What is an X3D processor, and is it worth it?

You may see X3D in the name of some AMD processors. These chips are made with gaming in mind. Here is what X3D means, when it is worth paying for, and when your money is better spent elsewhere.

What X3D means

A processor has a small amount of very fast memory built into it. This is called cache. It holds the things the processor needs most often, so it does not have to wait for the main memory.

On an X3D chip, AMD stacks an extra layer of cache on top of the processor. That is the "3D" part. Many games use the same pieces of information again and again, so this extra cache helps them run more smoothly.

When X3D is worth it

  • You want high frame rates. Frame rate is how many pictures a second the PC draws. Fast games and high-refresh screens need lots of them, and that puts more work on the processor.
  • You have a strong graphics card. A strong card can draw pictures very fast. Then the processor can become the part that holds things back, and X3D helps there.
  • You play games that like cache. Many strategy, simulation and competitive games benefit.

When X3D is not worth it

  • Your budget is tight. Spend on the graphics card first. It makes the biggest difference to how games look and run.
  • You play at high resolutions with a middle graphics card. Here the graphics card is doing most of the work, so a faster processor shows less.
  • You mainly work rather than play. For heavy work such as video editing, other processors can give more for the money.

The short answer

An X3D processor is a great gaming chip, but it is not the first thing to spend money on. Get the right graphics card for your screen first. If there is money left and you want the highest frame rates, an X3D chip is a good next step. Every PC we sell is built and tested on our own bench in Worcester.

Questions people ask

What does X3D mean on an AMD processor?

X3D means AMD has stacked extra cache on the chip. Cache is very fast memory right inside the processor. Many games like having more of it, so X3D chips are popular for gaming.

Is an X3D processor worth it?

It can be if you have a strong graphics card and want high frame rates. On a tight budget, a better graphics card usually helps games more than an X3D processor.

Does an X3D processor help every game?

No. It helps many games, some a lot and some hardly at all. It also helps less when the graphics card is the part holding the PC back, which is common at higher screen resolutions.

Is an X3D processor good for work as well as games?

Yes, it works as a normal processor for everyday tasks and work. But if you mainly do heavy work rather than gaming, a non-X3D chip can be as good or better for the money.
