ShaderToyMark is an OpenGL benchmark, developed with GeeXLab, and focused on pixel shaders only. ShaderToyMark? is a WebGL tool for testing GLSL shaders. Shadertoy utilises several of these shaders running at the same time in the same 3D window.
The contributors of Shader Toy are all famous demomakers and their shaders are real gems. It’s just amazing to see what can clever people do with some sin/cos and other math tricks. ShaderToyMark can be seen as a modest tribute to their fantastic and sometime unreal work.
Unfortunately Shadertoy doesn't work properly in Crossfire or Sli, meaning we need to use single card statistics. The findings are close, the XFX HD6850 is only 9 points behind the reference clocked GTX460.
