Bitcoin n card and a card

1. In terms of warranty, n card is generally guaranteed for 3 years, while a card is usually only guaranteed for 1 year
in terms of eth, a card generally needs to brush the BIOS to achieve the highest computing power, and it needs to install a special mining driver
the N card is easy to operate, and the driver can be installed at will. However, the price performance of a card will be higher than that of N card after digging eth
however, in terms of mining life, if eth can't dig in the future, a card may cost a lot. For the time being, a card can only dig Eth and Zec. Zec has proced professional mining machines. In the future, it may not be cost-effective to dig video cards. There are really few currencies that a card can dig. N card is different. Although eth is slightly lower than a card, n card supports many algorithms. There are more than 100 counterfeit coins that can be g. One day, Eth and Zec collapse, and you can continue to live by changing any currency. Aiminer supports both a-card and n-card mining.

2. Dig with n card, you can't even collect the electricity fee... If you want to mine, you'd better use a card honestly

3. Hello, the mining of bitcoin is actually doing distributed computing, and the strongest point of graphics card is floating-point computing. A card and N card are more suitable for floating-point operation than a card. N card should spend more energy on rendering, and a card has more Alu units than n card. At this point, a card is 2-3 times faster, so mining speed with a card is faster

4. It's Sha. This is the security mechanism of bitcoin. All transaction records should be packed and divided into blocks, and Sha hash should be calculated. Only blocks with a specific hash value can be recognized by the network. Each block contains the hash value of the previous block to form a block chain. If there are more than one branch chain at a time, only the longest chain is recognized. The counterfeiting of small computing power cannot catch up with the long chain. You can't fake Transactions unless you have 51% of the computing power. Therefore, the more scattered the computing power is, the higher the total computing power of the whole network is, and the more secure the network is.

5. The two can't be compared, it depends on which aspect you are in, for example,
after the general game is launched, n-card users can play it one month earlier than a-card users
the default image quality of a card is the highest, and that of N card is the lowest
there are also a-card users who like to watch DVD and n-card users who like to play 3dsmax
a card is better at running D3D, n card is better at running OGL
there are also instructions when the driver is updated:
n card: the driver improves the quality of AF, and enables you to have * *% performance improvement in... Games. It is recommended to download
a card: the driver improves the quality of DVD playback and corrects the bug in the game. It is highly recommended to install
in addition, shrinking n-cards usually have no official name, while shrinking a-cards usually have official names
in addition, the n-card driver likes to conflict with small games, and the a-card driver likes to conflict with big games
in addition, the n-card driver likes to play digital games, as if the driver developers change a few lines of code every day, and then hand it over to the hardware manufacturer for release, which will be officially released three months later. The monthly number of a card increases by 0.1 on time, even if the development is not completed

6. A card, nicknamed mine card, is specially used for mining

7.

The differences between the two are as follows:

1. Different manufacturers

1. N card: refers to the graphics card procts developed by NVIDIA company

2. A card: refers to the graphics card procts developed by AMD company

Second, the architecture is different

1. N card: the control unit accounts for a large proportion of the consumption of transistors. In the case of the same number of transistors, n card can do a lot less computing units

2. A card: it adopts a general 1D stream processor as the execution unit, but it adopts an instruction level parallel architecture, with every five stream processors as a group

Three, different advantages

1, n card: n card architecture is highly efficient, flexible, and easy to play its e performance in practical application. But the power consumption is difficult to control

2. Card a: the stream processor of card a is generally 4-5 times of that of card n, the theoretical computing power is also far stronger than that of card n, and the power consumption is relatively lower

The structure of general graphics card is as follows:

capacitance: capacitance is a very important component of graphics card, because the quality of display image mainly depends on the quality of capacitance, which directly affects the quality of graphics circuit

Display memory: it is responsible for storing all kinds of data that the display chip needs to process, and its capacity and performance directly affect the display effect of the computer. The new video cards all use DDR3 / ddr5 video memory, and the mainstream video memory capacity is generally 1GB ~ 2GB

GPU and fan: GPU is the chip of graphics card, which is responsible for most of the computing work of graphics card, rather dry the role of CPU in the computer. The function of GPU fan is to heat the GPU

graphics card interface: it is usually called golden finger, and can be divided into PCI, AGP and PCI Express. PCI and AGP display long interface are basically eliminated, and PCI Express is the mainstream graphics card in the market

peripheral interface: the long peripheral interface is responsible for the output task of the graphics card. The new graphics card includes a traditional VGA analog interface and one or more digital interfaces (DVI, HDMI and DP)

bridge interface: the medium and high-end graphics card can support multiple blocks working at the same time, and the bridge interface is connected between them through the bridge

8. A card is characterized by reality, gorgeous color and better picture. It is more colorful than n card at the same price
n card is characterized by attention to detail, and it has more advantages under the standard image quality
a card of the same level is not as fast as n card in most games. N card is optimized, and its anti aliasing and large resolution are better than a card. In terms of cost performance, a card of the same level is higher.
a card of the same price, n card, a card is better
with the same ability, a card and N card are about 200 yuan more expensive than a card.
