Intel 925X/915: Chipset Performance & DDR2

Performance Test Design
With so many changes in the Intel desktop, there were a lot of burning questions to be answered. It seemed a little inadequate just to run a few benchmarks on the new chipsets, or quote performance figures supplied by Intel, so we tried to devise some comparisons that would answer the most common questions that we have heard regarding the new Intel architecture.1. How do the 925X and 915 compare in performance? Is there a significant performance difference in the new chipsets? How does the top Intel system compare to a top AMD Athlon 64 System? 925X and 915 systems were identically configured with Intel 560 processors (3.6GHz) and performance compared with a full set of motherboard benchmarks. We included benchmarks using Dual-Channel DDR memory and the same video card in an AGP 8X flavor on an AMD Athlon 64 FX53 system for comparison. These tests begin on Page 8.
2. How does Intel's new top 925X with PCIe, DDR2, and SATA Matrix RAID compare in performance to a similarly equipped top 875P system? We compared performance of a top 875 with a 3.2 Northwood, GeForce 6800 Ultra AGP 8X, SATA RAID, and DDR 2-2-2-5 memory to the Intel 925X with a 3.2E (775) Prescott, GeForce 6800 Ultra PCIe, SATA Matrix RAID, and DDR2 memory. These tests begin on Page 12.
3. Is DDR2 really faster than DDR? We verified there was no memory performance degradation of the Gigabyte Dual-Memory board compared to Intel 915. Performance with DDR and DDR2 were then compared on the Gigabyte over our motherboard test suite. These tests begin on Page 16.

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.
