Intel D975XBX: Intel brings their Bad-Axe to Market

Disk Controller Performance
With the variety of disk drive benchmarks available, we needed a means of comparing the true performance of the wide selection of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs. the World. The iPeak test was designed to measure "pure" hard disk performance, and in this case, we kept the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive.
We played back Anand's raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's iPEAK utility was then used to play back the trace file of all IO operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance differences to the controllers that we were testing, we used the Maxtor MaXLine III 7L300S0 300GB 7200 RPM SATA drive in all tests. The drive was formatted before each test run and a composite average of 5 tests on each controller interface was tabulated in order to ensure consistency in the benchmark.
iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned as it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.
Our testing results in RAID 5, 0, and 1 with the Intel ICH7R was successful, but we did not have time to properly complete testing of the other storage controllers for this article. We will have published RAID results for all tested boards in our 975X roundup along with results from the NVIDA based P5N32-SLI.

Actually, depending upon the device PCI-E does support single-ended transfers. I probably should have worded my statement differently.

It's pretty sad Garys great article is'nt being read more - only 16 replies almost two days later - he can blame intel and thier non-exciting chips ATM.Gary Key - Friday, January 27, 2006 - link
I should have put "Conroe Comes to Town" in the headline. ;-) At least the board is showing the 1333 fsb setting, hint, hint. Intel's products are a little mundane at the moment but at least we have 20 replies now, anything less and I owed my dog a Big Mac.danidentity - Thursday, January 26, 2006 - link
Do you guys plan on doing a 975X motherboard roundup in the future? If so, when is it going to be ready?Gary Key - Thursday, January 26, 2006 - link
We have three more 975x boards to review. I estimate in about three weeks the roundup will be ready.

Thanks Gary. Also, is there any word on whether 975X will support Conroe?Gary Key - Thursday, January 26, 2006 - link
We continue to ask this question. As soon as we have an answer it will be front page news. :-) This board officially supports the 1333 fsb that we will see on product launches this summer but whether they will respin the 975x or not is up in the air right now.

The lack of performance, specialy when compared to an AMD similarly priced system should be compensated with a richer array of features. Looks like intel failed at that. Couple that with a higher energy bill, hotter/noisier computer and there you may explain why so many people now have AMD systems. For me, my last intel PC was a Pentium III. It was good for over 7 years, went from my home to my office untill a cheaply configured Sempron recently put it out of it's duties.AGAC - Thursday, January 26, 2006 - link
Can enyone tell me why? Is this "William Shakespeare inside" some spiner's new trend? And while we're talking about intel's marketing strategy what's all the hype with this viiv thang?
