Some new information appeared on the Xbox Scorpio, which will likely be named 'XBox 10 S'. Microsoft found a way to address more graphics memory, allowing not 8 GB but 9 GB of graphics memory.
Scorpio has 12GB GDDR5 memory and initially Microsoft stated it would use 4 GB out of the 12 GB, which was needed for system functionality. Through twitter Micosoft announced that this number has been reduced towards 3GB. Games that don’t use the full 9GB could use the extra RAM as a cache (making things load faster). Earlier on Microsoft claimed it would need the extra 4th GB to be able to run it's interface on 4k.
Other specifications of the console are an AMD X86 processor with eight-cores running at 2.73 GHz. Project Scorpio features a custom 16nm FinFET SoC with an embedded AMD Polaris GPU that has 40 Compute Units (x64 = 2560 shader processors) at 1172MHz. The unit would deliver 6TFLOPs of compute performance. It's expected that during E3 Microsoft will unleash more detail, the final name and equally as important, the price-tag.
