AMD vs Intel: Which desktop processor is right for you?

The processor – sometimes called the CPU or Central Processing Unit – is the brain of the PC, the place where much of the computational work is done (along with the GPU or Graphics Processing Unit).

The faster the processor, the faster the PC will usually be.

Take two PCs, one powered by an Intel processor and another by an AMD chip. Put them side-by-side, and functionally you will not see a difference.

They'll both run Windows 11.

They both run your favorite Windows applications.

They'll both run the games you want to play.

And unless you were to dig into the system settings (or you can open up the PC and take a peek at the CPU), you're unlikely to be able to tell which PC is being powered by what processor.

It doesn't matter

But that said, there are differences

Just because processors made by AMD and Intel are functionally similar, that doesn't mean there aren't any differences.

There are a lot of differences, from price to performance to which runs the coolest.

Let's take a look at some of the main differences.

Performance is something that can be measured, so you'd think this question would be easy to answer, but it depends on what you want to do with that power.

This is where things get murky, because it's not just down to the speed of a processor.

It's easy to think that the fastest processor is always going to be the best, but it's also important to consider price, and finding that sweet spot of price vs. performance.

A good place to look for a processor for productivity and content production is in the mid-ranges of price, because these give you the best bang-for-the-buck. And this mid-range is dominated by Intel. 

CPUs run off electricity, and the more they use, the hotter they get. On desktop systems this means needing to fit bigger — and noisier — fans to keep the system cool.

So, if you want a quiet PC, you want an efficient CPU that runs cool, and on the whole, this will be an AMD processor. This company has made leaps and bounds over the past few years in improving efficiency.

How do you tell how efficient a processor is?

Every manufacturer publishes a TDP (Thermal Design Power) for its CPUs and this is a measure of the maximum amount of heat generated by the chip. If you want to find this information, Google is your best friend – do a search for the name of the processor and add “TDP” and you'll find this information.

The higher this number, the more heat that will need to be dealt with.

It's easy to think that all you need to build a fast PC is a fast processor.

This is incorrect.

A fast CPU is just the start, but without a fast motherboard, fast graphics card, and plenty of fast RAM, you can have all sorts of performance bottlenecks that can really impact the overall performance of the system.

A fast CPU is just the start. There's no point dropping hundreds of dollars on a fast CPU if the other parts won't be able to keep up.

Don't overspend on a CPU and then cheap-out on the other parts.

These companies have had the market to themselves for a long time. But over the last few years, a new player has entered the market.

Apple.

The M1 and M2 Apple Silicon processors are blowing Intel and AMD out of the water both in terms of performance and efficiency, creating chips that are incredibly powerful and energy efficient enough to run in laptops off battery power.

Apple Silicon is going to get faster and more efficient and is going to present challenges that Intel and AMD are going to have to face just to be able to allow PCs to keep up with the Mac.
