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.

Believe it or not, people can run 64bit apps for other reaons from 4GB memory...such as increased performance? I knwo not many apps right now show increased perofrmance with 64bit mode, but some do and I believe this will go up when more developers start programing for it with more intensity and all that.Jason

For me this is the showstopper, and the reason I much prefer Turion at present.Core Solo/ Core Duo are 32 bit only. That makes them quite rarely disadvantaged - even the new Celerons can do 64 bit EM64T.
This board would be of much more interest if the review said "THIS BOARD IS MEROM-READY". As it doesn't, I assume it isn't. The review here might have highlighted this important issue which will be crucial deciding factor for some potential purchasers, especially considering the price.
I see Conroe and Merom systems quickly filling the market need this board is targetted at.

Only disadvantaged for those utilizing 64-bit applications and operation systems, but for 95% of the marketplace they are fine. Not that I do not think it is an issue, but one that is way overblown in today's marketplace.
Probably in a couple of years it will be completely different but for now, 32-bit applications are still king of the hill (market share wise). This upsets me as I have to believe the entire migration path should have been completed by next year but the foot dragging between Microsoft and Intel negated AMD's advantage in this area for far too long. With that said, Merom takes care of the Yonah 64-bit issue in the mobile sector for Intel in a couple of months. It will be very interesting to see how it compares to Turion 64 X2, it will be good for all of us to have choices in the mobile sector.
We cannot quote on whether this board is Merom approved or not until qualification testing is complete. Will a Merom T7400 work in this board with the bios 1.3b, yes it will, and the initial results show a great deal of improvement over Yonah in certain benchmarks. Will Merom be fully supported by Intel and AOpen on this board, we do not know yet. AOpen is waiting a production spin of Merom before trying to the qualify it on this board and even then Intel might force everyone to Crestline for official support. We are still trying to figure out if Merom is going to work with 945GM as stated a couple of months ago. The entire situation is so up in the air right now that any statement has the potential to be wrong so being quiet is the best possible option. :)

from the spring idf article on AT:Now that may not be a 100% promise, but until Merom is actually released, there's no way to be 100% certain any given board will work with it.

You mean 4GB or greater...at 4GB, a 32bit processor will be using PAE already.
And yes, I find that 4GB is a great help on a number of my apps...

Mobile/SFF apps?Name them.

Photoshop CS2, Premiere Pro, and Mental Ray...

I'm a heavy Premiere user, and I can tell you it's a 32 bit app.Chadder007 - Thursday, May 4, 2006 - link
You can still run it under a 64 bit OS and have access to the 4gb or greater amount of ram.defter - Thursday, May 4, 2006 - link
No you can't. If you have an 32bit software then it can only address 4GB of memory.
