Jump to navigation Jump to search Series of systems-on-a-chip designed by Apple Inc. For the x86-based processor apple chips codename was “M1”, see Cyrix 6×86. The M1 was introduced in November 2020.
The M1 was followed by the professional-focused M1 Pro and M1 Max chips in 2021. The M1 Max is a higher-powered version of the M1 Pro, with more GPU cores and memory bandwidth and a larger die size. Initial support for the M1 SoC in the Linux kernel was released in version 5. The M1 has four high-performance “Firestorm” and four energy-efficient “Icestorm” cores, first seen on the A14 Bionic. The M1 Pro and M1 Max use the same ARM big. The M1 Ultra features a 48- or 64-core GPU.
The M1 uses a 128-bit LPDDR4X SDRAM in a unified memory configuration shared by all the components of the processor. The M1 Pro has 256-bit LPDDR5 SDRAM memory, and the M1 Max has 512-bit LPDDR5 SDRAM memory. While the M1 SoC has 66. The M1 Pro comes in memory configurations of 16 GB and 32 GB, and the M1 Max comes in configurations of 32 GB and 64 GB. The M1 contains dedicated neural network hardware in a 16-core Neural Engine, capable of executing 11 trillion operations per second.
Supported codecs on the M1 include H. The M1 Pro supports two 6K displays at 60Hz over Thunderbolt, while the M1 Max supports a third 6K display over Thunderbolt and a 4K monitor over HDMI 2. The 2020 M1-equipped Mac Mini draws 7 watts when idle and 39 watts at maximum load, compared with 20 watts idle and 122 watts maximum load for the 2018, 6-core Intel i7 Mac mini. After its release, some users who charged M1 devices through USB-C hubs reported bricking their device. A flaw in M1 processors, given the name “M1racles”, was announced in May 2021.
Two sandboxed applications can exchange data without the system’s knowledge by using an unintentionally writable processor register as a covert channel, violating the security model and constituting a minor vulnerability.
