Question CPU Spec - Difference from the shop claim to its real output?

[Dave Russo]

Does anyone know, if specs. such as computer speed are often lies? My computer claimed it can reach 4.8 but never goes over 4.67(though this is a minimal difference), why the difference from the shop claim to its real output?

Several factors can affect max clock frequency or boost. It can be limited in the BIOS or could be a thermal issue.
Usually maximum boost is limited to 1 or 2 CPU cores during light single thread loads.

If you are running an AMD system make sure your have updated the motherboard chipset driver to the latest version.

Use HWINFO64 to check what the max clock speed is after using the PC for a few minutes.

It is very unlikely that computer manufacturers deliberately lie about the specs of their products. However, there are several factors that can affect the actual performance of a computer component, including the quality of the components, the configuration of the system, and the workload running at the time of measurement. In the case of the CPU speed, it is possible that you are not seeing the maximum frequency due to thermal restrictions or power limitations. You can use software tools such as CPU-Z or HWMonitor to check the actual clock speed of your processor and compare it to the specifications. It's also worth noting that CPU performance can vary depending on the model and generation, and benchmarks are often used to compare the performance of different processors.

May not be applicable here but sometimes you might wonder if those Spectre/Meltdown mitigations might be affecting general cpu performance. I know it does a bit for my Coffee Lake cpu--a little bit. I now have these disabled in the Registry.

Is this little app still relevant? InSpectre

Variations in silicon might also be a factor, I guess. By the way, my cpu claims it can go to 5.0 GHz, but only on two cores at a time. And HWiFO64 does document that. On all cores, it hits 4.8 GHz.

As the others have said, it's most likely because of thermal limitation, also keep in mind there can be some deviation between same CPUs in the manufacturing process.
