Archive
Everything published on TechX, newest first, and the complete index of every figure measured. 20 articles across 4 sections, all of it produced on one machine.
The four section pages are the better route if you know what you are looking for: each states what belongs in it and what does not, and lists its own articles with their headline figures. This page exists for the two things a section page cannot show. The first is the whole corpus at once, in publication order, which is the only way to see how the coverage has actually developed rather than how it is organised. The second is the measurement index below, which is the only place every number this site has produced appears together with its run count.
That index is worth more than it might look. A figure on this site is never published alone: it carries the label of what was measured, how many runs it came from, and the spread between those runs where they differed. Collecting them in one table makes it possible to see at a glance which claims rest on a single observation and which rest on repeated measurement, without opening twenty articles to find out. Where a run count is 1, the article describes the figure as an observation rather than a measurement, and that distinction is deliberate.
Every figure here came off the same MacBook Pro with an Apple M4 Pro and 24 GB unified memory, running macOS 26.3.1 (build 25D771280a). One machine is a real constraint and it is the reason this archive is small. It is also the reason the numbers in it can be compared with each other: when a figure changes between two articles, the change is in the software or the method, not in an unlisted difference between test units. The full method and its limitations are on the how we test page.
Published between 22 May 2026 and 3 August 2026. Articles are dated by when the testing was done, not by when the page was last touched; where a figure has been re-tested on a newer OS build, the article carries both stamps.

Every measurement
Each figure with the number of runs behind it. A run count of 1 marks a value that can only be observed once, such as a build number or a cycle count, and those are described as observations rather than measurements in the articles themselves.
