AMD 700 chipset series

AMD 7-Series chipsets Logo

The AMD -700 - or - 7 series is a family of AMD chipset for AMD K8, K9 and K10 processors. The first models were presented on 19 November 2007 with the presentation of the "Spider" platform. The 7 series is AMD's first complete series of chipsets, AMD had previously presented only partial or rarely complete chipsets in the presentation of new generations of processors.


The AMD 7-Series is a first result of the acquisition of ATI Technologies. The chipsets were developed for this socket AM2 processors and the K10 generation whose first desktop models was also presented under the label of AMD Phenom November 19, 2007. However, they are backwards compatible with AM2 well as the older processors, the AMD K8 and K9 - generation base. Presented were the first models 790FX, 790X and 770

In the first quarter of 2008, new versions of the AMD 7-Series were introduced. These include the models 780G, 740G and 780V. In August 2008, then, the new top model 790GX followed with integrated graphics core ( IGP).

In August 2009, the 785G was introduced as the successor of 780G. Also new is a feature called Powerplay, so the 785G as even the 790GX lowers the clock of the graphics unit at light load to save power. Other new features include UVD 2.0 (Picture-in -Picture function) and DirectX 10.1.


The 7-series chipsets are the first to be fully Socket AM2 compatible. The main innovations are included in support of HyperTransport version 3.0, to create the possibility to different cores have different voltages and clock speeds. Also new is support for the PCI Express interface further developed in version 2.0.

As Southbridge first only the older SB600 was used as the advanced version of SB700 was not yet completed. This applies to the 790FX, 790X and 770 models For this reason, some required points for the high-end AMD 790FX chipset, such as six SATA II ports, handled by additional chips.

The next generation (models 780G, 740G and 780V ) can rely on the revised SB700 it. This brings among other things, six SATA II and twelve USB ports with it, but it reduces the use of Windows Vista with Service Pack 1 or later USB performance somewhat.

With the introduction of the 790GX model and the associated SB750 an error in the clock of the South Bridge has been fixed; the USB performance problem under Vista but there continue. In addition, an overclocking technology enriched with the name Advanced Clock Calibration (ACC ) the possibilities of processor overclockers. With this function it is with a suitable motherboard BIOS also possible to unlock the disabled cores on some processors, the Phenom II X2 and Phenom II X3 series.

The program "AMD Overdrive" supports the user in that it can perform system tests and change system settings.


AMD advertises a very low power consumption of the chip sets of 7 series against the competition of the Intel platform, among other things, due to the ( for chipsets new ) 65 -nm and 55 - nm technology. However, the values ​​are not directly comparable, since Intel Core 2 processors, the memory controller is still in the Northbridge and not in the CPU, which shifts a portion of the power from the microprocessor to the Northbridge.

Model Overview

All chipsets are named after the northbridge used.
