Maximize Unreal Engine Performance: Choosing Between 32 or 64 GB RAM

Estimated read time 3 min read

If you’re a developer working with Unreal Engine, you know that performance is key to delivering high-quality experiences to your users. One of the most critical components of any system is memory, and when it comes to choosing between 32 or 64 GB RAM for your Unreal Engine setup, it can be tough to make a decision. In this article, we’ll explore the pros and cons of each option and provide some guidance on how to choose the right one for your project.

Why Memory Matters in Unreal Engine

Before we dive into the details of 32 vs 64 GB RAM, let’s first understand why memory is so important in Unreal Engine. At its core, Unreal Engine is a real-time rendering engine that requires a lot of processing power and memory to handle the complex graphics and animations that you create. Without enough memory, your system will slow down, lag, or even crash, which can be incredibly frustrating for both you and your users.

On the other hand, having too much memory can also be problematic, as it may not be used efficiently, resulting in wasted resources and a less-than-optimal performance. That’s why it’s important to strike the right balance between memory capacity and usage efficiency.

32 GB RAM vs 64 GB RAM: What’s the Difference?

Now that we understand why memory is so important in Unreal Engine, let’s explore the differences between 32 and 64 GB RAM. At a high level, the main difference between these two options is the amount of memory they can hold. 32 GB RAM can hold up to 32 GB of data, while 64 GB RAM can hold up to 64 GB of data.

However, there are other factors to consider as well. For example, some systems may be configured to use only one channel of memory (i.e., only half the available capacity), which can limit performance. Additionally, some Unreal Engine features and plugins may require more memory than others, so it’s important to choose a setup that can accommodate your specific needs.

Which Option is Right for You?

Ultimately, the decision between 32 or 64 GB RAM will depend on several factors, including the size and complexity of your project, the hardware you have available, and your budget. In general, if you’re working on a smaller-scale project with fewer complex graphics and animations, 32 GB RAM may be sufficient. However, if you’re working on a larger-scale project that requires more processing power and memory, 64 GB RAM may be a better choice.

It’s also worth considering the cost of each option. While 64 GB RAM is generally more expensive upfront, it may be more cost-effective in the long run if you need to upgrade your system down the line. Additionally, some systems may have expandable memory options, allowing you to add more RAM as needed without having to purchase a new system entirely.


  • Q: What’s the difference between DDR4 and DDR5 RAM?
    A: DDR5 is the latest generation of RAM and offers faster speeds and higher memory capacity than DDR4. However, it’s also more expensive.
  • Q: How do I know if my system supports 64 GB RAM?
    A: Check your system specifications to see if it has a slot for 64 GB RAM. You may also need to purchase a new motherboard and/or power supply unit to support 64 GB RAM.
