Intel Core Duo: AOpen i975Xa-YDG to the Rescue

Gaming Performance
The overall gaming performance of an Intel platform for the first time in recent memory is equal to or better than the AMD based platform. These results are indicative of an optimized system as the Intel Core Duo responds very well to the i975X chipset with results from our 945GM platform performing equal to or worse than the AMD system. Considering the additional benefits of lower thermals and power consumption, a compelling case for Intel users can be made for purchasing this platform for gaming. It's worth noting that gaming code these days consists of a lot of integer instructions with much of the floating point work being offloaded to the GPU, and micro-ops fusion certainly appears to be playing a role in the stellar gaming performance of Core Duo.
CrossFire Performance
The performance pattern continues in our CrossFire benchmarks with the Intel platform slightly outperforming our AMD system in the stock settings and overclocked settings. We did note in our test results that CrossFire works extremely well on the Intel 975X platform and on our board once we figured out how to enable it. The instructions for enabling CrossFire on this particular board can be found in our final words sections. Needless to say, it was difficult to figure out, but once set up correctly we were rewarded with excellent scores.

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.
