Rust asks for at least a Ryzen 5 1400 or Core i5-6600, a Radeon RX 470, GeForce GTX 1060 or Arc A580 and 12 GB of memory. Choose your parts to check your PC against each level.
Windows shows it under Settings, System, About, as “Installed RAM”.

Each card links to the power supply it needs. A laptop’s graphics run well below the desktop card of the same name, so a laptop can fall short where the desktop card meets a level.
Each requirement names parts, usually one from each maker, and any of them is enough: your part meets it when it is at least as fast as the slowest part named. Speed is the same figure the bottleneck calculator uses, for games at high settings. Parts the requirements name that are not in our list are placed from published benchmark results, against their nearest relative in the list: Notebookcheck’s Cinebench R15 results for processors and its 3DMark results for graphics cards. A few with no usable results are counted as a part in our list of the same design that they are no faster than, which errs towards saying no. Graphics memory is checked when the publisher asks for an amount; built-in graphics use the PC’s own memory instead.
Requirements describe the PC a publisher tested on. How well a game runs on yours also depends on what its parts are really doing: memory below its rated speed, a graphics card held back by heat, a processor that falls behind in busy scenes, a monitor held at 60 Hz. Bottleneck’s game check records a game while you play and says what set the pace, frame by frame: the processor, the graphics card, or a frame cap. It counts the stutters too.
The free version gives each check’s verdict, with no time limit and no account. Pro, $9 once, explains the cause and the fix. Compare the versions
