How does a motherboard differentiate between large and small boards?


For everyone, I will list in detail how motherboard distinguishes between large and small boards. I hope that you can calmly choose when choosing a motherboard for installation.

First of all, let's look at difference between popular B85 small board and small board. We'll take ASUS B85-PLUS big board and ASUS B85M-E small board as examples, let's look at appearance and structure of two.

How does a motherboard differentiate between large and small boards?

ASUS B85-PLUS Motherboard (B85 Large Board)

As shown in picture above, ASUS B85-PLUS large motherboard has a neat layout and many expansion interfaces: 4 memory slots, PCI-E video card slots, 4 PCI slots, 2 USB 3.0 ports and 4 1 USB2.0 interface , 2 STAT3.0 interfaces and 2 SATA2.0 interfaces.

How does a motherboard differentiate between large and small boards?

ASUS B85M-E motherboard (B85 small board)

As shown above, ASUS B85M-E small motherboard has a relatively compact overall layout, but still has 4 memory slots, 4 SATA3.0 interfaces, 2 USB3.0 interfaces, and 4 USB2.0 interfaces, as well as 1 PCI- Slot for video card E and 2 PCI slots.

Based on Huawei B85 large motherboard and small motherboard of same brand above, difference between them is that large motherboard is larger and overall layout is relatively neat, while small motherboard is smaller and layout is larger. compact. In addition, in terms of expansion interface, big board and small board are basically same, difference is mainly that big board has more PCI slots.

Then is it better to have a large computer motherboard or a small one? The author directly concludes this question:

1. First, performance of big and small board is same;

2. The large board expansion interface can be more numerous. For example, a large board comes standard with 4 memory slots, while a small board may have 2 or 4 memory slots. In addition, large board PCI slots are also more common. , other interfaces are basically same;

3. The materials used to make a large motherboard are relatively sufficient and price will be more expensive;

4. For a large board, you need to choose a large chassis over a medium tower, while a small motherboard can be compatible with both large chassis and some mini cases;

Conclusion: The performance of big board and small board of motherboard is same and will not affect performance of computer. Both PCI slots and PCI slots are enough, so when choosing a motherboard, don't worry too much about whether it's a big board or a small one.

For some special cases, such as choosing a small case, we must choose a compatible small motherboard instead of a large motherboard. The motherboard is also very necessary. In addition, high-end computers also have high heat dissipation requirements. The greater distance between equipment installed on motherboard, better, so for these users, it is best to choose a larger motherboard. For middle or low-level users, motherboard requirements are low, so both large and small boards are suitable, but for higher performance, it is generally recommended to choose a small board.
