Apple M1 Max

The Apple M1 Max is an ARM-based (SoC) designed by Apple. Developed for the Mac line of computers, the M1 Max and the smaller M1 Pro were introduced by Apple during a special event on October 18, 2021 for the 14 and 16-inch MacBook Pros.Apple Event — October 18 by Apple, YouTube. 2021-10-18. In March 2022, it also became an option for the base configuration of the Mac Studio.Apple unveils all-new Mac Studio and Studio Display, Apple Inc. 2022-03-08.
==Specifications==
The M1 Max is manufactured by TSMC to Apple's design specifications. The 432 mm2 contains 57 billion transistors that are fabricated through a . Dynamic RAM (DRAM) is built onto the package and is shared with memory bandwidth of up to 400GB/s through Apple's unified memory architecture (UMA) to eliminate the need to copy data from the CPU to GPU, which are both part of the package.Introducing M1 Pro and M1 Max: the most powerful chips Apple has ever built, Apple Inc. 2021-10-18.Apple Announces M1 Pro & M1 Max: Giant New Arm SoCs with All-Out Performance by Andrei Frumusanu, AnandTech. 2021-10-18.
The 10-core CPU (same as in the M1 Pro) contains eight high-performance cores and two high-efficiency cores, similiar to the architecture used by mobile devices for power efficiency. However, the GPU contains 32 cores for graphics. In some mid-level configurations, eight of the GPU cores are deactivated, indicating the practice of .MacBook Pro 14- and 16-inch - Technical Specifications, Apple Inc. Archived 2021-10-18. The Neural Engine contains 16 cores for machine learning performance. The Media Engine accelerates codec processing at low power with twice the performance of the M1 Pro. A Thunderbolt 4 and USB4 controller is included on the chip. It also includes its own Secure Enclave.
==Performance and compatibility==
Apple advertises up to 70% faster CPU performance than the preceding M1 and quadruple the GPU performance. Compatibility with Intel software is provided through Rosetta 2 emulation, with a reported performance hit of about 21-22%, but still exceeding the speed of Apple's Intel-based models.I love that Apple’s M1 can easily shrug off a 20% performance hit just to emulate x86_64 and still be faster than the Intel chips in the rest of Apple’s lineup by Steve Troughton-Smith, Twitter. 2020-11-15.Apple Silicon M1 Emulating x86 is Still Faster Than Every Other Mac in Single Core Benchmark by Frank McShan, MacRumors. 2020-11-15. The first operating system from Apple to support the M1 Max and M1 Pro is macOS Monterey, which can also natively run iPadOS applications on the M1 processor family.
===Limitations===
DRAM must be ordered in advance in 32 or 64 GB configurations as they are part of the M1 Max's SoC package.
===UltraFusion===
On March 8, 2022, Apple senior VP of hardware technologies Johny Srouji revealed that the M1 Max included a previously undisclosed interconnect feature called UltraFusion, which allowed two of them to be packaged together to create the Apple M1 Ultra, with twice the computing power.Apple Event — March 8 by Apple, YouTube. 2022-03-08.Apple unveils M1 Ultra, the world’s most powerful chip for a personal computer, Apple Inc. 2022-03-08.
