The central processing unit, or CPU, performs the critical tasks that make your OptiPlex perform. The speed at which your system runs applications, processes data and renders images depends in part on the capabilities of the processor.

You should choose a processor with enough performance to meet your long-term business needs. Bandwidth, clock speed and the number of cores in the processor all help determine processor performance.

Dual-core processors place two cores on a single processor giving you more power to multitask. For example, you can run virus protection, download files and run applications — all faster than with single-core processors.

With four execution cores, the Intel^®  Core^TM  2 Quad processor blows through processor-intensive tasks in demanding multitasking environments and makes the most of highly threaded applications.
