ASRock unveiled a pair of new motherboards based on Intel's new Pentium J2900 quad-core "Bay Trail" SoC. These include the Q2900-ITX (mini-ITX) and the Q2900M (micro-ATX). Both feature the 10W J2900 chips cooled by a fan-less chunky aluminium heatsink. The J2900 features four cores, nominal clock speeds of 2.40 GHz, with 2.66 GHz Turbo Boost, 2 MB of cache, 688-896 MHz Intel HD Graphics, and a dual-channel DDR3 memory controller. The Q2900-ITX offers two DDR3 SO-DIMM slots, a single PCI-Express 2.0 x1, a miniPCIe 2.0, two-each of SATA 6 Gb/s and SATA 3 Gb/s ports, four USB 3.0 ports, display outputs that include DVI, D-Sub, and HDMI; 8-channel HD audio, and gigabit Ethernet. The Q2900M, on the other hand, features much of the same features, except full-size DIMM slots, an additional PCI-Express 2.0 x16 and PCIe 2.0 x1 slots; and 6-channel HD audio instead of 8-channel.
