Best CPU for Office Use in 2021, Tested & Ranked

When it comes to finding the best CPU for office use, you really don’t need to consider high-end processors at all. Even a CPU with 4 cores could be enough to deal with office-related tasks like MS word, Excel, Outlook, etc. However, a high-end processor can handle the toughest workloads in less time while increasing your productivity.

As you know, there are two chip manufacturers in the market, Intel and AMD. The Intel CPUs are better to know for their single-core performance whereas AMD shines in the multi-core. Applications like MS Office and Outlook are single-threaded, so having an Intel CPU can give you more edge in performance.

AMD on other hand is cheaper than Intel but delivers almost the same kind of performance when dealing with MS Word, Outlook, etc. Also, most of the AMD chips are equipped with built-in graphics cards, this eliminates the need of buying an aftermarket GPU that you really don’t need in an office computer.

The processor that you need for your small business depends on what kind of applications you will interact with. It’s better to go for a CPU that can easily handle demanding applications and gives you an edge in multi-tasking without crashing or lagging.

Most people think that CPUs that are ideal for gaming can also perform very well in the office or small business environments. However, keep in mind that the gaming CPUs and work CPUs are different chips. So we’ve tested and compiled the list of CPUs that are the best bang for your buck when it comes to business workloads.

Before You Go for Productivity-Based CPUs

Consider the following:

  • Know your needs: If you are dealing with apps that make use of more cores/threads, then AMD chips could be the right fit for you. However, if you are dealing with single-threaded programs like MS Office, Adobe Acrobat, Outlook, then Intel CPUs can give you more edge in dealing with them.
  • Advanced CPUs: Older CPUs might save you a lot of money but also limit your chances of upgrade. Moroever, the motherboards that support old generation CPUs are expensive to get. So, it’s better to go for latest-gen CPUs that are at least future-proof for few more years.
