Best Computer For Catia

CATIA is a software suite used for a variety of tasks, such as Computer Aided Design and Manufacturing, PLM, and 3D. It goes beyond traditional CAD software, and offers a Digital Product Experience. This software benefits from a strong GPU, but other components in the build are important in a workstation for CATIA.

In this article, we’ll be talking about the components you need to build the best workstation PC for CATIA.

Why choose us?

Parts like CPU cooler, Power Supply Unit, and chassis are often glossed over when putting together a system like this. Surprisingly, these parts have a massive effect on the lifespan and performance optimisation of the CPU, GPU and RAM. We only use parts that guarantee excellent cooling, airflow, and power delivery.

We’ve also got a lot of experience in putting these systems together, and our cable management is flawless. This not only means dust will be a lot less of an issue, but it will be much easier to work with when you eventually need an upgrade. This will only happen several years down the line, of course. Not to mention our cases just look fantastic.

Each Modena Computers Workstation is tailored to the personal needs of the user, but the features below would make for a great starting point for a workstation for CATIA.

CPU – Frequency

The CPU is not the main priority in a workstation for CATIA. That being said, speed might be important for you depending on the other programs you might be using.

Most modern CPUs run at respectable frequencies, and AMD CPUs in particular have great IPC (Instructions per Clock).

CPU – Core Count

With the relatively minimal CPU requirements of CATIA, an AMD Ryzen 5 5600X would be a great starting point. Keep in mind though, if you won’t just be using this workstation for CATIA, you might want more cores. One example would be if you plan on doing any rendering work.

It’s important to consider all of the programs that form your personal workflow, as these will dictate your overall system requirements. We’d love to give you a consultation and help you work all of this out. We have a  lot of experience with a wide range of software, and a good understanding of which processes are handled by which components.



It is common for PC builders and manufacturers to recommend Nvidia Quadro cards for these kinds of applications, and CATIA does appear to be one of the programs that does benefit from the features of these kinds of cards. 

One feature in particular is double-precision floating-point support. It should be noted that Nvidia is currently phasing out the Quadro brand name, but will still be producing cards with the same features and goals. 

The RTX4000 is a great place to start, as CATIA needs all the graphics power you can give it. While you shouldn’t skimp on the rest of your PC, especially if CATIA is not the only program you use, the graphics card should be your main priority when it comes to the allocation of your budget.


RAM is another important factor in a workstation for CATIA. The general rule of thumb for CATIA is 3-6GB per CPU core.

It really does depend on the size of your projects, though. We have found that 32GB is a great starting point for this program, but if you plan on working on larger projects, 64GB would be a better decision for you.



Storage technology has come a long way over the past decade. Solid State Drives are known to be much faster than mechanical hard drives, but they’re also seen as pretty expensive.

It was pretty common to install the OS on a 120GB SSD, and everything else on a 1TB HDD, so that you could at least start up your PC super quickly.   

Recently it’s become more viable to just use a larger SSD, from around 500GB to 1TB, and this is exactly our approach with our PCs. Having everything stored on SSDs means you’ll be able to save and load programs, and also transfer data, at incredible speeds. The SSDs we use are M.2 form factor and use the NVMe protocol, which means they take up no additional space in your case, and are even faster than standard 2.5” SATA drives.

These drives save a lot of time, and that means the PC will pay itself off a lot faster. You also still have the option of adding in some HDDs if you need to.


As we said before, each Modena Computers Vulcan Workstation is custom built to the workflow and budget requirements of its user. It’s important to consider other programs you may want to use with this workstation.

During our consultation process, you can let us know exactly which programs you want to use with your machine, and we’ll be happy to help you understand what you need. 

Keep in mind that opting for higher performance right out of the gate offers much greater value than getting exactly what you need right now. A higher performance PC won’t need downtime to upgrade any time soon, and will also allow you to complete more work in less time. It could pay itself off a lot sooner than a more affordable option.
