frequency difference to make noticeable difference in a CPU?

[OCD-FREAK]

hello everyone,

 

how much frequency difference does a CPU need to make it faster/noticeable than one another?

 

like for example how much of a "real world" difference does a 300MHz difference make in a processor ?

 

please elaborate in your answers.

 

thank you all

depends on a lot of things but general a higher base clock will also yield better OC but that depends on the CPU in question (ie K cpus are better for OC than standard CPUs)

 

if you could show the two cpus in question it'd be an easier yes or no

It depends on what you're doing. If the program or game you're using scales perfectly with higher cpu clock speed, a 10% increase should result in a 10% increase in performance provided there isn't bottleneck elsewhere. In some situations, the bump in clock speed may make the difference between an unplayable or passable experience.

I mostly noticed it while streaming or editing video. In gaming it depends on what you upgrade from. For clocks I didn't notice the ca. 15% oc that I have now. But it also could be that I just got too used to it

iam comparing the intel core2quad Q9100 vs core2extreme QX9300. i will never overclock any of them

i will be using the laptop for heavy general multitasking and workstation - no gaming

ignoring the OC speeds which i think shouldn't be on this list, the qx is noticeably better in other parameters as well such as cache speed and size and said cpu is also unlocked which makes easier to OC (if you want to) so i would get the qx if i had to chose between these two unless its a steep price difference

The q9100 is 15$ and the qx9300 is 45$ the only difference between them is 270Mhz which is that of the extreme. I will not overclock any of them

300 MHz increase on a 300 MHz cpu would be a noticeable improvement, but 300 MHz on a 4.7 GHz cpu not so much

we are talking about core2quad Q9100 vs core2extreme QX9300. the only difference between does two quads is that the extreme is just 300MHz more than the Q9100.... so what you think ?

Sorry, I answered a bit hastily. I'm not familar with these cpus, but it seems to me that the main difference is that the QX model can be overclocked. I would say there is no practical difference between them...

Here's a pretty good performance comparison article I saw: https://www.notebookcheck.net/Comparative-Review-of-the-Intel-Core-2-Quad-Notebook-CPUs.13426.0.html

That answer is very subjective and in most cases probably even a placebo, i mean if i had to make a guess i'd say 300mhz or more might improve the snappiness of a system. Back in the day 25mhz made all the difference lol
