To put this into perspective, x86 arch (Complex Instruction Set Computing) has around 981 instructions compared to around 50 for arm64. Fundamentally, the arm64 CPU architecture uses a smaller CPU instruction set, where principally each instruction performs one function. RISC in turn stands for Reduced Instruction Set Computer. There’s no doubt that the folks at Apple are great at marketing, but what exactly are they selling? Why is there so much hype around this being the next must-have machine for recreational and professional users alike?ĪRM stands for Advanced RISC Machine. So what does that mean for the developer experience at Picnic? Before we can build (CI), test (QA), deploy (CD), and maintain our software in production, the first step in the DevOps cycle is of course to design and build software on our very own machines. The transition from intel x86 to Apple M1 arm64 directs how we build software on this platform. The JetBrains and StackOverflow developer surveys show that Windows still remains the leader in terms of development hardware and whilst the share has remained fairly stable over the last 4 years, with 44–49% for MacOS between 20 according to JetBrains, a large number of software developers choose to use Apple hardware¹. The Picnic iOS team even organises viewing parties to watch along every year!Īpple’s transition to their arm64-based M1 System-on-Chip (SoC) in all Mac products sets the direction for not only what software runs on, but what it’s built on. For tech giants and scale-ups alike, ambitious strategic tech moves bring with them a buzz of excitement. This marked the 3rd time in Apple’s history that the tech giant had transitioned to using a new CPU architecture. On June 22, 2020, CEO Tim Cook announced Apple’s two-year transition plan to their own silicon in his WWDC keynote speech.
