3DNow!

Another additional set of instructions on some CPUs that work similarly to MMX, but are focused on increasing the performance of 3D applications. Read the MMX note and study how the usage of MMX saturation vastly simplifies (and therefore speeds up) image manipulation.

The 3DNow instruction set has the same effect between the 3D application and the FPU, i.e. it simplifies the process the 3D application has to go through to calculate something with through the FPU, say from a dozen FPU calculations per pixel down to two or three instructions. This vastly improves the speed of the applications!
