Solved Query i5 2500K or i5 3750K?

[ICIT2LOL]

Have just been asked which is best for new build (see title).

I am new building and getting stuff together and have my board - Asus P8Z77-V and was intending to get the Ivy Bridge but have seen a few Googles where the Sandy Bridge comes out a tad better than the Ivy Bridge.

So now I am wondering what to do / get??

 

[TVeblen]

I say Ivy Bridge.
2 Reasons: native USB 3.0 support and PCI-e 3.0.

So now I am wondering what to do / get??

Didn't you post recently that you originally built an i5-2500 and felt it was a mistake and that you should have gone with something stronger?

 

[ICIT2LOL]

Yes ignatzatsonic I did that was a build I did about a year ago now when the choice was a H67 or P67 board and as I was not intending to do any graphical stuff I thought I would get out of it cheaper. But now am kicking myself for going that way because I have been playing around a bit with graphics and want to try overclocking too.( In hindsight I wasn't thinking too bright eh?)

So I Googled SB v IB and it sort of seemed that the 2500K had the grunt and the 3750K had the graphics and not so much grunt. As I intend as does a friend who is doing a very similar build - to use a GTX 650 GPU I thought well get the CPU with the grunt as the card will take care of the graphics.

TV the current 2500 handles 3.0 USB and I am not sure what is meant by native support in the Ivy Bridge - is that better than what I have now?

I suppose the other thing that was swaying me at first towards the Ivy Bridge was the lower power consumption too.

USB 3.0 was integrated into the Sandy Bridge system boards by the manufacturers if they decided to do so. But this was an add-on system, much like a secondary SATA controller, and there were a lot of issues with performance in the system.

Ivy Bridge chipsets have USB 3.0 built in. So it is a part of the Intel system and should perform better. The only problem is the Intel chipset only allows for 2 ports.

3570K........it is an absolute beast. While SB can hit higher OC numbers ON AVERAGE, IB can reach damn near the same numbers and runs 10-15% more efficient. Basically 4.6GHz IB is equivalent to a SB clocked at 4.8GHz..........that is a basic generalization I've read on many hardware reviewer sites. The 3570K will be able to handle anything you throw at it without breaking a sweat, no question about that. Plus, you have the Z77 motherboard so you get the new technology upgrades that come with that. I know Z77 and Ivy Bridge CPU's utilize RAM more efficiently as well as USB 3.0 and PCI Express 3.0 which was mentioned earlier. Anybody that said that the 3570K doesn't have as much "grunt" as the 2500K is outside their mind. Go with the 3570K with the HD 4000 graphics, figure out how to use the 4000 graphics along with your discrete graphics card, and rock on. Should be a no-brainer since you already have the Z77 motherboard.

It sounds like a step backwards to have a Z77 board and put a Sandy Bridge chip in it, when you can get an Ivy Bridge.
From a gaming standpoint it might make sense, but in terms of having the new technology, go Ivy Bridge.

 

[kbrady1979]

With a Z77 mobo, there is no reason whatsoever to go with a 2500K, unless you have a friend that is willing to sell it to you on the cheap.......because he has upgraded to the 3570K. If you are straight up buying a new CPU and you aren't counting every penny, get the 3570K.

 

[ICIT2LOL]

Thanks everyone that explanation of the 3.0 was really what I needed to know so am going the 3570K

As it is my usual supplier has dropped the 2500K and also the 3570K price too from $245 to $233

I can honestly say from these few posts I have gained so much and again I cannot thank you folks enough

May have a look there if you don't already know it...Ivy Bridge Overclocking Guide

Choosed IB more for the HD Graphics & pci-e 3.0, than overclocking

 

[kbrady1979]

The 3570K can still be overclocked a bunch with decent cooling, just like Sandy Bridge. I have a guide to OC'ing Ivy Bridge/Z77 and it is really helpful. If you want me to send it to you, just pm me

Yeah KB I am getting the Deepcool Gamer Storm Assassin because this will be the last build I do for some time now and well may as well go the whole hog
Deepcool Gamer Storm Assassin CPU Cooler [CFAN-ASSASSIN] - $85.00 : PC Case Gear

 

[kbrady1979]

That looks nice! For that price range, I would look into a closed loop water cooling system. Easy to use, fabulous cooling and in a small package. I'm so glad I went with one for my build. Whisper quiet, and isn't a big unit hanging off the cpu socket. Also don't have to worry about it being close to the RAM slots. Either way the result is the same, a cool CPU. If the water cooling system interests you, I could point out some that work really good.

Very nice Air Cooler there. The rated full temps (58°) & noise (48dBA) are looking great on a pushed LGA 1155 Sandy Bridge 2500K...could be the same with Ivy or less temps.

I'll go Air cooling if you plan overclocking a little, with low profile 1600Mhz CL8 or above Ram memory.

PS: I found mounting Ram low profile are 38mm high on my Asus Mb and my Cpu cooler dual-fan and when mounted , is 42mm high and hide one slot of four.

This Deepcool gonna hide at least 3 slots....on your Asus z77

Ok KB fire away my supplier does a few and only Antecs Corsairs Intel (1 but it does state it suits the extremes -i7's) and Thermaltake brands. But if necessary I could go elsewhere.

Now I have had a look at some and the ones that I find are quite impressive - remembering I have never used liquid before areCorsair Hydro Series H70 Core CPU Cooler [CWCH70-CORE] - $89.00 : PC Case Gear

Intel RTS2011LC Liquid Cooling System [BXRTS2011LC] - $85.00 : PC Case Gear and the price is about what I would have paid for the Deepcool.

Thanks Non for that ref to the Asus boards - so much more info than the usual stuff
As for cooling well cannot make up my mind yet.

 

[NoN]

Those Liquid Cooling System are well reputed and look very nice in a windowed case, but i found heat-up more than Air cooling and are less reliable in time. I can understand you, if it gonna be a machine to keep for a long time.

Perhaps go Air cooling before and in a few years those liquid kit will be as efficient as air cooling.

 

[kbrady1979]

The Corsair is good, I think there is a Thermaltake Pro that has got good reviews, and the Intel I can personally tell you is good. Low temps, can handle a buttload of OC'ing and you can't hear it at all. The best closed looped cpu coolers have the thicker radiator. If you ever see a unit that has a thinner radiator(25mm) it is usually a value oriented one. The good water coolers have a radiator between 45-50 mm. The Intel one just comes with 1 fan and honestly, I don't know that I would see a difference in my temps if got 2 and had a push/pull setup. I have mine set up to pull colder air from outside the case and blow it across the cooling fins rather than blow hot air from the case across the cooling fins, and because of that, the fan has been turned around and the blue led doesn't light up the interior of the case.........something to keep in mind if you care about that.

Here is a pic of it installed..........


In reference to them getting hot.......if you mean the pump(the part on the cpu) mine is cool to the touch 99% of the time. After I read that, I was curious and had to check for myself lol. The only bad thing I've read about the higher quality kits are some are hard to install. The Intel was not hard, just takes some patience and a 2nd set of hands would not be a bad idea.

Unusual mounted liquid cooler but i suppose it could be a good alternate solution for extracting & cool.

Does the exterior mesh doesn't block that too much air?

That is how closed loop water cooling kits are suppose to be mounted...this way, or with the hoses at the bottom of the radiator....either way is fine.

What exterior mesh are you talking about? The case chassis?

Mine cools very well, while it's idling, it runs anywhere from 20-25*C and while using Aida64 to stress test it, it gets to about 50-52*C. That is with a 20% overclock!
