The Mediatek MT8382: the perfect solution for the entry-level tablet

MediaTek MT8382 is an excellent processor for entry-level tablets. It boasts the availability of just 4 compute modules, as well as support for mobile networks up to 3G standard. All this in the aggregate allows on its basis to implement an inexpensive, but very very functional tablet computer.

CPU niche

It is to the segment of the most affordable mobile solutions that MediaTek MT8382 targets. The characteristics of this chip this once again prove. Only four cores, which, first of all, are focused on energy efficiency and only then on productivity. Therefore, in the tablets based on this semiconductor solution, autonomy comes to the fore. And in this regard, they really stand out against the background of competitors. An important advantage of this model of the CPU is the availability of GSM-module, which also supports third-generation mobile networks. As a result, it turns out that this CPU is designed for tablets in the budget segment, for which autonomy is important and you need a direct connection to cellular networks.

Hardware parameters

The MediaTek MT8382 chip includes 4 computing cores based on the Cortex A7 architecture. First of all, they are focused on energy efficiency and only then on performance, an acceptable level of which is achieved only through an increased number of computing units. In the software package "AnTuTu" this processor solution shows a result of the order of 17000 points. According to this indicator, this CPU is a typical representative of budget-level devices.

Graphic accelerator

As a graphics accelerator in this case stands Mali - 400MP2. The clock frequency is 500MHz, and the maximum supported resolution is 1280px x 720px. Of course, it can not boast of an outstanding performance level, but its availability alone is enough to free the central processing unit from processing graphic information. This allows for an insignificant increase in the cost of a silicon crystal to obtain a significant increase in speed.

Possible frequency values

The frequency value dynamically changes MediaTek MT8382 depending on the complexity of the task being solved at the current time and on how much the semiconductor crystal of the central processor has warmed up. As noted earlier, the chip includes four computational units. If the application is optimized for 1 or 2 streams of information, the unused computing resources are automatically turned off. The minimum frequency of this silicon product is 420 MHz, and the maximum frequency is 1.3 GHz. The inclusion and deactivation of computing units, as well as the dynamic change in the clock frequency of each of them, ensures high energy efficiency of this CPU.

Memory cache

The MediaTek MT8382 processor is equipped with a two-level cache. The first level has a total size of 128kb. It is divided into 4 equal parts of 32kb. Which, in turn, are physically attached to a specific core. That is, in a certain part of this cache, only information with which only one computational unit works is stored. The total cache size of the second level is 256kb. It is divided into two parts, which can exchange information only with a certain pair of computing cores.

Technological process

This semiconductor crystal is produced using 28nm technology. To date, this process technology has become obsolete. The most advanced silicon solutions are already manufactured with tolerances of 20nm or even 14nm. But do not forget that this is an entry-level solution. Accordingly, it is not necessary to expect advanced technologies in this case. The lower cost of the product comes to the fore. And it is this advantage that gives a well-proven and well-proven technological process with a tolerance of 28 nm. Therefore, in this case, its use is more than justified.

The price and opinion of mobile device owners

Tablet PCs based on Mediatek MT8382 are great for solving the most simple and most common tasks. User reviews say that watching videos, unpretentious toys, surfing sites, listening to music - all this is performed on such devices without any problems. More demanding software applications also go, but you have to set the minimum settings. But this budget decision and expect "high speed" from him when solving more demanding tasks do not have to. On the other hand, in this case there are a number of significant advantages. This is low cost, this is the high energy efficiency of the CPU, this is the ultimate autonomy of the mobile device. Also in the composition of this chip is GSM-module, which is not in every tablet of this price range is.

Results

MediaTek MT8382 is an excellent processor for entry-level tablet PCs. In this case, its capabilities are more than enough. Well, if the requirements for hardware significantly increase, then you need to look toward more expensive gadgets.
