AMD are recognized as the "gamers choice" for CPU due to the features of their CPU’s matching well to the demands of the gaming market. AMD produce CPU’s that run cooler and faster and more reliably than any of their competitors.AMD have a very strong embedded group which guarantees long supply times for its parts through embedded roadmaps released to its partners. This enables us to guarantee to supply you our platforms for minimum of 7 years from the release date of that platform.



Microsoft has a strong and ever expanding market presence within the gaming industry with many of the machines in operation today running Windows 7 Embedded.

As a Licensed Microsoft partner, Quixant is able to supply the Windows 7, Windows 8 and Windows 10 licences as part of its platform.




We fully support the Linux community with a full set of drivers and API’s for our product. So if you choose to develop your games with a Linux OS feel confident that Quixant is here to support you.
