Page 12 - Onboard Sound Frequency Analysis
While Gigabyte did not really advertise the integrated sound on the Z77X-UD3H, the company has a great record of having very good performing audio on their motherboards. Additionally, as discussed on Page 3 of this review, what we have here is not your run-of-the-mill Realtek codec -- it is actually powered by a VIA VT2021 chip. So how does it stack up in our tests? As usual, RightMark Audio Analyzer has the answers, and here is the full report.
