Smart TV Raiders: What are the differences between single-core, dual-core and quad-core in HD network set-top boxes?

Today's high-definition network set-top box market, dual-core and quad-core each occupy half of the country, single-core configuration of the box basically out of the market, can be ignored. The new box currently listed uses four cores, and the gradual dual-core will become the past tense. Many small whites will ask, what is the difference between the single-core, dual-core, and quad-core of the set-top box, or where is the difference?

In 2012, the HD network set-top box market was almost entirely a single-core configuration box. Due to its unsatisfactory performance and lack of functionality, it was unable to open the box market. By the beginning of the year, the dual-core configuration box had flowed into the market, and its functions were more abundant and mature, quickly defeating single-core. The TV box went to the mainstream market. At the end of the 13th year, the four-core configuration set-top box had been formed. Today, the quad-core box is in full swing.

From the evolution of the number of cores in the set-top box, we know that single-core configuration boxes are inferior to dual-core boxes, and dual-core boxes are inferior to quad-core boxes. So what are the differences between them?

In simple terms, the difference is that with the increase in the number of box cores, the set-top box's performance is getting better and better (not including special cases), such as faster running speed (faster screen switching), faster decoding capability (capable of playing video The format is more) stronger, the picture is clearer, the colors are more abundant and so on. In addition, you can also play large games, watch 3D formats, and 4K ultra high-definition movies.

What is the special situation? The factors affecting the performance of STBs are not only the number of cores, but also the core processor architecture, nm manufacturing process, and main frequency. In other words, single-core box performance is not necessarily weaker than dual-core boxes, and quad-core boxes are not necessarily Stronger than dual-core box. Judging their strengths and weaknesses, in addition to the number of cores to be considered, there are the above-mentioned processor architecture, nm process, frequency, memory, etc.
