Difference Between ATX and BTX

Difference Between ATX and BTX

BTX and ATX motherboards are 2 types of the same board, designed with different features in mind. You can compare the motherboard to the brain of your computer, it houses many essential components to keep everything running smoothly.


The contrast between BTX and ATX is that in the earlier version, ATX has been around for much longer. It also makes use of a motherboard setup that maximizes cooling capabilities by placing all components in one area. The newer BTX on the other hand features multiple layers with more space allocated per layer than before.

The launch of the BTX version was a major technological breakthrough that allowed processors to be not only more efficiently heated but cooled as well. This advancement in computer technology has changed the way computers are made and used today!

Table of Comparison Between BTX and ATX

Parameters of Comparison The ATX The BTX
Definition ATX boards were created for replacing the older, and less efficient design of an American-type system called an “AT.” The BTX board was introduced in order to enhance the cooling procedure of the used processor.
Full form Advanced Technology eXtended. Balanced Technology eXtended.
IO Port Situated at the top side of the board. Situated at the bottom side of the board.
Airflow Less than the BTX. More than the ATX.
Usage Extensively used in desktops. Not that popular for desktop use.

What is an ATX?

ATX is a traditional motherboard that came out in 1995 and has been around for over 20 years. It’s so popular because it was created by Intel to replace their old AT design, which had been used since the early 80s!

ATX motherboards have components placed near their power supply units (PSU) which block airflow and cause heating issues as well! The arrangement of the ATX’s memory modules and input-output ports is such that they block airflow. This is why these parts must be on top since airflow through them would cause problems with the cooling system design!

The ATX system has been around for quite some time and people are already used to this type of motherboard. They don’t want to replace their old version because it’s easier than installing another panel on top with all its wires, cables, etc., so they just put up with whatever problems come along in order to avoid having any hassle! The Intel Corporation has made power-saving changes to its processors in an effort to continue with ATX boards.

What is a BTX?

The introduction of the new BTX motherboard has been a huge step forward for Intel, as it enables them to cool their processors better. With this change came an idea from Big Tech companies such as Microsoft and Apple who were looking into ways on how they could reduce heating issues in laptop computers – something that was previously non-existent with traditional ATX motherboards!

BTX is a genius design that maximizes airflow to avoid overheating of processors by maximizing the pathogen. The modifications made on components such as motherboards allow maximum coolant circulation and improve cooling efficiency overall!

In order to keep the components cool, a newly designed funnel for airflow is at work near where you would find your processor. Blowing hot air onto them helps by dissipating it away and bringing fresh cold ones over for cooldown purposes!

The IO slots and ports arrangement has been replaced. The input/outputs of the board are now placed on the upper side, while slots of add-on can be found at the bottom for better airflow in your case! The extra slots are now placed at ground level, ensuring proper flow for cooling purposes even though they’re still aligned with each other like before!

Despite being in high demand, the BTX boards are rare to find because people who already have ATX systems don’t want to change. The ATX format is more cost-effective. Intel decreased the consumption of power of their CPUs, which causes less heat production and makes this type effective for heating systems with high requirements.

Difference Between BTX and ATX

The ATX motherboard was produced to develop the older version, whereas BTX is newer and intended for maximum cooling of processors.

The full forms of ATX and BTX are Advanced Technology eXtended, and Balanced Technology eXtended respectively.

The design of the ATX motherboard blocks the flowing air whereas BTX motherboards allow for more natural circulation.

The IO ports are situated on either side of the ATX board. In contrast, the I/O locations for BTX boards lie at ground level and can be accessed by removing a panel above them.

The ATX board is more popular on desktops, while the BTX one hardly ever appears.

The ATX designed motherboards provide an excellent design for cooling, whereas the BTX requires more complex components to be installed in order to achieve maximum airflow.


BTX designed boards are the perfect choice for those who want to cool their processor with extra care. The design of this motherboard has been specifically tailored so that all components can remain properly ventilated, which will help make sure your system runs smoothly and efficiently at maximum speeds!

To avoid the motherboard from overheating, many components have been shifted and thus maximizing airflow. The ATX design is still popularly used in computers, even though it has been replaced by the BTX standard.
