[five processor analysis] TV box is the best chip configuration?

In this mobile phone, computers are all in the era of spelling. I do not know when the TV boxes commonly used in our homes are involved in this "nuclear" war! From the very first dual-core to the later quad-core, to the current eight-core, TV box manufacturers are always happy to refresh the product's "nuclear" number, always instiling users with high-nuclear-equivalent high experience. Shopping concept! The average consumer, who knows little about it, is also pleased to accept this so-called “fact”. What are the current mainstream chip makers in TV boxes? How do we choose the TV box that suits us? Today, we'll take a look at the "core" of the mainstream Internet STB in 2015 and take you to understand the mysteries!

Rockchip RK3368: 8-core 64-bit, Cortex-A53 architecture, clocked at 1.2GHz

Representative models: Taijie WEBOX WE30, cloud network CR18, mango å—¨ Q set-top box H7, Kaibol H9, etc.

Fuzhou Ruixin Micro's new processor, the RK3368, uses an ARM Cortex-A53 eight-core processor clocked at 1.2GHz and the GPU is the PowerVR G6110. At the beginning of the announcement, CNX-Software pointed out that compared to RK3288 and RK3188, A17 replaces A9 and Mali-T764 replaces Mali-400 MP4. The new flagship RK3368 is lower in power consumption than the previous generation, and can support the latest Android 5.1 system! Due to the higher purchase price, this chip is only used on a few TV boxes.

Hass K3V2: 4-core 64-bit memory bus, Cortex-A9 architecture, clocked at 1.5GHz

Representative models: Huawei secret box M321

Hass K3V2 is an authentic Chinese "core", independently developed by Huawei, and the industry's smallest quad-core A9 processor in 2012. With a high-performance CPU, the main frequency is divided into 1.2GHz and 1.5GHz. It is independently designed by Huawei. It uses an ARM architecture 40NM and a 64-bit memory bus, which is twice as high as the Tegra 3 memory bus. Due to the limited capacity of the various box manufacturers to optimize the chips, this chip is only present on the Huawei series of network set-top boxes.

Crystal morning Amlogic S812: 4-core 32-bit, Cortex-A9 architecture, clocked at 2.0GHz

Representative models: millet box enhanced version

Jing Chen's chip has always been the use of a large number of TV box ring chips, Cortex-A9 architecture and crystal morning excellent optimization capabilities, so that this chip in the box circle reputation, but the fly in the ointment is the chip's heating control, This is also a problem for users who bought TV boxes equipped with such chips. Game performance and video analytics are absolutely in the first echelon, which is why many popular box manufacturers are pursuing it.

Quan Zhi H8: 8-core 32-bit, Cortex-A7 architecture, clocked up to 2GHz

Representative models: Infinik I9

Quan Zhi H8 eight nuclear based on TSMC's latest leading 28-nanometer manufacturing process, uses eight ARM Cortex-A7 cores, supports 8-core 2.0GHz high-speed operation, and with Imagination's powerful PowerVR SGX544 image processing architecture, operating frequency up to 700M Around this, Quan Zhi's chip is often referred to as the “old eight cores” and is inferior to Rockchip RK3368 in performance. However, it is characterized by relatively stable performance, satisfactory performance, and higher cost than RK3368. Low, so many box manufacturers who like to stack hardware parameters like to use this chip!

Actions Force ATM 7029: 4-core 32-bit, Cortex-A7 architecture, clocked at 1.2GHz

Representative model: Tianmin T2

ATM7029 CPU is divided into 7 stalls, the lowest 252MHz, the highest 1.2GHz, in most cases the CPU will run around 1GHz. In the security Bunny software test, we found that it is indeed a processor using the ARMV7 instruction set, but in the nbench test the integral part of the score was only 3.584 points, far lower than the Coretex-A9 1.2GHz processor score of around 6.3 This can't help but make people wonder. This chip is only used in some domestic low-end box products, performance is also much worse than the aforementioned several chips.

The mainstream TV box chip we all see, in addition to Tai Jie WEBOX WE30 and Infinik I9 uses 8-core, the vast majority of boxes have adopted a 4-core chip, in the performance of Xiaobian also give you a ranking:

Rockchip Rk3368> Crystal morning Amlogic 812> Quan Zhi H8 ≥ Hass processor> Actions

Need to explain: It is not that the bigger the number, the stronger the performance. It depends on the core number, architecture, cache, and process performance.

In addition, we need to pay special attention to the 512M memory box that is still being sold. Xiaobian has had a tearful experience. The 512M memory box you want to use is really far-fetched. It is recommended that you select 1G memory and 4G or more flash memory. Box, but 1G memory is enough, flash memory, 4G online video is enough, if you see more local video, it is recommended to buy a box with memory expansion.

After introducing the TV box chip, I also hope that everyone will remember that buying a box should not be cheap or buy outdated flagship products. The TV box is not like a mobile phone, and the new generation will not be so fast. The average usage period of a good TV box is 3 to 5 years. Although the hardware parameters cannot represent the actual experience, with the richness of 3D and 4K video sources and the increasing software installation packages, strong hardware parameter support is very necessary! Do not want to eliminate the box in your hand for a short time and buy a high version of it!
