Ken Shirriff: ARM1 processor compared to Apple's M1 processor
- maxharris 6y agohttps://sneak.berlin/20201112/your-computer-isnt-yours/ https://sneak.berlin/20201112/your-computer-isnt-yours/ Edit: I posted this because that shiny new ARM ISA-based Mac comes with a massive loss of privacy. It bothers me that this is happening, and I genuinely just want people to know what they are doing when they buy into one of these things. This situation makes me doubly sad, because the architecture is really neat, and the machine embodies a great number of remarkable technical achievements.
- hn_throwaway_99 6y ago> The ARM processor started with the Acorn RISC Machine project in 1983. Apple got involved in the late 1980s, using the low-power ARM 610 processor in the ill-fated Newton handheld. In 1990, Acorn, Apple, and VLSI Technology formed Advanced RISC Machines, with Apple owning 43%. That was news to me, as I didn't realize Apple had such a foundational role in the early stages of ARM.

- jecel 6y agoA few comments pointed out that the 1992 ARM 250, as the first SOC, would be a better comparison for the M1. https://en.wikichip.org/wiki/arm_holdings/microarchitectures/arm250 https://en.wikichip.org/wiki/arm_holdings/microarchitectures... 1000 nm CMOS process, two metal layers, 98,019 transistors in 58 mm²
