What do they say about the graphics card, what is the difference between the A card and the N card?

One is a dedicated graphics card and the other is an integrated graphics card.

1. A card is actually the abbreviation of AMD graphics card, and N card is a graphics card produced by NVIDIA. Each stream processor in the GPU in the N card has a complete arithmetic logic unit function, and when an operation instruction is issued, each stream processor can fully work. The GPU in the A card graphics card each stream processor of each 5 stream processing units are fixed, can not be disassembled and reassembled, if in the processing of pure 4G instructions, each stream processor can only process one instruction, and one stream processor unit is idle, but can not join other combinations, work together.

To put it simply, when a task is sent, the GPU of the N card only needs one stream processor to complete the work, and the GPU of the A card needs 5 stream processors to complete, although the number of A card combination work is relatively large, but there are 4 will be idle, because these 4 stream processors do not have independent functions, can not perform function operations, floating point operations.

2. Compared with the computer graphics card A card and N card, the A card will be more excellent in terms of audio and video and graphic design, and the N card will be more excellent in terms of game performance, of course, for ordinary users, the difference between the two graphics cards is not too big.

1. Different manufacturers: A card refers to the graphics card products developed by AMD, while N card refers to the graphics card products developed by NVIDIA.

2. Different architectures: A card uses a general-purpose 1D stream processor as the execution unit, but adopts an instruction-level parallel architecture, with every 5 stream processors as a group. The N card control unit accounts for a considerable proportion of the consumption of transistors, and in the case of the same number of transistors, the N card can do relatively few computing units.

3. Different advantages: the stream processor of A card is generally 4-5 times that of N card, and the computing power of Li Seep guessing theory is much stronger than that of N card, and the power consumption is relatively low; The N-card architecture has extremely high execution efficiency, and the spirit cluster is large and active, which is easy to play its due performance in practical applications. However, power consumption is difficult to control.

4. The audio and video effects are different: the NVIDIA graphics card is higher than the same grade graphics card of ATI for games, but the ATI graphics card is slightly higher than the same grade graphics card of NVIDIA in terms of audio and video.

5. Different technical emphasis: N card and A card focus on technology in that N card focuses on 3D performance and speed, and A card focuses on 2D plane image quality.

The so-called N card and A card are distinguished by the graphics card chipset used:

N-card refers to a graphics card with an NVIDIA chipset.

At present, it is common to see independent N cards on the market to GTX; gts；gt, e.g. GTX590; gts450;GT220 and so on.

A card refers to a graphics card with an AMD (ATI) chipset.

At present, it is common for independent A cards on the market to start with HD, such as HD7970; hd6770;HD5450 and so on.

I'm talking about most of the discrete graphics cards sold on the market now, of course, some integrated graphics cards and older graphics cards are not named according to this rule.

As for whether an N card or a card is better, there are different opinions.

Attached is a fun picture (purely for entertainment, this picture does not represent my opinion).

An N-card is a graphics card equipped with a graphics chip manufactured by NVIDIA.

A card refers to a graphics card equipped with a graphics card chip produced by AMD, which used to be called ATI, but ATI has been acquired by AMD, and was once named AMD-ATI, and now it refers to AMD.

To put it simply, a card is an AMD graphics card, and an N card is an NVIDIA graphics card.
