AMD System

The AMD system uses two 2.0GHz Barcelona (Opteron 2350) or two 3.0GHz Santa Rosa (Opteron 2222) processors mounted on a Tyan S3992 main board, with 8x1GB of DDR2-667 OEM memory. Internal cooling consists of five 3.5" fans and two CPU fans. Internal storage is provided by one WD1600YD hard drive, which is where the OS is installed.

Intel System

The Intel system uses two 3.0GHz Harpertown (Xeon E5472) or two 3.0GHz Clovertown (Xeon X5365) processors mounted on a Supermicro X7DWN+ main board, with 4x2GB 800MHz OEM FB-DIMMs. Internal cooling consists of three 3.5" fans. Internal storage once again comes from one WD1600YD hard drive with the OS installed.

    Barcelona is about as fast as Harpertown in AS3AP. OK.

    In your article you write:
    "The Scalable Hardware benchmark measures relational database systems. This benchmark is a subset of the AS3AP benchmark and tests the following: ..."

    Now you choose a subset of this test in which Harpertown is much faster. Obviously AS3AP consist of several substest and you could as well choose one where Barcelona is much faster. But whats the use of this? You tested all subtest together with your AS3AP-Test.

    Its the same as testing a game and both CPUs having the same score. Then you choose a subtest(e.g. KI only) where Harpertown is faster and conclude its faster overall.

    So what did I miss here? From what I read Barcelona is as fast in AS3AP as Harpi(and should be faster in some subtest and slower in others) while you conclude:

    "Intel has made some successful changes to the quad-core Xeon that have helped it achieve as much as a 56% lead in performance over the 2.0GHz Barcelona part."

    I dont understand this.

    Did anyone here notice the huge metal bar across the FB-DIMM slots? It must be for more FB-Dimm cooling. Without looking at the server first hand, you can't tell how the metal bar is attached to the memory.

    My question is this: where can you buy the bar if you were to build a server class PC yourself? And can someone tell me the mounting mechanism.

    Update: For those that are looking for more details and wondering why certain other chips aren't included, at the time testing was conducted we did not have any of the faster 2.5GHz Barcelona chips (or the slower Harpertowns). That situation has been remedied in terms of AMD's CPUs, and we will have some update articles looking at how the faster Barcelona compares with other processors. Stay tuned...


    One other piece of data is missing from the article, and it's looking like it might be important...
    Kris Kubicki wrote in his blog
    "The 2.0 GHz samples we saw on Monday were of AMD's B1 stepping of Barcelona. But these processors are not the ones we'll see on Newegg's shelves"
    "Production Barcelona samples come with the BA revision designator"
    "One AMD developer, who wished to remain anonymous for non-disclosure purposes, stated, "B1 versus BA should be at least a 5%, if not more, gain in stream, integer and FPU performance.""
    "An AMD engineer, when confronted with the claim, stated that 5% gains when moving from B1 to BA processors "seem conservative.""


    Given that, when you guys do the update, could you let us know which stepping it is that you're using? It appears that it may make a significant difference...

    Remember: 5% performance gains in synthetic benchmarks that stress specific aspects of a CPU don't mean 5% real-world gains.

    I agree...but that's exacly why I am looking forward to some real-world benches on the production steppings. We still have no idea how shipping Barcelonas perform yet.
  • Viditor - Thursday, September 20, 2007 - link

    Further on that...supposedly the reason for the better performance is fixing some major errata. It's quite possible that the performance boost is across the board and not just in synthetic benches.

    You run two benchmarks, you run closed software, you run software that might be optimized for the market leader's processors only, you run software that can't be optimized for the new architecture, you don't benchmark any alpha software that uses rapid virtualization.

    Maybe we have some benchmark numbers but the real performance of Barcelona is still speculation.

    AMD is always the underdog. They need superior product to gain market share. That was the case of Athlon vs Netburst. If Barcelona is just competitive, it is not good enough for them to regain the crown. They will stay as underdog.

    From what I understand, these new (Harpertown) Xeons will not be released until November (12th?). Yet the article makes no mention of it, and by reading it, you would assume you can buy them right now.

    Or have I understood something wrong?

    Intel systems are power mongers...generate enough heat to replace a room heater.Check out any dual socket systems they are using all kinds of cooling to cool the FB-DIMMs those are the worst part in intel builds.
