Detailed analysis of the MT8377 MT8389 MT6589 MT6577 Chip

MT8389 is a stranger to everyone, but if I say MT6589, I guess everyone understands it. In fact, MT8389 is a branch of MT6589, and a clone branch makes it clearer, is MT6589 high-consumption version. It can also be seen as the same CPU.

I think it is necessary to popularize the basic knowledge of MTK CPU before explaining MT8389, because the CPU development of MTK has a great continuity, for example, the smartphone chip contains the function mobile phone technology, and the function mobile phone chip integrates the genes of the smartphone, so we must trace the source before learning about the MTK new U, you can understand it thoroughly. Of course, you can ignore it. For new users, please refer:

Mtk cpu in the mobile field can be divided into three series:

1. MT62xx series:This series belongs to the functional mobile phone product line. It mainly uses three architectures, namely, ARMv5T, ARMv6L, and armarmarm911. These feature mobile phone chips are not weak and should be said to be very characteristic. Some performance specifications even operate the performance level of top-level smart machines in, such as MT6276. Some power-saving accomplishments alone in the world: such as MT6250, power consumption is only 1/10 of MT8389. At present, MTK's new Android smart chip is also widely used in the design of functional mobile phones.

Note: In the MT62xx series, the higher the CPU architecture, the higher the clock speed, and the better the mobile phone. The reason is very simple. Different functional mobile phones and smart phones, the pursuit is not simply performance, it is a combination of features, speed, price, and standby. Therefore, even the MTK's lowest-end function host has an all-around mentality. MTK can implement hardware with lower specifications, make a comprehensive machine. For example, the MT6250 of the ARM7 architecture, although the clock speed is only MHz, can be equipped with an intelligent Nucleus3.2.2 system on it to implement a fancy interface similar to that of a smart machine, similar to Android's smart software extension and feature-long standby of mobile phones, these features originally needed to be completed by the ARM11 processor. However, they can be achieved on the ARM7 platform. The benefits of using ARM7 are obvious, the chip licensing fee is low, the radiation is the lowest, and the power consumption is extremely low. representative model: Lenovo MA309. MTK also has some strength in the arm9-architecture. For example, MT6268 can process the high network throughput data and Wi-Fi data of China Unicom 3G at a frequency of 24 6 MHz, representing the model: lenovo I62, P717, pw.wg. The feature machine created by the MT6276 processor of ARM11 is almost the same as that of a smart machine. It can be used to expand software similar to a smart machine and provide a full 3D interface. The representative models include the Lenovo concept machine ZK990. The four-digit Catty is a feature of the MTK function mobile phone chip. The selling point of the MTK function mobile phone is not whether the hardware is powerful, but the system is dominant. The more features the system has, the more comprehensive the features the mobile phone is, the more accessories the hardware has become.

 

They do not pursue top-level performance, but they must be comprehensive. This feature has continued on the Smart platform. Friends who use MTK smart machines often find that their performance is not the strongest, on the contrary, the pursuit of detailed functions, such as ultra-long standby (power-saving), such as external connection capabilities (USB-OTG), naked eye 3D (Intel Graphics 3D display technology) and so on. MTK is very smart. While it ensures almost the same user experience as Qualcomm, that is, it pursues some additional functions while ensuring that the system is basically out of service and smooth, these inspirations are generally from function machines, because function machines are more pursuing functions and also pursuing functions on smart machines, which is a powerful manifestation of seeking for differentiated Android systems.

Taking the selling point of ultra-long standby as an example, Lenovo's main series of P phones are P70 (MT6573), P700 (MT6575), P700i (MT6577), and P770 (MT6577T) the entire series of P780 (MT6589) has been fully occupied by MTK, and Qualcomm has no foothold. Why? Because MTK has better additional functions than Qualcomm and saves power than Qualcomm. I would like to ask which of the following Lenovo's Qualcomm mobile phones have moved through the market with the selling point of ultra-long standby? No, at least none. Qualcomm is defeated in this additional function.

2. MT65xx series:This product line is currently the most popular mobile phone product line for MTK. MT65xx this series is generally used arm9, ARM11, Cortex-A7 and A9 architecture, ARMv5T, ARMv6L, ARMARMv7A instruction set, the reason is hot, because this is a link to the product line, as long as there is production, never waste.

For example, MT6516, the first generation of MTK Android platform in, was still in production in. Even inventory tail was useful. This year it changed its name to MT6255, what should I do if the MT6255 function is unavailable? Mediatek is very smart. He continues to take MT6516 and lower the frequency and price of the old chip. Then he changed his new name to MT6236, which became the latest technology and continued to sell, at the same time, I changed different interfaces on the system and changed the chip to update the system. This is an inheritance. Next, let me start. Do you know MT6577 and MT8377? MT6577 is used for mobile phones, while MT8377 is used for tablets. In fact, they are the same source. To put it bluntly, they are the same chip. MT8377 is a product slightly modified based on MT6577, which is essentially the same, for example, the Lenovo tablet A2207 has two versions: MT6577 and MT8377. The two versions of the system do not need to be modified at all, so they are similar.

MT65xx Series U is generally used to cater to the needs of the Android Market. In the Android Market, the systems of each vendor are similar and difficult to differentiate features, so currently, hardware is dominant. There are too many Android devices, selling points not only on the system functions, but also on the publicity effect. Why does MTK not use A8 or A5? Because they have no gimmicks in publicity and are only devalued, MTK is still able to make a fight against Qualcomm's army. It is like this: when Qualcomm uses the Scorpion architecture, MTK said Scorpion Architecture Based on Cortex-A8, without our A9 product is powerful, when Qualcomm uses Cortex-A5 products, MTK said that our production of Cortex-A7 products more powerful than A5. When Qualcomm adopted the Krait400 architecture product, although Krait400 Based on Cortex-A15, performance exceeds any of the current MTK, but MTK is still reserved, our A7 product is more power-saving. When the performance is strong, we are very powerful, performance is more powerful than others, we also want to say we are more power-saving. MTK can also reduce the price when power consumption also loses the selling point advantage, so MTK is unbeaten in any situation, because it does have a commendable skill.

3. MT83xx series:This series is used for tablets, the main products are MT8377 and MT8389, here I mainly talk about MT8389: MT8389 is not a Cortex-A9 architecture, A9 is some websites make misleading, it adopts the quad-core architecture of Cortex-A7, ARMv7A executes Instruction Set in sequence, uses 28nm LP process of TSMC, clock speed is 1209 MHz, supports 32bit single channel LPDDR2 class memory, and supports a maximum of 533 memory specifications. Someone on the network said it supports 64-bit dual-channel LPDDR3, which is wrong and purely fooled. GPU is a physical unit of PowerVR 544MP, with each 286MHz clock speed. It supports 3G network connectivity under the MT6167 baseband. If it works with the MT6168 baseband, it can implement the TD 3G network, the power consumption of the entire CPU is above mW. It supports up to million cameras, up to P resolution LCD output, and H.263H video decoding. 264 1080 p @ 30fps/40 Mbps video hard solution, the overall decoding capability is relatively strong, for hard decoding is a 480 MHz clock speed, Architecture for Cortex-R4 MCU, this is the first time that MTK has introduced the Cortex-R series processor into the CPU, so it is worth looking forward. The overall performance of MT6589 is equivalent to that of Tegra3. As a quad-core, it has mediocre performance. As a quad-core, it consumes reasonable power.

The MT8389 is similar to the MT8377 introduced earlier. It is modified by the CPU of the mobile phone, but the MT8389 is smaller than the MT8377. It can be said that it only needs to change the name, its original name is MT6589.

Some netizens may have to ask, since it is the same U, why should we change the name? The answer is: MT8389 is not applicable to mobile phones and has to be used on the tablet ...... Why is it not applicable to mobile phones? Answer :...... Let me explain it slowly.

The same CPU produced by the same factory, even if the process is the same, the architecture, instruction set, and clock speed are the same, but the power consumption and heat consumption of each CPU are different, this is like when the CPU on the computer is too frequently, it finds that the "Physical Constitution" is different. When the two CPUs of the same model are too frequently, there is a significant difference in the calorific value. Some have high voltage and some have low voltage, the frequency that can be exceeded is also different. When Intel is producing CPU, the U of different constitution produced on the same assembly line will end up with different models and be sold at different prices, good fitness is expensive, and poor fitness is cheap. Similarly, the difference between MT8389 and MT6589 lies in the "Physical Fitness" problem.

The power consumption of MT6589 is generally 500-700 mW at a GHz frequency. Because the 28nm LP process is not very mature and the yield rate is not high, there are often some products with excessive power consumption in the production process, these products generate more heat at the same voltage and consume more power at the same clock speed, which has exceeded the MW standard. These CPUs are superior power consumption products for mobile phones, but they are not inferior because they can be used and are suitable for tablets. There is a possibility of overheating in the limited space of the mobile phone, so these products have a new use, used in the tablet, renamed MT8389.

The flat panel is generally more than 7-inch, and the heat dissipation space is 3-4 times larger than that of the mobile phone. during design, as long as enough metal heat sink is added to the motherboard, the heat dissipation problem can be perfectly solved. As for power consumption, it is easier to solve than heat dissipation, that is, to increase the battery capacity. It is not difficult to increase the battery capacity of a tablet. The power consumption of MT8389 is naturally much larger than that of MT6589, but it is still very low compared with the quad-core with a power consumption of more than 1 Watt, such as Tegra3, APQ8064, and Exynos 4412.

MT8389 running the Android 4.2 system is still smooth. PowerVR 544MP GPUs can also ensure that all kinds of large-scale Android games are available. As for the single-channel or dual-channel storage problems, there is no need to worry too much about this. The effect of the storage speed on the MT8389 experience is negligible. Even if it is changed to a dual channel, it will not change much. According to the Barrel Principle, the biggest shortcoming of Android devices is not the CPU or RAM transfer rate, but the slowest ROM. The reason why MTK devices are cheap is that the ROM is relatively cheap and is basically in the initial e. at the MMC4.41 level, the transmission rate is around 22 Mbit/s. Therefore, loading time for Large Games using MTK devices is relatively slow, which has nothing to do with CPU and ROM. Why are intel devices expensive? For example, Lenovo K900, where the hardware cost of 2000 yuan is definitely the most expensive mobile phone in the market, and its ROM has reached e. the speed of MMC4.5, the transmission speed of 45 Mbit/s, can be said to kill everything in seconds, for example: Lenovo K900 and S920 (MT6589) Game data packets are universal, when they open a large game at the same time, the K900 loading speed is much faster than the S920, which is the power of ROM.

The biggest advantage of MT8389 tablet is its native support for calls and dual-card dual-waiting (except for devices discarded by manufacturers ). A phone tablet can be held on your hand, which can reduce the usage of mobile phones, which is more convenient.

Although MT8389 is cheap and has average performance, it is not impossible for tablet manufacturers to use it to create high-quality products. 1. The RAM capacity can be increased. We recommend that you upgrade to 2 gb ram (MT8389 supports a maximum of 2 gb ram). Although 2 gb ram does not necessarily increase the speed significantly compared with 1 gb ram, however, a larger runtime space can support more background software, which improves the user experience to a certain extent. 2. Adopt a ROM with a faster speed and a larger capacity. The ROM speed is crucial. If the ROM speed is faster, the whole flat speed will be significantly improved. The speed of the flat can be directly increased by switching the host, surfing the internet, and reading progress of the game, immediately add extra points to the user experience. A larger ROM is also necessary, because even if the android program is installed on the SD card, it will take up a certain amount of space in the ROM, and the less space available, the slower the speed. 3. This requires the cooperation of users to add a high-speed memory card to your tablet. The reason is mentioned in the second point.

The biggest highlight of MT8389 is the GPU. Its powerful GPU performance is comparable to the integrated graphics card level of mainstream laptops in. It can handle any mobile application currently, supports OpenGL ES 1.1/2.0 and OpenVG1.1 standards. The triangle filling rate is 50 M tri/sec, and the pixel filling rate is 572 M pixel/sec, between Tegra3 and Exynos 4412, for games, the most important thing is the triangle filling rate, 50 M tri/sec is relatively good. If you buy a tablet to play games, you can rest assured.

MT8389, as a cheap tablet of less than 1500 yuan, is still very cost-effective. At least two years can ensure that Software games can be used in general, and two years later, elimination is inevitable. MT8389 is not suitable for high-end products. Of course, I should first remind you that for hardware manufacturers, the processor is changing from 32-bit to 64-bit, the A57 + A53 architecture will completely eliminate A15 + A7 in three years. Therefore, no matter how well you buy an ARM tablet, you cannot be proud of it for many years, just like the android host of ARM11, software Installation is often incompatible, and A7 is also the same. If you want to buy a quad-core A7 tablet, buy it early and enjoy it early. If you don't buy it, don't buy it. Wait for the 64-bit processor.
