The DDR freight train will be adding some locomotives...

DDR-II

jedec.org

What is the JEDEC Future Dram Task Group?
Established: 4/1998 by JEDEC JC-42 Memory Committee
Scope: Define and develop a long term roadmap detailing the logi-cal,
physical and electrical interfaces of future Drams and
DIMMs.
Participation: Over 50 companies with expertise in the following:
• Dram manufacturing
• Dimm manufacturing
• PC chipset design
• Microprocessor design
• Server/mainframe/super computer design
• Communications
• Graphics
• Consumer electronics
• Packaging
• Connectors/interconnect
• Support chips
• Modeling
• Test Equipment
Current Task: Develop DDR II Dram and aid the JEDEC committees
during the standardization process. The JEDEC
committees make the standards, not the task group.
Methods: Bring together a diverse group of companies and engineers
• Everyone, including non-JEDEC members, are welcome to join
• Open forum for sharing new and old concepts
• Education of the group though the guest speakers
Goals: Open standard - Its FREE!
• Low system cost
• Ease of Manufacturability
• High volume

DDR4800

What is DDR II?
• DDR I Backwards Compatibility
• Performance/Bandwidth Improvements
• Cost Improvements
• Power Reduction Improvements
• I/O, Package and Clocking

Put the CRACK pipe down! You frying your brain. Links show 10 to 30 % on average and even some 50+% improvments.

Sylvester,

As you can see, the average performance difference is about 10% depending upon the benchmark.

10% improvement is a good news. For example, an increase in clock speed for 1.2 GHz to 1.3 GHz is about 5%, so using Athlon 1.2 GHz with DDR you get a performance that's almost as good as if you bought 1.4 GHz Athlon.

By the way, 10% performance increase vs. PC-133 SDRAM is much better than a performance decrease you get when using Rambus.
