Ultrabook ASUS ZENBOOK UX305FA: review and testing

When in 2011 Intel presented a new and unique concept of a portable computer device, only few could have imagined that just a few years the ultrabooks will have a quite massive popularity. Today it is difficult to find a large manufacturer without at least one such gadget. But at the same time it became clear that new devices require an advanced hardware platform that can not fully function in such a compact space, but also seamlessly show a good result.


Best engineers from Intel decided to solve this complex problem. The result of their hard work was the development of a new generation of processors Intel Core M with record levels of performance and energy efficiency per watt of consumed energy. Thus, compared with the previous generation, it was possible to significantly reduce the level of heat (up to 60%), decrease the degree of power consumption (up to 45%) and to increase the processing power (40%) produced by microarray. And thanks to the introduction of the latest manufacturing process (14 nm), the area of the produced crystals was decreased by almost a half, enabling much more effective use of the available space, as well as deliver a portable device based on the new processors by the active cooling system.


In this review, we will look at a magnificent example of modern ultra-compact computer equipment - ultrabook ASUS ZENBOOK UX305FA. Also we will try to analyze the effectiveness of a new hardware platform powered by Intel, as well as learn what additional capabilities has this very interesting and very promising market segment.

urrently Sony is upgrading its mobile business, and shifts the focus to the decisions of the upper and middle price range. In this fiscal year Sony Mobile Communications plans to sell 38 million smartphones. Despite rumors about the rejection of the strategy of issuing new flagship models every six months, the Vice-President of Global Communications and Public Relations Tim Harrison in a recent interview said that the company decided to produce flagship models more frequently than once a 12 months. On the one hand, this solution allows to quickly take into account errors and to impose compete with other manufacturers.

AMD FreeSync is a reasonable response of NVIDIA G-SYNC 

At the end of 2013 for the conference NVIDIA Editor's Day the NVIDIA has told about the technology NVIDIA G-SYNC, designed to make a real revolution in the world of dynamic synchronization of the image between the graphics card and monitor. Up to this point the struggle for the purity of the frame without any noticeable discontinuities and other artifacts was conducted exclusively on the side of the graphics card. NVIDIA offered to synchronize the refresh rate of the monitor with a frequency GPU frame rendering, to remove not only the gap frame, but slowdown, as well as delays. The technology NVIDIA G-SYNC in more detail is described in this review, so let's move on to the goal of this review - familiarity with the main competitor in the form of AMD FreeSync.

AMD FreeSync

Surely the AMD management immediately realized the full extent of the potential impact of NVIDIA G-SYNC to compete for the hearts and minds of gamers worldwide. Furthermore, this technology requires a license, ie, AMD would have to pay a pretty penny for its adaptation to graphics cards. Given the precarious financial position of AMD, the question of such a scenario may not even raised in the leadership.

However, it was necessary intelligently to create an alternative: if consider the market of only video cards (not taking into account the integrated graphics core processor), the NVIDIA company occupies a dominant position. This means that the analog of NVIDIA G-SYNC with additional module is unlikely to appeal to many monitor manufacturers. Therefore, AMD has chosen a different path - an open standard, which does not require for additional fees and integration of special module.

So in May 2014 such review appeared «Adaptive-Sync» to the VESA-standard DisplayPort 1.2a, which realizes the technology AMD FreeSync. This means that all members of the organization VESA (which includes AMD and key players in the market monitors) may free use a new standard in the production of their monitors and to choose: to enable or disable support for this technology. Furthermore, AMD FreeSync was interested for company Intel, so the graphics core of processors Intel Broadwell will support it.

Open and free access of standard DisplayPort 1.2a Adaptive-Sync provides another competitive advantage: to reduce the final cost of the monitor that can serve for many key factor.

AMD FreeSync

Now let's look at the technical details of AMD FreeSync in more details. As many already know, conventional monitors has constant refresh rate (usually 60 or 75 Hz, although there is a version with an index of 120 and 144 Hz). But the graphics card renders frames at different rates. First of all it is important in games where we want to get the maximum quality of image, that is, with the best graphics settings and acceptable speed of playback (up to 24 fps). The comfortable readings are above 30 - 40 fps. Since many of today's games are very demanding on system resources, and the scenes are very difficult to handle even high-performance adapters, the speed of rendering frames is dynamically changed. Due to this, there are gaps frames (Tearing), when one part of the monitor shows the current frame, and the other the next.

AMD FreeSync

To remove this effect a VSYNC technology was developed: if the new frame is not ready at the time of refresh, the system duplicates the old one. This approach is effective in dealing with gaps, but creates new problems: Stuttering and Lag. In turn, this reduces the responsiveness of the mouse, so players later react to real changes in the virtual world, where one moment may divide winners from the losers.

AMD FreeSync

Technology AMD FreeSync allows you to synchronize the refresh rate of the monitor with the speed of rendering images, eliminating the effects of gap frame and lagging. In fact, the same thing performs NVIDIA G-SYNC. But AMD FreeSync has a number of additional advantages.

AMD FreeSync

We have already mentioned that it does not require the integration of additional modules and license fees, as well as based on open standards. It also supports a wide range of monitor refresh rate: 9 - 240 Hz vs. 30 - 144 Hz at a competitive counterpart. Of course, the implementation of a specific frequency range depends solely on the monitor manufacturer, but in a way they always have the opportunity to go beyond the standard framework or create a product in the frequency range where fit in terms of its price positioning.

AMD FreeSync

Another important advantage of AMD FreeSync is the support for the standard features of the monitor and the lack of impact on performance of gameplay. Firstly, it means that compatible displays can use more color profiles (for example, "Video", "Read", "Theatre", "Night view" and others), DisplayPort port can transmit audio along with the video, and the manufacturer can integrate additional video interfaces (though technology AMD FreeSync work will be supported only when using the DisplayPort 1.2a). Monitors with support for NVIDIA G-SYNC use only one color profile and one video interface DisplayPort 1.2a.

AMD FreeSyncAMD FreeSync

As for the impact to performance, AMD has even provided a comparative test, the results of which are displayed in the following table:


AMD FreeSync Off (FPS average number)

AMD FreeSync On (FPS average number)


NVIDIA G-SYNC Off (FPS average number)

NVIDIA G-SYNC On (FPS average number)


Alien Isolation







BioShock Infinite







Tomb Raider







Sniper Elite 3














As you can see, NVIDIA G-SYNC reduces the average number of FPS in the specified game only by 1-2%, which will not be seen in reality. At the same time, the use of technology AMD FreeSync does not allow increase playback speed even at 1%. That is the point of comparison is purely symbolic.

AMD FreeSync

We are talking about the behavior of technologies outside the designated frequency band. NVIDIA G-SYNC behaves if VSYNC is permanently activated when output for the specified range: if the frame rate is lower than 30 Hz, you can notice stuttering and lagging. Above 144 Hz frame rate does not rise simply because the GPU limits it at this point. That is, the priority is the picture without breaks.

AMD FreeSyncAMD FreeSync

AMD FreeSync allows the user to decide on their own how the system should behave outside the supported range: activate VSYNC, reducing the responsiveness of the mouse and their own actions, or not to use VSYNC, faced with a possible rupture of the image. In the second case, the upper limit is removed and the level of FPS can go beyond it.

AMD FreeSync

Take advantage of the new technology will not only owners of the top-end graphics cards, but the owners middle range graphics cards, as well as a series of APU AMD Kaveri. Do add also the above-mentioned series of processors Intel Broadwell. Many have a question: "Why the list includes the processor with features not enough for comfortable play of modern games?" The answer lies in the use of technology AMD FreeSync and other content. For example, you can synchronize the refresh rate of the monitor with a fixed video frequency without re-encoding of the file.

AMD FreeSync

Moreover, this opens the way to further reduce the energy consumption, which is particularly important in mobile systems. The fact that the standard DisplayPort 1.2a Adaptive-Sync is already compatible with the Embedded DisplayPort interface and supports «Static Screen State»: if the picture is static (no new content, for example, while reading a document), the frequency of updating is reduced to the minimum level. In conventional displays it is 60 Hz, and compatible with AMD FreeSync it is theoretically 9 Hz.

AMD FreeSyncAMD FreeSync

AMD FreeSyncAMD FreeSync

And finally, let's look at the issue of price. In the past, AMD has repeatedly stated that the above indicated benefits of AMD FreeSync will provide accessible compatibility of monitors. Is that true?

AMD FreeSync

The NVIDIA site has a list of currently available monitors with support for NVIDIA G-SYNC. As you can see, the cheapest is 24-inch AOC G2460PG with a suggested price of $ 399, TN-panel resolution of Full HD (1920 x 1080) and refresh rate to 144 Hz. The most accessible in the published list is AMD model LG 29UM67 at an estimated price of $ 449. Stated dynamic range is 48 - 75 Hz, but it has a 29-inch IPS-panel with a resolution of 2560 x 1080 pixels. If you need the display with 144 Hz dynamic refresh rate, while Acer XG270HU with a 27-inch TN-panel and resolution of 2560 x 1440 looks good alternative for $ 499.

AMD FreeSync

In general, manufacturers very warmly received the technology AMD FreeSync. AMD has reported at least about 11 models of top vendors with different diagonals (from 23.6 to 34 inches), resolution (from 1920 x 1080 to 3840 x 2160) and a range of frequencies (from 60 to 144 Hz), which have already been announced or will soon appear on the market. It is possible that many other players just wait; analyzing consumer demands, and soon they join one of two groups.

Smartphone ZTE Nubia Z7 mini: review and testing

Over the past few years Chinese mobile phone manufacturers made a huge burst in development. Until recently their products had a plain design, low-quality build quality, slurred hardware and software with uncomfortable control aspect. The appearance of Android OS greatly simplified life of the creator of such devices and at the same time increased competition between them. "Fashion" OS applied in smartphones of world-known manufacturers strongly pulled Chinese devices in terms of functionality, but at the same time has increased demands to the hardware. The Chinese unnamed devices became popular for user with higher demands in terms of performance and design.

After a few years of competition for buyers in the domestic and foreign markets the Chinese smartphones were completely transformed. Companies whose names are in our area were not popular now offer phones with flagship systems, high-quality screen and uninteresting design. This is complemented by current versions of the Android OS with useful add-ons from the manufacturer and affordable price.

Against the background of bold newcomers more notable Chinese companies are in an interesting position. On the one hand, their image doesn’t allow to skim the cream like global brands, often offering overpriced smartphones with outdated features. On the other hand, they cannot make price dumping as the cost is higher than that of their younger compatriots with a small staff and advertising costs.

ZTE Nubia Z7 mini

In such circumstances some Chinese brands try to offer smartphones with good quality equipment and technical support at a price slightly higher than "anonymous" devices, but much lower than that of identical offers from international companies. This class of solutions includes the smartphone ZTE Nubia Z7 mini. This model was bought by the author for personal use, and now will try to tell you about the pros and cons of this model.

Smartphone Sigma mobile X-treme PQ33: review and testing

Modern smartphone market offers an extremely wide variety of devices of different shapes, sizes, colors and technical configurations. In addition, it became quite popular to equip some solutions by protection against dust and moisture. A striking example is the top models Sony Xperia Z2 and Samsung Galaxy S5. Despite this, modern gadgets remain vulnerable even to minor mechanical effects, which require prudent care. While in most everyday scenario, it is quite possible, that in case of active life, sport or work under hazardous conditions (manufacturing, construction, mining, etc.) - it becomes extremely difficult. Protected smartphones offering increased resistance to external negative factors were created for such purposes. Typically, these devices cannot boast the best performance, which further limits the range of potential users. What would happen if such a protected case will have a considerable screen and efficient hardware platform combined with modern communication capabilities and technologies?

in the center is a stylish logo «sigma mobile» (under it there is a special induction coil for wireless charging). on the sides you can see textured inserts that resemble metal sheet with notches. at the bottom there is a strap hole or carbine.compared with conventional smartphones, the novelty has received significantly larger dimensions (150 x 78.5 x 18.5 mm) and weight (260 g), it is quite normal for this class of devices. on the one hand, coupled with some unusual arrangement of controls this leads to the need to adapt over some period of time. on the other, the increased size and weight, special materials and design features (non-slip borders or texture) provide a secure grip even with wet or dirty hands, which is very important in extreme conditions. in general, sigma mobile x-treme pq33 has excellent build quality (there are no defects, backlash or creaking) and stiffness of the structure (here is not even a hint of a deflection or deformation under moderate physical impact, the glass is not pressed, and artifacts on the screen do not appear).sigma mobile x-treme pq33 is equipped with high-quality 4.7-inch screen on the basis of ips-matrix with a resolution of 1280 x 720 pixels and a pixel density at 312 ppi. more than enough to display a very smooth font and get quite detailed image as a whole. even with a strong desire individual pixels considered unlikely to succeed.as already mentioned, sigma mobile x-treme pq33 has only one multimedia speaker, which is in the upper part of the rear side of the case (near the main camera lens). due to this location sound is muted when the gadget is on the horizontal surface of the screen up. furthermore, due to its protective properties inside the speaker is covered with a special waterproof membrane. volume is not too large, but quite sufficient for most everyday usage scenarios (watching videos, games). the sound is at a good level: middle and high ranges are detailed enough, but due to the lack of low-frequency sound seems a little flat. in any case, you can use the universal audio jack (mini-jack 3,5 mm) and connect headphones or external speakers.complete headset with vacuum type headphones provides mediocre sound. it has a minimum stock of volume and cannot boast of a wide frequency range: low and medium are almost absent, and high are too high. the sound in the headphones was tested by gaming (impedance 60 ohms) and vivanco hs 200 wt (impedance 16 ohms). it should be noted that due to the nature of the location of audio connectors (under the cap in a small cavity) wide connector of gaming headphones is not suitable. this situation did not happen with vivanco hs 200 wt, so you should consider this factor when choosing future peripherals. returning to the sound, it is quite pleasant, with good detail (there the entire frequency range) and sufficient volume (even with some margin).the novelty is equipped with two modules of digital cameras. front has a sensor on the 5 megapixel, fixed focus lens and aperture f/2.8. photography and filming is started in resolution 2560 x 480p and 1920, respectively.the main camera has received a 13-megapixel lens and an aperture of f/2.4. there are autofocus and single-section led-flash. maximum resolution is 4096 x 3072p. video has a resolution of 1920 × 1080 (30 fps) and a format 3gp. the base of sigma mobile x-treme pq33 is a productive 8-core processor mediatek mt6592, created on the basis of a 28-nm hpm process with application of the design arm cortex-a7. the maximum clock frequency of its processor cores reached 1.66 ghz, while the l2 cache is 1 mb. the integrated graphics card is presented as solution arm mali-450 mp4, i.e. four cores with a maximum clock frequency of 650 mhz. it received the support for opengl es 2.0 and openvg 1.1.set of communication features is presented modules nfc, bluetooth 4.0 and wi-fi. the latter has the support of protocols 802.11 b/g/n and features wi-fi direct, wi-fi hotspot and wi-fi display, but is able to work only in the range 2.4 ghz. in addition, there is support for the radio walkie-talkie (for the application provides "radio station"), operating in the civil range resolution of 446.000 - 446.100 mhz. transmitter power is 0.5 w, and the range can be up to 5 km. traditionally, there is support for dlna.the smartphone has the gps module with support for a-gps. the quality of its operation did not cause complaints: in an open area it quickly determines 12 satellites, and even more. connecting takes a little more than half a minute, and the connection is stable with the majority. "cold" start of gps-module takes up to 2 minutes. in terms of test accuracy of determining was at a level of up to 4 meters. as a result of viewing hd-video (mpeg-4 / avc, container mkv, stream 4 mb/s) at 50% brightness and active modules wi-fi and gps unit discharge for almost 10 hours. game simulation using asphalt 8: airborne at 100% brightness and active modules wi-fi and gps exhausted battery power for 4.5 hours. testing of autonomy by the popular benchmark pcmark (text editing, viewing video, photo editing, etc.) demonstrated the results of 7 hours at maximum brightness. estimated time of the smartphone according to the benchmark gfxbench is 165 minutes.battery charge time from complete unit (5 v, 1000 ma) is about 3 hours. in addition, the smartphone boasts of a possibility of wireless charging thanks to a special induction coil (located in the body of the device) and complete charging platform (mp01) of standard qi. the process of recovery from the wireless battery charging takes about 6 hours. another important advantage of sigma mobile x-treme pq33 is a function of charging of external devices (powerbank), which will be useful outside of civilization (without access to other sources of supply).undoubtedly, is one of the most interesting protected smartphones on the ukrainian market. traditionally, for its class the novelty has spectacular and quite formidable design with quality materials, sophisticated design and high quality execution. the smartphone boasts of dust and moisture protection in accordance with standard ip67, and can safely survive a fall from a moderate height. list of benefits includes a good hd ips-display with wide viewing angles and natural-colors, some good photographic opportunities of digital cameras (5 megapixel and 13 megapixel) with enough light, capacious lithium-ion battery 3500 mah and the latest version of the os android 4.4.2 kitkat. due to the use of efficient 8-core processor mediatek mt6592 and 2 gb of ram novelty is one of the fastest among the protected classmates. in addition, thanks to the support of two sim-cards and a wide range of communication capabilities (nfc, bluetooth 4.0, wi-fi, dlna, gps and even radio walkie-talkie) modern user will feel comfortable in everyday life and in the field.
