Question about CPUs (4 vs 8 core)

post #1 of 5
Thread Starter 
A guy named "Sangeet Khatri" said just because a CPU has twice as many cores does not equal twice amount of power.

So I looked up the benchmarks of the FX4350 and FX8350, there both the same CPU except one has 4 cores and the other has 8 cores.

On cpubenchmark.net fx4350=5231 and fx8350=9078

Meaning the difference between the two is .735%

My question, is it a similar amount of performance increase in other CPUs with similar specs?

It depends on a lot of things naturally, and most of us can argue that to the grave.

For one, it depends on if the application is threaded to utilize all the threads that are available to it. Traditionally it has been one, but we are moving to 4-6 in some consumer level applications. There are also some other factors in play of course

No what I mean is, if there are 2 other CPUs that have the same design and specs but one is 4 core and other is 8 core.

Would it have the same performance increase...by 73.5%?

Yes and no, if your simply idling Windows/OS then not really

Only if the application can take advantage of the extra threads (if they are the same save for core count)

Unless someone can correct me otherwise?
