The difference between AT and ATX motherboards, the difference between ATX motherboards and matx

ATX motherboards are improved AT motherboards, which have optimized the layout of the components on the motherboard to be used with a dedicated ATX chassis and power supply Now you can't see AT motherboards on the market anymore, and the next generation of motherboards with new technology, BTX motherboards, is also coming soon.

The difference between AT and ATX, this topic is a long time ago, or in the 586 era, which is the era when the legendary Pentium became popular.

ATX and AT are just a standard, which is a standard that stipulates the distribution of components on the PCB, and later there is the BTX standard, which emphasizes the overall heat dissipation.

The AT standard is very old, and it doesn't make much sense to know it, so if you go to a motherboard diagram of the AT architecture, you can roughly understand the difference between it and the ATX on the market today.

ATX motherboards and M-ATX motherboards differ mainly in terms of standard publication time, size, and number of slots.

1. The difference between the standard publication time.

The specification standard for ATX motherboards was formulated by Intel in 1995, which is the ATX (Advanced Technology Extended) motherboard standard. ATX replaces the AT motherboard specification as the default motherboard specification for newer computer systems.

The M-ATX motherboard standard was published in December 1997.

2. The difference in size.

A standard ATX motherboard is 305 mm long and 244 mm wide.

The standard M-ATX motherboard is 244 mm long and 244 mm wide, equal in length and width.

3. The difference in the number of slots.

ATX motherboards have a total of seven slots, and the location of CPU, I-O slots, and memory slots is more reasonable than that of the previous generation BAT motherboards.

The length of the M-ATX motherboard has been reduced from seven to four, but the width of the slots and the size of the backplate are the same as those of the ATX.

There is no major reduction in performance for the same model of MATX motherboard. The biggest advantage is that it can be installed in a small chassis, which is relatively small and beautiful.

The biggest disadvantage is poor heat dissipation, because the space is small, the heat dissipation is naturally poor. There is also the fact that it is not convenient to expand and upgrade, because the slots on the motherboard are limited.

The differences between ATX and MATX motherboards are: different sizes, different maximum expansion slots, and different chipsets.

1. The specifications are different.

1. ATX motherboard: The size of ATX motherboard is much larger than that of MATX motherboard.

2. MATX motherboard: MATX motherboard, also known as micro ATX motherboard, is much smaller than standard ATX motherboard.

Second, the maximum expansion slot is different.

1. ATX motherboard: The maximum expansion slot of ATX motherboard is 7.

2. MATX motherboard: The maximum expansion slot of MATX motherboard is 4.

Third, the chipset is different.

1. ATX motherboard: The chipset of ATX motherboard is high-end, and there are few cases of interference.

2. MATX motherboard: The chipset of MATX motherboard is low-end, and there are many cases of interference.

Analysis: The specifications of the motherboard installed in the chassis determine the style of the chassis, the notches on the back of the chassis, the keyboard and mouse interfaces, and the power supply used (e.g., AT power supply or ATX power supply).

-There are 2 main styles of chassis: baby at and at used to be popular, ** compared to the design of IBM AT, but it is a little smaller than it. This type of chassis can only use AT-spec motherboards and AT power supplies.

ATX cases use ATX motherboards. When buying a case, you must first determine what kind of motherboard (AT or ATX) you want to install, and then decide to choose a baby AT or ATX case based on the motherboard to ensure that the specifications of the motherboard and the chassis are consistent.

-The ATX case is designed by Intel, which is the most popular now, and the back of the case is designed with several rows of holes and slots that match the ATX motherboard, which are used to connect monitors, keyboards, mice and other devices; The ATX power supply is also used in the chassis, which is different from the AT power supply in that it can be controlled by software, with which you can easily turn the ATX power on or off; Of course, there are many other features of the ATX case, which makes it a bit more expensive than the AT case.
