More Intel "GPU" Larrabee Architecture Disclosed

Well, it is important to keep in mind that this is first and foremost NOT a GPU. It's a CPU. A many-core CPU that is optimized for data-parallel processing. What's the difference? Well, there is very little fixed function hardware, and the hardware is targeted to run general purpose code as easily as possible. The bottom lines is that Intel can make this very wide many-core CPU look like a GPU by implementing software libraries to handle DirectX and OpenGL.

It's not quite emulating a GPU as it is directly implementing functionality on a data-parallel CPU that would normally be done on dedicated hardware. And developers will not be limited to just DirectX and OpenGL: this hardware can take pure software renderers and run them as if the hardware was designed specifically for that code.
