Canterwood/Springdale: bad performance because of no Intel Application Accelerator support?!

Hi,

I intend to buy a PIV 800Mhz FS with Asus P4C800 or P4P800 with Canterwood or Springdale chipset, but in a review with benchmarks at AnandTech they say following: "Here we see the unfortunate effects of not having Intel Application Accelerator
support for the new ICH, thus the 875P falls behind even the 845PE; updated drivers will fix this issue." (see: http://www.anandtech.com/chipsets/showdoc.html?i=1811&p=10 to see the benchmark with there comments)

I don't know exactly what Intel Application Accelerator is (I believe it has something do to with drivers but perhaps somebody can please clarify this), but apparerently support for it seems crucial as it can make a huge performance difference if you see that in some benchmarks the 875P even falls behind the 845PE! Hasn't Intel fixed this by now, as it seems to be something very important that can really make a big difference in performance?! I don't understand that they didn't think about this when releasing the chipsets?!!

Can anyobody please clarify what this is all about, and if it makes sense not to buy a Canterwood or Springdale system until this problem has been fixed?! Anybody know when this will be fixed and what you will have to do in your system to fix it?!

Thanks in advance for all good feedback!

Mike.

intel AA is just a heavily optimized IDE driver IIRC

and they will be out for the chipsets just give it time

The IAA are a set of IDE drivers for the i8xx chipsets. They are very aggressively written and can provide substantial performance increases in certain cases.

The latest IAA version, 3.0, is designed for use with ICH5-R with drives in a RAID 0 array.

The previous version, 2.3, does not support ICH5.

If you have drives which are not in a RAID array using the ICH5-R, or just the regular ICH5, then you cannot use any version of the Intel Application Accelerator drivers.
