System requirements

QuPath is designed to run on Windows, Mac OS X and Linux.

Minimum specification

QuPath won't run properly with all features unless you have at least the following:

64-bit processor & operating system
4 GB RAM (for browsing images, limited analysis)
500 MB hard disk space
For Mac, at least OS X 10.7.4

Recommended specification

Ideally, for better performance you would have the following:

Multi-core processor (e.g. Intel i7)
16 GB RAM
Discrete graphics card
Solid state hard disk
Lots of hard disk space to store images and data - may require up to 1 GB to store data related to a single slide

Extra notes

It's may be difficult (or prohibitively expensive) to meet both of the last two criteria of the recommended specification; a good compromise is a solid state hard drive for what you're currently working on, and a larger external hard drive or network storage for archiving results. If you're working with whole slide images stored on your local computer, the faster performance of solid state hard drive is a major help because of the need to constantly read new parts of the image from disk.

In general, QuPath tries to make the most of whatever hardware is available. So if you've more processors, QuPath can use them and the analysis will be faster... as long as you've enough RAM to support them. See Setting memory limits for more information.

For what it's worth, QuPath has been developed and regularly used on the following systems:
