About this tool
Last updated
Processor Benchmarks is a free, browser-based tool built by PC Tester, the diagnostic tool suite founded by Adeel Farooq, to make CPU performance data easier to browse, compare and understand. It brings single-core and multi-core scores for desktop, laptop and server processors into one page, and lets you test your own computer without installing anything.
Why PCTester built it
Choosing a processor usually means opening a dozen tabs: one for a review, one for a spec sheet, one for a benchmark list, and another for a price. Raw benchmark tables are accurate in spirit but hard to read when you only want to know whether a chip is meaningfully faster than the one you have. PCTester built this tool to put the useful numbers, the key specifications and a clear visual comparison in a single place, with no sign-up, no downloads and no clutter.
What you can do here
- Browse the leaderboard. Rank processors by single-core or multi-core score, and sort by cores, clock speed or architecture.
- Filter and search. Narrow the list by brand (AMD, Intel, Apple, Qualcomm), segment (desktop, laptop, server) and core count, or search for a model by name.
- Compare two processors. Pick any two CPUs on the Head to head tab and get a full comparison page with score bars, percentage differences, efficiency figures and a plain-language verdict.
- Test your own device. The built-in runner executes four real compute workloads (prime sieve, Mandelbrot, SHA-256 rounds and matrix multiplication) on your CPU and gives you a browser-only score.
- Export the data. Download the current filtered list as CSV or JSON for spreadsheets or your own analysis.
How it helps you
When buying or upgrading, the tool shows how much faster one processor is than another as a percentage, which is easier to judge than two large numbers. If an upgrade is only a few percent faster, you can keep your money.
When matching a chip to a job, single-core and multi-core scores tell different stories. Single-core performance drives how responsive everyday apps and many games feel. Multi-core performance matters for video rendering, compiling code, 3D work and servers. Seeing both side by side helps you pay for the one your work actually uses.
When thinking about power and heat, the comparison page includes score per watt, a rough guide to efficiency that matters in laptops, small PCs and data centres.
When checking your own machine, the runner gives you a repeatable way to see whether a driver, cooling or power-plan change made a difference.
How to read the scores
A higher score means faster. A chip scoring 3000 in single-core is roughly 20 percent faster on one thread than a chip scoring 2500. Multi-core scores do not scale perfectly with core count, because memory bandwidth, power limits and software that cannot use every thread all hold results back. That is why a 96-core server chip does not score 96 times higher than a single core.
Methodology and sources
Single-core scores come from the Geekbench Browser processor benchmark chart (browser.geekbench.com), as of October 2026. Where a processor appears more than once, the highest score is shown. Base clock and core count come from the same chart.
Multi-core scores, launch prices, TDP, boost clocks and release dates for the leaderboard models are approximate estimates and are not Geekbench Browser results. Chips without a multi-core score show single-core results only. Prices are launch list prices in US dollars, converted at fixed rates and excluding tax.
The in-browser benchmark is a separate measurement on its own scale and is not ranked against the figures above.
How much to rely on the numbers
Real results vary with cooling, memory, operating system, power settings and driver versions. They are meant for orientation and comparison, not as official figures. For exact, current results, check the official Geekbench Browser at browser.geekbench.com.
The in-browser benchmark is different. It measures your device live using JavaScript running in background threads, so its score is on its own scale and cannot be compared directly with native Geekbench results. It is best for comparing one device against another, or one configuration of your own machine against another.
Privacy
Everything runs in your browser. Your benchmark result is saved only on your own device and is never uploaded.
