DDR2 vs DDR1

Legit Reviews have thrown up their DDR2 vs DDR1 Memory shootout article. Check it out.
To get a better understanding of DDR2 memory we need to go back to when it all began! It was back in October of 2002 that things started looking good for DDR2 memory and that it would actually become the successor to the DDR1 memory line. This is back during the time period where enthusiasts were running single channel DDR1 PC-2700 memory! So on paper DDR2 PC-4200 was a huge performance leap in raw bandwidth power, but was also meant to improve memory latencies and lower the overall power consumption. It was the goal to bring DDR2 out at PC-3200 and PC-4200, while lowering the voltages down to1.8V! As you can tell DDR2 533MHz would be a huge performance leap over DDR1 333MHz! The designers were happy and went off to build DDR2!

    Conclusion:

    1. DDR2 runs hot
    2. DDR2 uses more voltage than JEDEC had ever wanted
    3. DDR2 runs unacceptably high timings
    4. DDR2-667 is only 59MB/s faster than DDR500.
    5. DDR2-533 is NOT faster than DDR400.
    6. DDR1 is better than DDR2 with a 133-167MHz deficit.
    7. DDR2 sucks.

    You forgot one.
    8. DDR2 is twice the price compared to DDR1.
    At least in the beginning, prices will drop eventually.

    Oh, good #8! :D

    DDR2 is at the begining of its learing curve.

    DDR1 at 1000 (2.5-3-4) on a 875P mobo will give you this http://www.anandtech.com/memory/showdoc.aspx?i=2098&p=9
    DDR2 at 1000 (4-4-4) on a 925X mobo will give you this http://www.anandtech.com/memory/showdoc.aspx?i=2112&p=17
    Not too bad.
    There are still a bunch of unanswered questions, but look how far DDR1 has come.

    No, I don't like the price.
    The slow timings and async operation bother me also.
    But this is the horse to watch.
