Everything you need to know about all Apple custom chips

Apple has been developing its own custom silicon for iPhones, iPads, Apple Watches, and many other products for several years. It has more than a decade’s worth of experience, and it also has partnerships with leading semiconductor companies to produce these chips. Over the past few years, the company decided to take matters into its own hands, and it started to reduce using chips from companies such as Intel and AMD.

With the introduction of the new M series of chips, Apple completely changed the game for Mac laptops, desktops, and even the iPads. Apple controls much of its infrastructure, and it’s one of the most valuable companies to take matters into its own hands. Having this much power allows Apple to create more powerful chipsets which are more efficient than the ones offered by the competition.

Optimizing devices, developing hardware, and creating a platform where these products can communicate with each other provides users with an ecosystem that they can rely on and trust. We deemed it necessary to help our audience stay informed about the wide variety of chips that Apple has developed over the years; therefore, we created this post to help everyone understand the history and the key specifics of previous, current, and future Apple chips.

Apple U-Series

The Apple U series chip implements the ultra-wideband radio, and it allows Apple devices to locate products, such as iPhones, AirPods, and the AirTag. The U chip communicates with other Apple devices using the ultra-wideband that uses high-frequency, low range, radio signals to locate devices accurately. The chip lets users find gadgets and smartphones to a highly accurate level, and it’s more precise than traditional GPS and Bluetooth trackers.

These Apple devices use the U1 Chip:

• AirTag
• Apple Watch Series 6 and later
• HomePod and HomePod mini-series
• iPhone 11 and later series (excluding the iPhone SE series)

Apple AirTag

The Apple AirTag lets you easily keep track of your devices, pets, bags, and other items using the Find My app. It’s easy to set up, and it works on all Apple devices, such as iPhones, iPad, and Macs.

Apple W-Series

The Apple W series of chips are used in wireless devices, such as AirPods (first generation) and Beats headphones (Beats Flex, Beats Solo3, Beats Studio3, BeatsX, Powerbeats3), and wireless earbuds. The “W” stands for “wireless”. It’s also worth noting that the Apple Watch Series 3 also relied on the W2 chip to improve Wi-Fi and Bluetooth efficiency, and it was integrated into the Apple S3 chip, which powered the smartwatch. The Apple Watch Series 4, Series 5, Series 6, SE, Series 7, Series 8, and later the Apple Watch Ultra relied on the improved Apple W3 chip to improve connectivity and support Bluetooth 5.0 and 5.3.

Apple H-Series

The Apple H series of chips are mainly used in headphones and other wireless audio devices. The “H” stands for “headphones”. The Apple H1 chip was first introduced in 2019, and it was used by the AirPods 2, AirPods 3, and later in Beats products, such as the Powerbeats Pro, Beats Solo, AirPods Pro (1st gen), and more. The AirPods Max was unveiled in 2020, and it also relied on the H1 chip to manage connectivity, firmware, and Bluetooth connection.

The AirPods Pro (2nd Gen) was announced in September 2022, and it came with the new H2 chip that introduced support for Bluetooth 5.3. The recently unveiled Beats Studio Buds+ earbuds are some of the first Beats devices to lack the H and the W series of chips to provide better support for Android users.

  The Apple AirPods Max is powered by the Apple H1 chip in each earcup, and it contains eight microphones to cancel out noise. It’s one of the best wireless headphones for Apple users, and it can last for up to 20 hours on a single charge.

Apple S-Series

The Apple S series of chips are used in Apple Watches, and the Apple S1 chip was released on September 9, 2014 alongside the first-generation Apple Watch. Apple usually unveils a new version of S series chip alongside the new Apple Watch, and at the time of writing this, Apple is currently at Apple S7 generation, which includes a 64-bit processor. The chip controls the processor, storage, memory, connectivity, and other components to ensure the watchOS can communicate with other Apple devices, such as iPhones, to handle notifications, messages, calls, etc.

Each new generation of S chip usually includes several performance improvements over its predecessor. Apple sometimes integrates new chips, or sensors inside to improve tracking and offer more measurement methods for users to track their health and activities.

The HomePod mini also relies on the Series 5 chip to power the device and ensure it can connect and communicate with other Apple devices. The HomePod (2nd Generation) relies on the Apple S7 series chips, and it was announced

Apple T-Series

The Apple T series of chips ensure that Mac devices aren’t tampered with, and it allows Mac machines to boot up securely. The chips also process and encrypt biometric information, such as Touch ID fingerprints, and it protects the microphone and the FaceTime camera from hacking.

Apple released two versions of the T chip over the years, the Apple T1, and the Apple T2. The T1 chip was an ARMv7 chip, and it was used in the 2016 and 2017 MacBook Pro laptops to ensure secure boot and protect encryption keys and store Touch ID biometric information. The T2 chip was first released with the iMac Pro 2017 machine, and it used a 64-bit ARMv8 chip that ran bridgeOS 2.0. It protected the storage drives and was used in Mac computers until the 13-inch MacBook Pro, the Early 2020 version.

Apple is no longer using the T series of chips to protect its machines from tampering and hacking, since the new M series of SoCs have the processes built-in to protect the internals.

Ever since Apple decided to use its own custom silicon (M series) chips to power its machines, the process, and security methods are built into the SoC itself; therefore, there is no longer a need to keep and use a dedicated chip.

• 

  Apple Studio Display

  The Apple Studio Display is likely an overall for most people, but its price might be justified for professionals, and those who appreciate the exceptional build quality, excellent accuracy, and great compatibility with Apple products. 

Apple started including its own chips back in 2007, when it revealed the first iPhone. It included a 412MHz single-core ARM11 chip, and it was manufactured by Samsung using the 90 nm process. The first generation of iPod Touch also used this very same SoC to handle tasks and power the device. Apple made four chips before switching over to the A-series.

While Apple develops its own chips to power the devices, the iPhones and iPads still rely on many other chips and modems to handle connectivity such as 5G, Wi-Fi, and even storage is made by other companies such as Samsung. Fun fact: The Face ID chip was introduced with the iPhone X back in 2017, powered by the Apple A11 Bionic chip, produced on the 10nm process.
