Our recent review of the HP Stream 11 by Brett Howse, featuring a dual core Bay Trail-M, made me wonder about the utility of such a desktop system with Bay Trail-D. Despite testing the J1800N-D2H earlier in the year but not writing a review, I thought it best to polish of the data and see if it still relevant alongside the $200 offerings and worth the potential extra cost for a full build to fill out a motherboard in exchange for the potential extra functionality (2T2R WiFi rather than 1T1R, SATA drives rather than eMMC).

The 10W Celeron J1800 SoC sits at the bottom of Intel's Bay Trail-D range, featuring a dual core with a 2.41 GHz base allowing a turbo mode up to 2.58 GHz with dual channel memory at DDR3-1333.

In terms of competition, AMD's Kabini launch in the middle of the year was a direct competitor to Intel's Bay Trail-D line, offering 25W socketable APUs with better graphics and DDR3-1600 memory, albeit single channel.

AMD also competed on price, offering a motherboard and APU combo in the $65-$110 range, depending on a dual core or quad core configuration. For a comparison point the J1800N-D2H on review today retails for $69. You can read our review of the Kabini APUs here.

Back to the comparison, in terms of on paper performance the HP Stream 11 is a little down in terms of base frequency and DRAM, though does benefit from the mobility aspect, a lower TDP and the stress free 'purchase and use' that you don't get with a self-build system. That being said, a system integrator may be able to provide something very competitive.

GIGABYTE J1800N-D2H Overview

Similarly to our review of the HP Stream 11, at such a low price point for an integrated system, we shouldn't expect much from the J1800N-D2H. Technically the SoC from Intel has a tray price of $72, making the motherboard worth $3 below zero. At a 10W TDP for the SoC, the motherboard combination comes with a passive heatsinks, two SATA 3 Gbps ports, a single USB 3.0 port, a Realtek network and ALC887 audio solution and a PCIe 2.0 x1 for good measure. This last factor limits some upgradeability, especially in the graphics or connectivity department but there is a mini-PCIe for a WiFi card (though this is a separate purchase).

On the layout side of the equation for the motherboard itself, the main power connector and front panel header is on the edge of the motherboard, although the mini-PCIe slot, a fan header and the two SATA ports might be compromised by any large PCIe x1 card being used.

Trying to match the HP Stream 11's price point, including a display and keyboard/mouse is tough, and when the 12 months of Office 365 is factored in, impossible unless you get most of the components from old builds or a number of refurbished parts. The big plus with going through a desktop route would be storage, allowing for a good SSD or two and potential of 8GB DRAM, though as we add in a case/power supply the overall cost might hit $200 before the display/mouse/keyboard is taken into account. I once purchased a 1024x768 VGA display for £15 delivered from eBay last year, so going down that route might be feasible. The laptop is more portable however. But desktop computing on the cheap (with more storage space) is possible with something like the J1800N-D2H.

Visual Inspection

At the sub $100 price point, it can start to get difficult to differentiate products in terms of design. When every penny goes towards functionality or research, especially on a small motherboard, it helps to start on the right foot in terms of layout. GIGABYTE take the 10W J1800 processor and understandably fit it with a passive heatsink, and due to the flexible nature of soldered-on processor-based motherboards, there is no visible x-y dimension restriction.

There are still fan headers on board in order to create a cooler system environment – the CPU fan header is a three pin in white to the left of the heatsink, and the other fan header on board is a four-pin SYS next to the SATA ports at the bottom. The power connectors are found at the top, including a 4-pin CPU power connector. The top of the motherboard also houses an LPT header near the rear panel and a COM header.

As Bay Trail-D is limited to 1333 MHz memory frequency, manufacturers do not have to adhere to XMP profile design, or limit themselves to full-sized DIMM slots. Here GIGABYTE has equipped the J1800N-D2H with two SO-DIMM slots, with the upper flipped around due to the dual channel nature of the SoC. The use of SO-DIMMs also helps keep the overall z-height down.

At the bottom of the motherboard there is a mini-PCIe for users to add in a WiFi module, the two SATA 3 Gbps ports from the SoC, and a PCIe 2.0 x1 slot that is not open ended. Typically these systems are not designed for discrete GPUs, and the chipset limits the GPU to an x1 prompting a severe bottleneck. In before ‘how about a GTX980?’! However, some PCIe 2.0 x1 GPUs do exist if extra functionality is needed.

Audio and network are supplied by Realtek, with the J1800N-D2H using an ALC887 on the former. Given that the SoC is a sizable chunk of the cost of this motherboard (assume ~$35-$40 to the manufacturer, giving a ~$25-$30 motherboard), GIGABYTE does not have a lot of room for additional controllers or upgraded audio.

The rear of the motherboard uses two separate PS/2 ports, a VGA output, a HDMI output, the sole USB 3.0 port from the SoC, four USB 2.0 ports, the gigabit Ethernet port and a trio of audio jacks.

    Good article, but I really would have appreciated if you could compare this CPU to a Celeron 1037u. I have a feeling that with its Ivy Bridge architecture though, that it would probably wipe the floor with this new CPU.

    You'd be right on the dual core version. Compared against the little quad core version, the quad does significantly better. I have to say that I wouldn't consider the dual core for any purchase, but I do have the quad in my htpc. The quad has slower single thread performance, but the total score (geekbench) using all cores matches the 1037u.

    Interesting. Thanks for sharing your experiences. I have to wonder though, when I see a 1037u + motherboard system for sale for like $4 extra dollars, what's Intel's point in releasing this? I suppose eventually when the supply for the 1037u dries up, all we'll have are these Atoms. Hurray - we're paying more for less. :)

    Well, I do agree on some puzzlement as to what purpose the J1800 serves. The J1800 is a 10w part, the J1900 is a 10w part. Geekbench on the J1800 is about 1000 on the single core (matching the J1900) but only 1600 on the multicore score. That is pretty useless and would be somewhat painful to use in real life.

    And - considering that the J1900 scores much higher on the multi-core loads while operating in the same thermal envelope, they can't even say that it's really and issue of power usage in a mobile situation. So, I can see why they would release the J1900 quad, it turns in similar performance metrics as the 1037u while using half the power which is a worthwhile cause.

    The J1800 seems to be a 'broken quad core' part that they're releasing to keep yields high as they sell them to suckers who don't realize how slow they are.

    There would have been a huge market for these if they had the intuition to slot in a couple of extra SATA ports. It would have made for a super cheap 4 bay NAS with extremely low power consumption. Would have easily been the next gen successor to the 1037u for the DIY NAS builders.

    In its current state, it might only appeal to the HTPC builders if it can do transconding on the fly. For those of us who don't need transcoding on the fly, the Raspberry Pi is the perfect solution.

    A secondary market could be those looking for a PC just to surf the net and do light office work but with a score of 1000, even those tasks could be a handful for the J1800. I have a 7 year old Core2Duo laptop with 1083 score and it feels too sluggish for daily use even with an SSD.

    the price link to the dell monitor goes to the amazon search for the viewsonic monitor.

    Okay, so are you using UEFI in Windows 7? This obviously affects POST time. Also Windows 8 POST times with UEFI would be the best case scenario in testing. If I care about POST times, I will be running Windows 8.

    I remember that there have been benches done with Anandtech on Windows 8. Why not across the board?
