I ran a rendering test with 2 systems.
Puget Intel Xeon CPU E5-2680 v3 2.5GHz 2 processors 128GB RAM
Origin Intel i7-3770K CPU 3.5 Ghz 16GB RAM
windows 7
Maya 2015 SP5
Origin older cheaper computer 1.28 times faster mental ray and software render
All the software settings are the same
Any suggestions to get the Xeon faster?
