As you may already know, the Apple’s A15 Bionic chipset is the latest chipset that they are going to use in Apple iPhone 13 models and the iPad Mini 6. This article is written in order to clarify everything you should know about the chipset.

The very first thing you should know about these kinds of chipsets are that they are called SOCSystem on a Chip. Let me explain it to you. Imagine a computer motherboard, and you can notice there are GPU, CPU, and the Memory in different places. In a System on a Chip, those components aren’t separated, they are packed to a one chipset. The architecture of a SOC has both economical and performance values of its own. One of the obvious reasons to develop a chipset design like this is Apple wanted to make a remarkable difference between them and their competitors, in which they succeeded very well.

These types of chipsets have specified parts to do specified jobs. The CPU, the GPU, and the ISP (Image Signal Processor) with the Neural Engine are the three main parts in this Apple A series chipsets. The CPU is basically divided into two major parts called Avalanche and Blizzard with a total of 6 cores (2 Avalanche and 4 Blizzard cores). The CPU frequency is marked as whopping 3223MHz. Even though Apple advertised this A15 Bionic chipset is 50% faster than the competition, researchers have shown that this is actually lot faster than that, like more than 60% faster to be roughly accurate. I think Apple was just being modest.

When talking about the GPU, there are two versions of it. One is that comes in iPad Mini 6, iPhone 13 Pro and Pro Max models which has 5-cores of GPU and is claimed to be 50% faster than the competition. The other version is 4-core version with one core disabled that comes in iPhone 13 and 13 Mini. It is also claimed to be 30% faster than the competition. A powerful GPU helps to drastically improve the overall experience of using an Apple iPhone. There is another feature called Lossy Texture Compression (different from Lossless) which allows to process textures with two times larger resolution than before using the same amount of memory.

At first when Apple introduced A-series processors they were heavily dependent on the GPU, but after they released A11 chipset with something revolutionary called Neural Engine, it all changed. In the simplest words, Neural Engine is something that makes enhance machine learning tasks without utilizing GPU or CPU. Having a whole new part of the chipset to do that one job made it very efficient and power saving than ever. In the A15, the Neural Engine has 16-cores and can do 15.8 trillion operations per second — making it 40% faster than the A14 Neural Engine. The new Cinematic Mode that comes with the Apple iPhone 13’s camera is totally powered with this Neural Engine. With A12 chipsets Apple introduced the Smart HDR feature, which was an obvious fact to put Apple ahead from the competition. With each and every chipset apple designed after the A12, there was a new Smart HDR technology with amazing new features. With the A15 and its ISP, Smart HDR 4 is able to render multiple people in the same shot and can process them separately and individually. To record and save each and every frame you capture with your iPhone without slowing down the process, there is a new NVME based storage controlling system which is again, way faster than any other in the market currently.

Another thing about this A15 is it supports Adaptive Refresh Displays (13 Pro and Pro Max). with the A15’s new display engine and the always on touch controller, it can reduce itself to 10hz when needed — in real time and again can go back to 120hz according to how fast your finger is moving.

In addition to all these things, the very best thing about this A15 Bionic Chipset is, it does all these work with an extended battery life when comparing with the previous Apple iPhone models. Yes, the battery capacity is extended too, but the thing here is to do so much workload, to process such things using more power and still extending the battery life. That is the real impressive thing in this. The stats on battery life are totally overwhelming.

This is basically every basic detail an average iPhone user should know about the A15 Bionic chipset. It is new and it is powerful!
