Windows 7: Better Graphics Acceleration from Win7 to Win8?

Hi All

I just read an interesting article on the new Windows 8 Windows 8 graphics: Microsoft has hardware accelerated everything | ITProPortal.com. It says that Windows8 will be using better graphics acceleration to perform the decoding and rendering of images, shapes and text amongst others much faster than windows 7.

Now what exactly does that mean?



I know that the GPU is one of the hardware devices that supports hardware acceleration to take of load from the CPU, what other devices are used for graphic acceleration?

Thank You
