Computing power of rk3399 CPU

2. The Ruixin micro rk3399 has been greatly optimized for integer, floating point, memory and other aspects, making the processor revolutionary in all aspects.

3. Rk3399 integrates a new generation of arm high-end image processor Mali-T860@MP4 GPU integrates more bandwidth compression technologies, such as intelligent overlay, ASTC, local pixel storage, and supports more graphics and computing interfaces.

4. His family now seems to have only rk3399 core board, but the development board should not be far away from it. In terms of performance, this core board adopts six core 64 bit arm processor, large and small core structure, al core cortex-a72 (up to 1.8GHz) + four core cortex-a53 (up to 1.4GHz), built-in low-power mcucortex-m0, four core mali-t860gpu, supports es1.1/2.0/3.0/3.1, OpenGL, openvg11.1, OpenCL and Dx11, supports AFBC (frame buffer compression), and has rich interfaces.

5. Professional questions may be:

1. Large chips (such as CPUs) have billions of transistors. If the transistors have manufacturing defects, the chip will certainly make mistakes. How to ensure that they are not damaged< Large chips (such as CPUs) have billions of transistors and can execute billions of instructions per second; Any error may affect the correctness of the program. I would like to ask why it can resist many environmental disturbances such as voltage fluctuation and achieve 7x24 hour reliability (7x24 hour refers to continuous service without a second rest, 24 hours a day, seven days a week)

there are different answers to these two questions

the first question is about the reliability of hardware proction

this reliability depends on the collaborative efforts of many aspects

first, we need to purify silicon. The purer the silicon wafer is, the less interference of impurities will be

general semiconctor devices, such as the triode used in your old radio, require more than 99.9999% high-purity silicon (6 9S); Large scale integrated circuits need at least 99.999999% high purity silicon (9 9S); Computer chips such as CPU need more than 99.999% high purity silicon (11 9S); The purity of the purest silicon material that human beings can make at present can reach 12 9

in other words, silicon wafers are so pure that only one other atom is allowed in the 100 billion silicon atoms used for CPU proction.

6. The processor of m330 box is Hisilicon hi3798m. This processor adopts a four core A7 architecture with a maximum of 1.5GHz, integrates mali450mp4 GPU, and supports multiple formats of encoding and decoding and expansion interfaces, including 4K VP9 and h265 decoding
Ruixin micro rk3399 processor adopts al core A72 with four core A53, a total of six core design, the highest frequency is 1.8GHz, integrated with mali-t864 GPU, and supports mainstream format encoding and decoding and expansion interface, including 4K VP9 and h265 decoding
in terms of performance, Hisilicon hi3798m is not the rival of Ruixin micro rk3399. For example, the hi3798m has no high-performance core, and is inferior in terms of core number and core frequency. There is also a significant gap in the integrated GPU core architecture
considering comprehensively, it is not recommended to purchase this proct in 2019.

7. Board performance is good, there are more complete information and tutorial reference, you can go to their official website to understand ah

8.

In terms of performance, Ruixin micro rk3399 CPU adopts big. Little architecture, al core cortex-a72 and four core cortex-a53

Ruixin micro rk3288 is based on 28nm HKMG process, and the processor adopts four core arm cortex-a17, with the main frequency of 1.8GHz. The DDR controller is designed with al channel 64bits DDR3 / ddr3l / lpddr2. Rk3399 for high-end, rk3288 for high-end. The positioning of Ruixin micro is different< br />

9. In terms of performance, vs-rk3399 CPU adopts big. Little architecture, al core cortex-a72 and four core cortex-a53<

vs-rk3288 is based on 28nm HKMG process. The processor adopts four core arm cortex-a17, and the main frequency reaches 1.8GHz. The DDR controller is designed with al channel 64bits DDR3 / ddr3l / lpddr2. Rk3399 for high-end, rk3288 for high-end. So the positioning of the two is different
