What is the difference between n card and a card?

Difference: 1. Each stream processor in the GPU of the N card has a complete ALU function, while each stream processor in the GPU of the A card can only process one 4D instruction. 2. N card focuses on 3D performance and speed, while A card focuses on 2D flat image quality. 3. The N card architecture has extremely high execution efficiency and strong flexibility, but its power consumption is difficult to control; the advantage of the A card architecture lies in its theoretical computing power, but its execution efficiency is not high. 4. The effect of N card is slightly softer and the color is slightly lighter; the effect of A card is slightly sharper and the color is slightly thicker. 5. N card is a graphics card product of NVIDIA company, and A card is a graphics card product of AMD company.

Many friends are confused about choosing a graphics card when assembling a computer. Should they choose A card or N card? What is the difference between A card and N card? Here I will popularize this knowledge for everyone.

A card refers to ATI, a graphics card manufacturer, but after ATI was acquired by AMD, we also called A card an AMD graphics card, so the latest graphics card ladder chart indicates AMD graphics cards.

N card refers to NVIDIA, another graphics card manufacturer. nVIDIA's most famous product line is the GeForce graphics card series designed for gaming. So what is the difference between graphics cards A and N? After testing and collection, detailed comparisons were made from many aspects. (For ease of understanding, no professional details will be given)

The difference between n card and a card

1. GPU stream processor Each stream processor in the GPU of different

N cards has a complete ALU function, and each stream processor can fully work when an operation instruction is issued.

The five stream processing units of each stream processor in the GPU of the A card are fixed and cannot be disassembled and reorganized. Each stream processor can only process one 4D instruction.

2. The design focuses of the two are different

N card focuses on 3D performance and speed, while A card focuses on 2D flat image quality.

3. Different architectures

• #N card: The control unit accounts for a large proportion of transistor consumption. With the same number of transistors, In this case, the computing units that the N card can do are relatively few.

• A card: uses a general 1D stream processor as the execution unit, but uses an instruction-level parallel architecture. Every five stream processors are in a group, and each group is once A maximum of one 5D instruction can be received.
  

#N card architecture has extremely high execution efficiency and strong flexibility, but power consumption is difficult to control. The advantage of the A-card architecture lies in its theoretical computing power, but its execution efficiency is not high.

• N card: The N card architecture has extremely high execution efficiency and strong flexibility, and can easily exert its due performance in practical applications. However, power consumption is difficult to control, and fewer processing units also limit its theoretical computing capabilities.
  

• A card: The stream processor of A card is generally 4-5 times that of N card. The theoretical computing power is much stronger than that of N card, and the power consumption is also relatively high. It is lower, and the chip area with the same performance is also smaller.

4. The difference between the two in image processing

The effect of N card is slightly softer and the color is slightly lighter; the effect of A card is slightly sharper and the color is lighter. Slightly thicker.

5. Different manufacturers

N card: refers to the graphics card product developed by NVIDIA.

A card: refers to the graphics card product developed by AMD.
