The M4 chip was introduced in May 2024 for the iPad Pro (7th generation), and is the fourth generation of the M series Apple silicon architecture, succeeding the Apple M3. [3] [4] [5] It was followed by the professional-focused M4 Pro and M4 Max in October 2024. [6]
The M3's Unified Memory Architecture (UMA) is similar to the M2 generation; M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14]
The M2 Max is a higher-powered version of the M2 Pro, with more GPU cores and memory bandwidth, and a larger die size. [5] In June 2023, Apple introduced the M2 Ultra, a desktop workstation chip containing two M2 Max units. [6] Its successor, Apple M3, was announced on October 30, 2023.
The M4 is based on the N3E process rather than the N3B process used by the M3 and contains 28 billion transistors. It has three or four performance cores, six efficiency cores and up to ten GPU cores. Apple claims the M4 has up to 1.5x faster CPU performance compared to the M2. [187]
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. [23] The M2 Ultra is a processor combining two M2 Max dies in one package. It is available in the highest-end variants of the ...
The seventh-generation iPad Pro models feature the Apple M4 SoC. iPad Pro colors are available in Silver and a new Space Black, which is a darker version of Space Grey, similar to the M3 MacBook Pro. The device comes with a Tandem OLED display for both the 11 and the 13-inch model. The iPad Pro base model has 256 GB of storage and provides ...
On January 17, 2023, Apple announced the updated 14-inch and 16-inch MacBook Pro models based on the M2 Pro and M2 Max chips. The updated models also include Bluetooth 5.3 and Wi-Fi 6E connectivity, HDMI 2.1, longer battery life, and up to 96 GB of memory with M2 Max models with better speed and performance.
In 2022, the Touch Bar MacBook Pro was updated to feature an Apple M2 chip. The 14-inch and 16-inch MacBook Pros were released in October 2021. Powered by either M1 Pro or M1 Max chips, they are the first to be available only with an Apple silicon system on a chip. These models re-introduced MagSafe, function keys HDMI, an SD card reader, and ...
