Intel Core Duo: AOpen i975Xa-YDG to the Rescue

Disk Controller Performance
The AnandTech iPeak test is 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 our raw files that are 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 I/O 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 I/O operation. In order to make the data more understandable, we report the scores as an average number of I/O 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 I/O operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.
The performance patterns hold steady across both Multimedia Content I/O and Business I/O, with the ULi based SATA controller providing the a 12% improvement in I/O operations over the Intel and JMicron SATA controllers. The ULi IDE controller logic continues to be one of the best IDE solutions, posting scores that are higher than the Intel SATA controller and over 13% better than the Intel and ITE IDE controller.

Hi Gary, just wanted to drop in and give you a kudos on this very nice review!It also makes me smile to finally see Intel catching up with AMD, this can only be good news for the customer...
And a small heads up, there are a few Intel Core Duo Engineering sample CPU's on sale at eBay, "hint hint engineering sample=multipler unlocked"
And also a big thanks for finally posting those capacitor shots and mentioning them, keep up the good work!
Also I think Aopen deserves recognition for designing a mainboard with so high-quality components, Rubycon=Way to go!!!

Thank you for posting these links. :) We have a policy of utilizing the latest driver sets on a supplier's website at the time our testing starts, in this case the Intel general download page is still posting the 7.2.2.1006 driver set. However, I am using the 7.3.1 driver set on our retail board sample tonight. ;-)irev210 - Sunday, May 7, 2006 - link
Hello Gary,Sorta funny how that other fellow has absolutely no idea what he is talking about.
I just wanted to touch upon something that I didnt see get much attention.
You should have mentioned in your article about how efficient the core architecture is, and how well it scales with increased frequency. The chip turns into a total monster once you get past 3ghz, and continues to perform better and better as you increase the speed. The fastest I could get on air was around 3.1ghz. I wouldnt be afraid to crank the volts to the 1.5 max on the aopen board... with a different cooler, you should hit some nice speeds. Try swapping out for a zalman 9500, or a big typhoon.
The shortfalls, are as you mentioned the southbridge lacking raid, and the poor bios options. Vcore should let us up to 1.65-1.7, while Vdimm should let us do atleast 2.3.
While this may not satisfy the most serious enthusiast, this board does fill a nice niche. The price is pretty high, but core duo CPU's can be had on the cheap, which makes up for it. For someone that is worried about their electric bill, and wants performance and performance per watt, this is a great alternative.
For others who must have the fastest. This just makes them drool. This is the low end of the core architecture. Merom and Conroe to follow... we shall be stunned.
Consdering Meroms being tested now at 3.0Ghz are faster than 3.2Ghz Yonah's... AND YOU WILL SEE Conroe EE at 3.33 w/ a 1333fsb doing 4ghz w/ 1500mhz FSB :)
For those that dont get it yet... AMD will need a AM2 processor running at about oh 4.8Ghz to beat a 4Ghz clocked conroe :)
Good things to come. I take no sides, im just excited about new stuff :)

How come a ~1 % cpu usage translates into a massiv 20 fps drop in BF2? Looks like EA have a deal with Creative :(A lot of world records have been beaten with this mobo already over here at XS :)
coolaler even got SLI enabled on it ;) also running a merom in it ;)
Your 266 FSB is very good and about normal for aircooling. Give it some cold and it will go further ;)

[font color="#000000] (Damn white text. Nice comment engine AnandTech.... Need a new programmer?)Because RightMark is a theoretical test and not actually a real game or audio application. Also, look at the 3D/EAX scores - it's more than 1% CPU usage, but still less than 20% or whatever.
Gary Key - Thursday, May 4, 2006 - link
It has to do with the Realtek driver load and Creatives to some extent being split between the cores during the RightMark testing. I noted in the text that although the cpu utilization is extremely low in our Rightmark results due to the load balancing that the actual game results (percentage differences) were basically the same as our single core scores. The drop in BF2 is due to the audio algorithms being generated by the CPU rather in hardware as on the X-FI card. Our audio settings in BF2 are set to hardware, medium quality, EAX enabled, the high quality setting extracts another 6FPS but we generally have not noticed an increase in audio quality. This is one penalty you pay for on-board audio in a CPU limited game although Serious Sam II is the one exception for either solution.
We are hoping to receive a T2700 chip from Intel shortly and will "chill" it to see what results come from it. :) Yes, we had SLI working on the board also, but that is a topic that will be buried with Jimmy Hoffa at this time. ;-)

Intriguing last 2 sentences.The comments section has some really good info alot of the time :).
And kudos for bringing into the review something about the penalty for using onboard audio versus dedicated hardware.
You're not by any chance planning on writing something about audio quality some-time? Not that im an audiophile or the like, just curious.

We will expand our audio section in the next update to our motherboard review section. We are looking at several variations of the review process as we enter a very busy time of the year with AM2, Conroe, and others all launching over the next 90 days. :)
