The smart TV thing: 10 nuclear, 20 nuclear, full of routines


The smart TV industry now has a turbulent circle: Many manufacturers do not pay attention to the color gamut and backlight of TVs when they advertise, but instead compete with the number of processor cores, from 2 to 4 cores to 10 or even 20 cores. To be honest, this kind of Propaganda copy has no practical reference value for users.

What does the number of smart TV cores mean? 】

Under normal circumstances, the number of cores of smart TVs refers to the number of CPUs - the number of CPUs. In the case of the same CPU architecture and model number, more cores do represent stronger hardware performance; but if the processor models and The architecture used is inconsistent and this data loses its meaning.

For example, in 2017, the flagship smart TVs used more cortexA72 and cortexA53 processors, and the dual-core A72 has better performance than the quad-core A53 (some very powerful TVs use dual-core A72+ quad-core A53 processors).

[Ten core, twenty nuclear processor how come? 】

It is precisely because the number of processor cores does indeed represent the performance of television hardware to a certain extent, so many manufacturers will be in addition to CPU GPU, co-processor, and even Bluetooth and WiFi module also count as the core number of television, this word game The direct result is that many users who are not familiar with the industry are taken advantage of.

[What are the functions of GPU and co-processing? 】

The GPUs and coprocessors of smart TVs are relatively less well-known than CPUs, but they are also responsible for different functions as an important part of the hardware performance of smart TVs.


GPU: The graphics processor, also known as the display core, is a dedicated processor in smart devices designed to perform image and geometry calculations. In smart TVs and TV boxes, the GPU is responsible for all types of video decoding (especially hard solutions). And 4K decoding).

Coprocessor: It is an auxiliary processor that belongs to the CPU and GPU. By extending the instruction set to enhance CPU processing performance, one CPU can connect one or more coprocessors.

[Write in the last]

Today, smart TVs generally use ARM's Cortex series processors. Consumers can pay attention to the smart TVs equipped with a quad-core A53 or higher when purchasing. As for the 10 cores and 20 cores, you can ignore them.
