Earlier this year, AMD released the 780G chipset. It featured integrated ATI 3200 graphics, which were the fastest integrated graphics found on a motherboard, and also had the capabilities of Hybrid Graphics. The 3200 also featured full Blu-ray decode acceleration allowing for 1080p playback with minimum CPU usage.
This chipset was so successful that AMD decided to design a new chipset based on it, giving it a higher clock speed, sideport memory, and upgrade to ATI 3300 integrated graphics. Along with the new NB, AMD has also built a new Southbridge, known as the SB750, which not only adds RAID5, but has added a new feature called Advanced Clock Calibration (ACC), that AMD claims will allow much higher overclocking of the Phenom CPU.
