Where the former eliminates noise interference, the latter unfortunately still has that issue. When compared to the ASRock Z270 Extreme 4’s Purity Sound4 audio codec, the ALC890 chipset is seen as inferior and outdated. The Z370 Killer SLI/AC has a Realtek ALC890 chipset with 7.1 HD audio support. The ports that are present include five audio jacks with a S/PDIF Output, a dual connecter PS/2 port for mouse and keyboard, an Intel Gigabit LAN port, four USB 3.0 ports, support for USB Type C, and a DVI and HDMI port.
