In the previous report, we also introduced domestic manufacturers Quanzhi A31 chipset It uses the new quad core ARM Cortex-A7 CPU with the GPU of Imaging PowerVR SGX544MP2. Some rumors before even said that the A31 used an "eight core" GPU, the SGX543MP8. This surging performance is enough to make the iPad 4 feel pressure. However, it was later confirmed that it uses a dual core GPU. What will its performance in practical applications be?

First, let's look at some parameters of Onda V812:

Screen: 8-inch 1024 * 768 resolution IPS ultra wide angle screen;

SoC: Quanzhi A31 quad core 1G processor (based on ARM Cortex-A7), equipped with PowerVR SGX544 MP2 display chip;

RAM: 2GB DDR3 dual channel 64bit wide memory;

Camera: 5 megapixel autofocus camera+300 megapixel front camera, 0 delay, 10 consecutive shots per second;

Decoding performance: 4K UHD video playback, Blu ray 3D playback.

From the parameter point of view, although it can not be said to be the top configuration, it is in line in all aspects. Among them, the most striking one is the all-time A31 SoC, which is equipped with a quad core 1G processor based on the A7 core, which we rarely contact. For the GPU, the SGX544MP2 of the relatively common PowerVR SGX series is used, and the frequency is 300MHz. The theoretical performance is the same as that of the SGX543MP2 on the same frequency (that is, the GPU used by the iPhone 4S and iPad 2). Therefore, this evaluation also focuses on testing the performance of this strange SoC.

Product appearance

packing

The package is obviously printed with "four core eight display processor". Of course, such a statement can easily mislead consumers into thinking it is "eight core graphics card".

There is no doubt that the appearance of the product and the general Android tablet are pure black on the front, and only one front camera can be seen.

The rear cover has a frosted all metal design.

At the bottom of the fuselage are most of the buttons and interfaces of the fuselage, from left to right are home, tf card slot, microphone, microUSB, HDMI and power on button. The design here is very "wonderful". It is rare to see the power on button of Android tablet set to the bottom of the body. In addition, the virtual key at the bottom of the screen already has a home key. It is strange to set an entity home key. What is more puzzling is that there is no physical volume key on the machine body, and the volume key is also realized through the virtual key (machine cleaning party: how do I clean the machine?).

There are speakers and 3.5mm connectors on the top of the fuselage.

Accessories and related instructions.

UI

The UI of Onda V812 is similar to that of ordinary Android tablets.

Although the overall Android tablet is the same as the general Android tablet, the V812 is "making a big fuss" on the virtual keys, and there are six virtual keys... They are the return, home, multitasking, and the unique screenshot and volume keys of the V812. This practice is actually not good. When the notification bar needs to display certain icons in the vertical screen state, it is easy to conflict with the virtual keys. For example, the menu keys in the following figure have overlapped with the screenshots and icons in the software market. This experience is not good.

The performance of the built-in 4K video player will be demonstrated below.

Compatibility of common software

Android has some applications with HD suffix, and V812 basically has no problem using this type of application.

performance testing

The SoC of V812 is a very rare Quanzhi A31 on the market. We are also interested in its performance. Here are some performance tests.

The score of Anthare is not low for a product with 1G dominant frequency. The GPU performs well, mainly because the A7 quad core limits the performance.

Nenamark， When the frame is full, the SGX544MP2 is sufficient for such a resolution

GLBenchmark， This is the strength of "Eight Evidences" in the propaganda, and the strength of Samsung Exynos 4412 Mali400MP4@533MHz The score is about the same, which can meet the requirement of 720P resolution.

Practical operation demonstration, which is demonstrated by video, including common software, web pages and games, and focuses on testing the video performance of V812.

summary

From this evaluation, we found that the performance of V812 basically reached the expected level. In terms of CPU general performance, it can basically meet the requirements of daily use. For the GPU part, the performance of the SGX544MP2 itself is not weak, and the resolution of the V812 is not high, so the smoothness of the game is not a problem. But also because the resolution is too low, resulting in poor display effect, affecting the actual experience. For the Quanzhi A31, the author believes that it is appropriate to use a 7-inch 720P screen, which can not only meet the user's visual requirements, but also maintain a high level of fluency. In addition, Quanzhi A31 is indeed extremely powerful in decoding performance. Of course, it needs to be used with its own video player to give full play to its due performance. Finally, the author believes that manufacturers should not use display engines as propaganda. The statement of "eight displays" can easily mislead consumers into thinking that this is an "eight core" GPU. Parameters. It's really better.
