Why are there so many models of motherboards

When choosing a motherboard, you should consider many factors. Here are some tips for buying and hoping it will be helpful to you. 1. Several major elements of motherboard purchase - PCB board.

PCB board First of all, look at the thickness of the motherboard, the thick one is appropriate. Then observe whether the number of layers of the motherboard circuit board and the wiring system are reasonable. Pick up the motherboard, look at the light source through the motherboard, if you can see the wiring components on the other side, it means that the motherboard is a double-layer board; Otherwise, it is a four-layer board or a multi-layer board, and the latter should be chosen when purchasing.

Carefully observe the production date, model number, and brand logo of each chip of the motherboard. The production date of each chip should not exceed three months, and the logo on the chip should be clear and legible, without obvious marks such as scratches. Most of the market is not specially marked are four-layer PCB, the experience is now less than 1,000 yuan unless the goods are thrown and dived basically....

As a manufacturer, it is necessary to consider the three levels of the market, too few product models, there is no competitive advantage, so the more comprehensive the product chain, the more vitality the brand, that from 300 to 3000, every customer can buy the right motherboard, isn't it what the business wants?

P and G series are generally equipped with Intel's U.。。 There is also a kind of board called a start. It's generally AMD's U.。。 Read the instructions. Usually there will be a series of U that says.

Motherboard size classification.

Large boards: ATX, mini ATX, XL-ATX, non-standard e-ATX

Small boards: matx, ATX, flexatx

Mini boards: ITX (including Thin-ITX).

Oversized boards: standard E-ATX, EE-ATX, HPTX, WTX

1. The size and area are different.

The ATX version is sized and shaped as a rectangular board.

MATX small board board board with the size and square shape.

The size of the UATX version motherboard is that the board is also rectangular, which is smaller than the MATX area.

The picture below shows the ATX motherboard, you can see that there are 4 memory card slots and 2 graphics card slots, and the board is large.

2. The scalability is different.

ATX motherboard hardware has plenty of space, PCI and PCI-E have more expansion slots, you can insert single or multiple independent sound cards, graphics cards and ** capture cards, etc., memory slots are generally 4 (higher end products may have 8), power supply mode uses at least eight phases of power supply, so this motherboard performance and expandability are the best compared to the other two versions.

MATX generally has two PCI-E slots, and the CPU power supply group is seriously shrinking, but the first-line mainstream big brands will not be less than 4 phase power supply. Compared with ATX motherboards, the scalability is extremely poor, and there will be a lot fewer interfaces of various types of scale, generally only 2 memory slots, one graphics card slot, and the power supply and heat dissipation of the motherboard are not as good as ATX motherboards.

The UATX board refers to the Ultra ATX board, which is simply understood as the UATX board type is a universal motherboard for small chassis, which can reduce the size of the chassis a lot. The location of the graphics card slot of UATX may be different, and there is no guarantee that it will be plugged in, so the CPU comes with the graphics card.

The picture below shows the UATX board, you can see that on the square board, the number of slots is significantly less than that of ATX, there are only 2 memory slots and 1 graphics card slot.

3. Different uses.

ATX motherboards are suitable for mid-to-high-end high-performance models, generally used in professional fields such as video processing, e-sports, etc.

UATX has the advantages of being easy to place and beautiful to look at. However, the performance is poor, and it is suitable for general minicomputers with low performance requirements, such as most of the word processing work, other simple offices, home audio-visual entertainment, etc.

Because of the poor scalability and limited performance of the MATX form factor motherboard, this type of motherboard is generally used by HDPCs and small barebones.

The picture below shows the motherboard in the MATX form.
