Is DDR2 Ready To Replace DDR1???
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!
It's amazing how fast things change in the computer industry! Between 2002 and 2004 we saw memory go from single channel PC-2700 memory to dual channel PC-4400! The actual bandwidth of DDR1 memory almost doubled, while chipsets and memory controllers kept getting better from generation to generation. So on June 19th, 2004 when Intel finally released the first DDR2 platforms there was concern that DDR2 may not be able to compete with the tried and true DDR1 memory that is on the market today!
Today we bring you DDR2 at speeds from 533MHz all the way up to 733MHz and compare it to some of the best DDR1 memory that is on the market today!
particularly this graph looks great for all those who plan to keep their fast paced ddr1
please do note that comparing ddr400 at 2-2-2-5 with ddr 2 533 at 3-3-2-8 is a just thing seeing that 3-3-2-8 are VERY tight timings for ddr2 @ 533...
quote : "All said and done we learned a lot from benchmarking for this article. First off we found that it was possible for DDR2 PC2-4200 4-4-4 memory to hit low latencies of 3-3-2 (3-2-2 is the lowest possible). Secondly we found out that memory rated for DDR533 by almost all brands overclocks VERY well. A prime example of this was our ability to get an extra 200MHz out of our DDR533 Crucial memory. When DDR1 memory first hit the market you didn't see people overclocking memory 200MHz from the get go! So in terms of being a new product it looks as if DDR2 memory will scale nicely and quickly in the following months. Expect DDR2 memory at 533MHz to be comparable to DDR1 at 400MHz, but don't expect to see any "noticeable" memory bandwidth performance gains till DDR2 667 and above with low timings!"
but seeing that at ddr2 733 we still can't get more power then ddr500 @ cas 3 4-4-8...That means comparing it to ocz EB at 250 would need much lower latencies on the ddr2 733 to come even close...
Prescott has to go higher than 4.5 Ghz to match with any oc'ed Northy at 3.8 Ghz; it means another 12 months before all of the new stuff to get mature. ;)
