Choosing Between Intel Core i9-14900KF and AMD Ryzen 9 7950X for Large Archicad Projects

[Tracado Regulador]

Hi everyone,

I’m currently deciding between the Intel Core i9-14900KF and the AMD Ryzen 9 7950X for my next workstation, and I’d appreciate some feedback from anyone using either of these CPUs with Archicad.

My workflow involves large project files (around 3 GB) with a high Level of Detail (LOD) and Level of Information (LOI). I often deal with complex models, heavy 3D geometry, and extensive BIM data, so I need a processor that remains stable and responsive under heavy workloads.

From what I understand, Archicad relies mostly on single-core performance for most modelling operations, which might give the Intel chip an advantage. However, the Ryzen 9 7950X offers excellent multi-core performance and efficiency, which could be better for multitasking, rendering, or running several processes in parallel.

I’d really like to know how both CPUs perform in real-world Archicad usage:

• Does Intel’s higher single-core speed make a noticeable difference when working with large models?

• Is AMD’s stronger multi-core architecture more beneficial for teamwork, exports, or rendering?

• Any issues regarding thermals, stability, or compatibility with Archicad?

Any insights, benchmarks, or personal experiences would be greatly appreciated.

Thanks in advance,
David Maciel

I checked the single-core and multi-core performance of both:

https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+9+7950X&id=5031

Based on that, yes, the Intel is about 10% faster in single-core, while the AMD is a bit faster in multi-core.

Since for Archicad, and even if you run many processes, single-core performance is more important.

I plan on buying a new desktop next year, and I will choose the CPU with the best single-core performance I can afford.

This is exactly the problem with Archicad's performance.

After all these years of development Archicad unfortunately still relies on one core while models and design data become more complex and heavier.

We get AI assistance while the speed during all the update processes (foreground and background) becomes slower and slower because gradually we add more and more information to the model.

It would have been really useful and interesting if there was an official announcement from Graphisoft if there are any plans for a real multi-core support at least in the near future. That will make everyone decide at what type of hardware we should invest.
