Architecture is the key to measuring CPU performance
Many users tend to judge their performance from the number of cores and the highest frequency when purchasing a smart TV, and this is obviously very wrong.
Some TV manufacturers have attracted attention from users, conflated the CPU, GPU, and even the number of coprocessor cores, and used ten or twenty cores as selling points. In fact, they have no reference value for measuring device performance (whether they are smart TVs or TV boxes). Or smart devices such as computers, the so-called through the number of core, the frequency of performance, must be based on the premise of the same architecture, taking the ARM architecture as an example, the dual-core Cortex-A72 is better than the quad-core Cortex-A53 performance) .
At present, smart TVs often use processors based on the ARM architecture (including Amlogic and MSTAR). We can directly judge the hardware performance of the devices based on the processor rankings of ARM. From the top to the bottom, Cortex A75, A73, A72, and A57, respectively. A53, A35, A32, A17, A15, A9, A7, and so on (A9, A7 as a processor with higher cost performance, there is no practical significance down).
In 2017, the domestic flagship smart TVs used the A72 and A53 CPUs, which is the most recognized processor so far (the A73 and A75 were introduced soon, and they have not yet reached mass production).
Memory version can not be ignored
The better the memory, the better natural, but many people ignore the importance of the memory version. Memory is used as the medium for the CPU to store operational data. Its transmission speed also affects the speed of the CPU.
The memory is divided into four versions of DDR1, DDR2, DDR3, and DDR4. The transmission speed, power consumption, and even capacity vary greatly between each version. Today, the mainstream memory in the TV industry is DDR2 and DDR3 (DDR1 is eliminated and DDR4 is extremely rare). Targeted devices equipped with DDR3 memory can be selected.
Written at the end:
Hardware performance is the basis for determining whether a smart TV system is fluent. When buying smart TVs, we need to pay special attention; in addition, the release of cache should also become a daily habit. For devices that have a certain useful life, Brush is still an effective system. Optimization.
1.ANTENK Flexible Printed Circuit (FPC) and Flexible Flat Cable (FFC) connectors are ZIF (zero insertion force) and LIF (low insertion force) connectors designed to provide a fast, easy, reliable method to make a connection of flexible printed circuits to a PCB. Adam Tech`s special contact design completely preserves conductor integrity by eliminating all wiping action while making connection. Flex circuitry enters the connector and the connector cap is pressed down to capture the flex circuit producing a stable, high pressure connection. Raising the cap releases the pressure for exchange or replacement of circuitry. This series includes single and dual row versions in thru-hole or SMT mounting in vertical or horizontal orientations.
