For each component that can go into a PC, there are usually countless models to choose from, and the CPU scheme of things is no different. For those looking to spend around $250, the options are AMD’s Phenom II X4 955 and Intel’s Core 2 Quad Q9550. AMD is confident that their product delivers a better value, so let’s check to see if that’s the case.
SYSmark 2007 Preview
Synthetic benchmarks have typically been favored for performance testing, but the results they provide can be fairly abstract, and the methods they use to assign their scores can be dubious at times. By contrast, real-world application benchmarks provide performance metrics that apply directly to real-world usage, and we endeavor to apply both in our performance comparisons.
SYSmark 2007 Preview from BAPCo is a special case, because its synthetic scores are derived from tests in real-world applications. However, we still believe that synthetic benchmarking scores are best used to directly compare the performance of one piece of hardware to another, and not for developing an impression of real-world performance expectations. SYSmark is more useful than most synthetic benchmarking programs in our opinion, because its tests emulate tasks that people actually perform, in actual software programs that they are likely to use.
The benchmark is hands-free, using scripts to execute all of the real-world scenarios identically, such as video editing in Sony Vegas and image manipulation in Adobe Photoshop. At the conclusion of the suite of tests, five scores are delivered: an E-learning score, a Video Creation score, a Productivity score, and a 3D Performance score, as well as an aggregated ‘Overall’ score. These scores can still be fairly abstract, and are most useful for direct comparisons between test systems.
A quick note on methodology: SYSmark 2007 requires a clean install of Windows Vista 64-bit to run optimally. Before any testing is conducted, the hard drive is first wiped clean, and then a fresh Windows installation is conducted, then lastly, the necessary hardware drivers are installed. The ‘Three Iterations’ test suite is run, with the ‘Conditioning Run’ setting enabled. Then the results from the three runs are averaged and rounded up or down to the next whole number.
With the top chart so large, it’s hard to compare one CPU to another directly, but the overall score sums things up nicely. Here, the 955 scores 175, whereas the Q9550, in which it competes, scores 185. Not a huge difference, and not one that’s too important. Time for what really matters, real-world testing!
