system recommendation for tough performance

christian graf
Dear all,

thanks for this nice piece of sw. My old PC died, so I am in need to build a new one.

Some of my objects render minutes (still tuning $fn, $fa, $fs), but beside of this I would be happy if I can get some recommendation please:

- CPU: amd ryzen 7 1800x or intels i7 8700k ?
- GPU: amd vega 56 or nvidia 1070TI?
- Memory: 16GB, DDR4-3200 or DDR-3600?


If someone can share some experience or recommendation that would be much appreciated


thanks

christian

In the current release, fast memory is critical for large renders. Boolean operations on sufficiently large meshes are memory bound, not CPU bound. Get the fastest memory, that's the most important.

In a future release, multiple cores will help, but not today.

Fast CPUs help for rendering smaller meshes, or for script evaluation, in rare cases where you do heavy computing using algorithms written in openscad.

I don't think the GPU is critical. Any modern GPU is fine. The GPU is only used for preview.

works just great on my laptops integrated graphics (intel HD5500)

I second the recommendation for fastest memory*.

I'm currently running OpenSCAD in a remote computer because its RAM is four times faster than my (newer) computer at home, and the experience is sooo much better.


(*) Meaning what CPU-Z calls "NB Frequency"

Raw single core performance, large CPU cache, fast memory.

I'd also go with a large screen (4k), not for performance, but for the
screen space. More room for code, while still having a large preview.

Things you can skip on (but which you'll probably want for other
reasons...):

* Large/fast disk.

* Lots of memory. 16 GB is plenty enough.

* Good graphics card. If you go for 4K, make sure your card supports 4K at
60 Hz, though, or it'll be downright painful.
