Vista Aero: What a CPU Hog!
Friday, March 23rd, 2007
Microsoft’s new Aero Glass GUI - one of the cornerstones of the company’s Windows Vista marketing message - is a joy to behold. Aero’s sleek, semi-transparent facades serve to enhance the user experience by providng a stronger sense of "depth" and cohesion. Combined with Vista’s enhanced UI metaphors (love those "breadcrumbs" in explorer), Aero is a major improvement over the XP GUI.
It’s also a CPU hog. Despite Microsoft’s claims about leveraging 3D accelerator technology to offload the GUI workload, Aero still chews-up more CPU cycles (an average of 22%) with desktop composition enabled (i.e. 3D accelerated mode) than with it disabled (i.e. non-accelerated "legacy" mode). In other words, turn on the "bling" and you toss nearly a quarter of your CPU bandwidth out the window.
