The most thing in computer and mobile phone understands more easily, but the core to the system -- processor (CPU) , to a lot of people, it is it seems that unfamiliar and cannot touch. As technical day profit grows, no matter be mobile phone processor or computer processor,had arrived when property is surplus. We are very much the person often hears Cpu of 8 nucleuses mobile phone, cpu of jotter double nucleus, 4 nucleuses, even frequency of processor of mobile phone of in some way wants prep above Cpu of a few computer, and this moment a lot of netizens think even mobile phone processor already very strong, 8 nucleuses Cpu compares the processor of double nucleus Cpu of computer to still be close friends, but is the fact such, let us solve those doubt in your heart today. Actually from at present angle looks, mobile phone Cpu and computer Cpu are comparative, differring actually still is very big, why, we look step by step!
One, the framework is different, bring about function to differ
CPU basically is in charge of explaining computer instruction and the data in handling computer software. The main trend of mobile phone CPU that we use now is ARM framework, and the framework that personal computer CPU is X86. CPU framework is equivalent to an architectural frame only, decided the basic structure of a CPU at the beginning, it is the basiccest, the most important part. What at present computer CPU uses is CISC of complex instruction system, and mobile phone CPU advocate those who hit is power comsumption low, cheap, those who use is RISC of compact instruction system, its operation ability greatly the operation ability under computer CPU, ability of operation of floating-point of coequal frequency CPU differs in thousands of to on 10 thousand times, if you see there is the processor property of some mobile phone on the net,rival computer processor so, basically be exaggerate, relative perhaps it is the computer CPU more than 10 years ago.
Perhaps someone can say certainly, that why mobile phone CPU also does not use the framework such as X86, really Intel Ceng Jin has tried, the CPU of the mobile phone must satisfy power comsumption low, cheap, and the framework CPU such as X86 satisfies this very hard on function and power comsumption really.
2, power comsumption is different
We had said above, framework of mobile phone CPU is simple, advocate hit power comsumption low, computer CPU is relatively complex. But compare with computer CPU photograph, this is both in power comsumption respect it is relative without method, not be the thing of a level more. The processor of computer is the power comsumption of a few tile of 15-120, and how much is the power comsumption of mobile phone processor, at present Cpu is fully loaded with the strongest mobile phone to also be less than 1w, more what is more,the rather that hand CPU is compositive still other something, because this is for energy changeover level,this both can not compare a gender.
3, advocate frequency
Cpu advocate frequency is clock frequency, show the rate of concussion of signal of pulse of the number inside CPU, with CPU practical operation capacity is put in particular concern, but did not concern directly, the integral performance index that decides the operation speed of CPU sees CPU each side even (collect of cache, instruction, the element such as the digit of CPU) . Of framework of parameter of mobile phone Cpu different those who decided rate is different, identical advocate the operation ability that Cpu of the computer below frequency wants to compare mobile phone Cpu is tall a few to hundreds of times. Same computer uses 64 CPU now, photograph comparing has Arm32 should a lot of faster, do not see what connect 855 2.84GHz high to compare 1.5GHz of jotter low pressure certainly is good so.
4, core
Up-to-date we still have Cpu of a lot of computer is double nucleus or of 4 nucleuses (small nevertheless make up must plaint to also appear personal computer is at present highestly 16 core even 32 core) , and mobile phone processor has stridden 8 core for the most part. We know, below coequal condition, CPU core number is more performance is stronger also, but this view also does not hold water, at least the core of the core of mobile phone Cpu and computer Cpu still has substaintial distinction. Say with straightaway word, the much nucleus of computer is handled even if cooperate each other, mutual cooperation processing is same a thing, collateral run. And much core of mobile phone Cpu is " sizy core " , forcibly many CPU sticky together, in the basis the function differs, the core that uses actually may have 1 to go to 2 only, of the others can not fight side-by-side. Much core of CPU of another mobile phone is divisional and high frequency of the cent with low frequency, likelihood the frequency of 1-2 is 2.8Ghz, the rest frequency may be very low very low, and computer is different, each core of computer Cpu is high-frequency. Because this function also is not of a level absolutely.
5, craft
Mobile phone CPU and computer Cpu are before on craft still is distinguishing, but, these are already nonexistent now difference, mobile phone CPU and computer CPU had been been in same a level, at present the stage accumulates electric generation to be versed in there is ARM processor already in manufacturing 7nm, also have X86 computer processor, so craft difference is not very big.
Finally, I am small making up those who want to say is this is actually both be can not compare a gender, they are not the thing of a level, the most important is them also do not move below an environment, if must define computer to be able to say,be productivity tool, and the mobile phone is tool of a recreation at most, if put these two kinds of processor below an environment to move, what processor of that undoubted mobile phone will be killed by the second is very miserable (estimate tall Tong Xiaolong 855 also gallop at most N4200, the level of the J3455 that surpass raise) . Of course, arm framework processor also tries to infiltrate Cpu all the time Windows system, and Intel also is trying to cut a structure to produce mobile phone CPU with X86 all the time, future perhaps one day, both may move below a system, bad of what actor what, static wait for trenchant.
Small nevertheless make up most the returning that expect is one day homebred computer CPU can enter the world advanced, do not know you are raised do not support!
