I can't find any benchmarks off the top of my head but if you need GPU performance for DX or OpenGL, Intel integrated graphics is definitely not the place to look. They are developing in support and performance but still lag behind AMD and Nvidia in both while also sacrificing quality for performance
Where to look?
If you are willing to sacrifice CPU performance, look at AMD A-series processors.
If you are not willing to sacrifice CPU performance, add a dedicated AMD Radeon or Nvidia video card to your system for under $80.
If you are looking at a laptop, look at the AMD A-series mobile processors
Or purchase a laptop with dedicated AMD or Nvidia graphics.
