What the patent situation is, I don’t know, but clever reverse engineering is another plentiful Silicon Valley skill. The legal battles might be protracted and vicious, but the bottom line is that Apple’s M1 magic might not be secret or proprietary for nearly as long as the company would’ve liked. If Apple isn’t just a tiny bit upset over this development, dye my hair red and call me Harpo. The real stunner is Qualcomm, a huge supplier of ARM-based chips, entering into an agreement to purchase fledgling Nuvia. There’s a lawsuit in progress over this.īut wait, there’s more. He strayed from Apple to form a company called Nuvia that works on-yup, you guessed it-CPU designs. Said big cat is one Gerard Williams III, who until quite recently was the chief of all of Apple’s ARM CPU efforts. The Days of Our Lives, Silicon Valley style Even Microsoft has supported ARM for quite a while, first with Windows RT (8.1/32-bit ARM), and now with Windows 10 for ARM.

It’s in nearly every mobile phone, most portable devices, TVs, and more, though under licenses that allow the vendors to call their ARM implementation anything they want.

This is partly due to the Rosetta 2 install time translation (or requested), but Apple doused the M1 with some of what I call “special sauce”-sly tricks that include support for x86 memory ordering, one of the main differences between Intel and ARM architectures.ĪRM is hardly new. It’s faster than my 2015 iMac with an Intel Core i7. Thanks to unified direct-access memory, integrated GPU cores, and cores dedicated to common tasks (such as H.265 video encoding), it’s fast as all get out.īut its most surprising trick is running x86/圆4 Mac apps at more than acceptable (if not quite native) speeds. Just in case this whole deal is new to you: Apple’s M1 is a system on a chip (SoC) based on the Advanced RISC Architecture/Reduced Instruction Set Computing/Instruction Set Architecture (ARM RISC ISA).
