FX-8120 VS I5-2500

Tags:
Last response: in CPUs
Share

Ok Im having issues ( Still ) About deciding which way to go with my upgrade.

I've been doing alot of passmark comparing and it SEEMS the FX-8120 can keep up with the I5 2500 in most situations. My concern now is the issues the bulldozer platform has had within windows 7 and what sort of hell I would have to endure to get it working. I like the prospect of the Amd FX build because I can build it for about 50$ less than an I5 build with decent parts. (Seems like the LGA 1155 Mobos are a touch more expensive base priced than the AM3+ mobos in general.)

So I suppose the question is this... If I do get the FX chipset (With a UEFI ready Mobo) what sort of other problems will I face?

I would like to get my order finished tonite and Im really hoping to put this whole idea to rest. I just want the best upgrade I can get for a reasonable amount of money. Ill post my current specs here too if it helps:

Phenom II x4 940 BE
4GB DDR2 800 ram
EVGA GTX-260
Biostar TA790g A2+ Mobo (I Think)

I plan on keeping my card as it is, for now I feel like upgrading from DDR2 to DDR3 will help enough for me to rock out skyrim for the time being...there really arent any games on the way that I even want to play that my 260 couldn't handle.

Thanks all!

Is there technical reasoning behind that? Im looking for a conclusive reason not fanboyism =P

And the difference between the 2500 and the 2500k isnt worth the price jump. We are talking what, 400 or so more marks between the two? Ill get the 2500 if I get intel.

Haha me intel fanboy? i have the bulldozer. ok let me give you a reason the bulldozer acctually isnt a 8 core its more like 4 real cores with advanced hypertrheading second of all its single core performance is far behind the core i5 2500k also the 2500k uses less power and overclocks better and the 2500k

here linus explains the archteuire of bulldozer a bit http://www.youtube.com/watch?v=PwTXoswO0bI

and here he compares the 2500k with 8120 http://www.youtube.com/watch?v=1kd4dvLJQP4 the i5 2500k wins in every game

Also the difrence between the 2500 and the 2500k is you cant really overclock the 2500 the k at the end means the multiplyer is unlocked allowing easy overclocking so if your gonna overclock the the 2500k if not the 2500
the only real reason to get the bulldozer is if your using photoshop (like me) so yea that enough info?

Are you looking at passmark? Don't believe in that bs. Get the 2500k because you can overclock it and keep up with the competition in case you do not upgrade to ivybridge.

Those answers are tons more helpful...However I will probably never overclock. I only had to burn out one chip to never want to touch it again. And as much as these suckers are starting to cost now days....ish...

I dont care about the competition so much I just care about a successful and worthwhile upgrade from what I currently have.

Gaming, music, I do some audio engineering, 3d modeling, Working on getting into modding skyrim. Gaming is sorta light right now. I have BF3 but even my current system can run it with minimal issues. (though Im hoping I would see some improvements with the upgrade) Otherwise I play skyrim.

Oh... well that makes things different the core i5 is a quad core with NO hyperthreading and if your doing 3d modeling etc i would say IF your doing tasks like that alot you could get

I am i getting one of these toos ( i like to buy lots of computer parts for the hell of it) i currently have a core i7 740qm and core i3 2100 amd 8120 im gonna go for one

Actually Linus showed that in gaming the i5 2500K was pretty much a dead heat with the BD 8150

Yeah Im looking at this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Rating wise this board seems to keep with with same price range msi and asus boards, and frankly it seems the reviews are actually better. Never used ASrock and I swore I never would...Then again I swore Id never go back to intel so why not give it a whirl.

Real fast too, how is the stock I5 cooler? I have a cooler but I think its AMD only and a cooler isnt in my current budget. Im hoping they are well made, or at least I can get speed fan working on the stock and keep it running at 100%.

If you arent overclocking, the normal is to get the i5-2400 because the extra money for just .1GHz isnt worth it. Also if you have a microcenter near you I think you can get the i5-2500k for $180. Just something to throw out there...

I added on the motherboard that I did so I can overclock. Idk Im indecisive about it, but I suppose if I do want to some day Id rather have what I need. But honestly, a stock 2500 vs a stock 2500k, is there really a difference? It would save me a good chuck of change there...

don't ever look at passmark, its such a worthless benchmark.

Anyways, the i5 is your best bet. should be no problem to get one and a mobo for less than $400.

Whats your current cpu if you can play bf3?
CPUs Expert

Why would you hand build a computer and not be alright with overclocking. Get the k version so you can overclock for skyrim. You will gain fps all the way to 4.0 ghz in that game and if your even remotely careful you can't hurt these chips.

I hand build because I refuse to supply these media giants MORE money for the products that tend to fail...(foxconn in my Pre boxed pc? No thank you.) I like knowing what Im getting and that IM the one putting it together. Guess its peace of mind?

My specs are already at the top of the page but my current cpu is a phenom II 940 BE (DDR2)

The bulldozer seems like an interesting CPU to recommend to my mom who doesn't game and only works with excel, word, outlook, internet. 8 cores would sure make it last a long time even if its not as fast as a i7-920 or i5-2500. They said that about quadcores when they came out, "Whos going to ever use 4 cores?" I bought a q6600 right as it came out and that thing lasted me till last year so about 4 years. I figure the same is true with bulldozer since the more cores the more computers 3-4 years from now will use.

Granted in my main setup i would never use AMD for gaming since they are all but a joke of serious gamers these days for making crappy gaming cpus since after the pentium 4 days. For those that say intel is overpriced for what you get, WTF are you guys smoking??? A i5-2500k as stated is only 180$ and a BD 8 core is 250$, the i5-2500k easily outlaps the bulldozer in every test including multi core tests.

your mom would probably never notice the difference between the 8 cores and a celeron, the software like that that she uses never require more processing power. My c2d computer used as a htpc still does all that easily and its 7 years old, I never notice slowness unless I have a game running or something.

Well the 8150 is a great gamer CPU and great all around CPU actually and I am pleased as a gamer with it so anyway here is a link I found good info and 8150 actually beat 2500K overall in gaming http://www.youtube.com/watch?v=1kd4dvLJQP4

Well i went BD and i am happy with it.


your happy with mediocre performance and lower fps in some game(skyrim, bf3, etc... name games)

on this link you can look at the first graph but the interesting one is when you go from maxing everything out(less cpu stress) to a more reasonable low af and no aa the i7 dominates the i5 and everything else.

its not a 8 core cpu btw... its a 4 core(module) with amd's version of hyperthreading( a shitty one at that). A 8150 will never be as good as a current i7 EVER lol. idk if you were getting at that but in 4 years the i7 2600k will still be better and i wouldnt be surprised if the 2500k was too.

i would agree. he choose to run all gpu bound games which is not a good indicator of cpu power. metro 2033 as a cpu benchmark??????? and probably bfbc2 single player.

its a well know fact that the i7 2600k is better then the 8150 so why would it be worse then the 8150 in 4 years...

thats not your entire post.

Better cpu is also subjective. The FX 8150 still beats the i7 in things and you can never predict where things will go 100% of the time so you are again stating an opinion.

what exactly is bulldozers architectue then. you cant say its 8 cores because there are not 8 complete cores... so what is it then.

http://www.anandtech.com/bench/Product/434?vs=287
7-zip is the only win for bulldozer....
AND we are talking about gaming here. Show me a benchmark showing that the 8150 is undeniably better then the i7.

edit:
3 year old intels are still faster or about the same now then 3 year old amd's just like they were three years ago and intel has an even larger lead now.

you don't have anything to call it hyperthreading. Its completely different. As I said, please don't talk about things you know nothing about.

Please show me where I said it is hyperthreading. If you can read you would see i compared it to intel hyperthreading as amds version of hyper threading.

But its easy and immature to tell me not to do something like you are doing right now acting like you know everything about it. Hell yeah there is some differences but it boils down to the same concept.

Please explain why i know nothing and explain why i am wrong. Keep in mind i never called it the same as Intels hypertheading.

Looks like BD fx - 8150 and i5 2500k are pretty similar in terms of gaming performance add in the additional average cost of an Intel platform and slightly higher cost of the 8150 chip and looks like AMD and Intel offer up pretty even results on average as far as gaming as I have outlined and double certified above with link provided.

^ Exactly why i stated a 0.1 fps if you can even call it that increase lol

and I never did all I stated was BD FX-8150 offered up a similar performance as i5 2500K and then I when on to prove it double certified to boot.
