System properties - 2 CPU speeds shown?

I've just noticed the details in the attached screenshot.

Can someone explain why 2 speeds are mentioned? Googling didn't help

Must be nominal (designed) vs actual as 3D Jed said.

System Properties:


Speccy:

It's the speed at what the fastest your cpu can go, and the second is when your processor is idle and what it idles at. Usually.

It varies, I think it also depends if laptop or desktop.

Most modern CPUs will reduce its speed by lowering the multiplier and lower its voltage to conserve power when it is idle. Your CPU is currently running at 2.66GHz, but has a maximum frequency of 2.80GHz when under load.


The second speed usually refers to the actual speed of the processor, while the first is the "Rated" speed that the processor is designed to run at. You see this most commonly if the processor is clocked down to save power when idle. It is being word-wrapped to the second line because of the width of the window.

I am seeing different opinions however.

This has good info: http://www.directron.com/fsbguide.html

Thank you, guys.

I'm inclining towards the "idling speed" as described by andrew129260. Googling put this thread at the top!

It's a tower system. Device Management shows 8 cores at 2.80GHz. The BIOS shows:
BLCK 133.27 MHz and Turbo and non-Turbo ratios of 20.

If the figures did show rated speed and max speed in this system, what would cause the max speed to be less that the rated speed? What can I look at?

It all depends on the load on the system and the Power options you have set.
Mine is at a 100% all the time because I have a lot of cooling and I really don't care how much electricity it uses.
If the Max is set at (60%) at idle or light load you will get readings under the rated specs. Why your picture in the first post look that way I can't tell you. Could be a gigabyte motherboard.
My Windows show 3.7 - 3.7







This is what I run all the time. Idle or under load.

Core Speed Multiplier Bus Speed Temperature Threads
Core 0 4625.2 MHz x 37.0 125.0 MHz 24 °C APIC ID: 0
Core 1 4625.2 MHz x 37.0 125.0 MHz 29 °C APIC ID: 2
Core 2 4625.2 MHz x 37.0 125.0 MHz 30 °C APIC ID: 4
Core 3 4625.2 MHz x 37.0 125.0 MHz 26 °C APIC ID: 6

Could be wrong but to me it seems like normal and turbo ratings??
ARK | Intel® Core? i7-860 Processor (8M Cache, 2.80 GHz)

If you look at the specs you will see andas someone has already said probably down to what power you have it set to!!

As has been stated a few times, the higher number is the Stock Rated Speed, or frequency the CPU has been rated at by Intel. the lower number is the current frequency. Turbo speed isn't shown in System Properties. My turbo number is 3.8GHz, but...

Sorry I thought we were discussing the CPU which is the one I linked to the previous post - my mistake.
