Gigabyte 6 series motherboards incorporate an Intel approved Intersil PWM controller that is VRD 12 (Voltage Regulator Down) compliant. This means that it offers features that include SerialVID (SVID) which transfers power management information between the processor and voltage regulator controller, allowing more robust and efficient signaling control between the CPU and PWM controller - hence, delivering a more energy efficient platform. Gigabyte's motherboards feature higher capability audio solution with 108 dB signal-to-noise ratio (SNR) playback quality to deliver high-performance, multi-channel HD audio. SNR is a comparison of the amount of signal to the amount of noise such as hiss present in the signal. A higher SNR equals a better audio experience. For example, 108 dB is a high audio specification, as this means the audio signal is 108 dB higher than the level of the noise.
