How to distinguish between AT and ATX motherboards

According to your narrative, the short answer is as follows: You can tell from the shape of the motherboard, namely; Motherboard AT is a kind of motherboard size and structure specification, the motherboard size is generally 13in*12in, the board is integrated with a control chip and expansion slot, AT motherboard has now been eliminated. Motherboard ATX motherboard is Intel's designated motherboard standard.

ATX is an abbreviation for "at extend". ATX motherboards have a size of 12in*, and the main aspect of the improvement over AT motherboards is the relative position of the components on the motherboard, ATX motherboards rotate the components on the AT motherboard by 90 degrees, and the motherboard layout is more reasonable. In fact, motherboards can be divided into 3 categories: AT motherboards, ATX motherboards, and NLX motherboards according to their structure.

What's so good about this, it's all outdated, especially to distinguish size and appearance, how can you determine the size of the motherboard? Nowadays, there are many kinds of motherboards, and each brand and model of various socket interfaces may be different. The only difference really is in the power supply, which is the epoch-making difference, the AT power supply and the ATX power supply.

AT motherboard uses AT power supply, and if you want to turn it off, you must manually turn off the power; ATX motherboard uses ATX power supply, plug in the power to have a standby voltage, shutdown does not need to be manual, shutdown also has voltage to supply to the motherboard. Now we are using ATX power supplies.

The AT standard is designed to size 13"×12"The ATX standard is designed to be 12 inches (305mm) wide and 244mm high. In terms of appearance, ATX motherboards are equivalent to Baby Mini AT-type motherboards with 90 degrees rotation.

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.

Difference Between ATX Motherboard and M-ATX Motherboard:

1. Size. ATX is the largest format with a size of 305 244 mm. It is followed by the Micro ATX, which is slightly shorter at 244 244 mm.

When it comes to the size itself, if your computer case is smaller than the size required for a certain format, you should only be concerned. On the contrary, there is no need to worry that this situation is "too big" for the motherboard, since each case has a standardized layout designed to accommodate any motherboard that can fit inside.

2. RAM capacity.

One of the biggest differences is the number of RAM slots included in the motherboard design. While ATX and Micro ATX motherboards can support up to four RAM modules. That is, if the 2 16 GB kit is installed, the ATX and Micro ATX can support twice as much memory.

However, this isn't a big disruptive factor for gamers, as even 16 GB of RAM is more than enough for today's gaming PCs. However, professionals who work with more RAM-rich software may prefer to use a motherboard that not only supports a higher total capacity, but also allows the installation of a four-module kit.

3. PCIe slot.

The bigger difference between all two motherboards is the number of PCIe slots included in their respective designs. ATX motherboards are leading the way in this segment, as they can have up to 7 PCIe slots. Another one is limited, Micro ATX motherboards up to 4.

Obviously, nano-holes, PCIe slots are used by graphics cards, but can also be used by a variety of other expansion cards: sound cards, in-hole infiltration modems, etc. That said, this should be taken into account when making a choice.

Problems that can arise with Micro ATX motherboards especially stem from where the PCIe slot is located at the edge of the board. So, if the motherboard itself is perfect for a situation, no serious graphics card can make the Natoridge work without extra space.
