Integrated Sound
We have already said a lot of good things about the sound solution implemented on DFI LanParty UT RDX200 CF-DR mainboard. But will our impressions be proven by the results of the practical tests? Let?s find out!
Frequency response (from 40 Hz to 15 kHz), dB: | +0.25, -0.31 | Good |
Noise level, dB (A): | -88.6 | Good |
Dynamic range, dB (A): | 88.0 | Good |
THD, %: | 0.0080 | Very good |
IMD, %: | 0.019 | Very good |
Stereo crosstalk, dB: | -85.0 | Very good |
IMD at 10 kHz, %: | 0.014 | Very good |
General performance: Good
Nothing surprising: our tests indicate that we are dealing with very high-quality integrated sound. So, the sound solution on ATI Radeon Xpress 200 CrossFire based mainboards is a way better than what NVIDIA nForce4 has to offer. And this is not just theory.
Moreover, the integrated sound solution of our DFI LanParty UT RDX200 CF-DR can boast not only high quality analog implementation. We have also noticed that the CPU utilization remained very low throughout the test. Here are the results we obtained in the sound test from the 3DMark03 suite:
As we see, ATI SB450 and Realtek ALC882 load the CPU much less than NVIDIA nForce4 Ultra with the typical Realtek ALC850 codec.
