Dual Core Stress Test: AMD vs. Intel

The THG Lab Logbook: AMD Almost 3 Days, Intel 2 Days Online

Friday, June 10, 2005: Both systems have been running without any problems so far, AMD since June 7, 8 pm, Intel since June 8, 3 pm. Many of our readers asked us to publish the test protocol - so here you go. In addition to that, we also show the results reached so far before we reset the statistics. This was due to the SLI instability on the nForce4 Intel platform. Find it on the last page of this article. Just a quick reminder - we had to replace the SLI configuration by a single graphics solution.

We also like to thank those readers who discovered a questionable error message in our Intel statistics showing "network not connected" whereas it did not show up on the AMD platform. Unfortunately, our stat tool was still connected to a logfile of the previous motherboard. The new one was sending network data to a file with a different name - sorry for that. So don't worry, we didn't loose any data and everything is alright now. By short inspection we didn't find any irregularities in this file by the way. All important data logs such as temperature, fan speed and memory usage have been displayed correctly.
