A13 Bionic Was Made With ‘Performance per Watt’ in Mind, Says Company’s Hardware Engineer

During its September 10 iPhone 11 keynote, Apple marketed its A13 Bionic as the fastest and most efficient mobile chipset to power handsets. Looking at the performance gap between SoCs running in competing Android smartphones, we’d definitely agree with the California-based giant here. Now, in the latest interview with Apple’s Senior Vice President of Worldwide Marketing and hardware engineer Anand Shimpi, both individuals take a deeper dive into what makes the A13 Bionic so special.

In a feature by WIRED, Schiller told the publication that the biggest performance increases this year that customers can witness from the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max is text-to-speech. According to the Apple executive, this was all made possible thanks to machine learning and the neural engine running in the A13 Bionic.

Kirin 990 Performance Still Lags Behind A13 Bionic in Leaked Benchmark

“We've enhanced our iOS 13 text-to-speech capabilities such that there is much more natural language processing, and that's all done with machine learning and the neural engine.”

According to Shimpi, when Apple’s dedicated team gets down to designing an A-series chip, it focus on both performance and efficiency. This time, with the A13 Bionic, they’ve dialed up those efforts. Additionally, in previous benchmark leaks, the iPhone 11 and iPhone 11 Pro have shined considerably when it comes to single-core performance results. Keep in mind that the six-core processor of the A13 Bionic features just two performance cores, while the remaining are all about efficiency, and the fact that this silicon is able to trump chipsets like the Snapdragon 855 Plus and Exynos 9825 is impressive.

“We talk about performance a lot publicly. But the reality is, we view it as performance per watt. We look at it as energy efficiency, and if you build an efficient design, you also happen to build a performance design.”

Rumored iPad Pro Refresh for This Year Could Surpass the A12X Bionic’s Performance and Combine the iPadOS Experience to Create a New Platform for Various Customers

The interview also states that the team behind Apple’s superiority in the mobile silicon game will continue to monitor how apps are being used on iOS devices so they are able to optimize future chip designs. This performance is not just evident in the latest iPhones but last year’s iPad Pro range, where we witnessed a new plateau of results, especially for something that’s as portable, thin, and lightweight as a tablet. Synthetic benchmarking results showed that the iPad Pro is only a tad bit slower than the six-core i7-fueled MacBook Pro.

If we get another iPad Pro refresh this year, we believe Apple will take it up another notch in performance with the introduction of the A13X Bionic. Coming back to the A13 Bionic, previous reports stated it was engineered using TSMC’s superior N7 Pro architecture, and the benefits can be seen in both performance and staggering improvements in the iPhone 11 series’ battery life.
