Manufactured by Intel SoC family of Bay Trail-T found their way into many large plates manufacturers including Acer, Asus, HP, Dell, Lenovo and Toshiba. This generation solutions is significantly different from its predecessors, and provides significantly better performance.Processing undergone almost all key system components including computing cores, the memory controller and graphics controller. In addition to tablets, micro-Silvermont met us in miniPK and network drives . These products have not only higher productivity, but also the associated energy consumption and cost.
The company Foxconn, in the arsenal which has a lot of compact systems, decided to see what happens if we use the «flatbed» version of the platform for microcomputer. From a technical point of view, its Ultra Nano PC can be regarded as devoid of the screen and battery plate.
This device is based on the model of SoC Atom Z3735F and executed in a very compact format, we met previously when considering usually based on Android media players and computers .However, Ultra Nano PC and able to work under the control of Windows, which significantly changes its positioning and possible usage scenarios.
Computer testing was provided as a sample, so that the exact configuration to say anything hard.At least for the power supply is required. In this case, use a variant with USB-output and parameters 5 2 A, connected to the computer via a standard cable and port Micro-USB. Most likely, complete will also be present to monitor cable, because the device has a relatively rare Mini-HDMI.
The enclosure is made of plastic. Top cover in our sample — glossy black, and the rest — matte white. Most likely, consumers will be offered other color options or even removable cover included.
Overall dimensions of the computer — 126 × 126 mm, the thickness is about 14 mm, weight does not exceed 150 g body Relies on legs with rubber inserts a height of 1.5 mm. Unfortunately, there is no full-time options to set the monitor is not provided, although the emergence of commercially available special attachment is possible. Because of the light weight and the use of a relatively thick device video on the table is not very stable.
On the underside of the housing openings are provided passive ventilation, as well as present a signature to all ports, which is very convenient.
On the front side is the power button, and next to it — the blue light. When you turn on the computer will have to hold his hand. On the right side toward the front port has a single USB. The left side is empty.
All other ports and connectors are installed at the rear. Here are the power input port Mini-HDMI, card slot microSDHC, two USB ports and output for headsets. Next to the Micro-USB can be seen another hole, but to deal with his appointment failed.
The manufacturer chose the option of the device powered by a standard port Micro-USB. On the one hand it can be regarded as a convenient as a power supply option is quite common today, and there is no need for frequent connect the terminal will not adversely affect its longevity. On the other hand, provided the current in the two amps leads to the fact that this computer can not work without an external power supply, many external hard drives. The audit showed that the computer under high load in synthetic tests is really capable to consume at least 2 A.
Installing the Mini-HDMI connector instead of the usual full-length may also be considered a compromise between compactness and the prevalence of such cables. Given the desire, in our view, could be put and standard connector.
The memory card slot is useful to expand the scope of internal storage. It is equipped with a latch and the card is completely hidden in it, so you can use it constantly.
All computers have USB ports version 2.0. Rear connectors are spaced widely enough, so that problems with the connection of large devices should not be.
Analog audio port 3.5mm likely supports not only headphones and microphone. However, we could not find a compatible headset model.
Overall, in terms of design and ease of use, the device makes a good impression. It is significantly less than previously tested micro-enabled Windows.
The most controversial decision is to recognize the use of gloss on the top cover. Established the possibility of mounting the monitor could be useful to many users.
The computer is based on SoC Intel Atom Z3735F, which has SDP 2,2 W and has been designed for tablets and smartphones. The chip uses four cores with support for 64-bit computing and relevant instruction sets. Their nominal clock speed of 1.33 GHz, Burst Mode, they can be overclocked to 1.83 GHz. Under no load frequency can be reduced to 500 MHz.
It is worth noting that the manufacturer has as many as four models with digital chip labeled «3735» different alphabetic suffixes. In this case, it is of some importance. Seniority should probably arrange them in the order «D», «E», «F» and «G». Options «E» and «G» only support 32-bit memory interface, and its maximum capacity is 1 GB. In models «D» and «E» can use the controller USB 3.0, support video decoding 4K, and the screen resolution may exceed the Full HD.In any case, all the parameters are determined by a particular implementation or tablet computer.
Maximum supported chip installed RAM standard DDR3L-1333 is 2 GB. That’s how much is present in the computer.
Graphics Controller Intel HD Graphics has a stated maximum frequency of 311 MHz and the possibility of increasing it to 646 MHz. The controller has support for DirectX 11 and OGL 3.2, equipped with hardware decoding blocks of video formats H.264, MPEG2, MVC, VC-1, WMV9 and VP8.
From the video output is present only Mini-HDMI version 1.4, which can provide work with mode monitor up to 1920 × 1080 @ 60 Hz inclusive. Also declared support for stereoscopic display, but it does not apply to video decoding. Given the relatively weak graphics controller, this option probably will not be in demand.
Sound can be output via HDMI or analog stereo. The platform is equipped with a built-in audio controller, which is used in conjunction with I 2 S-codec Realtek. With support for multi-channel digital audio output situation is complicated. The Windows operating system when the device is connected via the receiver shows the properties of HDMI-out opportunity to work with DD, DD + and DTS, and even allows you to test the functionality of a multi-channel acoustic mode LPCM.However, attempts to adjust the output of the original tracks in Kodi (follower XBMC) were unsuccessful.
Your computer has three USB 2.0. However, in the Device Manager can be seen and the controller xHCI, although this model SoC it should not be. In any case, the real connections are made exactly according to the standard 2.0.
Recall that this version of the platform differs from the «desktop» fellow substantially limited set of external interfaces. In particular, it is not used SATA, or PCIe. Therefore, to connect the system drive Samsung MCGAFB 64 GB used tire eMMC.
Broadcom Wireless Controller supports standard 802.11b / g / n 2.4 GHz. In testing, we were able to obtain a maximum connection speed of 65 Mbit / s, the characteristic bulk tablets. Thus it is connected via an interface SDIO, which also imposes limitations on performance. In particular, the technology of the wireless display can be used to broadcast the images and presentations, but not video or other requiring high flow and quick response applications.
In the configuration of the computer also includes an adapter Bluetooth, connected to the serial bus. It supports standard 4.0 and BLE (Bluetooth Low Energy). The latter makes it possible to use the model for the management of various sensors and actuators. However, this would require the presence of specialized software.
No opportunity to change the hardware configuration of the device is not. If you look under the hood, you will see the main PCB, having dimensions of about 116 × 101 mm, an additional charge to the front USB connector and the power button, antenna wireless communication module and a small battery. The latter can ensure operation of the device for a few minutes and is designed to save more in order to move the device between different placements than for autonomous operation. Note that the operating system is not visible.
The large number of empty slots on the circuit board and battery presence suggests that this model has turned out rather «accidentally» left over from the production of a tablet components than was specially designed «from scratch». However, in the history of the emergence user experience device, of course, has no effect.
The computer has been tested with 32-bit pre-installed operating system Microsoft Windows with Bing. No additional software manufacturer or its partners has been established. Note that the use of the platform and influenced the way the operating system treats the device. In particular, when you press the Windows button in the upper right corner of the item was missing a power failure, the clocks could see a button to open the on-screen keyboard, and service utilities for system maintenance required special «Tablet» UEFI-loader.
Note that in addition to Windows, the manufacturer declares that this unit is compatible with Ubuntu and Google Android.
With a choice of competitors to evaluate the performance of a difficult situation. Traditionally, desktop and barebones we tested on the special original method , which run most applications on the device the class in question has no practical meaning. For comparison, we use the results of transformer Acer Aspire Switch 10 on the Intel Atom Z3745 and hybrid devices Intel Palace Hill on Intel Atom Z3740D. In terms of processor cores, these models have similar characteristics to the test computer.
We also used recently received the results of tests Futuremark motherboard ASRock Q2900-ITX based Intel Pentium J2900, which is the top for «desktop» segment Bay Trail. It has a TDP of 10 watts, frequency cores 2.41 / 2.66 GHz, faster graphics and external interfaces, as well as much more expensive. His indicators assess range performance platforms for tablets and desktops. Note that in testing this board uses two memory modules DDR3L-1333 with a volume of 4 GB and SSD Interface SATA, which also Povljana results.
Let’s start with the research unit of synthetic tests for individual components. We have already met with various options platform Bay Trail, so roughly understand what to expect from it. However, using manufacturer profiles CPU in different modes, parameters of memory, characteristic of a system drive and wireless controller significantly affect the responsiveness and comfort with the device.
In the absence of load processor cores to reduce the incidence of work up to 500 MHz. The temperature is in this mode is about 50 ° C. During normal operation of the system kernel can be overclocked using the Burst technology to the maximum for this model the frequency of 1.83 GHz.
When you run a stress test blocks of integer or real computing the frequency of processor cores rises to 1.58 GHz, which is higher than the «regular» 1.33 GHz, but less than the maximum value.Temperature cores after a relatively long life in this mode is 80-85 ° C.
The load on the graphics controller unit does not cause an increase in the frequency of operation of the main cores: in the first ten minutes of the test the temperature did not go beyond 80 ° C.However, at some point, the operating system has decided to exercise its internal affairs and involving x86-core. This caused a marked increase in temperature led to throttling.
Using a simple trick as a turning upside down the body will slightly improve cooling, since it is on this side of the board is the processor and ventilation holes, but to get rid of throttling is not possible.
Last load test we ran once for all available program components and overheating was not long in coming: just a couple of tens of seconds it took the system to exit the normal mode of operation.The frequency of processor cores jumped between 1.53 GHz and 500 MHz, and their temperature comes very close to 90 ° C.
In considering these graphs should not forget that created a synthetic test load practically does not occur in real life. So it is possible, of course, chide Developer for ill-conceived design of the cooling system, but in most scenarios the use of this device, this feature will not matter.
The computer is equipped with a single-channel memory controller that can have a significant impact on the speed performance graphics controller. However, if we talk about the absolute figures, they do not differ from other devices. And used in the product Acer chip with dual channel memory controller also shows similar results.
In the test GPGPU we too have not met anything unexpected, except that the processor does not add to the frequency cores to the maximum possible, as it was in other devices.
The installed system uses the bus drive eMMC version 4.5. The standard is the possibility of implementing data rates up to 200 MB / s, but the actual figures used by the drive expectedly much more modest, which confirms the test program CrystalDiskMark.
Sequential read barely exceeds 80 MB / s, and sequential recording is performed for about 36 MB / s. Even for the tablet is more than modest rates, and on the desktop last few generations the speed of the main drive is significantly higher. This is probably one of the main parameters, which should pay attention when adapting flatbed platform for microcomputer. It is likely that in the integral test this feature will play a role.
Compare the performance of the built-in storage with the work of memory cards and USB-flash drive. As the first model appeared SanDisk Extreme 32 GB and the external drive was introduced AData S007 8 GB.
As we can see, microSDHC slot and USB 2.0 port proved to be quite good for the platform. But let us recall once more that the usual external hard drives without any additional power supply used here will not work.
The device, despite the predominantly stationary use, equipped with only a wireless controller.However, to set SoC chip to connect wired network adapter nowhere. Unfortunately, the configuration of the device only supports 2.4 GHz, and connect to the router, we managed to up to 65 Mbit / s. At a distance of four meters without obstacles speed controller was 30-40 Mbit / s depending on the direction and the number of threads, which is consistent with the characteristics of the hardware device. However, in general, we would like to see in such models velocities support adapters 300 Mbit / s and 5 GHz. Moreover, that’s more than enough space to accommodate two antennas, and SDIO 3.0 specification allows for such speeds.
On the synthetic tests is difficult to find any significant differences from the family of platforms Intel Bay Trail-T.Now let’s see what the tests show Futuremark. For evaluation, we used the integrated benchmark PCMark 7 PCMark and 8 (mode «accelerated»), as well as graphic benchmark 3DMark. For a more correct comparison with other systems last run with a screen resolution of 1366 × 768 pixels, although formally render scenes Ice Storm and Cloud Gate by default works with a fixed resolution of 1280 × 720, and then the image is scaled for display.
In the utility PCMark 7 we see noticeable lag of the system from the competition in some scenarios, but a significant gain in Lightweight and Productivity. Such differences explain quite difficult. Maybe it’s the setting for processor cores or in updated versions of the drivers and operating systems. Unfortunately, internally compare devices on the same software versions opportunities we have.
PCMark 8 package has fewer templates and does DUT behind by 10-20% from coming very close to other participants in the comparison. Despite the formal smaller numbers, in real operation Foxconn solution differs little from products Acer and Intel’s user experience. True, it is difficult, using a standard mouse, keyboard and a large display, perceive it as a model for mikroPK flatbed platform, rather than the usual desktop computer with a fast multi-core processor Intel Core line and this SSD.
In the graphic test 3DMark we see most noticeable lag Ultra Nano PC from other members. And to explain the difference of 40% in the test Ice Storm at a slower drive or the driver is already difficult. We try to look for any performance-related options in the BIOS, the more that go into it with the regular keyboard is no problem, but to find out affecting the integral parameters of the test results was not possible. On the other hand, the product is not designed for game usage scenarios and office tasks to view videos and it copes.
Before the overall evaluation of the results should be noted that the manufacturer of platforms in the family Bay Trail tablet at the time of this writing, there were more than a dozen models. And the comparison table on the official site does not provide detailed data about their differences, which had carefully look in technical documentation. In addition, these solutions may have certain configuration parameters, asked the manufacturer of devices that can affect performance. Of course, in most cases the same chip will show similar results, but in comparison with the traditional desktop platforms dispersion may be substantially higher. The speed of adjustment can influence the frequency of the control unit and power supply, cooling system, the configuration memory, the model of the system drive and other parameters.
On the example considered in this paper a model based on almost the lowest in the current generation SoC Intel Atom, we see that the differences in the performance of other devices, depending on the test can be as minor and quite noticeable. However, these ready-made systems, supplied fully assembled, without the possibility of changing the configuration of the user and designed to work with a basic set of tasks, such comparisons do not play a big role. In most cases, more importance will be the cost, technical characteristics (for example, a set of ports or the type of wireless controller) and even design. About speed can only say one thing: for mass usage scenarios «Internet and office» it will be enough, and resource-intensive applications such as video editing or modern three-dimensional games, in any case require a «real» computer.
The modern market of IT solutions offers users a very wide range of products for the tasks at any level — from browsing the Internet to intensive computing. The latest generation of Intel Bay Trail platform turned out quite successful and is meeting today in tablets, compact computers and other devices. However, within this family there are significantly different in their characteristics chips.In adapting the product for mobile devices, requiring a significant reduction in energy consumption, the manufacturer refused such familiar desktop interfaces like SATA and PCIe. The result is a good autonomy, but the interaction with the system drive and the network was relatively not fast. In addition, some cuts were made and the memory subsystem.
In this article, we met with a rather unusual product — Foxconn Ultra Nano PC made in the form factor mikroPK, but uses a platform for tablets. It is hard to imagine that such a solution has been developed by Foxconn specifically: During testing we had the feeling that this model «tablet without a screen» was an accident due to an excess of finished boards or other reasons. Using one of the younger models Intel Atom has led to the fact that the computer was notable limitations hardware configuration and performance. Also not very clear choice of glossy cover housing, food from the Micro-USB port and a lack of attachment to the monitor, but this is a minor quibbles.
On the other hand, Foxconn Ultra Nano PC, a compact, quite nice and comfortable. It works absolutely silent, able to provide sufficient mass for performance problems and it is appropriate can look in the nursery as a computer for a child or in the living room near a large TV.
On the issues of cost and configuration of the operating system until there are no answers. Similar to the device configuration on foreign trading platforms offered about $ 100. Among them we can find a clone considered in this paper model.
