What Computer Do You Need to Run SOLIDWORKS?
SOLIDWORKS publishes a hardware requirements page. It lists minimum specifications and a certified hardware guide. If you have found it, you have probably also noticed that it does not give you much help making an actual buying decision.
What does certified GPU mean in practice? Should you buy a laptop or a workstation? How much RAM is actually enough? When does a faster processor matter more than more cores?
These are the questions engineering managers ask us when they are spec-ing out machines for a new hire or upgrading an aging workstation. Here is what we tell them, informed by years of support calls, hardware troubleshooting, and real-world performance comparisons.
Can I skip GPU Certification?
The single most important hardware decision for a SOLIDWORKS workstation is the graphics card. Specifically, whether it is on the SOLIDWORKS-certified GPU list.
Certified GPUs are graphics cards that the manufacturer has worked with SOLIDWORKS to test and validate. The drivers are tuned to handle how SOLIDWORKS Design calls the GPU, and when something goes wrong, there is an actual support relationship between the card manufacturer and Dassault to resolve it.
Non-certified cards, including consumer gaming cards from well-known brands, do not have that relationship. They may work most of the time, but they introduce a specific category of problems that are difficult to diagnose and impossible to get manufacturer support for.
What do GPU problems actually look like?
Here are real examples of issues that come from running SOLIDWORKS on a non-certified GPU.
• You right-click on a part in an assembly drawing to open it. SOLIDWORKS crashes. The crash is triggered by how the GPU handles the call to open a new window, and a gaming card may not handle that call correctly.
• A new window opens but the screen is blank. Moving the cursor around the screen gradually reveals the content, as if you are wiping a fogged window. The display is there but the GPU is not rendering it correctly until forced to.
• Features like RealView Graphics and Ambient Occlusion are disabled or unavailable. These are rendering capabilities that require a certified card to function and may simply not work on consumer hardware.
None of these issues necessarily prevent you from using SOLIDWORKS Design. But they create instability, slow down workflows, and when they come up in a support context, the answer is always the same: SOLIDWORKS has not tested against your card and cannot commit to a fix.
If budget is tight and you are choosing between a faster certified GPU and a more powerful non-certified one, choose the certified GPU every time.
How should I pick a CPU for SOLIDWORKS?
SOLIDWORKS design operations are largely single-threaded. Rebuilding models, processing changes to assemblies, generating drawings, these tasks run primarily through one core. That means clock speed matters more than core count for most your engineers' day-to-day work.
A processor with 16 cores that can boost to 5.6 GHz on its performance cores will outperform a 24-core processor with a lower maximum clock speed for most SOLIDWORKS Design tasks. When shopping for a processor, prioritize the maximum boost clock speed on the performance cores.
There is one important exception: SOLIDWORKS Simulation and Flow Simulation are multi-threaded. They can use multiple cores to distribute the computational load of a solve. If a workstation is going to be used regularly for Simulation, especially CFD, having more cores translates to faster solve times. For a dedicated simulation workstation, a higher core count becomes more relevant.
For a general design workstation, go for the fastest single-core performance you can get in your budget. For a simulation workstation, balance core count with clock speed based on the complexity and frequency of your jobs.
What is the minimum RAM for SOLIDWORKS?
SOLIDWORKS lists 16 GB as its minimum RAM requirement. That is the floor, not the recommendation.
In practice, 32 GB is a more reasonable starting point for a working engineer. At 16 GB, you will notice performance degradation when working with large assemblies, particularly if you want to load the full assembly rather than running in lightweight mode. Lightweight mode reduces load times by partially loading components, but it limits your ability to edit and interact with the model.
64 GB is what we at SWYFT Solutions consider the sweet spot for a professional SOLIDWORKS workstation. It gives you enough headroom to work with large assemblies fully loaded, run moderate simulations, and handle large STL files without constantly bumping into memory limits. For most engineers, you will not use more than that.
128 GB is available and may be worth it for dedicated simulation workstations running very large models or complex CFD analyses. For a general engineering workstation, it is unlikely to translate into noticeable improvement and adds significant cost.
RAM summary by use case
• General design, small to medium assemblies: 32 GB minimum
• Large assemblies, complex models, frequent design work: 64 GB
• Dedicated simulation or CFD workstation: 64 to 128 GB depending on model complexity
Is a laptop or workstation better for SOLIDWORKS?
This question used to have a clear answer. Six or seven years ago, workstations were meaningfully more powerful than laptops and the gap mattered for SOLIDWORKS performance. That gap has largely closed.
Modern certified professional laptops from manufacturers like Dell, HP, and Lenovo can run SOLIDWORKS at full performance for most engineering tasks. The convenience of a laptop, the ability to bring it to a customer site, work remotely without VPN sluggishness, or take it to a manufacturing floor, typically outweighs the marginal performance difference for most engineers.
Our general recommendation today is to default to a laptop unless there is a specific reason to do otherwise.
There are two cases where a workstation makes more sense.
• Dedicated simulation or rendering station: If you have one machine that is specifically going to run long Simulation solves or generate rendered animations in SOLIDWORKS Visualize Pro, a workstation is the right tool. It does not need to travel. It can be optimized for raw compute performance. You can often get more performance per dollar in a workstation form factor because the manufacturer is not engineering around heat and battery constraints.
• Budget-constrained environments: For the same performance level, a workstation is often less expensive than a laptop because the engineering challenges of fitting that hardware into a compact mobile form factor add cost. If mobility is not a requirement, the workstation may give you more for your money.
For everyone else, give your engineer a certified professional laptop with enough RAM and GPU, and let them take it wherever they need to go.
What about SOLIDWORKS xDesign and these requirements?
If hardware budget is a genuine constraint, it is worth knowing that SOLIDWORKS xDesign is a fully browser-based design tool that requires no local hardware beyond an internet connection. You can design parts, assemblies, and drawings from any device. It is not the same as desktop SOLIDWORKS in terms of capability, but for certain workflows and team configurations, it removes the hardware question almost entirely.
What is the recommended hardware specs for SOLIDWORKS?
• GPU: Always use a certified card from the SOLIDWORKS hardware compatibility guide. This is non-negotiable.
• CPU: Prioritize clock speed over core count for general design. Add cores if simulation is a significant part of the workload.
• RAM: 32 GB minimum for working engineers. 64 GB recommended. 128 GB for heavy simulation-only workstations.
• Laptop vs. workstation: Default to a laptop. Use a workstation for dedicated simulation or rendering stations, or where mobility is not needed and you want more performance per dollar.
Hardware decisions look simple on a spec sheet but have real consequences for stability, performance, and supportability over the life of the machine. If you want to talk through what makes sense for your specific team and workload, the SWYFT Solutions team is available for that conversation. We spec machines for engineering teams regularly and can help you avoid the most common mistakes before you spend the budget.
