The A12X and A12Z feature an Apple-designed 64-bit ARMv8.3-A octa-core CPU, with four high-performance cores called Vortex and four energy-efficient cores called Tempest. [4] [1] The Vortex cores are a 7-wide decode out-of-order superscalar design, while the Tempest cores are a 3-wide decode out-of-order superscalar design.
The internal codenames for the CPU cores of Apple silicon A series and M series chips are named after islands, with the cores named after wind and weather patterns. [68] Apple A6 and A6X – Bali, with Swift cores; Apple A7 – Alcatraz, with Cyclone cores; Apple A8 – Fiji, with Typhoon cores; Apple A8X – Capri, with Typhoon cores

Upgrades from the second generation iPad Pro include the more powerful A12X Bionic processor, storage capacity up to 1 terabyte [2] and the larger display of the 11 inch model (upgraded from a 10.5 inch model). The third generation iPad Pro also premiered a new design, with a screen that covers more of the front face, and has rounded corners.
The Apple A12 SoC features an Apple-designed 64-bit ARMv8.3-A six-core CPU, with two high-performance cores called Vortex, running at 2.49 GHz, and four energy-efficient cores called Tempest. [4] [5] The Vortex cores are a 7-wide decode out-of-order superscalar design, while the Tempest cores are a 3-wide decode out-of-order superscalar design.
Also, it can deliver the same CPU performance of the A16 Bionic chip while consuming 30% less power. [7] [8] The A18 Pro is up to 15% faster in CPU performance than the A17 Pro chip, and it can deliver the same CPU performance of A17 Pro chip while consuming 20% less power. Apple claims the A18 Pro chip has larger caches than the non-Pro A18 ...
In this situation, it usually makes sense to compile Thumb code and hand-optimise a few of the most CPU-intensive sections using full 32-bit ARM instructions, placing these wider instructions into the 32-bit bus accessible memory. The first processor with a Thumb instruction decoder was the ARM7TDMI. All processors supporting 32-bit instruction ...
The M2 can be configured with up to 24 gigabytes of RAM and 2 terabytes of storage. It has 8 CPU cores (4 performance and 4 efficiency) and up to 10 GPU cores. The M2 also increases the memory bandwidth to 100 GB/s. Apple claims CPU improvements up to 18% and GPU improvements up to 35% compared to the previous M1. [185]
