    OfficeBench 2001

    It should be noted that OfficeBench2001 runs only in MS Windows 2000 - it does not run on any DOS based MS operating system. This benchmark has some similarities with SYSmark2001, at least, insofar as they both run concurrent workloads to better simulate reality, rather than a linear script where one program is run after another. The benchmark consists of a relatively short script, which uses programs such as Internet Explorer, Power Point, and other programs to do content creation, such as creating complex tables, etc.

    The baseline load simply runs the script. This script can be adjusted so as to include section delays, which help to simulate pauses that a user would use, such as switching to a different application, pausing, scrolling down, pausing, etc. However, very intensively used computers may have other programs running concurrently, such as acting as an exchange server, database accesses, and streaming video. The load-levels represent a differing number of instances of the programs running at once. For example, load-level one has one instance of the aforementioned tasks running while the base script runs, while a load-level of two has two instances of each of the task while the base script runs, etc.

    The greater the number of tasks running at once, the longer it will take to complete the base-script (which is what the benchmark times), in part due to the increased number of calculations required because more instances of the various programs running, and also in part due to the context switches involved with the CPU rotating through the various active threads. Another impact is due to L1, L2, and main memory bus contention due to the great number of loads and the types of applications being run. See below to see the results from the varying load-levels.

    OfficeBench 2001 is a new benchmark that was recently introduced to our world through a Pentium 4 1.8GHz review on AnandTech. After running the test ourselves, we were a bit perplexed. After checking AnandTech's scores as a comparison, we noticed that our times were significantly lower(better) than Anand's, especially at load level 2. For example, on load level 2, Anand finished in 86.13 seconds with the 1.8GHz Pentium 4, we finished in 60.36 seconds with a 1.7GHz Pentium 4. Both of our systems are configured almost identically, although Anand's system had a different motherboard, but our scores were much better with the Athlon as well.

    After realizing this, I got on the phone with Randall Kennedy, creator of OfficeBench, to see if he had any ideas. We couldn't come up with anything, so I e-mailed Anand to see if how he tested or if he had an idea why the results were so off, but we never recieved a response.

    We won't be able to refer you to any other sites for other CPU's benchmarks because we are unsure as to whether or not Anands scores are accurate (as we talked to Randall, and he too was stumped), and no other sites have use OfficeBench yet.

    Baseline Load Level


    Lower is better

    With no load we can see here that the Pentium 4 completed the test 25% faster than the Athlon, but considering that the Pentium 4 is clocked 35% faster and has faster memory, is that really a big feat? This is where we really wish we could have had more CPU's in the lab to compare with.

    Load Level 1


    Lower is better

    We notice here that the Athlon starts to move towards the Pentium 4, and looks to be handling the multitasking a bit better. Lets see if this trend continues with the load level turned up another notch.

    Load Level 2


    Lower is better

    Looks like that trend didn't continue as the Pentium 4 takes a huge leap back around 32% faster. This is where P4's massive memory bandwidth comes into play. When load levels are this high, the processors speed gets somewhat taken out of the picture, and performance boils down to which platform can get the data to the CPU the fastest.

    Load Level 3


    Lower is better

    The performance gap seems to stay pretty stable here, but with load level 3, it's testing a load that none of our systems would probably incur. How many of you will be running 3 exchange servers, accessing 3 databases, streaming 3 videos, and using Microsoft Office at once? Thought so :).
