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.

#22 & #23 - This will all make more sense when Derek's companion piece is posted later today, which compares the 3.6, 3.4EE, and AMD chipsets.There is no 3.6EE, and we considered comparing the 3.4EE, but the early benches showed the 3.6 to be a fairer comparison. The 3.6 is the only new Intel chip and the top (3.4EE is just a new 775 package launch) and the FX53 is the top AMD chip. The FX53 runs at the same speed as the 3800+ (2.4GHz) but has twice the cache, and both are Dual-Channel Socket 939. The FX55 will not be released until late this year.
Comparing last year's 3200+, the first Socket 754 Athlon 64 and single-channel, to the just-released 560 (3.6GHz) compares nothing.

If the chipset supports only one IDE channel, why does the Gigabyte board have two green IDE sockets.Am I missing something?
I really wanna know, because only one IDE means I dont buy this stuff.

So when are the dual core cpu's coming out? Think ill wait for those.SDA - Saturday, June 19, 2004 - link
That's just it, though, the FX-53 is just a few tens of dollars more than the 3800+, so some people figure why not? AMD is overcharging because they know they can get away with it..stephenbrooks - Saturday, June 19, 2004 - link
Maybe replace '3500+' by '3800+' above.stephenbrooks - Saturday, June 19, 2004 - link
One interesting thing is the difference it makes which AMD chip people compare the 3.6E to in these reviews. Before coming here I read the one at http://www.bit-tech.net/review/326/ and came away thoroughly impressed. The clincher was that they compared to the A64 3200+ whereas this review compared to the FX-53.I'm not totally sure if the 3.6E _should_ be compared to the FX-53, being as it is marketed as a '560', in the 5xx 'mid-range' desktop segment for Intel. A better comparison for the high-price-end might be 3.4/3.46EE vs. FX-53 or '720' vs. FX-55 later on.
I'd think 3.6E vs. A64 3700+, or even better the 3500+ (as it's on AMD's new socket too) would be an informative comparison. It's just a shame Intel's high-end offerings are a bit thin on the ground right now.

Good review. I wish you had compared the 875 with the 925x however both using a Presscott CPU. With one using a Northwood and one using a Presscott fails to show which chipset optimizes the power of the CPU. The fact that you didn't further inphasises that Intel is in one hellava drought. The 3.2 Northwood/875 combo that came out like 8+ months ago is still faster than ANYTHING they have released.I am waiting for a reason to upgrade but this sure isn't something I was looking for. With Intel having these troubles, AMD is going to take their sweet time putting out anything faster.

It would be great to see the 915 with Skt478- best of both worlds. I know that Skt775 is appearing on 865 mobos (Abit AS8). At that last Taiwan computer expo they had dual intel Sckt mobos but were they 915s?rjm55 - Saturday, June 19, 2004 - link
#16 - I disagree with you. I think Northwood on 875 is exactly the right comparison to Prescott 775 on 925X. Both at the same speed as done in the review. Prescott was not designed for 875, so comparing the best last generation 875/Northwood to the new 925X/Prescott is extremely fair. I'm sure Intel would have preferred a comparison of Prescott to Prescott, because they would have looked better. I think that was #4's point, which you apparently missed.Doormat - Saturday, June 19, 2004 - link
Now I dont feel so bad about buying that P4-3.0C/i875 combo last month...
