The Apple A6X is a 32-bit system-on-a-chip (SoC) designed by Apple Inc., part of the Apple silicon series. It was introduced with and only used in the 4th generation iPad , on October 23, 2012. It is a high-performance variant of the Apple A6 and the last 32-bit chip Apple used on an iOS device before Apple switched to 64-bit .
The iPad (4th generation) [15] (marketed as iPad with Retina display, [16] colloquially referred to as the iPad 4) [17] [18] is a tablet computer produced and marketed by Apple Inc. Compared to its predecessor, the third-generation iPad, the fourth-generation iPad maintained the Retina Display but featured new and upgraded components such as the Apple A6X chip and the Lightning connector ...
Both have 12 CPU cores (8 performance and 4 efficiency) and a 16-core Neural Engine. The M2 Pro and M2 Max have a 19-core and 38-core GPU, and a 256-bit and 512-bit LPDDR5 memory bus supporting 200 and 400 GB/s bandwidth respectively. Both chips were first introduced in the MacBook Pro in January 2023.
The Apple A7 is a 64-bit system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series. It first appeared in the iPhone 5S, which was announced on September 10, 2013, and the iPad Air and iPad Mini 2, which were both announced on October 22, 2013. Apple states that it is up to twice as fast and has up to twice the graphics ...
A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ...
iOS 10 is the final version of iOS that supports 32-bit devices, including the iPhone 5, iPhone 5c, and the fourth-generation iPad, as its successor, iOS 11, drops support for those models. iOS 10 is also the final iOS version to support 32-bit applications.
The Apple A8X is a 64-bit SoC introduced at the launch of the iPad Air 2 on October 16, 2014. [75] It is a high performance variant of the Apple A8 . Apple states that it has 40% more CPU performance and 2.5 times the graphics performance of its predecessor, the Apple A7 .
