fabrication process
Apple's A14 Bionic chip is based on TSMC's new 5nm manufacturing process. The 7nm A13 bionic chip has 8.5 billion transistors, while the new 5nm A14 chip has the capacity of 11.8 billion transistors. Therefore, 5nm process technology helps to achieve more transistors in the same space. This allows us to have better performance in almost every area. Apple claims the A14 can deliver higher power efficiency, with up to 10 hours of battery life. A 5nm node means a 15% increase in performance and a 30% increase in power efficiency.

CPU performance
Since the A13 chip has the same structure as the A12 (2 4), it is speculated that the core configuration of the A14 chip will change (3 3). But with the A14 chip, we again see a Hexa core setup with 2 4 configurations. However, we got two new generation high-performance cores and four new small, energy-efficient cores. The A13 Bionic, on the other hand, comes with a 24 Hexa kernel setup as well as two high-performance and power-saving cores.
We saw the A13 chip top out at 2.7GHz. As of now, there is no official information on the clock speed of the A14 chip's main core, but an earlier leak suggests a top frequency of 3.1GHz, which is 400MHz higher than the A13.
According to Apple, the A14 Bionic offers a 40% CPU improvement over the A12 Bionic. We already know that A13 is 20% faster than A12. So if Apple uses the same performance metrics tools as previous generations, then we can say that the A14 Bionic will deliver 16% better performance than the A13 Bionic.
