The main unit of the Xbox 360 itself has slight double concavity in matte white or black. The official color of the white model is Arctic Chill. It features a port on the top when vertical (left side when horizontal) to which a custom-housed hard drive unit can be attached in sizes of either 20, 60 (August 2008 onward) or 120 GB. Inside, the Xbox 360 uses the triple-core IBM designed Xenon as its CPU, with each core capable of simultaneously processing two threads, and can therefore operate on up to six threads at once.[55] Graphics processing is handled by the ATI Xenos, which has 10 MB of eDRAM. Its main memory pool is 512 MB in size.
