A terminal-based electronics simulator called 'circuit' allows users to build and test circuits with batteries, resistors, capacitors, LEDs, switches, and transistors on a grid. The tool includes progressive challenges from lighting an LED to building a stopwatch, with real-time voltage and current visualization.
Apple Silicon chips (M2 through M5) achieved approximately 50% single-core performance improvement over three years, driven primarily by increased CPU frequency (3.5 to 4.6 GHz), higher instructions-per-cycle decode width, additional efficiency cores, and significantly improved memory bandwidth (154 GB/s on M5 versus 100 GB/s on M2). The newer M6 chip adds further performance gains through additional cores and bandwidth increases.
