The AMD 700 chipset series (also called as AMD 7-Series Chipsets) is a set of chipsets designed by ATI for AMD Phenom processors to be sold under the AMD brand. Several members were launched in the end of 2007 and the first half of 2008, others launched throughout the rest of 2008.

The existence of the chipsets was proven in October 2006 through two hardware websites in Chile and Spain which posted the leaked slides of an ATI internal event, "ATI chipset update". In the slides, ATI has shown a series of RD700 series chipset logics codenamed RD790, RX790, RS780 and RS740 respectively. A SB700 southbridge was also mentioned in the event. The 790X (codename RD780) chipset was spotted in Computex 2007, exhibited by ASUS. The RS780D was first reported by HKEPC while the RX780H was first seen on ECS internal presentations.

After the acquisition of ATI Technologies, AMD started to participate in the development of the chipset series. And as a result, the first performance and enthusiast segment chipsets products under the AMD brand, the 790FX, 790X and 770 chipsets were launched on November 19, 2007 as part of the Spider codenamed desktop performance platform. The 780 chipset series, first launched in China on January 23, 2008, and released worldwide on March 5, 2008 during CeBIT 2008, mobile chipsets (M740G, M780G and M780T chipsets) were released on June 4, 2008 during Computex 2008 as part of the Puma mobile platform and the 790GX chipset was released on August 6, 2008, while some other members released at a later date in 2008. The 785G was announced on August 4, 2009.

Besides the use of SB600 southbridge for earlier releases of several members in late 2007, all of the above chipsets can also utilize newer southbridge designs, the SB700, SB710 and the SB750 southbridges. Future server chipsets will also utilize the server version (SB700S/SB750S) of the southbridges. Features provided by the southbridge are listed as follows:

The ATI CrossFire X technology supports multiple video cards to be connected to enhance the visual display and 3D rendering capabilities of the system, using AFR mode and/or scissor mode. Alternatively, systems with multiple video card CrossFire X setup will support multiple display monitors up to eight.
