For most users, the GPU will be the bottleneck for Autocad's CPU utilization. In this benchmark, the worst case scenario was tested. Other testing included compressing a 200MB file over 2 minutes, editing a video clip with After Effects and drawing something simple like a box. The results are continually rising as the CPU usage increases.
Let’s start with a look at the charts. We have AutoCAD 2013 running on the Z77 platform and the same version of the software running on the X79 platform. Both versions of the software were run in a fully updated Windows 7 system, using the latest Windows 7 64 bit drivers from AMD and NVIDIA. The Graphical Settings tab of the video cards were set to Expert 1, while the OSD was set to widescreen, no scaling. The video cards were connected directly to the mATX motherboard, using a single DVI cable. The external power supply for the video cards was used to power a single Corsair AX1200i 1000W power supply.
The test settings are fairly straight-forward, but you should take note of how we are using the CPU. Benchmarking AutoCAD for 2D work can often mean using 100% CPU, but in this case we are only using Core 2 Duo 6100T CPUs. In other words, this is mostly a stress test for the GPU.
Columns that are entirely black indicate that there was no boost in performance. While all of the other settings were left on their default settings, performance was reduced to provide a clear line of comparison.
** In progress, make an online version of the file also so that SketchUp imports file and not need to start the app each time to import the file. This is also more secure than online version (CC BY-SA 3.0) and less exposed on the internet. d2c66b5586
