Two onboard controllers and three PCI Express x1 slots consume only five of the ICH10R southbridge’s six lanes, providing full bandwidth to all devices.
PS/2 keyboard and mouse ports and analog audio jacks are the P45TS-R’s only links to the distant past, with digital audio, six USB 2.0, eSATA, IEEE-1394 FireWire, and Gigabit Network ports dominating remaining space. The eSATA connection isn’t actually a port however, as it’s simply a pass-through connector for which a cable must be run internally to on of the Intel ICH10R’s internal ports.
The Realtek RTL8111C gets optimal performance from its PCI Express x1 interface, which provides the controller with more than twice the needed bandwidth for peak bi-directional traffic.
JMicron’s JMB368 also gets over twice the needed bandwidth via PCI Express x1. Its single Ultra ATA-133 connector is actually slow enough to use a PCI interface, but the use of PCI Express eases cable routing while freeing up a little board space.
ASRock uses PCI for its chosen IEEE-1394 FireWire controller, but eliminates complicated trace routing by putting it next to the southbridge. The VT6308S provides two 400 megabit ports, with combined traffic never exceeding the one Gb PCI standard.
Like ever recent ASRock motherboard we’ve tested, the ALC890B provides eight-channel (7.1 surround) output with a claimed 110db signal-to-noise ratio.
