Frame rigidity and spindle power, then the bed you can clamp to
A desktop CNC router cuts a file out of a solid sheet with a spinning end mill, removing material rather than adding it, and its specifications are mostly about stiffness. Working area is a declared travel on three axes, and the height axis limits how thick a block can be. The frame and rails — aluminum extrusion, steel, linear rails or wheels — decide how much the tool deflects in a cut, and that deflection decides whether hardwood and aluminum are possible or only foam and soft wood. Spindle power in watts and its speed range are published, and a trim-router mount offered as an option is a step up the maker names separately. The collet size sets which end mills fit. Controller type and the software it accepts decide the workflow, and an offline controller lets the machine run without a computer beside it. Limit switches and an emergency stop are safety provisions a listing should state. Then dust: a router makes chips and fine dust, and an enclosure or extraction port the maker lists is part of using one indoors. We compare working area, frame and rails, spindle power and speed, collet size, controller and software, limit switches and published material claims.

An all-metal frame and ER11 collet from a well-reviewed line.
The structure and materials of the body, published by the manufacturer. They explain the rigidity available under cutting load.
The tool shank diameter the spindle accepts. It is published and decides which cutters can be used.
It interprets G-code and drives the motors. The published controller says which firmware it runs.
The published software indicates what the manufacturer provides for. Toolpath generation is often a separate tool.
The spindle rotation range, published in revolutions per minute. It is read with power, not alone.
That depends on the published spindle power, frame and rails. This site draws up no list of materials to machine.
The type of linear guidance used on each axis. They are published and explain part of the precision.
Cutting and the spindle generate noise. This site publishes manufacturer specifications and performs no measurement.
Stiffness decides what a router can cut. Read the rails and the spindle before the list of materials.
There is no table here, and the reason is in the listings. The figure published most often across these 9 products is weight, given by 7 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
Specifications: manufacturer sheets for maker machines and tools and the matching Amazon product pages. Prices and availability: Keepa.

A price quoted in the text of a MakerVerdict page dates from the day that page was written; the live figure beside each product is fetched while you read and replaces it.
