Benchmark Configuration

We used the MySQL version (4.0.18) that came with the SUSE SLES9 CD's and Mac OS X Tiger 10.4.1, which was certified to work on our OS. Our YDL Linux reported: "Linux version 2.6.10-1.ydl.1g5-smp (gcc version 3.3.3 (Yellow Dog Linux 3.3.3-16.ydl.7))"

Shared
MySQL 4.0.18, 32 en 64 bit, MyISAM engine
Gcc 3.3.3 and 4.0

    Sorry couldn't resist :-). (for the rest of the world, pannekoek is dutch for Pancake)

    Desktop performance is ok, as desktop apps are similar to the workstation apps we tested in the first article. Those apps spend from 5-20% in the OS, while server apps spend up to 80% of their time in the OS!

    However, I should point out that we tested Mac OS X SERVER, so it is a problem for the Xserves.
  • Pannenkoek - Friday, September 2, 2005 - link

    I stand corrected then. However, my reasoning still applies, it's just that Apple relies even more on its brand than on technology to sell server systems apparently. Who runs Mac OS servers anyway, it's an oxymoron. ;-)

    P.S. Do not mock my nick, it served well in beating godlike UT bots, and should be honoured as much as Loque.

    "Apple told us that the problem lies in the Apachebench (the client side), which stalls from time to time and thus, generates too low of a load on the (Apache) server."

    How does this explanation make any sense? Linux obviously doesn't have a problem with these "stalls".
  • JohanAnandtech - Friday, September 2, 2005 - link

    What follows is not what Apple said, but my interpretation...

    They are probably pointing out that the version for Mac OS X has a Mac OS X specific bug. Of course, who is to blame? I am sceptical like you.

    Page 4 :

    We used the following on the Opteron based PCs:

    Gcc -O2 -mcpu=G5 flops.c -o flops

    And, on the G5 machines, we used:

    Gcc -O2 -march=k8 flops.c -o flops

    I think it's the other way around.
  • Houdani - Thursday, September 1, 2005 - link

    Aye, was gonna point that out also.

    In addition, on page 3 should you list the Yellow Dog Linux along with OSX in the Software section for the Apple PowerMac G5?
  • Shinei - Thursday, September 1, 2005 - link

    My question is, would the memory latencies be so high for the 970FX if high-end RAM was used for the Linux tests (like, say, some TCCD or BH-5 at 2-2-2-5), instead of the standard 3-3-3-8 SPD that ships with the G5 system? Or is there some limitation to the G5 motherboard that prevents posting with performance RAM as a way for Apple to ensure that only certain, accepted DIMMs are used with their computers?
    Anyway, these results are very telling about what the OSX86 Macs are going to perform like--that is to say, ~25% slower than the equivalent Windows/Linux boxes running the same hardware...

    That doesn't matter since they are testing workstations, Irwindale and Opteron is also using CAS3 RAM. No workstations/servers use 2-2-2-5 RAM.


    The poor scores of OS X compared to Linux makes sense. G5 was rumored to be fast in speccpu benchmarks but came out to be slower. Must be that rumor systems were benched with Linux and the production was benched with OSX.

    I am impressed with OS X's features though.
  • Jedi2155 - Thursday, September 1, 2005 - link

    The G5 motherboard has the limitations due to Apple's way to insure you only buy certified ram. The SPD settings must be perfect.

    I am humbled by the sheer expertise of Johan. Amazing work, Johan!

    This makes me even more curious about Intel's contribution to the next generation of Macs. How will they compare to the best G5s?
