Mini-ITX SBC packs lots of I/O, runs Linux on Haswell

Aug 14, 2013 — by Rick Lehrbaum 4,566 views

Win Enterprises announced a Mini-ITX single board computer based on Intel’s 4th Generation (Haswell) Core i7, i5, and i3 processors, paired with an Intel QM87 chipset. The compact MB-73320 SBC accommodates up to 16GB of DDR3 SDRAM, offers numerous storage, networking, video, audio, USB, and multi-protocol serial interfaces, and expands with both Mini-PCIe modules and standard PCI Express cards.

Win Enterprises says the MB-73320’s ability to run from a variable 8-32V DC input makes it ideal for use in a wide range of space-constrained, graphics-intensive embedded applications in markets including industrial automation, communications, military, medical, and digital surveillance.

Intel’s Haswell processors have already found a footing on quite a few Mini-ITX designs, including Aaeon’s EMB-QM87A, BCM’s MX87QD and MX81H, DFI’s HM100-QM87 and HD100-H81D, iBase’s MI980, Kontron’s KTQ87/mITX, and Portwell’s WADE-8015, which combine the Haswell part with either an Intel QM87, Q87, or H81 chipset. For its MB-73320, Win Enterprises chose the Q87.

Although the Haswell processors are minted with the same 22nm fab and Tri-Gate 3D technologies as the previous Ivy Bridge Core parts, they deliver around 15 percent higher performance, says Intel. Where the Haswell-based chips really excel, however, is on the graphics side, thanks to new Iris and Iris Pro GPU designs. Claimed graphics performance increases have ranged up to 75 or even 100 percent, depending on the particular application.

Another major Haswell benefit, according to Intel, is a reduction of power consumption by up to 50 percent. For example, a quad-core Core i7 offers 15W TDP power consumption, down from 20W on similar Ivy Bridge processors. The full list of processors, many of which have to yet ship, may be found at Intel 4th Gen product pages for Core i7, as well as Core i5 and Core i3. Three of the i7 and two of the i5 are listed as having embedded support options.
