At the GDC last week Microsoft's Eric Walston, from the Xbox Advanced Technology Group, provided a more detailed analysis of Windows 10 Game Mode than we had previously seen / heard. Walston explained that currently a game is just another process in Windows but Game Mode will go further: to exclusively devote certain CPU resources to the game.
CPU - Game Mode implications
An example of an octa-core CPU in a PC was given in a report by Ars Technica. With Game Mode active six of the cores could be dedicated to gaming while the other two take care of essential system tasks. Clearing the gaming-focussed cores of other processes reduces thread contention and improves performance.
It will be interesting to see if the above changes really make it worthwhile to have a modern octa or hexa-core CPU rather than a high clockspeed dual or quad-core for gaming.
