− | Scorpio Engine feature 40 | + | Scorpio Engine feature 40 Compute Units (CUs) based on {{amd|Arctic Islands|l=arch}} (Similar to Polaris, Radeon RX 4xx). This is triple the amount over the original Xbox One SoC. The Compute Units operate at 1,172 MHz, each with 64 32-bit [[floating point]] [[multiply-accumulate]] units. At 1.172 GHz with 128 FLOP/cycle this chip can deliver 6.00064 [[TFLOPS]] raw peak performance - over four times previous chips (which were 1.3 and 1.4 TFLOPS). The performance of texture processing has also been increase to 187.5 G bilinear [[texels]]/second. Additionally, in each of the four [[shader]] arrays, there is one geometry engine for the purpose of doing fixed geometry processing, this is twice previous chip which is capable of 4.688 Giga primitives/second. |
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.
