B450 vs X470 Motherboard- Know The Difference

Motherboards are the circuit boards of computers and the whole computer system’s foundation. It has different names like the baseboard, circuit board, system board, etc. Let’s Take A look on B450 vs X470 Motherboard in Detail

The motherboard of a computer system is responsible for all the actions that the system will do. From the allocation of power supply to the communication between different computer parts, everything takes place according to the instructions of the motherboard. It provides a connection between different Hardware devices of the computer system. Every type of motherboard has a different processor and memory, and hence they will not work on every system. In simple words, every system has its own unique motherboard, depending on the specifications of the system.  Here we’ll showcase a deep comparison between B450 vs X470 Motherboard.

This article will cover a detailed comparison of X470 and B450 models of motherboards. So Let’s Go!

Detailed Comparison of B450 vs X470 Motherboard

B450 motherboard supports first, second, and third-generation desktop processors, Vega graphics and has three expansion slots. It has built-in LED lights with various colors. To make sure that the motherboard remains cool, it has six fan headers over it.

On the other hand, X470 is at the top of the list while talking about the gaming motherboards. It has an expandable storage capacity. In addition to good storage, it encourages the fast speed of processing. It works way faster than the other motherboards. X470 has a dual memory channel, and it has 64GB memory capacity.

USB COMPARISON IN X470 vs B450 Motherboard

In comparison between B450 and X470, X470 motherboard has different USB ports, like two ports for USB 2.0, four ports for USB 3.1 Gen 1, two ports for USB 3.1 Gen 2. On the other hand, the B450 motherboard has three USB ports for USB 3.1 Gen 1, to for USB 3.1 Gen 2, and two for USB 2.0.


While talking about the display, we consider them both at almost the same edge because X470 motherboard supports DVI-D and HDMI display, and B450 supports DVI-D and HDMI 2.0 display.


Both of these motherboards have a distinct audio output. Both motherboards; X470, and B450, supports a sound range of 5×3.5mm.

Memory storage In X470 Vs B450 Motherboard

While talking about the memory, we can give an upper hand to motherboard X470 because it has memory storage for 64GB of data, and B450 has memory storage for 32GB of data.  

Optane memory support

Optane memory is a type of memory in motherboards, which helps in improving the system boot time. If we talk about optane memory in X470 and B450, we will get to know that X470 supports the optane memory feature, while B450 doesn’t help it.
