Did i miss something or i did you guys just compate ddr1600 at 1333mhz to super expensive ddr2 and crank down the latencies too 3-3-3-8 at 800mhz and compare that to ddr3 at 1333?
where is the 1600fsb test?
where is the 1700mhz?
or the 1800?
everyone knows you must crank ddr3 up to 1600-1800mhz to get the memory bandwidth boost
did i miss something?
added 4/12 quote from andantech on the 790i chipset article was released last week:
"DDR3 prices have also made the idea of moving to either X48 or 790i a whole lot less painful than it would have been just a few short months ago. Great clocking and relatively inexpensive 2GB kits of DDR3 are starting to show up at all our favorite online retailers. We were able to find 2GB kits like the Patriot Viper rated at DDR3-1600 with 7-7-7 timings for under $200 without too much trouble. To date, all of our experiences with DDR3 memory have shown the DDR3-1600 kits to be incredible performers when it comes to overclocking"
this quote is directly the opposite of THG results - this quote is also the real results
Anandtech: "If you're still buying DDR2 and you're serious about overclocking, you're buying yesterday's technology. That might be fine for the price-conscious enthusiasts, but if you're considering the purchase of a $300+ motherboard and $1000 CPU we have to strongly recommend making the move to DDR3. "
ddr1600 pushed to 1700-1800 results in a 15% increase in 3dmark06 scores with a quad crossfire 3870, 3.6ghz q6600 system from 19000 to 22000, corsponding increases in apps should be expected.
I came away from the article feeling pretty good about my DDR2 1066mhz 188.8.131.52, especially since it was 4gigs for $99.00. This seems to be the issue every time a new standard of DDR is released. When DDR went to DDR2 we were seeing the same benchmarks. AMD really likes tight timings because of the integrated memory controller, even Intel likes tight timings to an extent. Once Nehalem is released Intel will be in the same boat as AMD, tight timings will generally give better performance over higher clock speeds. I remember when DDR2 was released, they said it was going to be a short stop over before DDR3. Lets hope DDR3 sticks around a little longer. I see that Nvidia might be going with DDR5 in the very near future which makes me think DDR4 might go by as quickly as DDR2. I think even running the highest clock speeds available in DDR3 rarely boost performance enough to notice outside of a benchmark. DDR3's real potential will be seen much like DDR2's at the end of its cycle.
I think the point was DDR 2 800 is 98% as fast as the fastest DDR3 in most applications. The fact is that Intel chips don't need the extra bandwidth. I doubt that AMD results would be all that different.
To the OP they tested cheap DDR2 as well. Do you use DDR3 or something because a 200MHz boost isn't going to change the results very much?
I could care less about that DDR3 money furnace at the time being. I did enjoy seeing the CL4 vs CL5 for DDR2 however.
I agree though, drawing conclusions from tests on one RAM sample does not validate statements regarding the entire DDR3 population. On top of that, their RAM selection isn't even from the same companies....huh? I can think of a better way to organize the test of DDR2 vs DDR3 too but the article is what it is. I think the most informative and accurate info comes from the timing comparisons performed with each RAM sample like the latency changes in DDR2.
The conclusions that are drawn between DDR2 and DDR3 are only relative to Patriot PDC32G1600LLK DDR3 and Corsair Dominator CM2X1024-8888C4D DDR2, not the entire DDR2 and DDR3 population. So the actual conclusion should say "In our tests, this Patriot DDR3 is comparable to this Corsair DDR2" not "DDR3-1066 and -1333 memory do not yet result in better performance (than DDR2 800)" That is a very sloppy conclusion.
i think the point thats been made is that it doesnt matter. small differences exist between a huge range of frequencies and speeds on the core 2. Something else - namely chipset and processor limits everything. We will see some difference between them on amd stuff or intels next gen but amd doesnt have a ddr3 solution so this article serves as a discrete Intel platform specific statement that it doesnt matter
