It’s an interesting question regardless. Either there are no additional savings to be found in the console, therefore already efficient as possible (unlikely imo). Or they are bound to xcloud and cannot revise the chips (possible?) as they are linked to specific blade specifications.The quantity of XSX at retail isn't equivalent to how many SOC's they produce.
Remember they are still building out xcloud and the blades are built on XSX chips.
Maybe they simply don't believe there's a benefit to respins and minor redisigns and updates, especially if it won't allow them to get many more XSX out there.
Any other ideas welcome. I am curious to know the answer.
If it is the prior the only revision would be a slim model I suppose, and that would require a node change.
