Seeing this Honghu 8 18, Bian Xiao's first thought was "This is half a Hayes Kirin 970"! Of course, Hisilicon Kirin 970 does not need such a powerful "coprocessor" as Honghu 8 18 in video decoding and sound quality optimization. The TV chip does not need the "baseband chip" of Hayes Kirin series.
There is no clear information about the manufacturing process and architecture of Honghu 8 18. However, two A73CPU cores still make Dapingjun look forward to the performance of this product: although it will not be the top performance, I am afraid that the running speed in the mid-end market will have relatively good results.
Advantages and disadvantages of Honghu 8 18
For the CPU in the color TV industry, Big Screen Jun has always "scoffed". At present, the standard of mainstream products is that Cortex A53 and Cortex-A 17-Cortex A53 are products listed on 20 14, which are not outdated, at least they cannot represent performance standards. The reason why it is still in use now is nothing more than the advantages of cheap patent fee, small size and power saving. Cortex-A 17 is a product released on 20 14, which is mainly to "save power" instead of improving performance on the basis of A 15.
So the traditional intelligent CPU of color TV seems to give people a feeling that "power saving" is more important than "performance". And these CPUs are also used in relatively high-end products. For example, Xiaomi's 65-inch mural TV with a price of 6999 is the quad-core Cortex A53.
If the TV is regarded as a computing device, the CPU of the TV is obviously not fashionable enough: Dapingjun noticed that most of the flagship chips of mobile phones on the market now have four A76 cores-the next generation of products next year may have four A77 cores. Mobile phone chips are almost step by step with the progress of ARM. At the same time, CPU, which is ahead of PC in production technology, gives priority to the latest technology. For example, Huawei Hisilicon Kirin already has two 7nm chips.
In fact, TV chips have lagged behind mobile phone products for a long time, which is the biggest product difference among the "two smart consumer goods". Honghu 8 18 doesn't use the latest A76 core, but the two A73 cores are already very powerful. It can be seen that Huawei's understanding of color TV computing power is characteristic: it needs a certain single-core performance; The 8-core design is not adopted, which shows that Huawei thinks that the multi-tasking of color TV is not as good as that of mobile phone.
