Nobody said they had to use all six : The Biostar TP45 HP “wastes” two of the ICH10 southbridge’s six PCI Express pathways by providing only two PCI Express x1 slots and two onboard PCI Express devices.
The TP45 HP doesn’t have any eSATA ports, but the closest competitor in this round-up doesn’t either. Competitor ASRock fakes it by putting a pass-through connector on the back. Biostar also leaves off any IEEE-1394 FireWire controller, but many buyers will never use that feature anyway. What really says “cheap” about the port panel is the lack of any digital audio outputs, even though the company provided all six analog audio jacks.
JMicron’s JMB368 provides one Ultra ATA header (supporting two drives) using a PCI Express interface. Ultra ATA doesn’t really require PCI-E speeds, but the wiring is simpler than PCI and the motherboard had lanes to spare.
PCI Express provides twice the needed bandwidth to Realtek’s RTL8111C Gigabit Ethernet controller for optimal performance.
Rated at 97db signal-to-noise ratio, Realtek’s ALC888 provides the TP45 HP motherboard with eight main channels (7.1 surround) and separate stereo headphone channels.
