Before listing the best Chinese tablet with 9.7-inch retina display with a resolution of 2048 x 1536 pixels is necessary to specify in broad terms what a retina display , the first time we meet this definition is when the iPhone was introduced 4 in June 2010 with a 3.5 inch screen whose pixel density was approximately 330 ppi, where ppi means pixels per inch (in English inches), in practice we talk about the retina display when watching a screen of a tablet or a smartphone to use the normal distance the human eye is unable to distinguish individual pixels .
So when we talk about the retina display three factors come into play, the screen size, the pixel density and distance from the screen, at equal distance, the larger the size of the screen will be greater the density of pixels in the true effect display retina.
There is a formula for calculating from the pixel density of a screen√ (l ² + h ²) / d in that translates words in the square root of the sum of the square of the height and length of the square the result divided by the size of the display in inches, for example, if we consider a tablet with display 9.7 inches and a resolution of 2048 x 1536 pixels density per pixel will be √ (2048 ² +1536 ²) / 9.7 = 263.91 approximately 264 ppi , the iPad Air has a 9.7-inch display with a resolution of 2048 x 1536 pixels and then a pixel density of 264 ppi, tablet with a display of this size are generally used at a distance of about 38 cm. Authoritative sources say that the display on the new Samsung Galaxy S5 will not be a Super AMOLED, but it will have a 5.25-inch Sharp LTPS panel with a resolution of 2560 x 1440 pixels (2K) this means that it will have a pixel density of about 565 ppi , surely it will be impossible to distinguish individual pixels!
But what are the best Chinese tablet as quality / price that have a retina display?'m going to find on a Chinese store for tablets and smartphones busy, and I do a search pandawill.com applying as filter screen resolution to 2048 * 1536, this research'm in total about 14 tablet, I will list only two models, the ones that in my humble opinion are the best in quality / price.
PIPO M6Pro 've already classified in another article as Tablet Best Chinese in 2013 , in addition to multi-touch retina display 10 points , the most interesting features of this tablet are the 2GB of RAM, 32GB of internal memory, micro USB OTG, Bluetooth , GPS, WiFi 802.11 b / g / n, HDMI mini port, 2-megapixel front-facing camera and rear 5-megapixel camera with flash, lithium battery 10000 mAh well, as we have Android 4.2.2 operating system with support to play store, And there is also the model with the 3G module WCDMA 850/2100MHz, for those looking for a tablet complete with all connection types with an excellent quality / price ratio I recommend the purchase of PIPO M6Pro, also there is a decent online community that can support you in solving any problems, nel'installazione of custom ROMs and more. The lowest price on the web for the tablet Pipo M6 Pro 3G 32GB I found out pandawill.com chinabuye.com and where it is sold at a price of about 290 dollars. The weak point of this tablet is the graphics processor, in fact, the GPU is a Mali 400 MP4 that are on all the tablet with Rockchip RK3188 SoC (very common among Chinese and among the android tablet android mini pc ), the performance of this GPU are lower than the PowerVR GPU SGX544 MP2 (GPU that is in the best Chinese Android smartphone quad-core chipset MT6589T), Mali-450 MP4 700 MHz (which we find in the best Chinese octa-core Android smartphone with MTK6592 SoC), Mali-T604 (the Nexus 10), Adreno 320 (7 in 2013 and the nexus nexus 4), up to the GPU flagship Tegra 4 (EVGA Tegra Notes 7 Xiaomi Mi3), Adreno 330 (Nexus Samsung Galaxy Note 3 and 5), Adreno 420 (Qualcomm Snapdragon SoC) and the latest Nvidia Tegra K1 just announced at CES 2014 SoC that we will probably see installed in the tablet on the market during 2015 (I could not even mention it). If you want to make a comparison between the different 3D graphics performance you can use the tools that you can find on the site gfxbench.com / compare.jsp .
V975m WAVE is a tablet on the market for a short time, the most interesting features of this tablet with Chinese display retina are the new SoC AMLogic AML-M802 Quad Core 2.0GHz Cortex A9r4 manufacturing process to 28nm graphics processor with Mali-450 MP6 (Octa Core GPU) capable of playing video in 4K (4096 x 2160px).

Q Colorfly the CT972, the Soxi X5, WAVE WAVE V972 and V971 with SoC Allwinner A31 Cortex A7 1.5GHz quad core CPU and GPU PowerVR SGX544 MP2, has 2GB of RAM and 16GB of storage, 2-megapixel front camera, this is the tablet Android Chinese brand with retina display cheaper, it sells for about $ 170.
Waiting to see the first Chinese Android tablet with the new Rockchip SoC RK32xx with quad core CPU ARM Cortex-A12 up to 1.8GHz ARM Mali-T624 GPU and conclude by recommending the purchase of Pipo M6 Pro 3G 32GB for those who want a tablet with retina display full of all kinds of connections and has a budget of around € 250, while those with a lower budget, want a tablet with retina display and does not need to have a tablet with GPS and Bluetooth recommend the new ONDA V975m .
