GPU: Graphics card with DX10 (shader model 4.0) capabilities.

The rest mostly depends on the complexity of your projects.

Additional platform development requirements:
  • iOS: Mac computer running minimum macOS 10.13+ and Xcode 9.0 or higher.

  • Android: Android SDK and Java Development Kit (JDK); IL2CPP scripting backend requires Android NDK.

  • Universal Windows Platform: Windows 10 (64-bit), Visual Studio 2015 with C++ Tools component or later and Windows 10 SDK

For running Unity games

Generally content developed with Unity can run pretty much everywhere. How well it runs is dependent on the complexity of your project. More detailed requirements:

  • Desktop:

    • OS: Windows 7 SP1+, macOS 10.13+, Ubuntu 18.04+
    • Graphics card with DX10 (shader model 4.0) capabilities.
    • CPU: SSE2 instruction set support.
  • iOS player requires iOS 11.0 or higher.

  • Android: OS 4.4 or later; ARMv7 CPU with NEON support; OpenGL ES 2.0 or later.

  • WebGL: Any recent desktop version of Firefox, Chrome, Edge or Safari.

  • Universal Windows Platform: Windows 10 and a graphics card with DX10 (shader model 4.0) capabilities
