DDR2 vs. DDR: Test Configuration
While the 925x/875 benchmarks indirectly compared DDR and DDR2, the Gigabyte 8GPNXP Duo is potentially the perfect platform for directly comparing DDR2 and DDR performance. It is an Intel 915 Socket 775 board that supports both types of memory in a dual channel configuration. First, we took a closer look to see if this design provided any performance penalty in providing support for either DDR or DDR2. One easy, but effective, way to check memory performance among boards is with a utility called "Aida 32", available as freeware from many download sites. Aida 32 has a unique memory test that measures separately read and write memory operations and then provides a composite score.Aida 32 results were compared on all the motherboards used in these benchmarks.

It appears that the Gigabyte actually has faster DDR2 performance than either Intel motherboard. While this is very interesting and worth exploring in our future 915 roundup, it is not really important for this DDR2 and DDR comparison. The Aida 32 results clearly show that the DDR2 performance on the Gigabyte is not penalized by the dual-memory design.
Another very interesting test result, and totally unexpected, was that DDR memory actually performed faster on the Gigabyte 915 than on the Asus P4C800-E, which is noted for its very fast memory performance. This is something worth exploring in the future because it may mean 915 boards will run DDR faster than current 875/865 boards. One result is not enough to draw a conclusion, but we will explore this further in our upcoming Intel 915 motherboard roundup.
The Aida 32 results certainly indicate that the Gigabyte Duo is a valid platform for comparing DDR2 and DDR performance on the Intel 915 platform.
| Performance Test Configuration | |
| Processor(s): | Intel 540 (3.2GHz) Socket 775 |
| RAM: | 2 x 512MB Micron DDR2 533 2 x 512MB OCZ 3200XL DDR (Samsung 2-2-2-5) |
| Hard Drive(s): | Seagate 120GB 7200RPM SATA (8Mb buffer) |
| Video AGP & IDE Chipset Drivers: | Intel Chipset Driver 6.0.0.1014 |
| Video Card(s): | Gigabyte nVidia 5759 PCX |
| Video Drivers: | nVidia 61.45 Graphics Drivers |
| Operating System(s): | Windows XP Professional SP1 |
| Power Supply: | Powmax 350W |
| Motherboards: | Gigabyte 8GPNXP Duo (Intel 915X) Socket 775 |
Since comparisons of DDR and DDR2 were on the same platform with identical components, the system was configured as you might purchase a mid-range Intel 915 system. Graphics are provided by a mid-range nVidia 5750 PCIe graphics card with no need for auxiliary power, the CPU is a mid-range 3.2, and the power supply is a very common 350-watt with a 20-pin ATX connector attached to the 24-pin power socket. Our goal here is to compare 915 DDR to 915 DDR2, but the test results also provide a picture of typical performance that you can expect with a mid-range 915 system.

I am with #4 and #16, it is OK to leave the Northwood, but this is not apples to apples if you did not use two Prescotts to compare the boards to get a percentage difference in the architecture. The 'weak' areas almost match up to a Prescott vs Northwood comparison. It does not tell anything. Sorry Wesley, but the conclusion is flawed on a direct comparison.Bozo Galora - Saturday, June 19, 2004 - link
and notice the alderwood gigabyte only has the single red intel IDE, no greenieshttp://www.tomshardware.com/motherboard/20040619/i...

Tom's says new Intel chipsets are O/C locked - tied to PLLhttp://www.tomshardware.com/hardnews/20040619_1103...

Am i missing something or is intel not as familiar with there own products as ATI...ie just read about ATI's chipset optimized for prescott and its faster than northwood which is a change from most benchmark comparisons on other boards ...http://www.anandtech.com/chipsets/showdoc.html?i=2...

Combined with the fact that they gonna start putting all this new tech on BTX format, Intel is really trying hard to completely remove itself from the DIY market. And although your average computer buyer doesn't even know what an AMD processor is, you can bet that OEM's are too happy about being asked to either a) swallow the cost of these upgrades or b) raise prices and lose customers, and this might make them eye AMD as a way to shore up the bottom line. Being a trendsetter is one thing but bringing in DDRII when it's slower and PCI-E when it offers practically no benefit isn't exactly blazing a trail that I want to follow...JustAnAverageGuy - Saturday, June 19, 2004 - link
"AMD is too pricey and Intel performance is pathetic"I can honestly say that is the FIRST time I have ever read that phrase.

from what i've read on ddr2 it won't start make a big performance difference unless its clocked almost twice the speed as the ddr1 your compairing it to due to the fact all ddr2 is is 2 ddr1 chips dual channeld run thru a buffer. so when your running at 400mhz ddr2 the latency is the same as ddr200 due to the speed the chips are running at not the external frequency.Marlin1975 - Saturday, June 19, 2004 - link
"AMD is too pricey"WTF?
You can get a Athlon64 chip for less then $199 now and there is a sempron 3100+ socket 754 chip that has a MSRP of only $124
AMD hsa the best bang for the buck if you want low/mid end (atlon XP) or even mid/high end (Athlon 64/fx)
I went from a 800Mhz FSB HT P4 to a Athlon64 and and glad I did.

"AMD is too pricey and Intel performance is pathetic"I agree socket 939 is way overpriced, especially for the underdog AMD who has an opporunity to make real enroads into the market with Intel down right now... but the rest of this is untrue. Socket 754 3200+ is the same price and P4 3.2 and they split the benchmarks. I'd argue for gamers the A64 3200+ is underpriced. Then intels performance is just fine unless you call 5-10% differences here and there signifigant. I don't and i doubt you'd even notice without charts to prove it.

"AMD performs great till you give it too much to do at once, and they won't fix that till they bring in dual core."Every processor is like this, Hyper-Threading doesn't save any Intel chip from this same thing. Benchmarks like Winstone, etc are benchmarking with multitasking in mind.
"AMD is too pricey and Intel performance is pathetic"
lol, it's ironic, but I'm glad AMD is where they are. They certainly aren't the same company there were 8 years ago.
