Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
as a middle-aged miner for 13 years, let's talk about the feeling of mining before.
I bought four mining machines in the past. bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.
the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.
the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.
generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.
when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha
now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.
mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.
finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine
built in 1600 stream processors
pay attention to the number of stream processors in mining
and this graphics card is very affordable now
in a few months, the miner will come out
Yes , on August 21, Beijing time, recently, TSMC officially announced that the 7Nm chips, which were put into large-scale proction in 2018, have now proced more than 1 billion 7Nm chips. At the same time, more than 100 procts began to use the 7Nm chips proced by TSMC
it is understood that TSMC's first 7Nm chip started large-scale proction in April 2018. Meanwhile, the billionth 7Nm chip was proced in July this year. In these 27 months, TSMC has to proce more than 37 million 7Nm chips every month
according to the data, the first batch of TSMC 7Nm procts include bitmainland's miner chips, Xilinx's FPGA chips, apple A12, Huawei's Kirin 980, etc
