Does an extra 0.16ghz make a difference? if you have two 4 core processors both 1.6ghz but one has a boost clock of 2.4 and the other is 2.56 does it really make much of a difference?

depends but it will be a small differance

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

well, calculate the percentage of your total clock speed that is, and that'll be about the difference in cpu speed you'll see.

 

that said, if your workload doent need the full speed of the lower one of the two anyways, it'll be essentially a zero difference in real-world tests.

It's an about 6.7% increase in maximum clock speed. So --everything else being equal-- that is what you will gain in performance in a best-case scenario.

 

In any task where the CPU is not boosting there will not be a difference, and in any situation where it's not at 100% load for prolonged periods the difference will be negligible. (For instance: if your CPU is boosting to the max for only 5% of its processing time, that reduces the average performance gains to about 0.3%.)

except that boost clock only kicks in when the cpu has room to spare e.g when not under full load and can boost cores up.

which is in far more scenarios than you may think ;)
