The Platform: Intel 955X

AMD's dual core Athlon 64 processors will work in all current Socket-939 motherboards with merely a BIOS update. The same level of compatibility obviously isn't true for Intel's dual core solutions.  You'll need a new motherboard to support the Pentium D and Pentium Extreme Edition chips, and thus, Intel shipped us a board based on their soon-to-be released 955X platform. 

The platform boasts a dual channel DDR2-667 memory controller, but given that the chips still only support an 800MHz FSB, the added bandwidth of DDR2-667 is useless.  Even for bragging rights, running at DDR2-667 doesn't make sense, as the memory that Intel shipped with the system is rated at 5-5-5-15 timings at 667MHz.  Wasted bandwidth and higher latency memory is nothing to get excited about in our book.  We're not entirely sure what Intel is up to, but they had better plan on increasing the FSB of their chips really soon if they want DDR2-667 (or even 533) to gain any sort of acceptance. 

Other than support for dual core, faster DDR2, RAID 5 and 8GB of ECC memory, the 955X doesn't have any features to boast over the current platforms. It does look like Intel may be planning SLI support for the 955X however:


The 955X board that we received had two physical x16 PCIe connectors, but only one of them was electrically a x16 slot.

Despite Intel's warnings not to make any judgments about final performance or stability, both the 955X and the Pentium Extreme Edition were as rock solid during our testing as any product that we've encountered.  This was quite possibly the most stable encounter with a pre-release CPU, chipset and drivers that we've ever had.  That being said, we really didn't expect Intel to break tradition with a platform of which they weren't 100% sure.

    I now put the Inquirer on the same level as CNN. Fox News is a better comparison.

    Sorry.. how about a lightwave scene rendering at the same time as running a filter on a large image in photoshop.

    Can we see Lightwave benchmarks again please?

    As always, I appreciate the comments and support, but let's not let this get too off topic. Keep the requests for tests and new scenarios coming, I can't promise I'll get all of them included but I'll do my best to incorporate as many ideas as possible.

    Take care,

    ANAND!! lol...shoot to bad you already finished part to, but for all those whiners, who want games, i have to say this...

    The only gaming benchmark that would make sence is running a game while having a firewall and antivirus running....most TRUE(not you wannabe's who run firefox in the background to induce lag in fps) gamers(including me) turn off their firewalls and antivirus to get the very best possible performace, because it matters...no one multitasks with games...

    Now when you all flame about how you multitask with games, and "speak for yourself shit" let me just say, are you really going to shrink a DVD while playing Counter Strike??? YOU'D GET OWNED....

    I do not see any point in benchmarking games as thesse people mentioned...they failed to read your explanation of not including games and rush to critizise....utilize the time you have on the system running more important tests....

    /my 2 cents :-))

    and again great job with the article and the site, and I am very impressed with how you handle the BS'ers who talk ablut your integrity...i have and probably never will question this sites validability...dont come here if you just want to complain about it....

    #92, that is a huge understatement. I have been coming here for 7 years, AT has been my start page for the last 6 years... This is 100% due to the totally unbiased and thorough reviews posted here. To compare to some trashy RAG website like the inquirer is totally inacurate. Thats like comparing CNN news to the Inquirer (magazine) LOL

    Great article. You were one of the first to review, too.

    I am looking forward to see AMD's take on dual core. Whether hyperthreading make sense now that you have two real processors.

    In the real world, I am looking for dual core to be use in a home server at a price that will hopefully be cheaper than a dual cpu machine.

    Even if dual core won't make our single threaded application run faster, it may make your machine more responsive. How much crap is running in the background these days: virus checker, spyware blocker, personal firewall, drive indexer and checker. Pretty soon, we'll all need Dual Core just to keep our machine responsive.

    An excellent application for testing would be VMware Workstation. For me, this is by far the most demanding application that I use on a regular basis. For those of you who do not have experience with this software and have a need to stage multicomputer systems but are (like me) hardware limited this is the bomb application. Plus, it makes an great multitasking load.

    I stand corrected Anand. My research indicates your reputation far exceeds that of the Inquirer.
