I am looking to get a new comuter, and i will have to do 3D modeling with it, so what i'm wondering is which company has a better system in place for blender, AMD or NVIDIA?
Looking at the system requirements Blender uses OpenGL extensively, and AMD has better OpenGL optimization. Glossing over at an early review at AnAndTech (http://www.anandtech.com/show/6332/amd-trinity-a10-5800k-a8-5600k-review-part-1/6), it shows that AMD APU's have greater OpenGL implementation, I can only assume that this optimization is at the architecural level and is implemented across all their Radeon products.
Nvidia at least until the rendering engine in blender gets good support for opencl going.
