RFEM 6 is a finite element analysis application used by structural engineers to model, analyse and design complex structures. Choosing a suitable laptop requires attention to processor performance, memory capacity, graphics hardware and cooling.
For RFEM, the processor and RAM deserve particular attention. Dlubal recommends allocating approximately 1 to 3 GB of RAM per processor thread, depending on the complexity of the model. It also recommends a dedicated NVIDIA or AMD graphics card, with a midrange gaming GPU being sufficient for many applications.
The following laptops cover demanding structural analysis, large finite element models, detailed 3D visualisation and more affordable engineering setups.

What to Look for When Choosing a Laptop for RFEM
1. Processor Performance
The processor has a significant effect on RFEM calculation performance. Look for a modern Intel Core Ultra 7 or Ultra 9 processor, or an AMD Ryzen 7 or Ryzen 9 processor.
RFEM can use multiple processor threads during calculations. However, Dlubal cautions that distributing calculations across too many cores can increase data traffic and create memory bandwidth limitations.
A processor with strong sustained performance and effective cooling is a sensible choice for intensive structural analysis.
2. RAM Capacity
Memory requirements depend on the size and complexity of the structural model. Dlubal suggests approximately 1 to 3GB of RAM per processor thread.
Recommended memory configurations:
| Type of RFEM work | Suggested RAM |
|---|---|
| Student projects and basic models | 16GB |
| Typical structural engineering projects | 32GB |
| Large finite element models | 64GB |
| Complex models with solid elements and extensive calculations | 96GB or higher |
For professional structural engineering work, 32GB is a sensible starting point, while 64GB provides greater capacity for demanding projects.
3. Graphics Card
RFEM 6 uses graphics hardware for displaying and interacting with structural models. Dlubal recommends dedicated NVIDIA or AMD graphics cards and advises against relying on Intel integrated graphics.
A midrange NVIDIA GeForce RTX or AMD Radeon graphics card is suitable for many RFEM projects. You do not need an RTX 5090 solely to run structural calculations.
4. Storage
Choose a laptop with at least a 1TB SSD. Large structural models, project documentation, software installations and temporary calculation files can occupy considerable storage space.
Dlubal recommends a fast SSD. It also notes that RFEM stores temporary calculation data in the Windows user profile, making sufficient free space on the system drive important.
5. Cooling and Sustained Performance
Structural calculations can place sustained loads on the processor. Thin laptops may reduce processor speeds when temperatures rise.
Gaming and performance laptops generally offer stronger cooling systems, making them suitable choices for engineers who regularly perform demanding calculations.
6. Operating System and Processor Architecture
RFEM 6 is designed for Windows on x86 processors. Choose an Intel or AMD laptop running 64 bit Windows.
Avoid selecting a Snapdragon ARM laptop for native RFEM work. Dlubal explains that its current RFEM 6 version uses x86 software, meaning ARM computers rely on emulation, which can reduce calculation performance.

Which Laptop Should You Choose for RFEM?
Best overall: Razer Blade 18 with Core Ultra 9, 128GB RAM and RTX 5090. Its substantial memory capacity and powerful hardware make it suitable for demanding structural engineering work.
Best workstation alternative: MSI Titan 18 HX with Core Ultra 9, 64GB RAM and RTX 5090. It combines a high performance processor, dedicated graphics and substantial storage.
Best 16 inch performance option: MSI Raider 16 HX with Core Ultra 9 and RTX 5080. It offers a powerful configuration in a smaller display format.
Best value for professional work: Acer Predator Helios Neo 16S AI with Core Ultra 9, 32GB RAM and RTX 5070 Ti. It provides a capable starting point for professional structural analysis.
Best for large models: Razer Blade 18 with 64GB RAM and RTX 5090. This configuration offers substantial processing and graphics capacity, although the 128GB version is preferable when memory demands are very high.
Final Recommendation
For most structural engineers using RFEM 6, I recommend a laptop with an Intel Core Ultra 7 or Ultra 9 processor, 32GB to 64GB RAM, a dedicated NVIDIA GeForce RTX graphics card and a 1TB SSD.
If you regularly work with large finite element models, complex surfaces and solid elements, consider a 64GB or 128GB RAM configuration. For smaller projects, a well equipped 32GB laptop with a dedicated GPU should be sufficient.
