3570k vs FX 8150  

post #1 of 20
Thread Starter 
@ microcenter there is only a $10 difference in price.

What is the performance difference? Is it even noticeable? Do both accept pci express 3.0(even though i read 2.1-3.0 is not much difference)? I read somewhere that AMD cant use high speed ram?

I pretty much only play video games and want to play Battlefield 3. This will be for a new build and only play games on my netbook and phone at the moment.

Thanks.

They will be about equal in performance when ALL threads are used, i5 will crush it in single to 4 threaded apps, absolutely. It's very noticeable in everything that isn't heavily threaded. FX series can use high speed ram, I've seen up to 2400mhz.


i5 3570k will use less power, and be stronger in all apps that use less then 8 threads, it will also get a higher overclock (if you do that sort of thing) with equal cooling.

The performance difference in pci 2 to 3 is negligible with current gen cards. I don't believe Bulldozer has pci e 3.0 support.

That 3570k will destroy the fx in basically everything that matters. Since you are only gaming there is no reason to get the 8150.

Gaming is where the difference is most noticeable. So yes. Also, the FX8000 are no faster than the FX4000 in gaming.

For gaming you do not want the FX series, it's all playable, but the 3570k will offer higher minimum and average frame rates. As for the am3+ vs z77 if you did go with a Fx-81xx you'd want a quality board with good vrm setup because that thing is one of the most power hungry amd processors to date.

erunion thanks for the stats.

hmmm its a bit odd that skyrim fps differs much more between cpus... im guessing its a multi threaded game compared to Batman.

If I only saw the batman stats i would be fine with an fx processor 90fps its great for any game.

thanks guys

They should use the same number of threads. Skyrim is a more cpu intensive game.

For gaming the 3750k will perform better than a 8150. Anything else like video editing etc. the 8150 will help with that.
