Proportion of S9 computing power

Ant mining machine S9 how much a day to dig

S9 computing power 13.5T, the current network computing power 6.39eh/s, 1e = 1024p, 1p = 1024t, 1t = 1024g, a S9 a day to proce bitcoin is [13.5 / (6.39 * 1024 * 1024)] * 180 ≈ 0.0036btc< br />

2. Bitcoin, in short, is an internationally recognized virtual currency. In some foreign countries, bitcoin can be used to trade; In China, it was also announced a while ago that bitcoin withdrawal might be tried out
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it
mining is definitely the first professional mining machine. Many new children's shoes will choose to mine with graphics card. However, mining with graphics card is just like doing a professional job with "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

4. S9 screen is 5.8 inches (right angle) / 5.6 inches (rounded), 18.5:9 full view curved screen.

5. The main differences between S8 and S9 are as follows: 1. Different CPU processors: S8 is a 2.35ghz, 1.9GHz eight core processor; S9 is a 2.8GhZ, 1.7GHz 8-core processor. 2. Different volume: the volume of S8 is 148.9 x 68.1 x 8mm and the weight is 155g; S9 has a volume of 147.7 x 68.7 x 8.5mm and a weight of 163g. 3. The aperture of the camera is different: the aperture of the front and rear cameras of S8 is f1.7; S9 rear camera f1.5 / F2.4 aperture, front camera f1.7 aperture. 4. In addition, S9 also supports coagulation time shooting, dynamic shooting and intelligent scanning unlocking.

Samsung S8 and S9 are not the same size. The Samsung Galaxy S8 is 148.9mm long, 68.1mm wide and 8mm thick. Samsung's Galaxy S9 is 147.7mm long, 68.7mm wide and 8.5mm thick

in addition, the screen proportion of Samsung S8 is 84.2%, and that of Samsung S9 is 84.15%; The CPU model of Samsung S8 is Qualcomm snapdragon 835, and the CPU model of Samsung S9 is Qualcomm snapdragon 845

features of Samsung S9:

1, AR mapping

this function is similar to the animoji of iPhone X. users can generate interesting ar mapping with the help of front camera, and add different hairstyles, costumes and bbing to AR mapping to make a unique expression pack

2, al speakers

Samsung S9 is equipped with al speakers with AKG in charge of tuning. It also supports Dolby atmos Dolby stereo and 32bit music playback. The official also said that the external volume of S9 is 140% higher than that of S8

3, hybrid face unlocking

Samsung S9 supports face recognition and iris recognition at the same time, but the use scenarios of both are limited, so Samsung made a decision to automatically help users switch the unlocking scheme. Specifically, in the case of sufficient light, the phone will choose the face unlocking scheme, and when the light is insufficient, it will use iris recognition to unlock

7. For the specifications of Samsung S9 mobile phone, please refer to the following contents: 1. Screen: 5.8 inches (right angle) / 5.6 inches (rounded corner), 18.5:9 full view curved screen. 2. Size (height * width * thickness): 147.7 x 68.7 x 8.5mm, weight 163g. 3. Shell color: Enigma night black, Rhine blue, Xiwu purple (subject to the actual sales). 4. Memory: the total ROM memory is 64GB / 128GB; The total ram is 4GB. 5. CPU (processor): 2.8GhZ, 1.7GHz snapdragon 845 eight core processor. 6. Camera: the rear camera is full pixel al aperture 12 million pixels (f1.5 / F2.4), supporting OIS optical anti shake; The front camera is 8 megapixels (f1.7 aperture). 7. USB type-C interface is adopted. 8. The battery capacity is 3000mAh. The main highlights of S9 are as follows: 1. Freezing time shooting: ultra high speed sensors capture the moment with an amazing 960 frames per second, so that the wonderful is no longer fleeting. 2. Intelligent variable aperture: f1.5/f2.4 al aperture mode, classified variable aperture, which can automatically adapt to strong light and ultra-low light environment like human eyes. So that the shooting is no longer troubled by the light environment. 3. Dynamic shooting: create an animated version of yourself, and generate your own emoticons with different actions and expressions. At the same time, dynamic cute video can make you become an animation star by recognizing facial expressions and actions, and then refuse to chat. 4. Bixby vision: just turn on the camera to take a picture and call up Bixby vision to display the information you want to know. Restaurants, fitness, shopping... Farewell to lost. 5. Intelligent scanning: it combines the speed of face recognition with the accuracy of iris recognition. When unlocking the screen, intelligent scanning can judge the light conditions by itself, and select face or iris to unlock, making your use more convenient.
