A card and N card of Ethereum
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 advantages1, 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 GPUgraphics 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
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.
1. A card is suitable for playing games, and N card is suitable for design
2. Generally speaking, n-card is more high-end than a-card. It's also fun to buy the right n-card, and it can do pictures, film and television design. If you only play games, buy a 256 video memory will not be eliminated for a while
3. The technical emphasis of N card and a card is that n card pays attention to 3D performance and speed, and a card pays attention to 2D image quality
4. The advantage of N card is that the frequency of the graphics card can reach nearly 100%. The disadvantage is that the power consumption is high. The advantage of a card is that the power consumption is low. The disadvantage is that the software optimization is not enough
5. The n-card architecture is highly efficient, flexible and easy to perform in practical applications, but its power consumption is difficult to control and its theoretical computing power is limited by fewer processing units
6. The advantage of a card architecture lies in its theoretical computing ability, but its execution efficiency is not high, and its adaptability to complex and changeable tasks is not strong, so it needs software support to play its e performance.
but if it refers to cryptocurrency, it should be cautious. Dragon coin is not legal in China because its model is not up to standard. It is suggested to pay attention to bitcoin, Ruitai coin, Laite coin and other mainstream digital currencies.
