complete evaluation of cube U30GT dual core peas
We always feel expecting and reluctant at the mere mention of Chinese tablet. Its low price and complete function draw great attention from those who are in need of tablet computers but with not too much money. But we can hardly be satisfied by the poor function and poor user experience, which makes the upgrade of the hardware of Chinese tablet computers a must. When the mainstream high quality tablet computers begin to set foot on four cores, the dual core Chinese tablet computers is taking off. The pioneering product of Chinese chip named Ruixinwei from Fujian Province is on its way to develop the most advanced RK 3066 dual core and it also makes research on the assembly of dual core CPU and quad core CPU, which offers great hope of Chinese tablet computers for the most consumers. Chinese tablet market is about to change. But we only hear news about the tablet computers of RK 3066 in the market; none of us have opportunity of seeing it. Just as we are going to exhaust our hope, the senior brand Cubic brings its first tablet computer with Rk 3066 dual core——U30GT dual core pea.

cube U30GT dual core peas
We have made simple technical analysis and comparison of RK 3066 previously, but those conclusions are only based the information published by producers. It may fail to symbolize the real function of the core and the real effect of the products in the market. So the Cube U30GT dual pea that is about to hit the market becomes considerably important. It is not only a symbol of excellent Chinese tablet computer that is about to hit the market, it is a precious opportunity for us to have a complete understanding of RK 3066 chip which is going to be applied in Chinese tablet computers widely. So we are gonging to make a complete functional test aimed at user experience on Cube U30GT pea. Friends who have interest in dual core pea, RK 3066 chip and Chinese dual core tablet computers should open their eyes and take a look at the evaluation today.
Of course the highlight of Cube U30GT dual core pea not only lays on its dual core processor, it combines a large number of elements which will draw great attention from you. It is rearranged as below.
10.1 inch screen using IPS material
Screen resolution ratio 1280*800
Dual camera on front and back two megapixels. The camera on the back is fitted with flash light.
Support OTG HDMI
Bluetooth
RK 3066 dual core processor the maximum frequency of single core reaches 1.6 GHz and quad core Mali 400MP GPU
Support 1080P HD video
Android 4.0 operational systems.
Appearance——amazingly thin and light
We have known previously that Cube U30GT dual core android tablet is using 10.1 inch screen whose aspect ratio reaches 16:10. There are few tablet computers using the same screen size in the prevailing market nowadays.
available in one hand
thickness 9.97 mm
real weight
As a matter of fact, the real effect of screen which is 10.1 inch and the aspect ratio reaches 16:10. You can have a very impressive user experience when reading eBooks, watching videos and browsing websites. There are few Chinese tablet computer using 10.1 inch screen in the market nowadays, because they have faced with problems of the productivity of tablet screen. Another factor is that Chinese brands have encountered technical problems in developing large size screen. Anyway large screen is sure to bring problems of portability. Even thought the users do not have the intention of portability, the thick and heavy body will soon make users who want to play in bed before sleep lose their interest?
foreside outlook
backside outlook
But Cube U30GT dual core pea indeed gives us a big surprise in its appearance. The real thickness is 0.97 mm and the weight is no more than 667 grams, which is a lot thinner and lighter than T 20 which is of the same size. It does not have big difference in weight in comparison with mainstream international brands such Samsung and ASUS whose screens are of the same size.
As for the material of its outer part, Cube U30GT dual core pea adopts panel of tempered glass. And the back of the panel adopts design of metal wrapped along its side. As for the back panel which uses design of engineering plastic, and we have reasons to believe that consumers will feel disappointed about this point. Compared with metal material which shares the virtues of excellent texture and stability, engineering plastics may seem to be a little poor in quality. But the introduce of plastic material can help to lower the developing cost of mould in a great extent and it has the advantage of eliminating the disturbance of Wi-Fi signal relatively.
Appearance——complete interfaces port
Even though the Cube U30GT dual core pea enjoys considerable thinness, we will rarely feel disappointed about the interface port of Cube U30GT dual core pea. Besides 3.5 mm earphone port, data transfer port, TF card extend port and DC port, it is endowed with HDMI high quality port and its Micro USB data transfer port has the function of OTG and makes the connectivity of mouse and USB flash disk devices.
interfaces port along the side
We use Logitech M505 wireless mouse, Sandisk 4G USB flash disk and card reader which uses OTG connectivity to test the OTG function of Cube U30GT dual core pea. We have found out that all these devices perform perfectly in their connectivity with Cube U30GT dual core pea. It also supports instant hot plug of attached storage devices. It makes read and save available after a short period time after connection. The speed of read and save depends on the quantities of data stored.
button details
Loudspeaker details
Besides the complete interface ports, Cube U30GT dual core pea has all of its physical buttons and loudspeaker along the interface side. Because the complete button assembly of Android 4.0 operational system lowers the performance of physical button application, Cube U30GT dual core pea only designs power button and two buttons for sound volume modulation. If we happen to have situations of system halted, we can long press power button to shut it down by force.
As for loudspeaker, the thin panel of course fails to support better loudspeaker devices which acquire too much for Cube U30GT dual core pea itself. Even though the volume of the loudspeaker along its side is by no means low, the quality of sound and the lack of stereo sound make the use of loudspeaker a poor experience. So the best way to avoid such problems is to wear earphone or external loudspeaker box including Bluetooth loudspeaker box.
Appearance——the effect of dual cameras
Cube U30GT dual core pea is endowed with dual cameras on the front and back side of the panel. And they both reach two megapixels. You can take photos and shoot videos and even make full scenery photos with it. But to our disappointment, neither of the cameras supports focus. but one of the highlight is the camera on the back is equipped with flash light which will help to promote the shooting effect in conditions that there is not enough light.

shooting picture
There is several pictures as follows:
backcamera with flashlight on

We can easily find that the shooting effect of Cube U30GT dual core pea is no better than common Chinese tablet computer. The details of image and sharpness are far from satisfactory. Now the shooting effect of Chinese tablet computer needs urgent promotion. We have reasons to believe that the camera will be the main point that requires promotion in the next generation of Chinese tablet computers.
Screen—— IPS screen performs perfectly
We have made an introduction concerning the screen configuration of Cube U30GT dual core pea which adopts 10.1 inch screen, the aspect ratio of which reaches up to 16:10. And the resolution aspect reaches up to 1280^800. The material of Cube U30GT dual core pea adopts IPS material which is loved by most users, for it supports full scale watching effects.
color stage test
grey stage test
gradual stage test
vision angle test
As for aspect of colors, we still make experienment with several regular pictures. The testing environment has no light. the screen lightness has been set as its maximum in experienmental conditions. Because the photos shot by cameras may fail to restore the performance of the real screen, the photos that list below is merely a reference. You may judge by yourself about its evaluation performance.
We may be left with the impression that the screen of Cube U30GT dual core pea has a real perfect performance. Every test reaches high standard of its own. The different colors distinguishes from each other and the transition performs smooth and natural. The entire color seems a little warm and the maximum light is well enough for its own. At the same time we can find that the color contrast and saturation of Cube U30GT dual core pea featured intensely as the characteristic of IPS materials. Unlike the rich colors produced by AMOLED materials, everything is quite moderate and performance perfectly and it feels very comfortable to human vision.
As for the aspect of available angle, Cube U30GT dual core pea combines the all angle watching effects inherited from IPS screen which outnumbers its rivals. To our surprise, Cube U30GT dual core pea shows no signs of dark color and deviation of colors even under small angle conditions.
Screen——excellent touch experience
As for the aspect of touch experience, the screen supports ten points capacity touch control. The test of touch control follows methods that list as below: use a drawing software of the tablet computer and draw diagonal line from the very edge of the panel. By watching the deviation of the diagonal line, we can draw conclusions about the function of accuracy of the touch control function and any signs of drift phenomenon and so on.
ten points touch support
straight touch control trace
In comparison with the touch control test of other Chinese tablet screens which usually perform tiny deviations of touch trace under low resolution and large deviations of touch trace under high resolution, Cube U30GT dual core pea shows no signs of deviations of multiple straight lines even under screen resolution of 1280*800, which is really a surprise for all of us.
I always think Fruit Ninja is the most convenient application of touch control test. This game not only has high standards of graphic processing abilities, it requires high demands of the optimization of touch screen effects. Every time I get a touch control phone or tablet PC, I will always turn first to Fruit Ninja to test the performance of this game.
scene of Fruit Ninja
final stage of Fruit Ninja
After a try out of this game, I think the performance of Cube U30GT dual core pea si rather perfect. The game proceeds smoothly and it recongnize the slide touch trace accurately and shows no signs of delay. Under the banana game mode of Fruit Ninja, there is always a phase of sliding pomegranate in the last five seconds of each game, at this time we can slide back and forth with two fingers to get high scores. When I was using iPad with this situation, I can mostly get more than 45 scores in five seconds in most cases. But I can only get about twenty scores with previous single core Chinese tablet computers due to its inaccuracy of two point touch recognization. I can safely make it more than 30 scores with Cube U30GT dual core pea. From this perspective, we can say the touch control experience of Cube U30GT dual core pea is really a promotion compared with previous Chinese tablet computers but still shows space of improvement.
Function——analysis of hardware configuration
the hardware configuration of Cube U30GT dual core pea adopts the most advanced RK 3066 processor developed by Ruixinwei. Based on the 40 nm procedure of TSMC, it makes low power consumption under the situation of high quality. The processor adopts ARM Cortex A9 dual core CPU with frequency of 1.4 GHz combined with quad core Mali 400 MP GPU. It is also added with Artisan processor POP. In theory it can promote the function by 10% to 20% compared with the same platform. that means three times more than prevailing single core tablet computer. the quad core CPU supports OpenGLES2.0/1.1和OpenVG1.1 which pave the road for three dimensional effects and fluent HD video.

comparison of chips
Now we are going to compare the configuration of the dual cores of several Chinese tablet and help you better understand this chip made by Ruixinwei RK 3066. We are going to recognize the hardware configuration of U30 GT dual core pea by using software named Antutu.
hardware configuration
We can see that the main frequency of Cube U30GT dual core pea reaches 1.6 GHz with the help of 1 G MAR memory and 1 G ROM. the screen resolution ratio is 1280*752 is due to the Android 4.0 operational tools. In addition to that, the system version of Cube U30GT dual core pea is the most updated Android 4.0.4.
Function——software evaluation result
As for the evaluation of the function of Cube U30GT dual core pea, we still use several authoritive evaluation software based on Android operational system. Every software will evaluate three times in order to avoid the unstability of the result of software evaluation. We choose the second as an analysis.
Quadrant test result
test result of single Linpack reaches 58.707
test result of Linpack reaches 99.862
Quadrant Advanced is one of the oldest and the best known functional evaluation software based on Android platform. It is based on Java language and aims at one key entire evaluation of CPU, memory, two dimensional graphic, three dimensional graphic, input and output. It offers multiple comparison among several mainstream portable devices, which will help us to have an understanding of the overall function of the tablet computer more directly. the evaluation is based on the most updated 2.0 version. and the promotion lies on that it optimizes Android 4.0 operational system and its multi core processor and helps it to be more complete.
Nenamark highest score is 62.7 FPS
Nenamark2 highest score is 41FPS
Supper rabbit AnTuTu Benchmark is a software designed especially for the hardware test and evaluation of phones and tablet computers based on Android operational system. It can finish launching evaluation by one key control and make evaluation of memory function, CPU digit function, CPU float function, two dimensional graphic function, three dimensional graphic function, data base I/O and the reading and saving of SD card and marks on the entire phone and single hardware aspect. The software we are using on evaluation is the most updated 2.7.3 version.
Linpack has made itself the most popular benchmark used mostly in the evaluation of high performance computer system internationally. with the help of high quality computer, we can evaluate the float function of high quality computers using a series of serious test of mathematical methods. compared with computers, the Linpack software of Android version is relatively simple. the most updated version consists only of single and multiple thread tests. the test result will be shown in terms of Flops. the high the score is, the better the performance of the tablet computer will be. this test is based on the most updated 1.2.8 version.
NenaMark is a tool used for evaluation of graphical performance based on OpenGL ES 2.0, including Nenamark1 and Nenamark2. Compared with Nenamark1, Nenamark2 requires higher demand, mostly aimed at high quality. it is the first choice for GPU function test. the process of the evaluation is to launch a section of three dimensional graphic. the final result is shown as FPS. the larger the number is, the better the quality is. this test is based on the most updated 1.8 version.
Compared with the result of test that listed above, we have reasons to believe that the software performs perfectly in every respect. it has surpassed Samsung and Texas Instrument and shows the perfect hardware performance of RK 3066.
Experience——the compatibility of programs
the score will show the performance of the hardware configuration and the user experience is connected closely with the OEM optimization in later stage. that is always the weak point of Chinese tablet computer all along, will the Cubic U30GT dual core pea bring us any surprise?
since Cube U30GT dual core pea adopts a rather new chip, we also pay plenty of attention to the compatibility of programs. we are going to make an evaluation using several common software about its compatibility.
After a series of tests, it is capable of launching most of prevailing application software. we have reasons to believe that the programmable compatibility of Cube U30GT dual core pea is well worth our trust.
Experience——the experience of games of various kinds
There are a large number of players who are fond of playing games using tablet computers. it is really a waste if Cube U30GT dual core pea is not used in playing games considering its excellent screen effect and perfect hardware performance. we are now going to make an evaluation in terms of games on Cube U30GT dual core pea.
nice compatibility in common games
First of all, we made a test of compatibility of Cube U30GT dual core pea on several prevailing games. Except for Warrior 2 and Train Crisis, other games such as Excitation Tour Boat, Where’s My Water and Plants VS Zombies can all be well supported.
since the quad core Mali 400MP high quality GPU adopted by Cube U30GT dual core pea resembles Samsung processor in every possible manner, game data of Samsung will be the best choice.
N.O.V.A. 2
City Race 6
Dungeon Hunter
After a series of tests, Cube U30GT dual core pea fails to support several large games such as Real Soccer 2012, Rugby Nations and Brothers in Arms. But it offers support for Asphault Urban GT 6, NOVO 2 and Dungeon Hunter. though the graphic of Asphault is rather rough, but considering its performance in improved gravitiy sensor, the user experience is rather good.
Experience——tests of network applications
web surfing is a basic functional demand of tablet computers. but Chinese tablet computer used to perform unsatisfactorily in this part. what will be the performance of Cube U30GT dual core pea?
Let us turn first to its signal strength of Wi-Fi. the testing environment is the local area network framed by home wireless router and there is about five meters in between the tablet computer and router with a solid wall and the door closed in between. the test of Cube U30GT dual core pea is made by using the software named Wi-Fi Analyzer.
moderate Wi-Fi signal
After a series of test, the performance of signal strength of Cube U30GT dual core pea is not so excellent as we have expected and seems a little weak compared with prevailing tablet computers. and the signal strength is not strong enough and is filled with deviations and fluctuations. the stability of Cube U30GT dual core pea is rather unsatisfactory.
As for real experience, what makes it amazing is that Cube U30GT dual core pea has been installed Flash plug-in before leaving factory which saves users from managing to seek for suitable Flash plug-in.
HD online video (Flash mode)
HD online movie (Flash mode)
Cube U30GT dual core pea performs nearly perfect in terms of loading speed of website and control fluency. Even with websites with a large number of Flash plug-in, Cube U30GT dual core pea is capable of finishing loading of texts, photos and Flash of the website in less than ten seconds. And the ability of page dragging and control fluency has made a jump in comparison with Chinese tablet computers in ages of single core.
Its excellent effect of Flash supporting also helps the tablet to load online videos in Flash mode with only a tiny loss of loading speed.But users can have a better experience of watching online videos via HTML 5 mode.
Experience——evaluation of video playing
In this section, we use several 1080P video of different formats to test the capability of Cube U30GT dual core pea in video playing. And we use the built in player to help with hardware decoding. The result of the test is listed as follows.
| video name | video format | video code | frame number | audio code | Cubic U30GT dual core pea |
| Avatar 1080P prevue | MOV | AVC 1 | 24 | AAC 2 | good |
| King Kong 1080P | WMV | WMV 3 | 24 | WMA 9 | bad |
| Westlife & Boyzone. Live | MP4 | AVC 1 | 25 | AAC 2 | good |
| Eminem Not Afraid | MKV | AVC 1 | 24 | AAC 2 | good |
| Lady Gaga Born This Way | MKV | AVC 1 | 24 | AC 3 | good |
| Taylor Swift Mine | AVI | MP4 | 24 | MP3 | good |
| Van Helsing | WMV | WMV 3 | 24 | WMA 9 | bad |
| Harry Potter and Half Blood Prince Prevue | RMVB | XVID | 24 | MP3 | good |
| TS format prevue | TS | MPEG 2 | 30 | DOLBY AC 3 | good |
| 007 and Casino Royale | AVI | XVID | 24 | MP3 | good |
| Snow in the Wind HD | FLV | AVC 1 | AAC 2 | so-so | |
| ASTRA HD Demokana | TS | AVC 1 | 25 | MPEG 1 | good |
| HD test section Haier LED | WMV | WMV 3 | 30 | WMA 8 | so-so |
test result of video playing
We can easily find out that among all those 1080P video files of different formats, there is only a small fraction of all those which fail to be supported by Cube U30GT dual core pea. And to our surprise, it shows improvement in its ability of decoding in comparison with RK 2918. 007 and Casino Royale which used not to be supported due to audio track complications can be played on RK 3066 and is of considerable quality.
The only problem facing Cube U30GT dual core pea is that the built in video player still fails to recognize external subtitle or switch between different audio tracks. It is required by the users to install third party playing software to make this happen.
Experience——battery capacity and heat emitting
The performance of battery capacity and heat emitting, we have reasons to believe, is the focus that draws the most attention from a large number of users. Let us turn first to the battery capacity of Cube U30GT dual core pea.
Two batteries of which the capacity reaches 3600 mAh constitute the power supply of Cube U30GT dual core pea. Even though its capacity seems less powerful than the previous 8000 mAh battery which was deployed by Cube U30GT dual core pea previously, it adopts the most advanced 40nm technology RK 3066 chip. And it is fitted with more complete power supply control system. So there is wide spread expectation for its performance in terms of battery capacity.
We made our evaluation of battery capacity of Cube U30GT dual core pea in roughly two methods. The first one is to get Cube U30GT dual core pea fully charged and set the lightness of the screen as moderate and shut down Wi-Fi connectivity and shut down all the useless programs launching in the backstage. And we play a movie of MKV format repeatedly with built in player and made a census of the total time before it exhaust its battery capacity. The second one is set the screen lightness as moderate and shut down Wi-Fi connectivity and launch a video game for an hour and check out the situation of battery capacity.
The result of the evaluation did not let us down. Under the first circumstances, the total running time of Cube U30GT dual core pea reached as long as eight hours and twenty minutes or so. And under the second circumstances, the evaluation took up approximately 22% of the entire battery capacity. We have reasons to believe the such a final result will make the majority of us quite satisfied in every possible manner.
heat emitting position
As for heat emitting, the performance of Cube U30GT dual core pea is not as excellent as previously. It began to emit heat in less than five minutes after playing games, network online video playing and HD video playing and other kinds of applications. And as this situations proceed for a longer period, the surface temperature will reach forty degrees or so, which will in many ways impacts the user experience.
