Not ready to let Gigabyte have all the fun, ASRock has announced two new Mini ITX motherboards of its own that come pre-loaded with quad core Intel Gemini Lake processors cooled using fanless heatsinks. The ASRock J4105-ITX and J4105B-ITX measure 6.7" x 6.7" and sport a "sapphire black" PCB constructed of a high-density glass fabric that is allegedly more resistant to humidity and helps to prevent electrical shorts. The boards use all solid capacitors and have voltage spike protections for board components. The J4105-ITX may be of more interest to home users while the J4105B-ITX variant is aimed at industrial and commercial setups since it downgrades the audio outputs but adds more USB 3.1 Gen 1 ports and adds legacy connections for serial (COM), parallel (Printer port), and D-Sub outputs to the rear I/O.
The new Gemini Lake motherboards have a soldered-on Gemini Lake processor cooled by a black heatsink in the top left corner. Two DDR4 SO-DIMM slots sit to the right and beneath the processor (up to 8GB 2400 MHz). The J4105-ITX has a Key E M.2 slot for 802.11ac Wi-Fi + Bluetooth modules, a single PCI-E 2.0 x1 slot, four SATA 6.0 Gbps ports for storage, and headers for a CPU fan, one chassis fan, one USB 3.1 Gen 1, and two USB 2.0 headers (3 ports max). The four SATA ports are comprised of two from the Intel chip and two from an ASMedia ASM1061 chip. On the other hand, the J4105B-ITX does not have a M.2 slot, has a physical PCI-E 2.0 x16 slot (electrically x2), and only two SATA 6.0 Gbps ports. Both boards appear to use the same networking chipset for Gigabit Ethernet with the Realtek RTL8111H. Audio chipsets are a bit different with the J4105-ITX using the Realtek ALC892 and the J4105B-ITX using a slightly cut down Realtek ALC887 chipset.
Rear I/O is as follows:
|2 x PS/2||1 x PS/2|
|1 x D-Sub (VGA)||1 x D-Sub|
|1 x DVI-D||1 x COM|
|1 x HDMI||1 x Printer Port|
|2 x USB 3.1 (5Gbps)||3 x USB 3.1 (5Gbps)|
|2 x USB 2.0||1 x USB 2.0|
|1 x RJ45 (Gigabit Ethernet)||1 x RJ45 (Gigabit Ethernet)|
|6 x Audio (5 x 3.5mm + 1 x S/PDIF||3 x Audio (3 x 3.5mm)|
The Gemini Lake processor used is the Intel Celeron J4105 which is a quad core part (no Hyperthreading) with Intel UHD 600 graphics, 4MB cache, and clockspeeds from a base of 1.5 GHz to a maximum turbo of 2.5 GHz. The UHD 600 GPU reportedly has 12 EUs (execution units) and a max frequency of 750 MHz and supports 4K60 video output, multiple displays, and hardware acceleration of HVEC H.265 10-bit (and 8-bit), H.264 AVC, VP8, VP9 8 and 10-bit video codecs.
This new processor is based on the Goldmont+ architecture which is a bit more efficient and features higher clocks than Apollo Lake along with more L2 cache. You won't be gaming on these things (at least not locally; you should look for APUs or the Intel+Vega Kaby Lake-G CPU for that in this SFF space), but if you need small and silent low power PC for a streaming box, or office work this might fit the bill. I think the biggest market for these particular boards will be small businesses, kiosks, signage, and industrial control and monitoring systems though as they may be a bit too bare bones for enthusiasts to tinker with or home users to get the most out of them (e.g. only one GbE port, 8GB of RAM max, and somewhat limited USB 3.1 ports).
ASRock has not yet announced pricing or availability.
What are your thoughts on these low power SFF boards?
