TESTED HARDWARE

Tested hardware.

The machines ibara is developed and tested on. Both are five-year-old, low-power ACEPC mini PCs with the same Celeron J3455 processor, the kind of spare computer ibara is built for.

Machines#

Most runs on Test results, and all but one figure on Benchmarks, come from these two: tasks in signed-in browsers, saving files in a desktop app, Take Control and Hand Back, sending files between them, ibara’s memory (with tater1 limited to 2 GB, and again on tater0’s full memory), four agents connecting themselves from one prompt, and 73 benchmark runs by real agents.

ACEPC AK2 mini PC · dedicated agent computer

CPU: Intel Celeron J3455 · 4 cores · 1.5–2.3 GHz · 10 W TDP
MEMORY: 8 GB
STORAGE: 128 GB SATA SSD, encrypted
SYSTEM: Omarchy 4.0.4 · Hyprland 0.56.2

MEMORY: 4 GB
STORAGE: 64 GB eMMC
SYSTEM: Omarchy 4.0.4 · Hyprland 0.56.2
AGE: 5+ years
POWER: 10 W processor rating; mini PCs like this typically draw 6–15 W at the wall not measured
RUNNING COST: About $13 a year at 10 W around the clock and $0.15/kWh (87.6 kWh); $8–20 across 6–15 W estimate

RATINGS, NOT MEASUREMENTS

Power is the processor’s 10 W rating and the typical draw of mini PCs like these, not a reading from these machines. Running cost is worked out from it the same way as the cost calculator: watts × 24 hours × 365 ÷ 1,000, times $0.15 per kWh.

How we measure#

Specs come from the machines themselves. Memory is measured on the machine with ibara running; the figures are under resource use. Power isn’t measured: it’s the processor’s rating and typical draw, and each figure on this page is labelled.

Both machines are also on Registered machines, where anyone can add a computer.
