1. 1. The computing power of mobile phones now exceeds that of the Apollo spacecraft of the United States at that time
2. The computing power of desktop computers using mobile phones requires the support of hardware and software
3. If you are interested, you can study SETI's software and use computer computing resources all over the world to search for aliens

2. No, the CPU of a mobile phone is an embedded CPU. Its instruction set is simplified (that is, its function is simple). Although the speed is faster and faster, it is not the same concept as a computer. Or you can understand it from the aspect of energy (a computer uses so much electricity as a mobile phone, so what's the computer for.
3. It depends on how many vibrating motors there are in the vibrating ore drawing machine. It doesn't matter if there are only one
if there are two vibrating motors, there will be positive and negative rotation
if there are two vibrating motors, there will be positive and negative rotation
4. No problem. The computing power of the computers used in Apollo's lunar landing is not as good as that of today's mobile phones or even single chip microcomputers. The navigation computer used on Apollo has a dominant frequency of 2.048MHz, 2048 word ram and 36864 word Rom. now the dominant frequency of Casio calculator is 30MHz. The processing speed of the flight control computer on the space shuttle is only 0.4mips, less than one percent of that of Xbox. There is a popular science theme post in the website. Find it yourself. However, the instry has a specialty, as long as meet the requirements is good. For example, the last upgrade of the Hubble telescope was only upgraded to 586 level. The red flag 2 missile uses a bit machine (one bit single chip microcomputer, multiple combination functions).
5. 1. Look at the cost: the comparison between the two is not only to see the size, but to see the cost. A high-end mobile phone costs no less than a computer. The smaller the hardware, the higher the technology content, and the more R & D investment
2. Look at technology: the development of computers has been relatively mature. At the beginning, computers were very expensive, and they were all on W. think about how valuable the money was at that time. In addition to the fierce competition, the cost was almost transparent, and the profit was reced. The high-end mobile phone technology is in the hands of a few giants. Monopoly generates huge profits and is not afraid of no sales. Apple and Samsung are a typical example
3. Look at the consumer group: the pursuit of fashion and the psychology of keeping up with the Joneses urge young people to rush for these procts, which directly contributes to the prosperity of the instry. Price is no longer the first consideration. For example, the iPhone 5S now needs more than 1W to be inlaid with Phnom Penh, and there is no market for it. At present, apple is procing this kind of mobile phone, which is the so-called local tyrant mobile phone!

6. Do you mean the older CPU architecture and mobile phones on the desktop like the Qualcomm 820
7. Although mobile phones now have eight cores, they still can't match the processor of computers
8. Performance and energy are positively correlated with volume. Half of the desktop is laptop, and half of the notebook is mobile phone.
estimated by volume, it's 1 / 8 of the same price.
according to energy consumption, it's 1 / 10
estimated by volume, it's 1 / 8 of the same price.
according to energy consumption, it's 1 / 10
9. I don't think mobile phones and computers can be compared. Five years ago, 5000 price laptops can play lol. now, take the iPhone 6S with lol to see if it can drive the development
10. 1、 Architecture difference:
Architecture is only equivalent to the framework of a building, which is the most basic and extremely important part. PC uses complex instruction system (CISC), while arm uses reced instruction system (RISC). The same frequency CPU floating-point computing power is thousands to tens of thousands of times different< Second, process & main frequency:
the CPU's operation speed depends on the comprehensive index of CPU, including cache, instruction set, CPU bits and other factors. Under the same main frequency, the computing power of computer CPU is tens to hundreds of times higher than that of mobile CPU
Third, the impact of core:
mobile multi-core should be called multi CPU, which encapsulates multiple CPU chips to deal with different things. PC multi-core processor refers to the integration of multiple computing cores on a processor, which can deal with the same thing through mutual cooperation< 4. GPU core:
