Hey guys, wich one is better in gaming?
Athlon II x4 750k or Pentium G3420. The gpu that is being used is Sapphire radeon hd 7850 1GB. Resolution: 1440x900
I know that the athlon has 4 cores but they are weak cores. The pentium has only 2 cores but they are great and the pentium has much better upgradability options than the athlon. The athlon costs €66 and the pentium only costs €56.
Thanks for helping me out
 
Solution
The G3420 will NOT bottleneck on a hd7850 at 900p or 1080p. It also has better core for core performance and much better thread for thread performance. Plus the 1150 intel socket has much more upgradability. Benchmarks done with a G3420 and i7 3770 with gtx670 1080p. It kept up with the i7 3770 in gaming and the gtx670 fell short before the G3420 bottlenecked. The 760k is better than the 750k but niether are quad core. They are 2 modules with 2 threads per module giving you 4 mediocre threads. The only way I would recommend the more expensive 760k is if your gonig to oc it to at least 4.2ghz even then its not really worth it cause FM2+ really isn't looking to promising in the future. With directx12 coming and low level abilities less...
The Athlon II X4 750K is better because minimum 4 cores are what you need for gaming because games nowadays use more than 4 cores and which is why you should get the Athlon.

The Pentium with 2 cores would just not cut it now as far as gaming goes. So, better get the Athlon II 750k. It is a very good choice for the budget. Definitely get it.

The Athlon II is not a weaker core than the G3420, with both of them you are going to bottleneck a bit but the Athlon is a much safer bet if you get an AM3+ motherboard ( it has backwards compatibility with AM2, AM2+, and AM3 CPUs) because the next 2 generations of AMD FX processors will be on that socket.

4300 is €90 and they don't sell the phenom anymore :(
So wich one would you prefer? The pentium is €56 and the athlon is €66.
 

If there was a gun to my head, I'd take the Athlon because 2-core CPUs aren't enough anymore for gaming.

For what it is worth, I had a Pentium G860 (SB, 3.0 GHZ) and Radeon 7850 1GB and did not have problems playing any of the games that I wanted to play. I played BF3 Multiplayer with solid frame rates and low latency; I cannot remember the exact resolution but I know it was higher than 1440 x 900. Almost all of the games I played were stable at 1920 x 1080 with varying degrees of detail. YMMV. The Pentium G3420 is Ivy Bridge and 3.2 ghz, so it is even faster than my G860. As most games are GPU intensive, I would be surprised if you had issues with any games at 1440 x 900.

However, dual-cores will only become more obsolete as games continue to become more optimized for multicore.

Another consideration is whether or not you can overclock the AMD CPU. I'm pretty sure you cannot overclock with the Pentiums, but have no idea about the AMD. If you can overclock the AMD, that would be a huge plus in my book.

Best of luck with your decision.

For AMD there is one FM2 Athlon CPU available that you can overclock, there may be more as well I can't think of any off the top of my head. Most AMD processors are unlocked and ready to be overclocked, the Black Edition CPUs and the entire FX Series are overclockable.

Yes the athlon is overclockable. Btw, I'm going to be using a cx430m psu, should I get a cx500m? Maybe my friend will overclock later after some research because I have no idea how to overclock. We will possibly overclock the gpu aswell. Would a cx500 be enough?
Pentium g3420 is haswell btw, just letting you know :)

Oh, well that would be even faster yet! Like I said, at 1440 x 900, I don't think you can really go wrong with either CPU performance wise.

I would assume that the CX430 would be enough to sustain either system. There are plenty of good reviews for it online. The Antec VP450 is what I use and another highly rated PSU.

Two decent tools to figure out what PSU you need now (and for the future):

eXtreme PSU Calc:

NewEgg PSU Calc:

Best of luck with your decision!

Those two tools are essential for any PC build, no matter what you can never be sure how much wattage you need but these guys get it pretty close. Newegg's is much more basic but gives you simple results whereas the eXtreme one is better for if you already know all the details of your build and know all the fields it asks for. Either one you choose make sure that you calculate it once with your current setup and one more time with any expansion or upgrades you might put in to get an idea where you stand now and if you will need to upgrade your PSU in the future as well

False, 750k is a trinity chip and a 760k is a newer, better performing revision Richland chip. So it it is worth the extra cost which is tiny amount to begin with.

Is there a TDP change as well?

No, they have the same TDP rating of 100w.

With directx12 coming and low level abilities less load will put on the cpu and more on the gpu. Anyway the G3420 and a decent Z87 mobo is the better overall option. Not an intel fanboy. I currently run a fx6300@4.8ghz 1.45v and a Powercolor 270x DEVIL@1250/5900 1.206v.
