Help Me Choose: Intel® Processors

The processor or CPU processes the critical information and instructions that make your computer perform. Think of it as the system’s brains, enabling it to run the applications and other operations.

The speed at which your system runs programs, loads images and downloads files depends in part on the processor. Bandwidth, clock speed and the number of cores in the processor all help determine processor performance. As a general rule, a higher number indicates higher performance.

Dell recommends that you choose a processor with enough performance to meet your needs well into the future.

Depending on the processor you choose, you can get more multitasking capacity, extra speed on demand, and breakthrough performance on digital media consumption and creation.

Today, the latest Intel® processor technology is 4th Generation Intel Core™. The completely redesigned 4th Gen processors feature huge improvements over 2nd and 3rd Gen processors, including:

• Efficiency: Spend less time looking for an outlet and more time getting things done. Intel’s latest 4th Generation processors are more power efficient than ever without sacrificing performance.
• Graphics: 4th Gen Intel Core processors provide up to 2x better integrated graphics performance versus previous generations.*
• Performance: With up to 13 percent better performance than previous generations,* 4th Gen processors give you enhanced power and speed you need to accomplish tasks.
