Cost performance of graphics card
The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance
Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy itsummary:
to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted
So Xiaobian's opinions and suggestions are as follows:the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test
as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards

Nursing workers are employed in the hospital for patients or their families to assist nurses in daily nursing and help patients. Compared with ordinary nannies, nursing workers have more professional nursing knowledge and skills, and can provide professional rehabilitation nursing for postoperative patients, vegetative patients, paralyzed patients and so on. So, what are the requirements of being a nurse? What is the specific work content of the nurse
I. what is a nursing worker

American option refers to the option that can be executed on any day after the transaction. That is to say, the option holder can choose to execute or not to execute the option contract before 9:30 a.m. New York time on any working day before the expiration date of the option
American options allow the option holder to exercise the right to purchase (if it is a call option) or sell (if it is a put option) the underlying assets on or before the maturity date.
there are usually two ways to exercise foreign exchange options in the world: one is American options, the other is European options
American options refer to the options that can be executed on any day within the effective period after the transaction, which are mostly adopted by floor exchanges
for example: the spot exchange rate of euro / US dollar this morning is 1.1500, and a customer expects that the exchange rate of euro may rise to 1.1600 or higher in the evening or tomorrow. So he bought an American option with a face value of 100000 euros for two weeks, with an exercise price of 1.1500 euros and a put on the US dollar. The rate was set at 2.5% (i.e. the option cost 2500 euros). The next day, the euro / dollar exchange rate rose, and exceeded 1.1500 to 1.1700. Then, the client can ask to exercise the option immediately (1.1700-1.1500 = 200) and make a profit of 200 points, or $2000. But after decting the cost of the call option, the customer still lost $875 (2000-2500) × 1500 = - 875 US dollars). It can be seen that although American options are more flexible and convenient, the cost of option fee is very expensive
the English Chinese Dictionary of securities investment published by the commercial press explains that American option is American option; American-style option A form of option contract. The holder of the contract may make delivery at any time from the purchase date to the maturity date. The liquidation shall be carried out according to the e performance price. The corresponding is European option
the difference between American options and European options
the difference between them is mainly in the execution time
(1) American option contracts can be executed at any time before or on the maturity date, and the settlement date is one or two days after the performance date. Most American option contracts allow the holder to perform at any time between the trading date and the performance date, but there are also some contracts that require a relatively short period of time, such as "two weeks before the maturity date"
(2) the European option contract requires the holder to perform the contract only on the e date, and the settlement date is one or two days after the performance. At present, European option contract is used in foreign exchange option trading in China
because American options have more leeway than European options, American options usually have higher value. Most options traded in the United States are American. However, foreign exchange options and some stock index options are obvious exceptions. Therefore, American option is more flexible than European option, which gives the buyer more choices, while the seller is always faced with the risk of performance. Therefore, the premium of American option is relatively high.
