Spartan rendering engine (also known as EdgeHTML) is the name of the layout engine for the Spartan browser, and is a fork of Trident.[2] The rendering engine was released as an experimental option in the Windows 10 Preview 9926 build.[3]
The rendering engine is the primary engine used in the Spartan Browser. It is also used in Internet Explorer 11, in a dual-engine arrangement with Trident (which is available for backward compatibility reasons) in Windows 10.[4]
A review of the engine in the latest Windows 10 build by AnandTech found substantial benchmark improvements over Trident; particularly Javascript engine performance, which is now up to par with that of Google Chrome.[5] Other benchmarks focusing on the performance of the WebGL API found EdgeHTML to perform much better than Google Chrome and Mozilla Firefox.[6]
