Apple spent a large part of today’s announcement event to talk about the A13 Bionic chip, the fastest CPU and GPU ever featured inside a smartphone, just like what it has done in the last three years. However, if you care about iPhone’s battery life, this year’s announcement is something you should pay attention to.
To back up its statement that the A13 Bionic is the fastest GPU and CPU ever, Apple showed a rather vague graph on stage for comparison.
Performance aside, Apple also said that the new chip is 40% more power-efficient, helping to prolong iPhone 11 Pro’s battery life by up to four hours and that of iPhone 11 Pro Max by five hours. The chip features thousands of clock gates and hundreds of voltage gates to prevent parts of the chip to consume power when they are not in use.
This much power efficiency is possible amidst the 8.5 billion transistors and the 20% boost in the performance. According to Apple, the chip also has the most machine learning performance. The A13 Bionic chip can do 1 trillion operations in one second and “6x faster matrix multiplication,” courtesy of an eight-core neural engine.
That machine learning is used in Apple’s newly-introduced iPhone 11 to improve the images. That technology also makes it possible for users of the new phone to record 4K videos with HDR, and at 60 fps.
Like the A11 Bionic and A12 Bionic chip before it, the A13 Bionic has four “efficiency” CPU cores and two “performance” CPU cores. The A11 has a three-core GPU while the A12 has a four-core, and this year, we still see four GPU cores just like 2018's.
