At an IDF session here today, Intel's engineers confirmed that the roadmap for switching systems over to DDR3 is still on track.
The past year has seen widespread adoption of DDR2 by the industry, as AMD comes on board with its AM2 processors. DDR1 is now in the process of being phased out.
Expect a similarly lengthy transition to DDR3 in the future. The advantages the new memory brings are lower power requirements and more potential bandwidth. As with the introduction of DDR2 over DDR1, DDR3 will likely start out slightly slower than DDR2 and will ramp as the technology progresses.
The first Intel chipsets to support DDR3 will be available in the middle of 2007, supporting 800MHz and 1066MHz. By the end of 2007, we will see 1333MHz modules. What's the betting we see memory manufacturers coming out with 1337MHz modules?
1600MHz will arrive at some point in 2008. In 2009, DDR3 will be the main technology sold with price parity with DDR2 arriving in that time frame.
