Apple Silicon: Speed Benefits For Developers With The New ARM Architecture?
What Apple has been doing in the mobile sector for years is reaching the Mac systems: The Macbook Air has recently been running on its system-on-a-chip with ARM architecture, which Apple has dubbed the M1. This article will clarify what it can do (or not).
Technical Information About The M1 Chip
The M1 has eight cores. Four fast, called “Firestorm, “and four slow, called “Icestorm. “The Firestorm centers each have their store (192 KB L1 and 128 KB L1D) and a common L2 reserve (12 MB). The Ice Storms share a 4-megabyte L2 cache. In addition, there is Apple’s “Fabric,” which connects the components, including the CPU and cache, the “Neural Engine,” a GPU, and the RAM controller, which can connect up to 16 gigabytes of memory.
This is an ARM 64-bit architecture. Natively only runs ARM64 code. For x64 or x86, a translation layer, which in this case is called “Rosetta 2”, is necessary. The M1 can draw up to 15 watts for a short time but is designed for an average of 10 watts. This low energy consumption also enables completely passive cooling systems: This is a real mobile CPU that was previously used more in smartphones than in notebooks.
How Fast Is The M1?
In native mode, the combination of CPU and GPU is blazingly fast, and in single-core mode comes dangerously close to a Core i7-1185G7, which has twice the power consumption. It can even outrun it entirely in multi-core mode and is around 10% faster. However, if you have to rely on Rosetta, it quickly becomes sobering because the intermediate layer robs the CPU of almost a third of its performance, including overhead.
Regarding GPU, Apple’s SoC is about as fast as a mid-range graphics card from the penultimate generation, i.e., Geforce 1050 or Geforce 1050 Ti.

For Which Programmers And Developers Could The M1 Chip Be Worthwhile?
The M1 is not a workstation CPU. Anyone who compiles complex code is better off doing it on a real workstation. Compared to many other Ultrabooks, the M1 is a respectable solution enabling many programmers to work on the go.
The New Apple SoC Is Suitable For Web And App Developers
For example, if you work as a web or app developer, the M1 can fully exploit its advantages, offers a long battery life, and can score with good performance thanks to the adapted programs. However, if you depend on Rosetta 2, the M1 loses its appeal for developers because of its inability to run the code natively. However, Apple is working hard with the companies on improvements and optimizations, which may change in the future.
Windows Apps On The M1?
If you want to use Windows apps on the M1, you can use CrossOver. Another translation layer is used for this. This time then from Rosetta 2 on Windows. Although this creates more overhead and you have to accept performance losses, the performance should be sufficient for most programs and games like “Among Us” and “Team Fortress 2,” according to the developers. You should also be aware that CrossOver is not free and, depending on the license, causes one-off or annual costs.
Advantages Of The Chip And The Architecture
The most significant advantage of the chip is its very high energy efficiency. With the M1, Apple has created a competitive chip for ultrabooks that manages with a passive, fanless cooling solution and offers a long battery life. A single charge lasts for 8 to 12 hours. The performance is also impressive – in native mode – and Apple is already in talks with many developers to be able to offer improvements and optimizations here.
Disadvantages Of The Chip And The Architecture
However, the chip’s biggest advantage is its most significant disadvantage: The ARM architecture was not created for desktop CPUs, but the M1 is a hybrid that would theoretically need both. With Rosetta 2, Apple has a solution for this, but it only sometimes works satisfactorily and, in addition, significantly reduces the advantages in terms of performance. In addition, there is no possibility for virtualization so far, meaning that malware can be contracted more quickly at work.
Conclusion
If Apple manages to convince enough software manufacturers of the qualities of the architecture, the M1 could be a natural alternative to “normal” ultrabooks in the future. In the current state, however, you should think twice before buying and answer whether you can live with the disadvantages of the architecture.
