Note that ‘power’ in this context refers to electrical power, not computational power. The single-letter suffix on each model of processor denotes whether it can be overclocked (K), or is low-power (S) or ultra-low power (T). Furthermore, up to three separate displays can now be driven simultaneously, reducing the need for a discrete graphics card where triple-head monitors are required. With this new generation of CPUs the graphics are now known as HD 4600 and with the change of name comes about a significant improvement in performance, especially for 3D games and applications. Perhaps the biggest improvement is in the area of embedded graphics.
