Intel Core Duo: AOpen i975Xa-YDG to the Rescue

Synthetic Graphics Performance
The 3DMark series of benchmarks developed and provided by Futuremark are among the most widely used tools for benchmark reporting and comparisons. Although the benchmarks are very useful for providing apple to apple comparisons across a broad array of GPU and CPU configurations they are not a substitute for actual application and gaming benchmarks. In this sense we consider the 3DMark benchmarks to be purely synthetic in nature but still valuable for providing consistent measurements of performance.
In our first tests, the combination of the Intel Core Duo and AOpen i975Xa-YDG makes for an impressive showing against the AMD Opteron 165/175 and Asus A8R32-MVP setup at both stock and overclocked settings. The Intel platform had no issues running the full 3DMark series when overclocked but our AMD platform struggled at first until we dialed in the right mix of voltages and memory settings.
General System Performance
The PCMark05 benchmark developed and provided by Futuremark was designed for determining overall system performance for the typical home computing user. This tool provides both system and component level benchmarking results utilizing subsets of real world applications or programs. This benchmark is useful for providing comparative results across a broad array of Graphics subsystems, CPU, Hard Disk, and Memory configurations along with multithreading results. In this sense we consider the PCMark benchmark to be both synthetic and real world in nature while providing consistency in our benchmark results.
The margins are closer in the PCMark05 results but the Intel platform continues to show an advantage over the AMD platform at stock and overclocked settings. It is obvious from our test results that we can expect even greater results from the Conroe and Merom processor series.
Rendering Performance
We have added the Cinebench 9.5 and POV-RAY 3.6 benchmarks as they heavily stress the CPU subsystem while performing graphics modeling and rendering. We utilize the standard benchmark demos in each program along with the default settings. Cinebench 9.5 features two different benchmarks with one test utilizing a single core and the second test showcasing the power of multiple cores in rendering the benchmark image. We had planned on generating 3dsmax 7 benchmarks but our AMD platform would not complete the underwater benchmark. We are still investigating this issue.
The Intel Core Duo desktop platform showed its strength in the extremely demanding POV-RAY benchmark, bettering the AMD platform by 18%. In our limited testing with the Asus N4L-VM featuring the 945GM mobile chipset our stock Intel Core Duo numbers were slightly better than the AMD platform in the Cinebench 9.5 benchmark and only about 6% greater in the POV-RAY benchmark indicating AOpen's choice of the i975x chipset certainly makes a difference in the performance ability of the Core Duo.

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.
Gary Key - Friday, May 5, 2006 - link
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. :)
