AMD's Neal Robison, senior director of content and application support, told X-bit Labs that APUs will definitely challenge standalone CPUs and that processors without graphics cores may cease to ecist in the future. Additionally, he also revealed that APUs will only confront low-cost systems, they will not go head-to-head with discrete graphics cards.

But while APUs will confront low-cost systems, they will not challenge and will not become part of advanced personal computers with discrete graphics cards.

"I do not think that APUs will challenge discrete GPUs on anything, but on the lowest-end systems. When you look at adding a discrete GPU that enhances performance of the graphics side, it makes a huge amount of sense as it scales [performance] on a wide amount of applications because of the rich visual experience that everybody expects now when they are actually using their computing device," added Mr. Robison.

A good example of APU integration is this.
