Hi guys,

When comparing processors that have a similar clock speed but different # of cores, does it mean that the (relatively) same amount of processing power is spread amongst more cores?Comparing the AMD FX-4300 (4 cores at 3.8Ghz) and the FX-6300 (6 cores at 3.5Ghz), I want to figure out if the 6 core has less computing power per core. So all other things equal, if i'm running a program that uses 4 cores, which processor would give me better performance?

Also, I'm looking to overclock so how would that play into this scenario?

This is my first time building a pc and here are my proto-specs. I'm trying to decide on the FX 4300 or 6300. Trying to keep it around $650. Feel free to de/reconstruct!

When your looking at the same chip architecture & comparing single thread performance it's largely determined on which has a higher clock speed. According to this - http://cpuboss.com/cpus/AMD-FX-6300-vs-AMD-FX-4300 - They're tied, this isn't the case however; I believe this is more accurate, http://www.cpu-world.com/Compare/295/AMD_FX-Series_FX-4300_vs_AMD_FX-Series_FX-6300.html This says the fx 4300 has 6% better single threaded performance. The fx 4300 has a 8.1% higher clock speed; in conclusion every chip is slightly different and higher clock speed doesn't result in exact percent gains, but you can except similar gains relevant to the overclocking percent.

If they're both same clock speed, they will perform exactly the same (Or...

If they're both same clock speed, they will perform exactly the same (Or so marginally different it's not worth mentioning). So, overclocking would make the 6300 a better chip over the 4300.

This gpu will give you much better performance, and will stay in your budget.

Not sure how long the $30 rebate will last, but it's worth picking up.

These are the benchmarks for these specific CPUs in gaming ( Back in 2012 when games were strictly single threaded , now more games are going multithreaded in which more cores will yield you more performance ).

It is clearly that the FX 6300 is stronger in single threaded apps despite the lower frequency , In short terms frequency means nothing when you compare two different CPUs nowadays.

Here's a another strong proof of the Strength on the 6300 in single threaded apps ( compared to other AMD competitors , Intel dominates this sector ) :

Cinebench:

In Multithreaded apps this is where the 6300 shines and really never fails to deliver :

Even for General usage the 6300 spanks the 4300

Conclusion : In real world terms frequency doesn't mean anything unless you're comparing two identical counterparts and for marginal price difference you get lots of horse power capable of even handling the strongest graphics cards when overclocked , unlimited potential and Multithreaded strength.

Get the 6300 and you won't regret it :)

Also dump that motherboard as it's known to burn and get the Gigabyte GA-970 UD3P which will handle overclocking like a champ thanks to its 8+2 power phase.

Ah I understand now. Thank you all for the help.

@rmark45matsu Ill go with the 6300 and up the Gpu to the R9 285!

@TopLuca Thanks for the heads up on the mobo, definitely going to switch!
