How to match a CPU and GPU to your games

Use the CPU decision guide for the platform shortlist and the expanded limit-diagnosis guide before changing an existing pairing.

Use frame times and like-for-like benchmark settings to judge the pairing. The GPU specification guide separates capacity, bandwidth and processing resources.

Match the CPU and graphics card to the screen and games, then spend where the system needs help. On an existing PC, a few repeatable checks can show whether a graphics upgrade, faster processor or simpler setup change will be most useful.

The named shortlists are processors for gaming and graphics cards for gaming. Use the complete gaming build to keep those choices balanced with power, memory and cooling.

Keep one workload fixed

Choose a representative game scene, resolution and preset. Note whether ray tracing, upscaling, frame generation or a frame cap is enabled. Changing those conditions can change which part limits the result.

For a new build, use reviews with clear methods. For an existing PC, run a repeatable scene and record behaviour before changing parts.

Use changes to test a suspicion

Lowering graphics load improves performanceCompare GPU upgrades at the intended settings.
Lowering graphics load barely changes performanceCheck CPU/game limits, caps and background work.
Performance falls after sustained playCheck temperatures, clocks and cooling before buying.
Long pauses alongside heavy memory pressureInvestigate RAM, storage and background applications.

These are diagnostic routes, not automatic component verdicts. Several limits can occur within the same game.

Pairing includes the surrounding system

A processor choice commits you to a supported board, memory and cooler. A graphics choice needs suitable power, space and display connections. Compare the installation totals.

Avoid paying extra for CPU performance that the GPU and chosen settings cannot use. Equally, a powerful GPU will not eliminate a CPU-limited target just because it costs more.

Use PC Builder to pair an AM5 CPU and graphics card and compare the whole build. The game helpers provide starting choices you can adjust around your screen and budget.

A useful buying record

Write why the CPU and GPU suit the intended workload, link the relevant tests and list the exact surrounding models. Add the complete platform and graphics costs together.

Use the main pairing guide and the compatibility checklist before ordering.
