A15 Bionic vs A14 Bionic – What is the Difference Between the Chips?

Each year, Apple holds three to four events. They are held during the months of March, and during June, with the Worldwide Developers Conference. In the month of September, the event is centered around the Apple Watch and the iPhone.

At times, the maker also has an event during the month of October with the release of the iPad or the MacBook. Due to the pandemic and the current market scenario, we are witnessing a massive shortage of components for manufacturing the chips.

Still, famous makers like Intel, AMD, and Apple are running the show with whatever they have left, not to annoy the consumers. From 2019 onwards, there has been a surge in demand for processors.

In this comparison review, we will be taking a look at two phenomenal chips that are produced by Apple. They are A15 Bionic vs A14 Bionic chip processors. The A15 chip is what you find in the iPad Mini, and it is extremely powerful.

This is what makes the iPad Mini powerful and sellable. Otherwise, we do not think that the iPad Mini would have been on Apple shelves globally at all. It comes with interesting specifications like a more extensive system cache and a new image signal processor.

There is a new display engine, a new Video Encoder/Decoder, and a secure enclave. You can find better compression. We strongly feel that the manufacturer is underselling the performance of its new A15 Bionic chip.

This is because of the in-depth benchmarks and analysis of the iPhone 13 scores that are pointing to having considerable power. You would be delighted to know that there is a hefty improvement on the A14 chip.

A notable thing about Apple here is that during the iPhone 13 release, they compared the model with its competition and not the earlier generation units. Maybe a hint of confidence and little arrogance.

But that is what you need when you want to rule the market. The A15 Bionic chip is more than 50% quicker than the leading rival chips. Besides, it has a 30% better graphical performance on the four-core GPU, which is almost more than 50% for the five-core unit.

This goes to show how much it has improved on the A14 Bionic chip. The A14 Bionic chip, too, comes with decent features infused in it. You can find a comprehensive range of specifications that make it still operate in the market.

As in the past, we have seen, merely speed won’t tick all the requirements. You need to be able to put in more than just that. Let us read this review to find out the architecture, performance, pros & cons of both chips to understand them better. We have mentioned the winner at the end of the post.
