Intel's Haswell architecture is anticipated to arrive in Q2 2013 and FUD Zilla reports the Z87 will be the top chipset for this new CPU. Haswell is expected to last through 2014 but will introduce the new LGA1150 socket, making it incompatible with current motherboards.
The Z87 should be ready to meet the launch of Haswell and will be used by flagship motherboards. The chipset can support PCIe 1x16, 2x8 or 1x8 + 2x4, and will introduce Rapid Storage Technology 12 with fast sync streaming, Lake Tiny tech, UEFI fast boot support, SATA 6Gbps, RAID 0/1/5/10, rapid recovery technology, smart responsive technology, and TRIM on RAID 0 SSD configurations.
It doesn't come with small business advantage technology support, Intel has the H87 for small business users, but it does include 14 USBs of which 4 are USB 3.0 ports. Of course, 6 SATA 6Gb/s, eight PCI express 2.0 5GT/s. two DIMM modules per channel are supported and the new chipset should also be good for overclocking.
Let's not forget the Gigabit Ethernet MAC.
Integrated voltage regulations are included on the chipset and it features USB 3.0 support and integrated triple display support via Haswell, with HDMI, DVI, DP, eDP and VGA output support.
