AMD last month launched five processor models, three Athlon II’s and two Phenom II’s, and we’re taking a look at one of each. The Phenom II is a 3.20GHz dual-core, and a Black Edition dual-core at that, while the Athlon II is the ultra-affordable 2.9GHz quad-core. Let’s see how both stack up to the rest of AMD’s line-up, and the competition.

Page 2 – Test System & Methodology

At Techgage, we strive to make sure our results are as accurate as possible. Our testing is rigorous and time-consuming, but we feel the effort is worth it. In an attempt to leave no question unanswered, this page contains not only our testbed specifications, but also a fully-detailed look at how we conduct our testing. For an exhaustive look at our methodologies, even down to the Windows Vista installation, please refer to this article.

Test Machine

The below table lists our testing machine’s hardware, which remains unchanged throughout all GPU testing, minus the graphics card. Each card used for comparison is also listed here, along with the driver version used. Each one of the URLs in this table can be clicked to view the respective review of that product, or if a review doesn’t exist, it will bring you to the product on the manufacturer’s website.

(Sim) represents models that were tested using a faster, but under-clocked processor. For example, for the Q9550, we used the QX9770, since the specs are identical all-around, except for the clock speeds. Those were adjusted appropriately, effectively giving us a Q9550 to test with.

When preparing our testbeds for any type of performance testing, we follow these guidelines:

    General Guidelines

  • No power-saving options are enabled in the motherboard’s BIOS.
  • Internet is disabled.
  • No Virus Scanner or Firewall is installed.
  • The OS is kept clean; no scrap files are left in between runs.
  • Hard drives affected are defragged with PerfectDisk 10 prior to a fresh benchmarking run.
  • Machine has proper airflow and the room temperature is 80°F (27°C) or less.
    Windows Vista Optimizations

  • User Account Control (UAC) and screen saver are disabled.
  • Windows Defender, Firewall, Security Center, Search, Sidebar and Updates are disabled.

To aide with the goal of keeping accurate and repeatable results, we alter certain services in Windows Vista from starting up at boot. This is due to the fact that these services have the tendency to start up in the background without notice, potentially causing slightly inaccurate results. Disabling “Windows Search” turns off the OS’ indexing which can at times utilize the hard drive and memory more than we’d like.

Application Benchmarks

To help test out the real performance benefits of a given processor, we run a large collection of both real-world and synthetic benchmarks, including 3ds Max, Adobe Lightroom, TMPGEnc Xpress, Sandra 2009 and many more.

Our ultimate goal is always to find out which processor excels in a given scenario and why. Running all of the applications in our carefully-chosen suite can help better give us answers to those questions. Aside from application data, we also run two common games to see how performance scales there, including Call of Duty 4 and Half-Life 2: Episode Two.

Game Benchmarks

In an attempt to offer “real-world” results, we do not utilize timedemos in any of our reviews. Each game in our test suite is benchmarked manually, with the minimum and average frames-per-second (FPS) captured with the help of FRAPS 2.9.5.

To deliver the best overall results, each title we use is exhaustively explored in order to find the best possible level in terms of intensiveness and replayability. Once a level is chosen, we play through repeatedly to find the best possible route and then in our official benchmarking, we stick to that route as close as possible. Since we are not robots and the game can throw in minor twists with each run, no run can be identical to the pixel.

Each game and setting combination is tested twice, and if there is a discrepancy between the initial results, the testing is repeated until we see results we are confident with.

The two games we currently use for our motherboard reviews are listed below, with direct screenshots of the game’s setting screens and explanations of why we chose what we did.
