AMD give me more pleasure dan excitement. Overclockable is the reason why i use AMD. This blog is formed as my thanks to AMD

ATi AMD RS690 + SB600

October
We can say this chipset represent the first time chipset which carrying AMD name. Even if it’s wrong, this chipset will remain to be first AMD chipset that has integrated graphic that full supporting the graphic of Windows Vista OS.

This is will become a big change among the OEM, and market retail. It is true, in this time RD485 chipset solution which arming the GPU X300, work good enough to run Vista. However, surely a GPU X700 will do it better. ATI is already having entered the final step, in develop of RS690 chipset. And so all the motherboard manufacturer, it's already finished their design. In average the motherboard producer will use the RS690 chipset as Northbridge, and with SB600 as Southbridge.

In this time, SB600 Southbridge has attended and ready for show off and motherboard Sapphire Pure Crossfire Northbridge PC-AM2RD580 product is one of the motherboard that used the SB600 chipset. As the next generation chipset, RS690 will use the GPU core integrated with Radeon X700. Architecturally, with the packaging of a GPU chip into motherboard chipset, there will be the cutting of pipeline unit in GPU X700; from 8 units become just 4 units. This happen because falling short of packet space of a chipset to accommodate all X700 core, which have 120 million transistor.

Integrated graphic of Ati, previously only have two unit of pipeline. So, with just only four units pipeline seems sensible enough. This Chipset also support the speed of Hypertransport till 2.0 GHZ, Dual Channel DDR2 800 MHZ by providing four slot, one slot of PCIE x16 and Southbridge or other chip addition, make it has SATA II interface, HD Audio 6-channel, PCIe and Gigabit LAN connection.
