Apple M1 Chip: A Brief Overview of the Mighty Heart of MacBook

The M1 is Apple's first system-on-a-chip (SoC) designed specifically for the Mac, marking the beginning of the company's transition away from Intel processors, which it has used in its Macs since 2006.

The M1 is an “system on a chip” that integrates a central processing unit (CPU), a graphics processing unit (GPU), unified memory architecture (RAM), a neural engine, a secure enclave, a solid-state drive controller, an image signal processor, encode/decode engines, and a Thunderbolt controller with support for USB 4 – all of which power and drive the Mac.

Apple's effort to integrate these processors is why its M1 chip is faster and more power-efficient than earlier Intel CPUs. Before Apple Silicon, Macs used a variety of CPUs, I/O, and security chips. The M1's unified memory architecture, which allows all the technology to access the same data without switching between pools of memory, is also important.

What makes the M1 stand out from similar chips? In this article, we will delve into the key aspects of its design, including its CPU, GPU, and memory architecture.

Central Processing Unit (CPU)

The M1 chip has an eight-core CPU with four high-performance cores and four high-efficiency cores. The high-performance cores are optimized for single-threaded workloads that require a lot of power.

With their four powerful cores, the M1's machines can outperform even the priciest 16-inch MacBook Pro in multi-threaded tasks. And, with their four high-efficiency cores handling less demanding tasks like web browsing using just a tenth of the power, battery life is extended.

GPU stands for Graphics Processing Unit.

The M1 includes an eight-core (or seven-core in some base versions) GPU designed by Apple. Each GPU core consists of 16 execution units, each of which contains eight arithmetic logic units (ALUs). Apple claims that the M1's GPU can run up to 24,576 threads simultaneously and delivers up to 2.6 teraflops of floating-point (FP32) compute. It has a total of 128 execution units, or 1,024 ALUs.

Memory

The CPU cores share an M1, and there's a single 128-bit LPDDR4X SDRAM controller. The system-in-package (SiP) design allows the RAM to be placed side by side with the SoC. It comes in 8 GB and 16 GB memory configurations.

Battery life

The M1 delivers dramatically faster performance while using far less power than any Mac processor that came before it.
M1-powered Macs have up to twice the battery life of their predecessors. The 13-inch MacBook Pro has the best battery life of any Mac ever – up to 20 hours. That's twice what the previous model offered.

Built from the ground up for the M1 chip, macOS Big Sur takes full advantage of its power and capabilities to deliver massive performance gains, extended battery life, and an even stronger layer of security.

Apple M1 Chip Speed

Its CPU is up to 3.5 times faster than the Intel CPUs in previous Macs, its graphics processor is six times faster, and its machine-learning capabilities are 15 times greater. The M1's CPU is twice as fast as the most recent PC laptop CPUs, while consuming only a quarter of the power. And the M1 incorporates a host of powerful custom technologies.

Comparison between the MacBook M1 chip, M1 Pro chip, and M1 Max chip

Apple's MAC laptops utilize the M1, M1 Pro, and M1 Max chips, granting them unparalleled performance compared to other laptops. However, do you know the differences between these three? We'll present them clearly in a table.

Apple's M-series chips, also made by TSMC, the same foundry that produces its A-series chips, come in three flavors: M1 Max > M1 Pro > M1. Prices rise with performance.

Which Apple products use the M1 chip?

Many of Apple's leading products now run on its original chip, the M1. Here is what that means for the company's product line.

Product Name
MacBook Air (M1, 2020) - Base model with 7-core GPU
Mac Mini (M1, 2020)
MacBook Pro (13-inch, M1, 2020)
iMac (24-inch, M1, 2021) - Base model with 7-core GPU
iPad Pro, 11-inch (5th generation) (2021)
iPad Pro, 12.9-inch (5th generation) (2021)
iPad Air (5th generation) (2022)

Products with the M1 chip offer better value for money than those with the M1 Pro and M1 Max chips. If you're looking for a smooth and affordable Apple experience, these are solid choices.
