Cardsreaching the fleet…

Every donated card sits an entrance exam before it may contribute: one supertile, at a region and a pass count the work pins, identical on every machine. The time it takes is the only number in this whole protocol that two strangers’ computers produce under exactly the same conditions — so it is what this table ranks on, as passes per second rather than seconds, so the figure carries across works of different sizes.

What the commons runs on

Cards running below their own clock

A card can be healthy and still render at a fraction of its speed: a GeForce GTX 1080 on this bench sat at 708 of 1911 MHz core and 810 of 5005 MHz memory, drawing 21 W of a 180 W board, while its own driver reported 100% utilisation throughout. It rendered at one seventh of its speed and nothing anywhere reported a fault. The donor kit now says so on the spot, and this counts how often it happens in the wild.

Is it rendering as it should

Every card computes the same seven functions the deterministic camera is built from. They are not the driver’s own: the camera carries its own sin, cos, atan, exp2, log2, sqrt and division, so that the answer cannot depend on whose silicon ran it.

How to file a row

The kit asks once, shows the row in full first, and sends nothing if you say nothing. A row describes the card — renderer, driver, OS, core count, clock state, exam time. Never a serial, a host name, a user name or an address, and the fleet refuses any row that carries one.
Groups of a single report are withheld from this page, because on a rare card an average of one is that machine.

Machines with no usable card

A software rasteriser is the CPU pretending to be a GPU. It opens, it answers every query, and it runs the work at roughly a two-hundredth of real hardware — so it is kept out of the table above rather than ranked last in it. These rows are here because “this machine had no usable card and fell back to software” is a true and useful thing for the table to know.
