CPU Benchmarks for Gaming: What Actually Matters

CPU benchmarks for gaming matter — but only the right ones, and only up to a point: for a gamer, the number that matters is not a synthetic score but how many frames per second your games actually run at, and how smooth those frames feel.

Synthetic scores are a poor guide for gamers

A high Cinebench score does not make a good gaming chip. Cinebench measures how fast a chip renders, which is a multi-core job — while most games depend on a few fast cores and a big cache. That is why a gaming chip with a huge cache can top the gaming charts while scoring lower in Cinebench than a 16-core workstation chip. Our Ryzen 7 9800X3D review is the clearest example: it is the fastest gaming chip you can buy, but it is not the fastest chip in a render test. If you buy on the strength of a synthetic score, you will buy the wrong chip — see our CPU benchmarks explained guide for why.

The benchmarks that do matter for gaming

For gaming, the benchmarks that matter are the games themselves. Look at frame rates in the games you play, at the resolution you play at, and look at the 1% lows — the slowest 1% of frames — because those are what you feel as stutter. A chip with a high average and poor 1% lows will feel worse than a chip with a slightly lower average and smooth lows. Our best desktop CPU for gaming guide and our best gaming CPUs ranking both use real game tests for exactly this reason. The 3DMark CPU Profile test is also useful, because it measures your chip at different thread counts — which is much closer to how games use a CPU than a single all-cores score.

Resolution changes what the CPU does

At 1080p, the CPU is the limit: the graphics card finishes each frame quickly, so the CPU’s speed decides the frame rate. At 1440p, the two are more evenly matched. At 4K, the graphics card does almost all of the work and the CPU barely matters — a mid-range chip is enough. Our guides to the best CPU for 1080p gaming, the best CPU for 1440p gaming and the best CPU for 4K gaming break this down, and our CPU bottleneck guide will help you work out whether your CPU is holding back your graphics card.

Cache, single-core speed and 1% lows

For gaming, three things matter more than core count: single-core speed, cache size and the smoothness of the frame times. The 9800X3D’s stacked cache is the reason it leads the gaming charts, and it is why our single-core vs multi-core benchmarks guide tells gamers to watch the single-core score. A mid-range chip like the Ryzen 5 9600X or the Core i5-14600K is fast enough for most gamers — and the money you save is better spent on a better graphics card, which is what actually decides your frame rate at 1440p and above.

What about esports?

Competitive games are the most CPU-hungry of all, because they run at very high frame rates on purpose. Our best CPU for esports guide covers that side of things — and if you play at 240Hz or more, the CPU matters far more than it does at 60Hz.

The bottom line

For gaming, ignore the synthetic scores and look at real frame rates, 1% lows and the single-core score. A mid-range chip with a good cache and fast cores is all most gamers need. Browse our CPU benchmark guides and gaming CPU picks to find the chip that fits your games and your monitor.
