Help Me Choose: Intel® Processor

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. In general, a higher core number indicates higher performance when comparing the same type of processor, e.g. a core i7 will perform better than an i3.

Upgrading a processor after you purchase your computer can be costly and difficult. Because of this, we recommend that you choose a processor with enough performance to meet your needs well into the future.

If you want to run multiple applications at the same time, download and edit high-definition (HD) videos, convert media, and play video games on your PC, choose the Intel® Core™ i5 or i7 processor.

If you want to save a little money but still be able to view photos, movies and media, and accomplish everyday tasks like word processing, email and web browsing, choose the Intel Core i3 processor.

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 graphics performance versus previous generations.* View your photos, movies and media in stunning clarity — even when you’re on the go.
• 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.

IntelWhich processor is best for me?
When it comes to choosing a processor, keep in mind that a higher number generally indicates better performance. Available in three performance levels, Intel® Core i3, i5 and i7 processors are designed to deliver faster, smarter performance. Depending on the number of cores within each processor, you can get more multitasking capability, extra speed or advanced media capability.

When choosing a multi-core processor, it helps to know what a core does.

A processor core channels the data that carries out the commands required to run applications on your computer. The more cores you have, the more lanes that data can travel on, like a highway with multiple vehicle lanes.

Older, single-core processors can only process one thread at a time. When processing more than one task, such as surfing the web while playing an MP3, single-core processors alternated between each thread, processing a small chunk of data each time. This often resulted in a noticeable system slowdown.

Dual, quad and six core processors are available to give you the performance you need to get things done faster. Dell offers the latest 4th generation Intel Core processors (Core i3, i5 and i7) as well as 2nd and 3rd Gen, so you can be sure there is a Dell system that will meet your needs.
