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

development

The AMD 7 series is a first result of the acquisition of ATI Technologies . The chipsets were developed for Socket AM2 + and processors of the K10 generation, the first desktop models of which were also presented on November 19, 2007 under the AMD Phenom label . However, they are also downward compatible with the older processors of the AMD K8 and K9 generation for Socket AM2 . Initially the models 790FX, 790X and 770 were presented.

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

In August 2009, the 785G was presented as the successor to the 780G. A new feature is called Powerplay, with which the 785G, like the 790GX, lowers the graphics unit's clock rate in order to save power. Other innovations are UVD 2.0 (picture-in-picture function) and DirectX 10.1.

Functions

The 7 series chipsets are the first to be fully compatible with Socket AM2 +. The main innovations included are support for HyperTransport version 3.0, the ability to apply different voltages and clock rates to different cores. Another new feature is the support for the further developed PCI Express interface in version 2.0.

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

The next generation (models 780G, 780V and 740G), however, can rely on the revised SB700. Among other things, this brings six SATA-II and twelve USB ports with it, but the USB performance is slightly reduced when using Windows Vista with Service Pack 1 or higher.

With the introduction of the 790GX model and the associated SB750, a bug in the Southbridge clock was fixed; the USB performance problem under Vista still exists. In addition, an overclocking technique called Advanced Clock Calibration (ACC) enriches the possibilities of processor overclockers . Via this function, it is with a suitable motherboard - BIOS also possible in some processors unlock the Phenom II X2 and Phenom II X3 series the disabled cores.

The " AMD Overdrive " program supports the user by performing system tests and changing system settings.

Power consumption

AMD advertises the very low power consumption of the 7 series chipsets compared to the competition on the Intel platform, partly due to the 65 nm and 55 nm technology (new for chipsets). The values ​​are not directly comparable, however, since the memory controller of Intel Core 2 processors is still in the north bridge and not in the CPU, which shifts part of the power consumption from the microprocessor to the north bridge.

Model overview

All chipsets are named after the Northbridge used.
