ASRock Mix And Matches Intel P67 Chipset With S1156

This is a socket LGA1156 motherboard, it supports existing Core i5/Core i7 "Lynnfield", and Core i3/Core i5 "Clarkdale" processors, but is based on the Intel P67 Express chipset. The board gives users access to some advanced features of the P67 chipset, but won't support LGA1155 processors.

So what's in it for you? Well, the P67 PCH embeds a PCI-Express 2.0 hub compared to P55/H55, which pack an older PCI-Express 1.1 hub. This hub is known to heavily bottleneck devices such as USB 3.0 and SATA 6 Gb/s controllers that use only a single PCI-E lane (since PCI-E 1.1 has 250 MB/s per direction bandwidth, compared to 500 MB/s on the PCI-E 2.0). So significant this bottleneck is, that some motherboard designers even used bridge chips that convert the P55's PCI-E 1.1 x4 port to two PCI-E 2.0 x1, for USB 3.0 and SATA 6 Gb/s controllers. The PCI-E x16 slots however, are wired to the processor and are Gen 2. ASRock's board hence gives you two USB 3.0 and two SATA 6 Gb/s with an alleviated bus bottleneck.
