The system performance is dependent on the entire system configuration at both hardware and software levels. We recommend you double checking the software system requirements in order to see which processor might be better.
Furthermore, at the following site you will be able to see the differences between both processors: http://ark.intel.com/compare/33910,29765

Keep in mind the more threads supported by the processor, the more threads can be ran at the same time without degrading the system’s performance.
