AMD chipsets
In addition to processors , AMD also offers chipsets for these processors. Originally, AMD did not see as a supplier of chipsets, but has repeatedly offered its own or purchased chipsets at certain times to motherboard manufacturers to facilitate the transition to a new generation of processors and gaps in the range of chipset manufacturers such as NVIDIA , VIA , SiS and ULi to bridge. After purchasing ATI Technologies in 2006, AMD fully integrated these chipsets into its own product range.
history
K6
It started with the AMD-640 , which was suitable for socket 7 CPUs and was supposed to support the sale of the AMD K6 . This chipset was just a relabeled VIA Apollo VP2 / 97 . The AMD-645 offered as Southbridge was a relabeled VT82C586B .
Actually, the AMD-640 was supposed to be followed by a chipset with 100 MHz FSB and AGP to support the concept of Super Socket 7 for the AMD K6-2 (it would probably have been a VIA Apollo MVP3 ), but this chipset was never used brought the market.
Athlon
With the beginning of the K7 generation (AMD Athlon), AMD brought the AMD-750 (code name: Irongate ) onto the market, which consisted of the AMD-751 Northbridge and the AMD-756 Southbridge. However, the VIA 82C686A was also used very often as a southbridge, as it was better equipped.
The AMD-750 was very important because no other suitable chipset was available for the Athlon's EV6 bus protocol, which is derived from the Alpha processor . VIA Technologies had n't finished the KX133 yet and the other manufacturers waited first.
With the change to DDR-SDRAM and the introduction of the AMD Athlon MP , AMD also brought the AMD-760 series onto the market. This consisted on the one hand of the AMD-760 (AMD-761 Northbridge and AMD-766 Southbridge) for the AMD Athlon and AMD Duron and on the other hand of the SMP-compatible chipsets AMD-760 MP (AMD-762 Northbridge and AMD-766 Southbridge ) and AMD-760 MPX (AMD-762 Northbridge and AMD-768 Southbridge) for the AMD Athlon MP. However, the VIA 82C686B was again used very often instead of the AMD766 Southbridge .
Athlon 64
With the market launch of the AMD Athlon 64 and the AMD Opteron , AMD again had the appropriate chipsets ready with the AMD-8000 series , which should facilitate the new platform change. This time the chipset manufacturers were significantly faster and so the AMD-8000 series was mainly installed on server and workstation mainboards.
With the AMD-8000 series, AMD relied entirely on HyperTransport as the chipset connection and therefore one can no longer really speak of North or Southbridge, since the individual chipset elements were only HyperTransport bridge chips ( tunnels ), which are combined depending on the requirements could become. There were the following chipset elements: 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 closely comparable with the classic northbridge , while the AMD-8111 largely corresponded to a classic southbridge .
After that, it was temporarily silent about AMD chipsets. With the purchase of ATI Technologies in 2006, AMD got a complete line of chipset products, including IGPs , back in hand. ATI has been fully integrated with AMD. Products for the own platform have been partially renamed; Products for Intel platforms continued to be marketed under the ATI brand name.
The first chipsets with the name AMD were the AMD 580X CrossFire (formerly ATI CrossFire Xpress 3200 ) and the AMD 480X CrossFire (formerly ATI CrossFire Xpress 1600 ) which have PCI-Express and support the multi-GPU technology ATI Crossfire . The not renamed ATI SB600 was used as the south bridge.
K10
Starting with the processors of the K10 generation (e.g. AMD Opteron (K10) , AMD Athlon X2 , AMD Phenom ), AMD began to present entire series of chipsets. The first was the AMD 7 series chipset , which is backwards compatible with the K8 technology . It was presented in November 2007.
In March 2010, the first model of the new AMD 800 series was presented with the 890GX .
On June 1, 2011, the 990FX, the first model of the new AMD 900 series, was presented. The 900 series is fully compatible with the AMD FX processors.

PCI Express chipsets
The following AMD chipsets use the PCI Express protocol (PCIe) to transmit signals from peripheral devices with the chipset and HyperTransport (HT) to connect the CPU to the Northbridge.

- ↑ CrossFire is not supported by the chipset according to AMD. However, there are some motherboards with x16 + x4 or x8 + x8 CrossFire lanes.
- ↑ The 760G supports both DisplayPort and HDMI signals for video output, but the implementation depends on the respective mainboard.
