Cinebench vs Geekbench is the benchmark debate every CPU shopper runs into, and the answer is that they measure different things — which is exactly why you should know what each one does before you trust either score. They are both good benchmarks, but they are good at different things.
What Cinebench measures
Cinebench renders a 3D scene using your processor, and it does it with every core at once. That makes it a pure multi-core test: a chip with more cores and more threads will score higher, almost in direct proportion. It is also a sustained test, which means it shows you what your chip can do when it is working hard for minutes at a time — including whether it throttles when it gets hot. If you render, encode or compile for a living, Cinebench is the score that matters most to you. It is the test most reviewers use when they want a clean multi-core number, and it is free.
What Geekbench measures
Geekbench is a broader test. It runs a mix of short workloads — image processing, text compression, machine learning, encryption — and it gives you two numbers: a single-core score and a multi-core score. That makes it much closer to everyday use, where a chip is asked to do many different things in short bursts. It also runs the same test on Windows, Mac and Linux, which makes it the easiest way to compare a desktop with a laptop or a phone. If you want one number that describes a chip’s general ability, Geekbench is the one to look at.
Where they disagree — and why
A chip can win in Cinebench and lose in Geekbench, or the other way around. A gaming chip with a huge cache, like the one in our Ryzen 7 9800X3D review, will shine in games and in Geekbench’s single-core test, but it will not beat a 16-core chip in Cinebench — because Cinebench is a core-count test, and the 9800X3D only has eight cores. Our 14900K vs 9950X comparison shows the same thing from the other side: the two flagships trade places depending on which test you run. Neither test is wrong — they are measuring different strengths.
Which one should you trust?
It depends on what you do. If you render video or 3D, trust Cinebench. If you game, browse and do a bit of everything, trust Geekbench’s single-core score, and check the gaming tests in our best desktop CPU for gaming guide. If you do heavy multi-core work, trust Cinebench and the results in our best desktop CPU for work guide. And in every case, look at more than one test — our CPU benchmarks explained guide and our how to benchmark your CPU guide both make the same point: one score is a clue, several scores are an answer.
The score that matters most
The score that matters most is the one that measures your work. A renderer should care about Cinebench; a gamer should care about frame rates; everyone else should care about Geekbench’s single-core number. Pick the test that matches your day, and ignore the rest.
The bottom line
Cinebench vs Geekbench is not a contest with a winner — they are two different tools. Cinebench tells you how fast a chip renders; Geekbench tells you how fast it is at a bit of everything. Use both, and you will know a chip properly. Browse our CPU benchmark guides and CPU comparisons to see the latest chips tested side by side.
One last tip: only compare scores from the same version of a test. Cinebench R23 and Cinebench 2024 scores are not comparable, and neither are Geekbench 5 and Geekbench 6. If you see two scores that look oddly far apart, check the version first — it is the most common reason a comparison goes wrong.
