That's kind of a straw man argument, don't you think? So because there is an inability to counter the evidence with what he rightfully points out is stated in that article, and now apparently supported by an official hot chips presentation from Microsoft on the Xbox One Silicon, you've resorted to piling on him to name or describe a technique that very few, or none, discussing this matter currently are capable of understanding just to shift the discussion away from the points he has made.
And I'm simply asking in response to that how can any of us possibly know for certain that Microsoft didn't build these capabilities into the chip in the first place? We have never known or understood with any sort of low level depth how Microsoft built or designed the various parts of the Xbox One, least of which the ESRAM. If their hot chips presentation is to be believed, and the information DF presented in that article about the X1's ESRAM really has been communicated to game developers (lying to developers you need to make games on your system is never good of course), then doesn't the prospects that Microsoft might actually be telling us the truth about the ESRAM occur in the slightest? It can't always be that they are lying to everybody. The main point is what do they gain at this point? The ESRAM bandwidth does nothing to change the well known advantages that the PS4 is already known to possess.
