To many shoppers, it may seem strange to have a motherboard that can handle dual CPUs. However, these motherboards have been available for a while, primarily for those who use servers and workstations.
However, with the introduction of affordable and consumer high-core CPUs such as the Intel i9-12900K and AMD Ryzen 5950X, dual CPU motherboards have started showing up on the second-hand market for a cheaper price.
We will clarify all about using a dual CPU motherboard for gaming or work. This will help you decide if purchasing one is a good idea.
Let’s delve right into it!

What Is A Dual CPU Motherboard?
The name of this type of product is pretty self-explanatory: a motherboard that has two sockets, i.e., supports two processors.
Of course, there are some limitations to what you can fit in it. The processors need to be the exact same model, otherwise, users may face a variety of issues.
Technically, it doesn’t have to be the same CPU, but it needs the same number of physical and logical cores, the same TDP, and the same RAM speed.
It’s best just not to mix and match processors.
What Are Dual CPU Motherboards Used For?
By placing two processors in one system, you are essentially merging the strength of the two. You would obtain additional computing capability, additional cores/threads, extra RAM slots, further PCIe lanes, etc.
If you need a lot of space to store things, a motherboard with two CPUs is great. You can put in more than 10 hard drives or solid-state drives (SSDs). That means you could have hundreds of terabytes of storage.
Software utilizing parallel processing (two CPUs) can also see benefits. Things like research, science, medicine, drug development, image/video processing, and more all rely on parallel computing.
Anyone in graphic design or video editing can utilize those several dozen cores to render images or videos in just a few minutes compared to several hours.
Can Dual CPU Motherboards Be Used For Gaming?
If combining two processors in one motherboard delivers so many advantages, can this power be used for gaming?
Yes! You can definitely use these things to game. But, you won’t get what you’re expecting out of it.
Should You?
The short answer is no. You shouldn’t aim to buy a dual CPU motherboard if you plan on using the system for gaming only.
Here’s a video from Linus Tech Tips running a game on a dual-socket 16-core system.
The main cause for this is that video games are not designed to make use of all the additional cores and threads or for parallel processing. Those additional PCIe slots, SATA connections, and RAM slots will have no value to you.
You won’t be getting any kind of extra performance from that second CPU. In fact, you might even face FPS loss or other issues such as stuttering, jittering, etc. To get a normal gaming experience, you would have to disable the second CPU to resolve your issues.
And even after that, the performance will be subpar.
Dual CPU Motherboards For Productivity Tasks
If, on the other hand, you are looking at these motherboards to boost your productivity for work, this might not be such a bad idea. More cores can help you speed up your video editing process.
However, you still have cheaper, faster, and more power-efficient options from AMD and Intel. Intel’s 12900K or AMD’s Ryzen 5950X and 3950X are great options. Although these don’t go above 32 threads.
If you need more than that, you could go for Threadripper processors, which do get a bit expensive (up to $4000). In that case, you could try searching the second-hand market to get a dual CPU motherboard with two processors and RAM.
You could probably grab such a system for less than $1000.
Disadvantages
Even if you do manage to find a really cheap two-CPU system, there are some disadvantages you’ll have to consider.
- No real advantage in processes that can’t utilize parallel processing
- Much higher power draw than a consumer PC
- If it’s cheap, it’s an old and outdated platform
- Worse performance in games
These disadvantages are not something to scoff at. It can impair your overall PC experience.
Conclusion
Motherboards with two CPUs were useful in the past, and they offered a less expensive choice than buying a processor with numerous cores that was priced at $10,000.
However, the purpose of these motherboards has dropped significantly because CPUs like the Threadripper line have up to 128 threads and are considerably faster, easier to set up, and draw less power.
In general, motherboards with two CPUs aren’t worthwhile and should only be thought about if they’re very inexpensive.
Please note that these kinds of motherboards are still being manufactured for updated server processors such as the Epyc series. However, these processors, motherboards, and DDR4 LRDIMMs are significantly more expensive compared to previous Xeon (now affordable) systems.
