Questions pertaining to CPU

shoob0x · Jan 17, 2014

I recently purchased a new Quad core CPU that is about 3.0 ghz to replace my 2.2 ghz quad core one. How much better will it be? How do I go about overclocking?

What are the models of each? You cannot compare CPUs directly on clock speed unless they are of the same family.

And better in which tasks?

Exactly, clock speed doesn't tell you anyting about the efficiency of a CPU. I've seen some CPUs with 2.0Ghz clock speed beat a 3.0Ghz because it is better optimized for the application.

Think about it like a car comparison. One is a tiny sport car with 200 HP and the other one is a heavy truck with 300 HP. The smaller car might beat the other one because it is more lightweight. Or even if the truck could beat it in a straigt line, the sport car will be ahead in curves beause it has better handling.

Same thing with CPUs, one CPU might take 20 steps to complete a particular task and another only 4 steps. So if the one with less clock speed is better optimized it might feel faster. And I'm not even talking about multi-core CPUs, having more cores is not necessarily a garantee it will be faster, because not every applications are optimized to support them. Some applications support only 1 core so even if you got 8, the other 7 will not be used. Bottom line, every application is different and might react differently for each CPU.

With the latest processors, clock speed means almost nothing anymore. You would need to provide us with the exact make and model of the old CPU and new CPU. It is very possible that a quad core 2.2 GHz CPU is actually faster than a quad core 3.0 GHz CPU. There are even dual core CPUs of lower clocks that are better than some quad core CPUs of higher clocks. It all depends on the architecture.

Alright, thank you
