advanced rendering for AutoCAD
Is there a huge difference between 4-Core and 6-Core machines if Im using the following to do my work :
I know RAM is king but how much impact will the Core Count have since I believe the AccuRender Engine differs from Max.
regards and thanks
With rendering, the two main factors are number of cores and speed of processors.
4 cores running at 3.0GHz will render roughly twice as fast as 2 cores running at 3.0GHz.
So if your 6 core option runs at the same frequency as your 4 core option, renders will run 1.5 times faster.
RAM is only used for storing the CAD file in memory. It does not affect the rendering speed.
Thank you Peter, I really appreciate it.
Basically I use a very crude but effective method for determining the fastest machine for rendering: multiply the number of cores by the clock speed.
So 8 cores running at 1.6GHz would be roughly equal to 4 cores running at 3.2GHz.
It's not strictly true, but it does give a good indication.
I'll take your experienced technique for granted!
Thank you Peter!
Another question :
Would you go for 12 GB RAM with a 2GB Video Card or
24 GB RAM with a Dual DVI 256MB Graphic Card ?
Again, we're talking CAD/NxT/Pshop & Indesign.
Neither will make any difference to rendering speed and you'll be pushed to use 12Gb RAM unless you're dealing with extremely large and complicated 3D models.
Ideally, use a graphics card that is recommended with your software such as nVidia Quadro for AutoCAD, though it's not strictly necessary.
Thank you Peter, I really appreciate your inputs.
