In this article we will discuss two integrated sound subsystems. The first is formed by a VIA VT8235 South Bridge and an AC’97 VIA VT1616 codec, and the second one is based on nForce2 MCP-T with the integrated APU SoundStorm and an AC’97 Realtek ALC650 codec. For better comparison we will also include the results for Creative Audigy2 sound card.
Performance: SpectraLAB Tests
The tests we perform with SpectraLAB version 4.32.17 follow the methodology explained in our previous articles. Here, we are comparing the analog parts of the two audio subsystems. It is Realtek ALC650 in ASUS A7N8X, and VIA VT1616 in Soltek KT 400A.
First come Realtek ALC650 spectrograms:
44,100Hz/16bit, 1kHz tone signal
Determining IMD at 44,100Hz/16bit
48,000Hz/16bit, 1kHz tone signal
Determining IMD at 48,000Hz/16bit
