Processor speed directly affects a computer’s performance. High speeds mean better performance. However, you only get the clock speed, and the core counts info in the retail box.
Then does the clock speed mean your CPU speed? Or some other aspects determine your overall processor speed.
To clear up this confusion, I will show you all about measuring your processor speed in this article, with what they indicate about a processor’s performance.
So let’s jump in.
How Can You Measure Your CPU Speed?
There were times when clock speed determined how fast a processor would perform. But after introducing multi-core technology, we measure CPU speed based on the combination of cores and clock speed. However, users can get the best CPU speed measurement using benchmarks.
The fact is, it’s impossible to measure CPU speed using a normal stick or meter ruler. Because factors like clock speed, number of cores, threads, transistor size, architecture, etc., affect a CPU’s overall speed and performance.
Your CPU architecture also impacts your overall CPU Speed. That’s why you need to know your processor speed. Follow this article to know your processor architecture.
But does GHz matter in CPU speed? Well, you need to read that article to know for sure.
In this part, I will discuss some widely accepted and reliable benchmark tests that provide a good understanding of the processor’s speed. You can use them to determine how fast your CPU is.
These are some benchmark tests to measure your CPU speed:
- Cinebench R15.
- Cinebench R20.
- Cinebench R23.
- Geekbench 5.
These benchmarks will help you to determine your CPU speed as well as its overall performance. Common users like you and me can make purchase decisions using this data.
In this part, I will show you how you can measure your CPU benchmark using Geekbench 5. The steps are quite similar to other benchmarking apps. This test will help you determine your overall CPU speed.
Follow the steps to measure your CPU speed using Geekbench 5:
- Download and install the Geekbench 5 from the website.
- Open the program.
- Click on the Run CPU benchmark option.
After completing the steps, your default browser will open automatically and show you the results. You will get a clear idea of your overall CPU speed from there.

Does Clock Speed mean CPU Speed?
Well no. Clock Speed is important to evaluate CPU speed, but it does not solely determine how fast your CPU is. Your CPU’s clock speed determines how many cycles your processor completes per second. But for multicore processors, each core has its processing capabilities.
What you see in a retailer CPU packet is the clock speed of a single core. Single-core performance determines the strength of each core in a CPU. Meanwhile, multicore performance evaluates a CPU’s overall performance when all cores work simultaneously.
And the average between both Single-core performance and multicore performance determines your CPU’s overall speed.
Now, I will compare different processors with the same clock speed. It will help you to understand the difference between clock speed and CPU speed.
Let’s see the comparison between Intel Pentium G7400 and Intel Core i3 10105:
|Comparison||Intel Pentium G7400||Intel Core i3 10105|
|Clock speed||3.7 GHz||3.7 GHz|
|Cores||2 (Threads: 4)||4 (Threads: 8)|
|Cache||L1: 160 KB|
L2: 2.5 MB
L3: 6 MB
|L1: 256 KB|
L2: 1.0 MB
L3: 6 MB
|Geekbench 5, 64 bit (Single-Core)||1442||1168|
|Geekbench 5, 64-bit (Multi-Core)||3164||4501|
As you can see, the Intel Core i3 10105 and Pentium G7400 both processors have the same clock speed, but the core counts are different.
That’s why the Geekbench benchmark score differs in multicore. And Intel Core i3 10105 is faster than Pentium G7400.
Also, the Intel Core i3 10105 has a turbo-boost facility which helps it to perform better. But what is a boost clock speed? Check out our article base clock vs boost clock to get in-depth knowledge.
But when comparing the same generation Intel i9 processors 12900 and 12900K, the clock speed will matter.
Because other variables are the same in the same gen processors.
So in summary, we can say clock speed only matters when comparing CPUs within the same generation. Comparing different generations based solely on clock speed is not effective.
Then which one should you give more importance to, CPU cores or clock speed? Read the following section to know for sure.
Which One is Better: More Cores or Higher GHz?
The answer depends on your purposes and CPU workload. More cores can handle more tasks simultaneously, while higher GHz means a faster processing speed for a single core. So you need a multicore processor with high GHz for the best performance.
Many CPUs have multiple cores, meaning one chip contains several processing units. A single 5 GHz chip is typically faster than two 2.5 GHz chips.
However, to compare a quad-core chip at 3.6 GHz and a six-core chip at 3.2 GHz, you will need benchmarks. Otherwise, you won’t be able to compare these processors.
But in general, if you run multiple programs simultaneously or use software that uses the multi-core to run, a CPU with more cores, but low GHz will perform slowly.
To know more about it, check out our detailed discussion on how many CPU cores you need.
Is a 3.0 GHz processor fast?
Yes. A 3.0 GHz processor cycles 3 billion times per second. It’s fast enough for the average office worker.
What is good processor speed?
Usually, the right processor speed depends on its primary use. A processor with a 3.5 GHz to 4.0 GHz clock speed is better for gaming and editing.
How many cores should a good CPU have?
Good CPU cores numbers depend on the purpose you will use the PC for. 2 to 4-core CPUs are enough for usual usage, but for editing work, you should get a 6-core CPU.
In short, processor speed determines how fast your CPU will carry out tasks and run applications. It’s not just the clock speed of your CPU. The combination of clock speed, the number of cores, threads, transistor size, and architecture determines the overall speed of a CPU.
