acquisition of ATI, they have been pushing a lot more to get back into the chipset business, particularly on the desktop end. With that, new details regarding the upcoming RS780 chipset have been released
Most notably, the new chipset will be based around the AM2+ processor and features a HyperTransport 3.0 bus, remote management support on the business end, a redesigned south bridge and UVD support. Important for low-cost machines or business machines, the onboard GPU that can come with this chipset will be capable of using dedicated memory, a significant advantage over shared memory designs.
Other than that, there's nothing particularly impressive to note about it. All PCIe host support moves into the RS780 natively, with the south bridge (SB700) handling only PCI and other I/O such as the SATA ports, of which the SB700 supports a total of 14.
Considering how brutally amazing the nForce series of chipsets has been for quite some time now in the desktop market, particularly amongst enthusiasts, AMD is going to have a hard time cracking the ice there.
