced Apple to restructure its entire graphics-processing team, which meant some managers had to be removed from the development of the A16 Bionic to work on something else. Naturally, this may not have been properly met by the company’s employees, which may be the reason for their departure. Over the years, Apple has lost some key figures that were essential to the company’s dominance of the smartphone SoC space.

This was evident when last year’s A15 Bionic didn’t make huge performance gains over the A14 Bionic, and now, history seems to be repeating itself. Although the A16 Bionic is still the fastest smartphone SoC at this time, the loss of important talent will allow companies like Qualcomm and MediaTek to take advantage of this opportunity. So far, the Snapdragon 8 Gen 2 hasn’t been able to beat the A16 Bionic in single-core and multi-core scores, but the performance gap has shrunk significantly.

This may mean we may not see any massive power efficiency and performance gains when the A17 Bionic launches next year, but let’s not get too ahead of ourselves.
