AmpereOne: Cores are the new MHz

Raspberry Pi 500 uses QMK Firmware for built-in keyboard I mentioned in my Pi 500 review Raspberry Pi is dogfooding their own microcontroller in the new Pi 500. An RP2040 sits next to the keyboard ribbon cable connector, and interfaces it through a USB port directly into the RP1 chip: In good news for keyboarding enthusiasts, the...

The Pi 500 is much faster, but lacks M.2 Raspberry Pi this morning launched the Pi 500 and a new 15.6" Pi Monitor, for $90 and $100, respectively. They're also selling a Pi 500 Kit, complete with a Power Supply, Mouse, and micro HDMI to HDMI cable, for $120. This is the first time Raspberry Pi is selling a complete package, where...

Raspberry Pi boosts Pi 5 performance with SDRAM tuning tl;dr Raspberry Pi engineers tweaked SDRAM timings and other memory settings on the Pi, resulting in a 10-20% speed boost at the default 2.4 GHz clock. I of course had to test overclocking, which got me a 32% speedup at 3.2 GHz! Changes may roll out in a firmware update for all Pi...

Home Assistant Yellow - instant 2x IoT speedup with CM5 In a win for modular, private, local IoT, I just upgraded my Home Assistant Yellow from a Raspberry Pi Compute Module 4 to a Compute Module 5 this morning, and got an instant 2x speed boost. I first posted about the Yellow in 2022, and walked through my smart-but-private HA...

Raspberry Pi CM5 is 2-3x faster, drop-in upgrade (mostly) The Raspberry Pi Compute Module 5 is smaller than a credit card, and I already have it gaming in 4K with an eGPU, running a Kubernetes cluster, and I even upgraded my NEC Commercial display from a CM4 to CM5, just swapping the Compute Modules! The Compute Module 4 was hard to...
