CPU processing is like a free way with 8 lanes. If all the cars (calculations) are trying to use one lane you will see a traffic jam and all cars will drastically slow down. When the program is coded to use 6 lanes, it will distribute the cars across all lanes and have a much higher bandwidth.

Previously 2 of 8 lanes were car pool only (OS), and have now 1 of those carpool lanes has been opened up to other traffic. Previously, carpoolers had 2 lanes to themselves (limited traffic) and didn't have issues with slow downs. Now that 1 of those lanes has been opened up to the general public - the general public will have less congestion -- but the car poolers have only 1 lane.

But the car poolers probably became more efficient and started to share cars so 1 lane is sufficient 

It's fun to speculate, could be many things.

OS might be more efficient now, or maybe the extra cpu was held back in case tv, dvr, snap, internet browser etc, became very important. Same with all the memory resevered for the OS. Since the strongest selling point is games, the reserved resources can now be made available.

The less the OS does in the background the better anyway. With only 1 slow hdd to share, anything the OS does has an impact on the game you're running.

Back to the carpool lanes, 2 lanes were available when the highway opened. Not enough people were interested in car pooling, thus the extra lane was better used for the general public. Same with XBox One where reservations for Kinect proved to be pointless.

It would be interesting to know what kind of plans they might have had. For what the OS does now you don't need 2 cores. Doesn't the ps4 have an extra low power chip already for background downloads? http://vr-zone.com/articles/second-ps4-processor-extra-gddr3-ram-revealed/64081.html So what does the OS do while a game is running.
