That is what I figured, and yes I knew that the CPU and GPU sort of go hand in hand, however right now performance is lacking in the modeling area of my work, not so much rendering.
Would installing sketchup on an SSD also help the speed or does that not matter as much as the CPU?
Using an SSD will reduce the start up time of SketchUp and if you also save and load your files to the SSD it will reduce those times. It will have no effect on general performance while SketchUp is running.
That recommendation is based on two things: first, the NVidia GeForce series has generally the best and most stable OpenGL drivers, and second, very high-end gaming or specialized 3D cards generally don’t provide anything extra that SU can use so they are not worth the extra money if SU is all you are doing.
I’m negative too in that case 
My grievance was more about Autodesk products, which runs poorly despite powerful hardware.
No particular issue in Sketchup 2017 when panning and orbiting, I can indeed observe improvement since sketchup 8 all along the years.
Some years back Autodesk shifted from using OpenGL acceleration to using Microsoft’s DirectX. IMO its applications lost some performance in the process.

Ironic, since DirectX was supposed to be newer and greater (as well as proprietary)! I wonder if the same would be true of Apple’s newer proprietary graphics library?
ArchiCad 20 for Mac is multithreading
Why not multithreading for SU when Archicad can do it?
ARCHICAD multithreaded?
Yes, ARCHICAD takes advantage of multiple cores / processors in various computationally intensive areas such as:
2D drawing in case of projected 3D elements, and other special cases,
Generation of Sections and Elevations,
3D generation, loading and saving,
Drawing updates,
Background conversion of opened 3D based windows,
Placing PDF files as drawing (visual feedback when positioning the drawing),
Rendering,
File saving with data compressing option,
Managing Autosave.
And in addition, ARCHICAD takes better advantage of the graphics processor in your display adapter.
(Until ArchiCAD 12, ARCHICAD was not multithreaded as a whole.)
On the Server side: the BIMcloud Server is multithreaded also.
Yes, typical from Autodesk… Acquisition just to put their branding on top of the original code, losing features and stability in the process (ROBOT is the best example I can think of).
What about Vulkan API ? Multi-platform, not yet multi GPU but it’s getting there with heterogeneous GPUs, more open than DX…
It’s mostly marketing hype. Read the small print. Yes, when you have several view tabs open at the same time, Archicad can update the invisible ones using some multithreading, but there is no more multithreading in the actual real time modeling process than before. And the technique behind is irrelevant if it doesn’t translate into user experience. I don’t find Archicad 20 any faster than version 18 (it has other good new features, though). I use it daily.
SketchUp has only one window. Sketchup doesn’t have a separate 2D or sheet workflow, everything happens in the same 3D environment.

Hi all,
In dec 16 I started a similar thread:
I seemed like we all agreed that
But I still can’t help thinking “What-if” …
So, if we focus deep into the SU system’s workflow here, isn’t it like this:
There a only TWO basic activities: A.Changing the model (for instance moving a chair in a room) and B.Changing camera and rendersettings (position,zoom,pan,fog etc)
In real time A and B are split up into micro-steps after which a re-RENDER is performed. So it is the render that makes a very big model lag so much after every little change, not the change itself.
This makes me think that if SU incorporated a multithreading render engine, this time critical render-step could be boosted very,very powerful. What if?

Hi.
At work I install su2015 on different hardware:
Xeon 10C/20T 2687 v3
Xeon 6C/12T
i5
i7
The i7 is the fastest under su due to better performance with only 1 thread.
Just after, in that order: i5, Xeon 6C, Xeon 10C.
The 10C is the slower under SU.
But it’s the fastest under Artlantis.
We bought the 10C with a Dell Precision at 4000 € excl. VAT with a poor Quadro K2200. I replace it with a GTX 680.
With heavy scenes (20 millions faces) it become a little complicated to work.
SU use a lot of gpu ram to open a file.
Speed also depends on your knowledge of SU.
Fast styles are not just a little green bullet. If you are not using this styles to work or at least using it on your opening view you can wait 15 min to open a heavy file.
If you need more details I would be happy to share. I’m using my phone to answer ^^
