What is the Best iMac Choice for SketchUp 2020?
Being aware that SketchUp (still) utilizes only ONE processor of the now commonly available multi core chip configurations, I am contemplating an iMac upgrade. I have heard that the Video Graphics card “speed/capacity” is very important to SketchUp performance. I am committed to staying in the Apple universe, so one dilemma I face is that while the current iMac lineup offers slightly higher processor speeds, the iMac Pro offers slower processors (w/ more cores, which don’t help), but much bigger/faster Graphics Cards …
I need to figure out which is more important to the total SketchUp experience, processor speed or Graphics Card capacity/speed!
For a base line comparison, I am currently running SketchUp Pro 2018 on my iMac 27” Core i7 4.0 GHz (5K Late 2015) w/ 32 GB RAM and a Radeon R9 M395X w/ 4GB of GDDR5 memory.
Despite lean file sizes and best modeling practices/work flow, I still get the “spinny wheel” frequently while using Layout.
- Which is more important, the “base” speed of the processor or the “turbo boost” speed?
For instance, is 3.7 GHz w/ turbo to 4.6 GHz better than … 3.6 GHz w/ a turbo of 5.0 GHz?
- When and how is this turbo boost triggered? Does it run for a whole task/demand cycle, or is it strictly “temporary”?
Video Graphics Questions:
How much of a difference in SketchUp performance will there be between the following two Graphics Card options:
Radeon Pro 580X w/ 8GB of GDDR5 memory. (Currently available iMac 27” 5K)
Radeon Pro Vega 48 w/ 8GB of HBM2 memory. (Option, + $450, current iMac 27” 5K)
And, if the Video Graphics speed/capacity is really of paramount important to SketchUp performance, how dramatic would the following option be?
- Radeon Pro Vega 64 w/ 16GB of HBM2 memory. (Currently available iMac Pro 27” 5K, but it costs lots of extra $$).
Regarding the above iMac Pro 27” 5K option - the downside of this choice is that it’s paired with a maximum processor speed of only 3.3 GHz w/ a turbo to 4.2 GHz). So, trade offs?
The iMac Pro choice will also cost me about $3K more, so I really need to believe this processor/graphics choice is superior …
So, it appears that my choice is between a faster processor paired with only an 8GB video card (Currently available iMac 27” 5K), or a slower processor paired with a bigger/faster Video Card (Current iMac Pro 27” 5K).
Any help or advice on the various iMac upgrade choices to best run SketchUp would be most appreciated!
