Apple introduces the A13 Bionic for the iPhone 11


Apple is announcing new iPhone models today. The iPhone 11 uses an Apple A13 Bionic system-on-a-chip. It is a nice improvement over the A12 Bionic in the iPhone XR, XS and XS Max.

But how much faster exactly? Apple first said it is making the fastest GPU and CPU for a smartphone. It then showed two charts with no X-axis — those charts weren’t helpful. But later in the conference, Apple shared some details about A13 Bionic performance.

VP of Silicon Engineering Sri Santhanam shared some details about the A13 Bionic. Everything has been optimized for machine learning. The CPU can do 1 trillion operations per second. The CPU, GPU and Neural Engine should work better together when it comes to performing machine learning tasks.

“The iPhone 11 Pro is the best machine learning platform in any smartphone” Santhanam said.

When it comes to architecture, Apple is using 7nm transistors (like on the A12 Bionic), and there are now 8.5 billion transistors — that’s a huge update compared to the A12 Bionic, which had 6.9 billion transistors. The A13 Bionic still has four high-efficiency cores and two high-performance cores.

The two high-performance cores are 20% faster than previous high-performance cores and consume 30% less battery. The four high-efficiency cores are 20% faster and consume 40% less power.

The GPU has been optimized for Metal. It is 20% faster and consumes 40% less power. And, finally, the neural engine has eight cores and is 20% faster while consuming 15% less power.

I'm a 50 year old PLC programmer from Burnley, UK. I severed my time as an electrician in the baking industry and soon got involved with the up and coming technology of PLC's. Initially this was all based in the Uk but as the years went by I have gradually worked my way around the globe. At first it was mainly Mitsubishi with a bit of Modicon thrown in but these days the industry leaders seem to be the Allen Bradley range of PLC and HMI’s.
