mining machine risk

1. The problem of electricity charge

in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

2. Hardware expenditure

mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

3, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2. Add a little bit to the upstairs answer
now the mainstream games are inclined to n card for game optimization
now the main problem is that a card has not solved the problem of PhysX
if it is finished, I believe it will be inclined to a card for optimization
after all, it is more cost-effective, and the more people buy it
3. Graphics card a card and N card:
a refers to ATI
one graphics card manufacturer
n refers to NVIDIA
another graphics card manufacturer
the two largest graphics card manufacturers proce graphics card chips
usually the so-called a card refers to the graphics card using ATI graphics card chips, such as 9550 ah, x1600 and so on
n card is the graphics card using NVIDIA graphics card chips, such as 7600gt ah, 6600le
I feel that it has almost the same relationship with AMD and Intel
at present, ATI has been acquired by AMD
4. In terms of games, both a card and N card are suitable for playing games, but the driver of a card is not as good as that of N card in terms of all aspects of game support. General large game development companies have done some optimization work for the N card graphics card of the developed games, so n card will be better in terms of pictures and special effects (it may not be seen by the naked eye)
in terms of HD, card a has some advantages. When playing HD, the CPU occupancy rate is significantly lower than that of card n (not necessarily applicable to low, medium and high-end graphics cards). However, these are all the conclusions drawn from software testing. When watching HD, ordinary users can hardly feel the harm of using more CPU. After all, they are all al core, three core and four core now
to play StarCraft 2, it is recommended to buy n card (the first choice for gamers)
of course, in terms of cost performance, a card is also suitable for purchase, and there are still some price advantages of a card
of course, there are many versions:
1,
there is no difference, from the core architecture to the board wiring are very similar, the only difference is the way of multilateral computing, who is more advanced forget, but in actual use can not see the difference, performance can be measured by price, no matter which party has to admit that their low price can not compete with their competitors' high price, In general, the performance of the graphics card is mainly reflected in the number of polygons. The more the number of polygons, the higher the number of frames in the game. To a certain extent, you can even sacrifice part of the polygon (number of frames) in exchange for the opening of special effects. In the final analysis, expensive performance is good, and you can perform more stably in the number of games. It's a helpless move of poor performance to take the cost-effective route
before the game was launched, some friends knew that it was almost 10%
the game will not really meet the players until it has been tested for a long time, including the performance of all kinds of hardware. EA top 10 is an example. The players say that nv7 does not achieve the actual performance in the game, so EA will release a patch the next day. No third-party manufacturer ever dares to give up another hardware for one hardware optimization, Blizzard also dare not and is unlikely to give up 70% of the global n-card users, which is not in the interests of developers. PC is an open platform, not a home game console
2. N card is easy to take care of, compact, and the driver is updated quickly. There are not so many bugs. The compatibility is better than a card
a card is a little troublesome to install the driver. Different versions vary greatly. Some are suitable for games, and some are suitable for watching HD
it's a little cheaper, and it's suitable to buy it back.
there's not much difference between the two in performance and price. There's a little difference in high-end evaluation scores, and there's no difference in playing games.
many n-rice or a-rice just use a certain proct of their period, and then they have a fixed impression on this brand
the tnt2 geforce256 ti200 7600gt and 9800gt used by N card, and the 9550 x700 1650gt hd3200 used by a card. Along the way, the game compatibility of a card is really not as good as that of N card
3,
the so-called a card usually refers to the graphics card with ATI graphics chip, such as 9550, x1600, etc
n card is a graphics card that uses NVIDIA graphics chip, such as 7600gt, 6600le and so on
the relationship between ATI and NVIDIA is similar to that between AMD and Intel. They are both leaders in the same instry and compete with each other. However, ATI is being acquired by AMD
n card works include geforce Ti series, geforce FX series, etc., and a card works include radium
x series
n card and a card focus on 3D performance and speed, while a card focuses on 2D image quality
n-card chips include GT, GS and so on. What's the difference? We don't know about legs. We only know that GS is the main proct in this series
GT is a higher level than GS, which is the high-end of the series, a bit like GT in cars
GTX is the high end of the high end, which can be generally understood as GT extreme
Le is a simplified version, which should be limited edition
TC, short for turbo cache, is a technology of NVIDIA, which enables the independent graphics card to share memory as video memory
another is ultra, which represents the highest end before GF7 series, but the name of the highest end of 7 series is changed to GTX
when a graphics card chip comes out, it is called public version. In order to occupy the market of various prices, it will increase or decrease its frequency, and then it will be sold as a new proct. The suffix of the graphics card is the explanation of its frequency. GT super frequency version, GS down frequency version and nothing are public version. X1950 is the core model of a card
the meaning of GT there are many similarities between the naming method of NVIDIA graphics card and F1 racing car. GT itself means high-performance sports car, and GTX means super sports car. I believe NVIDIA would like its graphics card to be as good as a sports car
generally speaking, the most high-end version of each series of NVIDIA graphics cards is suffixed with ultra
GTX means super version, ultra means supreme version and GS means enhanced version
from the perspective of graphics card, GS refers to high-definition version and GT refers to enhanced version
in terms of performance, gt of the same model is much better than GS
in addition to GS and GT, other models include Le, Ge, GTS, GTX and ATI's pro, XT, XTX, etc
Le: downconversion version Ge: Video HD game version GTS: Super enhanced version GTX: Ultimate (flagship) pro: Super enhanced version XT: Super enhanced version XTX: Ultimate (flagship) a card and N card model ranking from low to high in terms of performance
n card: le-gs-ge-gt-gts-gtxa card: gt-pro-xt-xtx
in addition: what's the difference between NVIDIA graphics card and ATI graphics card...
a card's picture rendering is better (intuitive feeling picture is better than n card, n card and a card's picture is darker than a card)
n card's game playing speed is faster than a card's (many games are optimized for n card),
in addition, the driver of N card is more mature than that of a card
generally, one SP of N card is equal to four of a card
although the specification of a card is often much higher than that of N card, the failure of the driver leads to the failure of a card to give full play to the performance of a card
because the SP frequency of N card is twice of the core frequency, while the SP frequency of ATI graphics card is equal to the core frequency
of course, NVIDIA graphics card
in these two kinds of graphics cards:
NVIDIA graphics card is higher than ATI's same grade graphics card for games
but ATI graphics card is slightly higher than NVIDIA's same grade graphics card in video and audio
if you use games, it is recommended to use NVIDIA graphics card
n card has high-grade
a card also has
but a card has heard that the movie effect is very good
n card game is good
start from the installation, The installation of NVIDIA drivers is much simpler and more convenient, and ATI's trouble is that if you want to install the control center, you must first install a framework, or the control center can't be used, and if you install the Chinese driver, you can also get a score to wear, that is, first install the pure driver, and then install the Chinese control center. Fortunately, vitsa improves this point, and the installation is humanized
ease of use is the key. First of all, if you're a novice, it's better to choose Ait. If you install a driver, you don't need to adjust anything. However, NVIDIA is more worried. After installing the driver, the resolution is maintained at 640 * 480 and the refresh rate of the display is maintained at 60. LCD has no CRT trouble, It needs to be manually adjusted to 85Hz, so it's very common that it doesn't adjust very much. In CRT, it's always 60Hz. In this aspect, ATI is much better. After the driver is installed, it will automatically detect the display and help to set the resolution and refresh rate. Then, in vertical synchronization, NVIDIA's default is that all games are controlled by application programs. When playing D3D and new games, the game can be set. Generally, there's no problem, However, some games without this setting, such as CS, are depressed. FPS always follows the display at 60Hz, and ATI's vertical synchronization takes this into consideration. By default, D3D games are controlled by programs, while OpenGL games remain off, and CS can maintain the highest 100fps
in terms of advanced settings, NVIDIA's interface is much better. The premise is to use the classic panel. We all know that the 9 series driver has added a new panel, which is slow to start and cumbersome to set. It is recommended that you use the previous classic panel and open all the hidden options of the panel with software or tools. This is very important because there are two key settings, For the options of overclocking and fixed refresh rate, NVIDIA can significantly overclock the graphics card through the driver, while ATI can only slightly exceed 10%. Another option is the fixed refresh rate option, that is, the refresh rate overclocking setting can fix the refresh rate of each resolution, which is very useful for CRT. ATI driver has greatly improved after upgrading to 7.2, The main change is to change the previous rendant 3D dynamic setting to more intuitive static setting. The disadvantage is that the overclocking setting is too stingy, which can only exceed 10%. The overclocking of the first mate can only be achieved through third-party software or tools
I have to mention multimedia. There are still many people watching HDTV. In terms of driver settings, ATI is much better. Avivo is directly integrated into the driver, which is very simple and clear. NVIDIA also has to install purevideo itself, which is not free. However, NVIDIA driver also has the advantage of setting its own resolution, which is very useful for connecting a computer to an LCD TV, As we all know, the best resolution of many LCD TVs is 1366 * 768. To achieve point-to-point resolution, it is necessary. The driver of NVIDIA can forcibly set this unconventional resolution, and the user-defined resolution of ATI is much worse, which can only be achieved through third-party software
the most important thing is compatibility. The two drivers are good, and there is basically no compatibility problem. Even if there is a driver that can be updated soon, ATI is still commendable. It is basically updated once a month, but NVIDIA is not so good. The official driver update is always very slow, After 93.71, there are no updated official drivers under GF7, and the vitsa driver is a step slower than ATI's. I hope NVIDIA will not forget to enhance the perfection of its driver while strengthening its proct line
generally speaking, I just like them. They are different types of things, but they are OK, but they can't be mixed.
5. A card should be used for graphics, because a card has high brightness and sharpness. However, a card has poor compatibility with the game, and its potential is higher than that of N card. In terms of overclocking, it is obviously much stronger than that of N card. However, many a card manufacturers have limited overclocking. A card likes to have a splash screen, a black screen and other problems when playing games. In terms of driving, a card has always been the most shameful

and N card is very good in the game performance, compatibility is very good, but the color is too cold, dark, brightness is not high. (a card and N card I have used, so I saw the performance is different on the same monitor) n card DIY performance is not as good as a card, your CPU is AMD, you need to install 4n1 motherboard hard disk drive, can be very good with a card

no matter a card or n card is different in each period, such as 9500, 9550, 9600, 9800, 5200, 5600, 5700, 6200a, 6200. In this period, a card is obviously better than n card. In the later period, n card has always been less dominant. For example, 7300gt, 7600gt, 7900gt are the mainstream, and a card is not as good as n card in this period, So when you ask questions about graphics cards, you should be more careful about what you are used for, what your requirements are, what your future development hopes are, and what's more, the price difference between a card and N card in the same level is not very big
I have always been in the choice of n-card, because I have always used games as my evaluation of graphics cards, and my friend is a graphic designer. He has always used a-card and never used n-card, so a-card and n-card are worth mentioning. Another thing to pay attention to is that many a-cards have run points, That is to say, the running time of 3D Mack is very high, but it can't be compared with the running time! When you choose a graphics card, it's a right and wise choice to read more information, evaluate and ask more talents
even if someone tells you who is absolutely better than who, then there is a subject and object element in it. Two trumps have been in IT instry for so many years, there must be its advantages and disadvantages, no card is absolutely dominant, nothing is perfect ~

after the introction, evaluate by yourself
6. N card, manufacturing process is a card can't compare. Let me take a popular example: n card is Nike; A card is MetS Bonwe. Although you can't feel any special difference on your body, fan is there
7. A card's picture rendering is better (intuitive feeling picture is better than n card, n card and a card's picture is darker than a card)
n card's game playing speed is faster than a card (many games are optimized for n card),
n card's driver is more mature than a card
generally, one SP of N card is equal to four of a card
although a card's specification is often higher than n card, However, e to the failure of the driver, the performance of card a cannot be fully utilized
because the SP frequency of card n is twice the core frequency, The SP frequency of ATI graphics card is equal to the core frequency
generally speaking, n card is more high-end than a card
in these two kinds of graphics cards:
NVIDIA graphics card is higher than ATI's same grade graphics card for games
but ATI graphics card is slightly higher than NVIDIA's same grade graphics card in terms of video and audio
if you use games, it is recommended to use NVIDIA graphics card
in terms of performance, the level from low to high is like this
n card: le-gs-ge-gt-gts-gtx
a card: gt-pro-xt-xtx
8. AMD's card is characterized by reality, gorgeous color and better picture. NV's card is characterized by fast game running by default. Under the standard picture quality, a card of the same level is not as fast as n card in most games. But if you improve the resolution, or even turn on 8 times anti aliasing, then the advantage of a card at this time is obvious< A card with similar performance is generally 100 pieces lower than n card. For the same price card, a card is generally 100 pieces lower than n card. For the same price card, a card is generally 100 pieces lower than n card. For the same price card, a card is generally 100 pieces better than n card, Then recommend a card
9. In terms of top-level game cards, NVIDIA has certain advantages, such as lower power consumption and stronger performance. However, AMD and NVIDIA can't keep up with each other in the mainstream of high-end desserts, mid-end and low-end. Which one is better depends on the specific model of the graphics card. We can't just look at the camp. For example, the low-end n card is not as strong as the mid-end a card, and the low-end a card can't win the mid-end n card
as for the difference, it is mainly architecture difference. At present, the latest architecture of AMD is Vega, the mainstream graphics card is gcn4.0, and the N card is Pascal. The specific architecture analysis network searches a lot (for example, search Pascal architecture and Vega architecture as keywords), and it will not be copied
corresponding to consumers, the main differences are as follows:
1: same energy N card has lower heat and power consumption; 2: A card with the same price has better performance; 3: A card color looks more comfortable, and the details of the game rendering more in place; 4: N card color tends to be true, but there are some differences in details
focus on the performance and cost performance of the game, and choose your favorite graphics card to buy. The mainstream graphics cards in the market are game cards. There is no saying that n card is more suitable for the game. Professional graphics cards have corresponding professional series.
