What is the difference between ATX and microATX

1. The size is different.

The MicroATX (ATX, MATX, or UMTX) motherboard standard was published in December 1997 and is an inch size (244mmx244mm).

The standard ATX console version is 12 inches long and 244 inches wide (305 mm and 244 mm).

2. The number of expansion interfaces is different.

Because ATX is larger, there are more expansion interfaces than MicroATX.

3. The time of submission is different.

The MicroATX (ATX, MATX, or UMTX) motherboard standard was published in December 1997.

ATX (Advanced Technology Extended) motherboard specifications are provided by Intel Corporation.

It was formulated in 1995.

For motherboards, the number of devices that can be plugged in depends on how many expansion slots there are on the motherboard, such as 5 PCI or 6 PCIs, 3 memory slots or 4 memory slots, but this is only a small difference, and the big difference is whether it is an ATX motherboard or a microATX structure. The main difference between the ATX and MicroATX structures is the width of the motherboard, with a standard ATX motherboard width of 305mm compared to 245mm for the MicroATX. The reduction in the width of the motherboard means that the equipment and wiring on the motherboard horizontally must be reduced, and the CPU and power supply parts cannot be reduced, so the main thing that is reduced is the PCI slots, most ATX structure motherboards have 5 to 6 PCI slots, while the MicroATX is often only 2 to 3, and the least even only one.

In addition, there are often only 2 memory slots, and at most only 3, which is a lot less than ATX motherboards. Most users tend to only consider ATX and not MicroATX when buying a motherboard, thinking that it is always good to have more expansion capacity, compared to MicroATX motherboards and standard motherboards**.

One or two hundred yuan, there is really no need to save. However, in fact, few people have really considered what is the use of so many PCI slots and memory slots in the ATX structure, the author went to the market to briefly count the users who really have a demand for PCI slots, the total number of users is 102 people, the statistical time is 7 hours, and the statistical location is in Shanghai Bainaohui Computer Plaza. At present, the most widely used PCI slot is the above, and in fact, the most widely used PCI slot is only 26% of users will use the PCI sound card, in addition, few people think of using other purposes, and fewer will use more than one PCI slot.

The situation of memory slots is similar, the vast majority of users choose 256MB of memory, a small number of users use 2 256MB, and there are only a handful of users who can use 3 memory slots, but in fact, there are not a few users who pursue 4DIMM slots. It can be seen that ATX is more worth buying than MicroATX is just people's inertial thinking relative to the past, and now there is no need for multi-function cards, graphics cards have their own special slots, and sound cards are also integrated into the motherboard on a large scale, and the users of the PCI expansion slot function are no longer too extensive, so why not choose a cheap and high-quality MicroATX motherboard? Although it is difficult for us to guarantee whether there will be PCI expansion cards in the future, it is not advisable to keep too much room for upgrades, not to mention that the ** gap of the yuan is close to 10% of the total price of the motherboard, which is not a small amount.

Excuse me.

ATX chassis refers to the common conventional chassis, which is suitable for ATX standard master and power supply and other hardware, while micro means miniature, which refers to a small chassis with micro master and power supply as the object.

1. The difference is the size of the motherboard and the scalability of the motherboard.

2. The chassis will not be marked, generally judged by the size of the chassis, you can also look at the expansion port, there are generally 5-6 ATX, and less than 4 is microATX.

3. This is equivalent to the first problem, ATX has more interfaces than MicroATX, and it has strong scalability.

The only difference is the size. Microatx is smaller as the name suggests.

The maximum size of the ATX board is 305 244mm, and the maximum size of the microATX motherboard is 244 The motherboard can be installed in an ATX-sized chassis, not the other way around.

In addition, due to size limitations, MicroATX expansion slots and memory slots are generally less than ATX, and most manufacturers integrate display sound chips on MicroATX boards, but this is not a hard and fast requirement. Some MicroATX cases limit the use of low-profile expansion cards.

MATX refers to Micro-ATX, which is different from MINI-ATX as follows

First, the standards are different.

1. Mini-ATX: It is a motherboard, the standard is:'×'，284×208mm。

2. Micro-ATX: The motherboard standard was published in December 1997, and the size is inch.

Second, the characteristics are different.

1. Mini-ATX: There are not many products that use Mini ATX specifications, and most motherboard manufacturers only shorten the length of ATX motherboards, and do not change the width.

2. Micro-ATX: The length is 20% shorter than the Standard ATX, and the standard size of the Standard ATX is 12 inches. Due to the reduced length, the expansion slots have been reduced from a maximum of 7 to 4 ATX slots.

Third, the purpose is different.

1. Mini-ATX: Intel proposed the Mini ATX motherboard specification to save the cost of printed circuit boards.

2. Micro-ATX: Designed to be compatible with ATX. Both have the same width and size of the backplane, and the mounting contacts (screws) are also part of the ATX, so the MATX motherboard can be installed in the ATX chassis.

The ATI RS690 is a Micro-ATX model. ATX indicates the type of board. The prefix indicates the size.

1.Motherboards are not the same size:

ATX Plate Type:

The layout is"Horizontal"The board design is like putting the baby-at form factor upside down, which increases the space for the motherboard to exit the port, so that the motherboard can integrate more expansion gongzhou energy.

ATX is the most common motherboard structure on the market today, and there are many expansion slots, and most motherboards use this structure.

The dimensions of the ATX motherboard are:

With a size of 170 to 170 mm, the strength of the Mini ITX motherboard naturally lies in its small size and low power consumption. It can also be easily integrated into a car or small speaker, and additional hardware is possible.

Micro-ATX form factor: It is a motherboard structure standard proposed by Intel in 97, mainly by reducing the number of PCI, memory slots and ISA slots to achieve the purpose of reducing the size of the motherboard.

There are two common sizes: and.

The main difference between the ATX form factor and the ATX form factor is the size and the number of expansion slots, with the former being suitable for compact models and the latter being popular with enthusiasts.

The Micro-ATX form factor is a motherboard structure standard proposed by Intel in '97, mainly by reducing the number of PCI, memory slots and ISA slots to achieve the purpose of reducing the size of the motherboard. Dramatically reduces the space occupied by the motherboard.

There are two common sizes:

Micro ATX motherboards reduce the number of expansion slots to 3-4 and DIMM slots to 2-3, reducing the width of the motherboard horizontally and reducing its total area by about square inches. More compact than ATX standard motherboards. According to the Micro ATX standard, graphics and audio processing should also be integrated on the board.

At present, many brands of motherboards use the Micro ATX standard, and Micro ATX motherboards are often seen in the DIY market.

ATX is the most common motherboard structure on the market today, and there are many expansion slots, and most motherboards use this structure.

The dimensions of the ATX motherboard are:

ATX is a PC motherboard structure specification published by Intel in 1995.

ATX is a new type of personal computer motherboard specification. It was proposed and developed by Intel and responded to by other vendors. The motherboard we are currently using is a spec called Baby AT.

The layout of the ATX is equivalent to turning the Baby AT motherboard 90 degrees, and changing the straight Baby AT motherboard to a sideways one, which is the biggest specification change for the motherboard. This allows motherboard and PC manufacturers to continue to use their current production equipment, allowing them to design and produce motherboards at a lower cost.

A detailed explanation of ATX power supply technology.

At present, ATX power supply is widely used in computers, and compared with AT power supply, this hail is more compliant"Green Computer"The energy-saving standard dust picker, its corresponding motherboard is an ATX motherboard.

Micro-ATX is also known as Mini ATX structure, which is a simplified version of ATX structure. The main purpose of the Micro ATX specification is to reduce the overall cost of the PC system and reduce the power requirements of the PC system. Key features of the Micro ATX structure:

Smaller motherboard size, smaller power supply, reducing the size of the motherboard and power supply directly reflects the cost of the computer system. While reducing the size of the motherboard can reduce costs, the number of IO expansion slots that can be used on the motherboard is also relatively reduced, and the Micro ATX supports up to four expansion slots, which can be a combination of various specifications such as ISA, PCI, or AGP, depending on the motherboard manufacturer.

BTX English full name: Balanced Technology extended, BTX is very similar to ATX in terms of design concept, but after a series of improvements, the architecture can significantly improve the heat dissipation efficiency of the system and reduce noise, BTX architecture is divided into three styles - standard BTX, microBTX and PicoBTX, respectively, support three different sizes of the system. At IDF Fall 2003, Intel demonstrated a prototype based on MicroBTX and standard BTX architectures.

The MicroBTX architecture only takes up liters of space, while the standard BTX is not much different, and Intel's BTX has been unanimously approved by OEMs.

U-ATX motherboards are generally prepared for the quasi-system, and it is generally ATX simplified version! I won't introduce it here!

Dramatically reduces the space occupied by the motherboard. Micro-ATX: type of motherboard, compact.

There are two common sizes:

1. In terms of appearance: Micro ATX is smaller than the overall size of ATX, and many barebones use this kind of micro ATX motherboard.

2. Function: Micro ATX is more streamlined than ATX motherboards in terms of function and expandability, such as PCI slots, Micro ATX generally provides 1 up to 2;

In addition, the Micro ATX structure motherboard can be installed in the Micro ATX ATX chassis, while the ATX board can only be used in the ATX chassis.

Micro-ATX and ATX are just two specifications of the motherboard size, and have nothing to do with the materials used in the workmanship or performance. They are suitable for different markets. The Micro-ATX is small in size and does not have a lot of space to install complex cooling systems or many expansion slots (memory, boards, etc.), so it generally uses an integrated chipset for users who have high requirements for host size or motherboard cost.

Due to the large size, ATX motherboards have ample space to choose from a variety of chipsets at will, and flexibly match different expansion slot configurations, heatsink settings, onboard chips, and so on. For general mainstream users. So there is no comparison between the two.

However, because Micro-ATX mostly adopts a highly integrated design, and because the user chassis of Micro-ATX motherboards are very small, it is unlikely to install high-end processors and high-end graphics cards with high power consumption and high performance, so relatively speaking, Micro-ATX power supply design and materials are generally not luxurious, but it does not mean that Micro-ATX materials are shrinking and the performance is poor. A well-designed Micro-ATX integrated motherboard from a first-tier manufacturer has the potential to perform much better than a full-size ATX motherboard that looks like an eye-catching second-tier motherboard. The performance of the motherboard is mainly determined by the chipset used and the level of design, and has nothing to do with the size of the motherboard.
