Comparison of AMD chipsets
In addition to processors, AMD offers especially chipsets for these processors. Originally, AMD did not see as a provider of chipsets, but at certain times repeatedly offered its own or purchased chipsets to facilitate motherboard manufacturers to transition to a new generation of processors and gaps in the provision of chipset manufacturers like NVIDIA, VIA, SiS and ULi to bridge. Only with the takeover of ATI Technologies integrated AMD chipsets these fully into its own product range.

History
K6
It started with the AMD -640, which was suitable for Socket 7 CPUs and should support the sale of the AMD K6. But this was just a chipset VIA Apollo umgelabelter VP2/97 and consequently has also its features. The offered as Southbridge AMD -645 was a umgelabelte VT82C586B.
Actually, should the AMD -640 still follow a chipset with 100 MHz FSB and AGP to support the concept of the Super Socket 7 for the AMD K6- 2 (with the chipset it probably would have traded around the VIA Apollo MVP3 ), but this chipset was never put on the market.
Athlon
With the onset of K7 - generation (AMD Athlon ) brought AMD then AMD 750 (codenamed Iron Gate ) on the market, which consisted AMD 751 Northbridge and the AMD -756 Southbridge from the. However, it was very often the VIA 82C686A used as Southbridge, because it was better equipped.
The AMD -750 was very important, since no additional matching chipset stood for the derived from the Alpha EV6 processor bus protocol of the Athlons are available. VIA Technologies had the KX133 not ready and the others should be waiting on first.
With the change to DDR SDRAM and the introduction of the AMD Athlon MP AMD brought then the AMD 760 series on the market. This was the one from the AMD -760 (AMD -761 Northbridge and AMD 766 South Bridge ) for the AMD Athlon and AMD Duron and on the other from the SMP -capable chipsets AMD -760 MP (AMD -762 Northbridge and AMD -766 Southbridge ) and AMD -760 MPX (AMD -762 Northbridge and AMD 768 South Bridge ) for the AMD Athlon MP. However, turn the VIA 82C686B was used very often instead of AMD766 Southbridge.
Athlon 64
Even with the launch of the AMD Athlon 64 or AMD Opteron, AMD had ready again corresponding with the AMD -8000 series chipsets, which should facilitate the recent change of platform. However, the chipset manufacturer this time were much faster and so the AMD -8000 series was mainly installed on server and workstation motherboards.
The AMD -8000 series AMD put completely on HyperTransport as chipset connection and can therefore no longer really talk about North -or Southbridge, as it is for the individual chip elements merely HyperTransport bridge chips (tunnel ), which could be combined depending on requirements. The following Chipset elements are present: AMD - 8151 ( HyperTransport AGP 3.0 Tunnel ), AMD - 8132 ( HyperTransport PCI - X 2.0 tunnel ), AMD - 8131 ( HyperTransport PCI - X 1.0 tunnel ) and AMD -8111 ( HyperTransport I / O Hub ). AMD - 8151, AMD - 8132 and AMD - 8131 are most likely comparable to classical Northbridge, while AMD -8111 largely corresponds to a classical Southbridge.
Then it was once quiet around chipsets from AMD. But thanks to the takeover of ATI Technologies, AMD got again a complete product program for chipsets, including IGPs, in the hand. They are now an integral part of AMD offer and have been fully integrated into the company's product range. While products for its own platform, were partly renamed, the products for Intel platforms continue to be marketed under the brand name ATI. New and further developments but there will be only for its own platform.
The first chipsets with the name AMD AMD 580X CrossFire (formerly ATI CrossFire Xpress 3200) and the AMD 480X CrossFire (formerly ATI CrossFire Xpress 1600) that have PCI - Express and support multi -GPU technology ATI Crossfire. As Southbridge are not renamed ATI SB600 is used.
K10
Starting with the processors of the K10 - generation (eg AMD Opteron (K10 ), AMD Athlon X2, AMD Phenom ) began AMD to introduce whole series of chipsets. The first was the backward-compatible to K8 technology AMD 7- series chipset. It was introduced in November 2007.
In March 2010, the first model of the new AMD 800 series was introduced with the 890GX.
On 1 June 2011 was presented with the 990FX, the first model of the new AMD 900 series. The 900 series is fully compatible with the AMD FX processors.

PCI Express chipsets
The following AMD chipsets use the PCI Express protocol (PCIe ) for signal transmission of peripheral devices to the chipset and HyperTransport (HT ) for connecting the CPU to the Northbridge.

PCI chipsets
The following AMD chipsets use the PCI bus for transmitting signals from peripheral devices to the chipset and the Front Side Bus ( FSB ) for connecting the CPU to the Northbridge.
