I was looking to confirm where to find which Intel Onboard Graphics processors have support for bounding box emulation, looking at https://software.intel.com/en-us/articles/software-occlusion-culling my poor understanding suggests that this may be part of AVX?
If anyone can point me in the right direction, I wasn't able to find a specs sheet on the site which lists all these things but I think bounding box is a graphics rendering technique where as it's emulation is handled by an unrelated hardware feature.
