Realtime Shadows
Realtime Shadows work on most PC, console & mobile platforms. On Windows (Direct3D), the GPU also needs to support shadow mapping features; most discrete GPUs support that since 2003 and most integrated GPUs support that since 2007. Technically, on Direct3D 9 the GPU has to support D16/D24X8 or DF16/DF24 texture formats; and on OpenGL it has to support GL_ARB_depth_texture extension.
Mobile shadows (iOS/Android) require OpenGL ES 2.0 and GL_OES_depth_texture extension, or OpenGL ES 3.0. Most notably, the extension is not present on Tegra-based Android devices, so shadows do not work there.
Post-processing Effects
Post-processing effects require render-to-texture functionality, which is generally supported on anything made in this millenium.
Shaders
In Unity, you can write programmable or fixed function shaders. Programmable shaders are supported everywhere, and default to Shader Model 2.0 (desktop) and OpenGL ES 2.0 (mobile). It is possible to target higher shader models if you want more functionality. Fixed function is supported everywhere except consoles.
