In 2010, Apple unveiled its first proprietary A4 chip, which was used in the first generation iPad. A few months later, the iPhone 4 arrived with the same chip. It is worth mentioning that this chip was produced by Samsung. Samsung and Intrinsity played a key role in designing an improved model of the Cortex-A8 core, known as the Hummingbird. A few months later, Apple acquired Intrinsity, an important step in the company's chip design efforts.

A few years later, it was the turn of the important company PA Semi. Thanks to these measures, Apple had enough specialists to design powerful chips. In 2011, the second generation iPad with the A5 chipset was introduced. This chipset also did not use dedicated cores. The third generation came with an improved version of the chip called the A5X. In the following years, the trend of using the X suffix for iPad chips continued.

These chips are mostly similar to chips They were used in iPhones, but offered more power than the models in question. Tablets are larger than phones, so they use a larger battery and have more heat dissipation power; So tablets can handle more powerful chipsets.

The A6 chipset was first introduced with cores designed by Apple. The A6X chip was also used for the iPad, which had only one more core for the GPU than the original model. Two years later, it was the turn of the A8X, which had more to say about both the processor and the GPU than the original model. Apple once again used the same processor for the A9X as the regular model, but then all the AX chips came with more powerful processors than the regular model.

In 2016, the A10 chip used the big.LITTLE architecture for the first time. The chip used two powerful Hurricane cores and two low-power Zephyr cores. A year later, the A10X was introduced, which used three powerful cores and three low-power cores, while also doubling the number of GPU cores. It does not change much. Therefore, for the A12X chip, the number of low-power cores did not change compared to the regular model, but the powerful cores increased from 2 to 4. The GPU also received a substantial upgrade to 7 cores, and in 2020 the A12Z was introduced with an 8-core GPU.

In 2020, after years of using Intel chips, Apple began to use proprietary chips for Launched Mac computers. Instead of the usual x86 architecture, Apple has used the same Arm architecture used for iPhones and iPads for the chips of these computers.

The M1 chipset, the first generation of these chips, is based on the A14 chip used in the iPhone 12 series and the fourth generation iPad Air. Following in the footsteps of the iPad chip, the M1 chipset uses more CPU-based processors and GPUs than the A14. Also, like the A12X, Apple has not changed the number of low-power cores. At least as a builder of it. Some time ago, Apple unveiled the M2 chipset, which is based on the A15 used in the iPhone 13 series.

It seems that in the near future we will see the unveiling of the Pro, Max and Ultra models of this chip. These models offer either more features in terms of processor or GPU or both. In general, after years of experience in proprietary chips, Apple has now been able to apply this knowledge to its computers. We have to see if Apple can significantly increase the attractiveness of these chips in the future.
