It is designed to provide a high performance, high value upgrade path from previous PC133 technology. As the driving force behind PC133, VIA Technologies has embraced DDR, and currently offers the widest range of DDR chipsets for the Intel® Pentium® III, AMD Athlon™ XP, and Intel®Pentium® 4 processor platforms. Available in two different speed grades, DDR enables memory performance to be scaled to fit the performance and cost requirements of a given platform. DDR200 (also known as PC1600) runs at a 100MHz clock speed, and transfers data on both the rising and falling edges of the clock for an effective 200MHz clock rate. DDR266 (or PC2100) uses the same clock doubling technology, but runs at a 133MHz core speed, for an effective 266MHz clock rate. With this clock doubling technology, DDR200 is able to transfer up to 1.6GB/s, and DDR266 a staggering 2.1GB/s. Also, due to its evolutionary, parallel technology, the latency of DDR is quite low compared to competing serial memory technologies. All grades of DDR SDRAM operate at 2.5 volts, as opposed to 3.3V for PC100 and PC133. This lowered voltage allows DDR to penetrate power sensitive applications, such as notebooks and 1U servers. Lowered power consumption translates directly to lowered heat dissipation, again increasing the effectiveness of DDR in mobile and server applications.DDR SDRAM leverages the existing PC133 manufacturing infrastructure, allowing manufacturers to produce DDR266 memory for roughly the same cost as PC133. This price parity with SDRAM will rapidly drive the adoption of DDR as memory bandwidth limitations become more constricting.

Both use standard PGA packaging to reduce the cost of production and allow the use of standard heatsink solutions. VIA ProSavage KN266 North BridgeThe North Bridge of the VIA ProSavageDDR KN266 (model number VT8372) provides support for the 200MHz Front Side Bus AMD Athlon™ 4 mobile processor. Deep pipelining and buffering keep the high-speed system bus supplied with a constant stream of data, maximizing the performance of the processor. This system bus runs in pseudo-synchronous operation with the memory and AGP controllers, providing the low latency of a synchronous design without sacrificing the flexibility of an asynchronous implementation.
