I3 2120 vs any i5

Alright, so obviously I'm trying to make a budget build that is made for gaming. I'm basically trying to find out exactly if any of the i5 cpu's are really that big of a boast up from the i3 2120 specifically without going way over on the price? I know they will be updating the intel cpu's very soon, but honestly I'm not that worried about that as long as I'm getting good playable frame rates.

I'm using a radeon HisQ 7850 2 gb graphics card right along side this cpu. So what would honestly be the best and will it be that big of a difference?

I also plan on doing no OCing on this rig.

The i5 will get you some better performance on games that can actually use the 4 cores (like BF3) but you would be well served with the i3

BF3 Multiplayer will see a big benefit from an i5 over the i3.

Other than that, the performance difference won't be very significant.

How big of a difference?? Thought I would ask seeing as I play a lot of BF3. Though sadly on Xbox 360 right now.

It's nothing major if you have a card backing it up like that HD7850.

You may see a difference of around ~10-20 FPS going with an i3 over the i5. You'll see an even bigger gap if you choose an unlocked i5.

Regardless, you'll still see a much smoother gaming experience than that Xbox of yours :sarcastic:  and an i3 will still yield a smooth gaming experience.

How easy is the turbo boost that comes on a i5 2400? It was recommended from another thread of mine that I just put up. Is that the same as overclocking it or is it somehow different?
August 29, 2012 1:29:14 AM

So overclocking it to 3.4 or .5 so on and so forth wouldn't be to difficult of a task?

You could overclock the i5 2400 to around 4Ghz if you increase the Turbo Multiplier. However, that's as far as you could take it.

So yes, it's a very small overclock.

If I'm not mistaken, no, it shouldn't be too difficult to achieve. You could easily reach 4Ghz on stock voltage.

But even without overclocking and the way games are going, especially if more games will use more cores like BF3, it would probably be a safer bet to get the i5 then yes? This is assuming more games will start using multiple cores with BF's success.

Yes even without overclocking, it would be safer to go with a Quad Core chip like an i5 for future gaming purposes.

It may also be worth mentioning that the additional cores from the i5 will also help in heavy stuff like video encoding and such. Depending on your line of work or hobbies it may be useful in the future
August 29, 2012 1:28:51 PM

the i5 also has turbo boost, which will OC the CPU automatically, should there be thermal headroom to do so.

I would personally recommend a i5 for future needs ultimately saving on needing a short term CPU upgrade because the dual core is no longer sufficient.

someone should tell my i3 2120 that :lol: 
August 29, 2012 3:59:30 PM

Alright then. You have an I3 2120. Do you play Battlefield and if so how well does it run?

If you read the entire sentence I mentioned short term, new gaming engines will put a strain on the dual core, a quad core i5 gives him more longivity.

I am so pleased your dual core suffices.
August 29, 2012 4:06:57 PM

I'm sure, from what I have been seeing with games like BF3. The next generation of games will probably will be using multiple core style games. I'm sure a I3 would be good for another year, but I already plan on buying a way to expensive Graphics Card next year and would like to wait 2 to 3 years on a new CPU.

Ideally for gaming you want to change graphics cards twice between changing CPU's, the graphics cards are the biggest players and newer tech makes the biggest difference in performance. Normally 3-4 years for CPU's and 18 months per Graphics card, unless you have the money to change out per generation.
August 29, 2012 4:20:19 PM

Difference between I5 2400 and I5 2500k? I'm just going to throw this out hear randomly, seeing as I'm not playing on upgrading my graphics card from what it is as I'm not going to have it for very long.

:ange: 
no i haven't play BF3 64 player maps with this rig; tried it, didn't appeal to me and i have other games.
(and be careful what you take for truth because i can "tell" you anything while sitting behind my keyboard)

because this topic comes up from time to time; after extensive researching for several months looking through forums without the benefit of a reputable site doing benchmarks; the most consistent for playable frame rates in MP maps was an i3 rig with an equally match graphics card such as a 6870 or 560ti. having a larger grfx card such as a 7870 or 570 will get choked by the i3 due to the load of the game.

and your choice for B.A. pretty much pointed that out. you can ignore me if you wish, i'll have to admit i enjoy poking quadcore fanboys. as much as they hate to be reminded, an i3 outperforms many quads except for a few C2Q and PIIx4s aside from sandy i5s.

Nothing at stock but the 2500k has unlocked multipliers for overclocking, but that in turn requires a good motherboard and that in turn costs money.

Budget: 2400+decent H61+Good Graphics card/Sound Card+8GB RAM DDR3 1333/1600

High End (affordability) i5 3570K + Z77 (Gigabyte Z77 UD5H feature rich and overclocks like a beast for rather low cost) + Good Graphics + 8GB RAM 1866 or better + SSD

and i am going to poke you again. an H61 is a horrible recommendation to make. no usb3 or SATAIII. the B75 chipset is so much better for about the same price.
August 29, 2012 4:32:34 PM

Alright Looniam. What about a 7850 right along side a I3 2120 for playing BF3 on not 64 player maps? Or just general benchmarks for most of your games. I see you use a 550 so I'm just wonder your knowledge of these things seeing as you own a 2120
a b à CPUs
August 29, 2012 4:33:54 PM

There is that too though I would prefer putting a 3450 on that then to get the benefits of a IB chip. There is one MSI H61 with USB 3.0 but it seems to be discontinued.

As for the DC/QC I still rock my old 771 C2 Extreme and it can still game, I was merely going on shelf life where the QC have a more viable future, particularly as the OP wants to get 3-4 years out of it.
August 29, 2012 4:34:04 PM

I got a asrock z68 pro3 gen3 sitting in my cart. I do not plan on using multiple cards anytime in the near future. Just so you guys know.

What budget are you going on and what do you need to get in that budget. As in the other thread the HD 7850 is a good card, no longer the best p/p in the range but it will more than happily play BF3 at 50ish FPS maxed presets at 1920x1080P
August 29, 2012 4:39:56 PM

Somewhere around 700$ though i have a thread of my first build if u want to go see. 700 doesnt mean 799. lol

I will have a look when I get home. TH does a regular build off for $700 on components you can still get a solid setup.

for BF3 it really does not matter for single person campaign mode:

strictly depends on your GPU.
for something like skyrim it will compare to anything short of an i5:

now metro 2033 i swear is the most brutal game used in benchmarking (and i think reflects the performance of cpus in intensive gaming)


as far as any benchmarking i have done is BFBC2:
Undervolting i3 2120 (the only "fun" there is)



the hyperthreading of an i3, which is less than the performance of a true quad core, does help however:

look at CPU 2 and 4 to see the load.

EDIT: right now i am looking around for a cheaper gtx570 or great 560ti448 and see what more of a load in can get on this i3 - the 550ti in no way puts a load on it in any games.

Metro 2033 will break you :p  That game is terrible to everything 3930K with Two 3GB 580's maxed out at extreme res didn't hit double figures with all maxed settings.......the game is a killer.
August 29, 2012 7:00:31 PM

Thats with putting a lot of the weight onto the cpu right? Also I still need my question answered if the i3 will bottleneck with the 7850, though I think I'm going to stick with the I5

I don't believe it will. Metro is a tessellation monster that kills CPU and GPU alike.

No, I highly doubt it will. The i3 is still a very modest CPU and depending on the title you play, you'll see little to no bottlenecking.

However, if you can squeeze in an i5 into your rig, I will definitely recommend going that route. As modest as the i3 is, nothing can beat a SB Quad :)

the direct answer is no.
i neglected to inform you that the first benchmarks i posted were with a 7970 and as you can see depending on the game there was little if any performance difference. there is a regular poster around here (geofelt) that has an i3 and 7870 and claims to not have any gaming problems.
