From Samsung to the Bionic A17, the iPhone’s processor journey is quite mesmerising. Apple needs no introduction! The brand is well-known for its sleek products, proprietary technology, and cutting-edge, industry-leading product designs.

Generally, most companies, like Samsung, HP, etc., outsource chip designing and other things. However, Apple prefers to keep things in-house whenever possible. And chips found in iPhones, iPads, and other iOS devices are no exception.

Companies like Microsoft, HTC, and Samsung rely on Qualcomm and Intel for their product chipsets. However, things at Apple are pretty different. Apple has a team of engineers that exclusively work for iOS devices (Apple’s proprietary designs).

How did it start?

Designing their chipset started in 2008 when Apple bought a semiconductor company, PA Semi. However, technically, the thing is different. Apple started designing their chipset earlier than that. Before the Apple “A” series chipset was introduced, the company designed various SoCs in early iPhone and iPod touch versions. These were majorly manufactured by Samsung.

Since its inception, Apple has focused on its long-term vision for iPhone. They never tried to push products or features into the market as soon as possible. Therefore, designing and manufacturing their chipset is always within their goals. The reason is that they know no one will be able to supply them with the right chipset.

Therefore, they have done a series of talent searching, hiring, polishing, and acquisitions and built their team. And do you know what its result was? They built their first SoC – the A4 SoC in 2007, which powers the first iPad. And, from there, the journey continues.

Let’s track the iPhone’s processor journey in the next section.
