Introduction and Setup Impressions

Over the last couple of years, the ultra-compact form factor (UCFF) has emerged as one of the bright spots in the troubled PC market. Intel kickstarted the category with their Sandy Bridge NUC kits in early 2013. Recognizing the popularity of this segment, other vendors also began to promote similar products. GIGABYTE targets this market segment with an extensive lineup of products under the BRIX brand. We recently looked at the high-end Haswell BRIX, the GB-BXi7-4500. The focus of this review is on the opposite side of the spectrum - they Bay Trail-D Celeron J1900-based GB-BXBT-1900. As a note, due to GIGABYTE's regional marketing policies, this model is currently not being sold in the North American market, but targets price conscious buyers everywhere else.

Similar to other BRIX units, the BXBT-1900 comes barebones. An important point to note is that, unlike the higher-end BRIX units, the BXBT-1900 doesn't support mSATA drives. The support for 2.5" drives makes the z-height a bit more than the BRIX s (pure mSATA) models that we have looked at before. The dimensions (56.1 mm x 107.6 mm x 114.4 mm) otherwise conform to the smallest possible BRIX units (29.9 mm x 107.6 mm x 114.4 mm). Another point of difference is the presence of only one SO-DIMM DDR3L slot rated for operation at 1333 MHz (compared to the dual 1600 MHz-capable slots in the Haswell-based units). We configured the review unit to end up with the following components:

GIGABYTE GB-BXBT-1900 Specifications

Operating System

Retail unit is barebones, but we installed Windows 8.1 Pro x64

Pricing (As configured) ~$170 (barebones) + $129 (DRAM + 2.5" SSD)

The BXBT-1900 kit doesn't come with any pre-installed OS, but does come with a driver CD. In the higher-end kits, GIGABYTE has moved to USB keys for the drivers. In any case, we ended up installing the latest drivers downloaded off GIGABYTE's product support page. In addition to the main unit, the other components of the package include a 30 W (12V @ 2.5A) adapter, a US power cord, a VESA mount (along with the necessary screws), a driver CD and a quick-start guide.

The gallery below takes us around the hardware in the unit.

In order to complete our build, we opted for a 2.5" Samsung SSD 840 EVO (with the read performance bug recently fixed) and a single Crucial CT51264BF160B (Micron 8KTF51264HZ-1G6J1) 4 GB SO-DIMM.

In the table below, we have an overview of the various systems that we are comparing the BXBT-1900 against. Note that they may not belong to the same market segment. The relevant configuration details of the machines are provided so that readers have an understanding of why some benchmark numbers are skewed for or against the BXBT-1900 when we come to those sections.

    Size doesn't matter.

    This review is too scatterbrained. The reviewer says "Intel HD Graphics" but doesn't specify which version; "not being sold in the North American market", yet also says: "a US power cord".
    Wut? Anand is seeing his old web site go down the drain.
  • nickb64 - Sunday, October 26, 2014 - link

    "Intel HD Graphics" is exactly what Intel calls it. No number or anything.
  • sjprg2 - Saturday, October 25, 2014 - link

    Why would any company make the SSD controller a SATA 2 instead of a SATA 3?
    also a 5 GHZ wireless would make this a great remote backup.
  • abufrejoval - Sunday, October 26, 2014 - link

    You'd need to ask Intel that: This is a system on chip or SoC and SATA comes off that chip.
    Intel might say that SATA 2 saves power and that might even be true. More likely they are just afraid they'll sell less mainline CPUs and chipsets if these SoC were too powerful.

    In practice I find the difference only important on jobs I wouldn't want to do on this system anyway.

    The wireless card isn't soldered on: In theory you could get another card that supports 5GHz for minimal bucks.

    No kabini result? i want to see this cheap amd chip compared with this expensive intel box. Really, it should be there.

    As much as I love the BRIX in terms of form factor, case look and sturdyness etc. I could never quite fathom their choice of notebook type active cooling systems, especially since they are full metal cases (top cover also has metal under a cover which is plastic for "looks").

    Well of course these notebook fans are cheap, being mass produced in incredible numbers, but they get far too noisy under load. I tried a 15Watt Haswell BRIX and had to return it heartbroken: I loved the little box, but I couldn't stand the constant fan speed changes, which gave me far too much feedback on just how hard the CPU was working.

    I run the GIGABYTE GA-J1900N-D3V which is completely passive and I thus know it's possible to design a passive box in the BRIX form factor.

    And if by all means they need to share a fan design with the bigger boxes, why can't they put a bigger one in, say something Noctua, which never more than whispers?

    Although one of the biggest attractions of these BayTrails is that you can design systems all passive which just run forever somewhere in a corner completely silent and sealed with no chance of choking on dust.

    BTW: I'm glad you finally measured clock speeds and power consumption! Yes, the J1900 (and the J1800 likewise) *never* run at anything but turbo clocks under load. The "official" clock rates are simply bogus numbers, perhaps designed to keep people away from these SoCs or to "manage performance expectations": With Intel everything is possible.

    Idle power clearly speaks for the BRIX and the integrated power supply, which is probably a far better match than the Pico-PSU and external 12V brick that I am using on the GIGABYTE GA-J1900N-D3V, which gives me 10/28 Watts on idle/full load.

    BTW: I've never noticed that a single DRAM channel limited the BayTrail SoCs in any way: Most likely that's because they only ever have a single channel DRAM interface anyway.

    And for Core 2 comparisons: I didn't run too many benchmarks but the J1900 at 2.41 GHz matched 80% of my QX9100 @ 2.40 GHz on all pure CPU benchmarks I tried (POVray and Cinebench R15 raytracing) at 28 vs. 65 Watts.

    If they managed to make this completely passive and silent this would be the perfect desktop. It runs pretty much every x86 OS right out the box with decent but not awe inspiring performance at 1920x1200 or below. Video at least on Windows with is great with all that hardware support from an Intel HD VPU including QuickSync and 3D is limited only by speed not by feature availability, which often enough is all you want (e.g. Compiz 3D effects on Linux).

    Can't expect gaming performance from a system costing less and using less power than an entry level grapics card.

    @Ganesh T S: did you get a chance to test this with WMC? Specifically, high bitrate CableCard streams where you change the resolution from windowed to fullscreen or portrait/landscape. My Asus T100 wasn't able to handle this well at all so I ultimately stopped using it as a WMC device and finally sold it. It would hang for up to 60 minutes changing context/resolution and I could never figure out if it was the slow eMMC storage, the GPU, single-channel RAM or what.

    I wanted to get a Celeron NUC for an HTPC but ultimately this scared me off and I went with the i3 NUC instead, which cost more than 2x as much.
  • zlandar - Tuesday, October 28, 2014 - link

    I know Celeron is just a name but every time I've used Intel chips below i3 the performance sucks.

    Rather pay the price premium for an i3 than risk being unhappy with a stuttering NUC.

    The comparison with other NUCs seem way off as you mostly compared it against i5/i7 systems and no i3. It's like stacking a HTPC video card against a mid to high range gaming video card.
