The graphics on the upcoming Xbox One console are about to get even better. Ars Technica notes that Xbox One chief product officer Marc Whitten revealed this week that Microsoft has bumped up the speed on Xbox One developer kits to 853MHz, a boost from the 800MHz that developer kits’ GPUs previously ran at. Ars says that while a 7% increase in GPU speed “isn’t massive in the scheme of things,” it’s still a good sign that Microsoft “feels comfortable boosting clock speed like this” because it may mean that “things are going well with the console’s semi-custom AMD processor.” Microsoft plans to release the Xbox One sometime in November, just in time for the holidays.
