The Apple M1 It is the first System-on-a-chip (SoC) -based ARM designed by Apple Inc. for its line of Macintosh computers. Appears on MacBook Air (M1, 2020), Mac mini (M1, 2020), y el MacBook Pro (13-inch, M1, 2020).It is the first personal computer chip built using a 5nm process. Apple claims it has the world’s fastest central processing unit (CPU) “in low-power silicon” and the world’s best CPU performance per watt.
The M1 has four high-performance and four low-power cores (referred to as “e-cores” or “high-efficiency”) cores, providing a configuration similar to ARM big.LITTLE.This combination enables optimizations in power usage that are not possible with Apple-Intel architecture devices. Apple claims that low-power cores use one-tenth the power of high-performance cores. The high-performance cores have 192 kB of instruction cache and 128 kB of data cache and share a 12 MB L2 cache; The low-power ones: 128 kB of instruction cache, 64 kB of data cache and share a 4 MB L2 cache.
El M1 utiliza 3733 MHz LPDDR4X SDRAMIn a unified memory configuration shared by all processor components. The SoC and RAM chips are assembled together in a system-in-a-package design. 8GB and 16GB configurations are available.
The M1 integrates an Apple-designed eight-core (seven on some models) graphics processing unit (GPU) and dedicated neural network hardware on a 16-core Neural Engine. Other components include an image signal processor (ISP), NVMe storage and Thunderbolt 4 controllers, and a Secure Enclave.
Dynamic binary translation technology enables M1-equipped products to run software built for Intel x86. CPU.
