Abits BG7 with i845G and DDR333 in the test: Intel's i845G outside of the specifications

Audio Winbench 99

  • The code number '99' may indicate an outdated benchmark. But the program is still doing its job today. The Audio Winbench measures the load on the main processor for various sound qualities. The result is a guarantee for the quality of the onboard codec. These often do their job rather badly and are an imposition for any processor, especially on slower PCs.

As a well-known representative of its kind, the Realtek ALC650 codec was once again used in the BG7, which had been used in the past with low CPU usage and good sound quality. And at least as far as the CPU load is concerned, this also applies to the Abit BG7. At 1.67 percent, the CPU utilization is in the normal range for this codec.

Audio Analyzer

  • The audio analyzer tests sound chips for their quality. The line-out and line-in of the sound card are connected via a loop-through cable so that the 'audio analyzer' can compare the transmitted and re-recorded signal directly with a reference value.

And this sound quality is convincing again. Only the 'stereo crosstalk' is rated slightly worse by the audio analyzer on the BG7 than on the other four boards with Realtek ALC650 codec, so the final rating (overall) is slightly worse.
