The A13 Bionic chip has been created with a focus on machine learning to boost performance while offering excellent power efficiency. Its neural engine has 8 cores that are 20% faster, consuming 15% less power than the A12 Bionic. Whereas the machine learning accelerators offer 6x faster matrix multiplication, making the CPU capable of performing 1 trillion operations per second.
One of the ways Apple lowered the power of the A13 Bionic chip is by building on 2nd Generation 7nm fabrication process, meaning the A13 Bionic can fit 8.5 Billion transistors, up from 6.9 billion on the A12 Bionic.
While comparing the CPU and GPU features against A12 Bionic chip, Apple claims these statistics:
A13 Bionic CPU features
Two high-performance cores:
20% faster, 30% less power
Four efficiency cores:
20% faster, 40% less power
A13 Bionic GPU features
20% faster, 40% less power
We have heard similar claims before, let's compare what apple said about previous chips.
A12 Bionic release (iPhone XS and XS Max)
'A12 Bionic features a six-core fusion architecture with two performance cores that are up to 15 percent faster, four efficiency cores that are up to 50 percent more efficient, a four-core GPU that is up to 50 percent faster'
A11 Bionic release (iPhone X and iPhone 8)
'A11 Bionic, the most powerful and smartest chip ever in a smartphone, features a six-core CPU design with two performance cores that are 25 percent faster and four efficiency cores that are 70 percent faster than the A10 Fusion, offering industry-leading performance and energy efficiency.'
A10 Fusion release (iPhone 7, 2016)
'The A10 Fusion's CPU now has four cores, seamlessly integrating two high-performance cores that run up to two times faster than iPhone 6, and two high-efficiency cores that are capable of running at just one-fifth the power of the high-performance cores. Graphics performance is also more powerful, running up to three times faster than iPhone 6 at as little as half the power, enabling a new level of gaming and professional apps.'
Each year, we see brand-new performance increases, and it all looks very good. But, it makes me question, does your new iPhone really feel much faster and does the battery really last for many more hours? I'll leave that thought with you.
