support multi CPU parallel processing: because the server has a large amount of data processing, it needs to adopt multi CPU parallel processing structure, that is, 2, 4, 8 CPUs are installed in one server. In order to achieve this goal, it needs to be considered and supported in the design of cup. The CPU of ordinary desktop computer generally does not have such conditions. It should be noted that the number of CPUs required for parallel architecture must be even
2. Powerful processing power: it is much higher than ordinary CPU in processing speed and multitasking performance. Compared with ordinary CPU, its core type, pipeline architecture, instruction set, interface pin number and so on are not the same, and it uses a large capacity of two or even three-level cache to improve the data hit rate
3. Extremely high stability and reliability: because most high-performance servers have to meet the full load requirements of 365 days a year and 24 hours a day, the stability and reliability are far beyond the ordinary desktop CPU.

hyper threading technology is basically to explore the full performance of hardware. For various reasons (such as CPU design, software support, etc.), although you can see that the CPU is full, a considerable part of the CPU is still idle. Hyper threading technology enables single core CPU to simulate al core CPU by adding special hardware instructions and logic processing units to the CPU hardware, Rece idle, improve efficiency. The status of two threads is naturally equal, and there is no difference between them.
now, regardless of the impact of CPU design on performance, let's just talk about it. For a single core CPU, suppose it processes 10 times per second, one instruction per time, and 10 instructions per second. If it has two threads, it can process 2 instructions per time, and 20 instructions per second, So theoretically, the performance of al core and single core al thread is the same. But in fact, it is very difficult to do this, because the real physical core is exclusive resources, while the logical core is shared resources. When a resource is used, other threads using the resource can only be forced to pause. At this time, there is no difference between al core simulation and single core simulation. It is undeniable that resources will not always conflict, most of the time it is still effective, and this design only needs to expand the CPU area by 5% and a very small amount of power consumption
as early as the pentuim4 era, hyper threading technology has been applied. The data show that the performance of P4 can be improved by 15% ~ 30% after using this technology. Now, it should be much better. The premise of hyper threading is: a CPU supporting hyper threading technology, Windows XP pro or later operating system, application software support for the technology
for the choice of fx8350, i5 3470 and i7 4770, just look at the price. Do you think you will buy a CPU with high price but low performance? High end direct i7 4770. Do not choose i5 because i5 is one grade lower than i7; If you don't choose FX, the performance of the single core is so poor that it doesn't match the capability of the flagship at all. Even the last generation of elong can't match it. As a result, its eight cores, that is, the level of i5, and its price is the same as that of i5
you can check the evaluation of e31230 V2 and i53570k to find out whether the hyper threading technology affects the CPU; Check the evaluation of i5 3570k and FX 8350 to find out how poor the single core performance of FX series is, and then make a decision
pi software to measure the performance of single core (recommended high frequency IU)
i5

first determine the configuration you want, how you need to configure a computer, whether it is a game or a job, and the price you want
2 / 8
after determining your price, I'm a performance party, and I don't have high requirements for appearance, so I spend most of my budget on graphics card and CPU
3 / 8
CPU. Generally, I buy the new flagship Intel of this year. If the price is more than 1600 yuan, I'll be able to refer to 6700k loose film or choose the previous generation with higher performance. If I have special needs, I suggest purchasing Zhiqiang series E3, E5 Level 3 cache and computing power are stronger. Then select the motherboard according to the number of pins in your CPU

if the budget is average, gtx960 can run super smoothly, watch lol and other games. If you like overclocking, you can buy a card R7 and R9 series, but I don't think the effect is very good. Although I'm a card fan, if I want to buy a better rx480, gtx980ti, 1070 and rx490, 2000-4000 or so graphics cards are enough, I don't recommend buying 1080 and other graphics cards. The extra 1000 yuan can make your next purchase of graphics cards more frequent, which can maintain the high-end computer performance

in fact, 16g DDR4 is enough. If you have the conditions, you can set up a 32g al channel and basically take it all

those with strong cooling ability can choose water cooling. You must choose a good chassis to support the length, width and height of your cooling plate 120.240.360 water cooling, weaker can choose air cooling, remember not to buy too cheap radiator, at least 100 yuan, otherwise it will cause hardware damage
7 / 8
the choice of power supply is very important. First, Taobao has many power supplies for virtual meters. It is recommended to buy regular brands

hard disk anyway, I plan to buy a 250g solid-state hard disk with high transmission speed, and then buy a 2T mechanical hard disk with enough transmission speed.
Apple x is still very good and worth buying
iPhone x is a high-end model. It adopts a new design, equipped with a sharp color OLED screen and an upgraded camera. It can use 3D face ID sensor to unlock the phone and support airpower wireless charging
the iPhone x screen is an excellent screen of the iPhone series, which supports 3D touch pressure sensing operation and HDR display. IPhone x uses face ID for face recognition. In addition to the traditional light and distance sensor, the forehead integrates a 7 megapixel camera, floodlight sensor, distance sensor, dot matrix projector, infrared lens and dot matrix reader
the a11 bionic processor on iPhone x adds support from artificial intelligence, neural network and AR, and is equipped with an ISP independently designed by apple, which improves photography. It is the most powerful processor of apple before the release of iPhone X
the screen size is 5.8 inches, the weight is 174 grams, the height is 143.6 mm, the width and thickness are 70.9 mm and 7.7 mm respectively, the resolution is 2436 * 1125 pixels, and the resolution is 458 PPI
