Similar to previous chips, Scorpio has 2 command processors (i.e., microcontrollers) that handle graphic and compute tasks however they are said to handle more parallel compute tasks than previous chip in order to increase performance. The number of ACEs (Asynchronous Compute Engine) on Scorpio has doubled to 4 in order to increase the [[parallelism]] possible. It's worth pointing out that since the Scorpio Engine is based on {{amd|Arctic Islands|l=arch}}, there are also two additional schedulers. | Similar to previous chips, Scorpio has 2 command processors (i.e., microcontrollers) that handle graphic and compute tasks however they are said to handle more parallel compute tasks than previous chip in order to increase performance.

The render back-end has also been enhanced. The render back-end consist of eight ''Render Boxes'' (RB) color/depth engines, each with 256 KiB graphics L2 cache for a total of 2 MiB. Each pair of Render Boxes is wired to one ''Memory Controller Cluster'' (MCC). Each MMC consists of two dedicated memory controllers and two more that are shared between two pairs of MCCs. In total there are four clusters with each having two dedicated controllers and two more pair (4 controllers) of channels shared between a pair of MCCs for a total of 12 channels. | The render back-end has also been enhanced.
