Dear all,
For a change a complete new topic --> Hardware ;-)

I have two workplaces. On one of those -some weeks ago- I changed from
a very old Intel Core i5 Dual core to a newer Core i5 6300HQ with 4
cores. The new Laptop also has 16 instead of 8 GB RAM. The difference is
great and working makes fun again.
I run a kind of Ubuntu (Zorin OS) and due to my feeling renderings in
Openscad are the most and important challenges in my whole computer work.

Now I think, if e.g. one of the new Intel ATOM or Celeron, which even
have 4 cores, could maybe also could increase the performance. The new
workplace should palpable be better than the 12 years old HP notebook
with Intel Core i5 with dualcore.
And as I have a monitor on my second workplace I think about a kind of
Mini-PC which I can mount on the backside of the monitor.

does anyone of you have experiences with such devices?
Thanks Karl

Karl:

For OpenSCAD, you want the fastest core speed you can; multiple cores
are not currently used by OpenSCAD. I always try for a 4 GHz machine.

With the snapshot version and the Manifold geometry engine, that
is not 100% true anymore.

However a focus on fast single core speed, plenty of memory and
a very very fast memory interface is probably still a good guide.

ciao,
Torsten.

Where can I read more about "the Manifold geometry engine" please

Depends on what you mean. If you just want the improved speed and
depending on the model some nice use of multiple cores then use
a very recent snapshot version and enable the experimental feature
"manifold" (Edit -> Preferences -> Features).

The library was started by Emmett Lalish who maybe be known by
some people by the amazing designs he has on Thingiverse

https://github.com/elalish/manifold/
http://www.thingiverse.com/emmett

One of his heart gears designs is sitting in my hallway, printed
many years ago on the good old wooden Ultimaker v1 which I don't
even own anymore :-).

ciao,
Torsten.
