Do You Actually Need a Dedicated Graphics Card?

A graphics card is one of the most expensive parts of a computer, so it is worth knowing whether your tasks will ever use it.

What graphics hardware does

Every computer needs something to draw the picture on screen. In many machines this is built into the processor and shares the main memory. A dedicated card is a separate board with its own fast memory and its own cooling, designed for heavy visual workloads.

You can skip it if you

• Browse, write, study and handle email.
• Watch streaming video, including high resolution.
• Use spreadsheets, video calls and ordinary photo viewing.

Modern built-in graphics handle all of that smoothly and use less power, which means a quieter, cooler, cheaper computer.

It is worth having if you

• Play recent 3D games at good settings.
• Edit video or animate regularly.
• Do 3D modelling, rendering or machine learning work.
• Run several large monitors.

Things to check before buying

• Your power supply must provide enough wattage and the right connectors.
• The case needs physical room and airflow.
• The monitor should suit the card, because a powerful card paired with a basic screen wastes potential.

Laptops are different

A laptop with dedicated graphics is hotter, heavier and shorter-lived on battery. Decide whether you truly need that performance while mobile, or whether a desktop at home is a better home for it.

Spend sensibly

A mid-range card paired with a balanced processor and enough memory gives better results than a top-tier card in an otherwise weak computer. Think of the computer as a team rather than a single star player.
