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

MediaTek MT8382 is an excellent processor fortablets of an initial level. 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.

Niche CPA

It is on the segment of the most accessible mobilesolutions aimed MediaTek MT8382. The characteristics of this chip is proving once again. 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 mobile networks of the third generation. 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

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

Graphic accelerator

As a graphic accelerator in thisThe case is favored by 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 level of performance, 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 MediaTekMT8382 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 information streams, 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 is equipped with a two-levelcache. 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 particular 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 producedtechnology 28nm. To date, this process technology has become obsolete. The most advanced silicon solutions are already manufactured with tolerances of 20 nm or even 14 nm. 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.

Price and opinion of mobile device owners

To solve the simplest and mostTablet PCs based on Mediatek MT8382 are great for 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 it 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.

Outcomes

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