Question on which CPU to buy? (3570k or 2500k)

[Ninnetyer]

For highest overclock buy yourself a tuniq tower 120 or 120 extreme, 10 to 15c better temps than a Hyper 212/412 and its only $20 dollars more. Just make sure you buy standard height ram not the ones with big heatsinks or it won't fit.

Yeah I don't think could find those models around here..
The better stuff I found was this a Corsair H80 wont buy those until 3 months or more.

So finally after thinking like a complete night, I got this;

SB Pros:
* It is Good for Overclocking, (good temperatures)
* Not bad compared to IB
* People have more experience with it (which they can help you overclock its faster and easily).
SB Cons:
* More consumption compared to IB
* Old technology compared to IB
* Worst IGP if you want to use it, or use in Virtu MVP (not sure about this yet), compared to IB
* There is no PCI 3.0 (useful for New high end Video Cards and Oced ones).
* No native support for Memory 1600 mhz Ram (yea it doesn't matter that much, but still)

IB Pros:
* Less consumption.
* PCI 3.0 support
* Better IGP, may increase a little performances for games (not sure about this yet)
* Native support for 1600 Mhz ram
IB Cons:
* Bad for overclock produces more heat (unless you change the thermal paste inside the "cake", so It can transfer more heat to dissipation)
* Difficult overclocking, not mature enough yet

Hope all of this is correct, and so I have to decide stick with the Ivy Bridge, sadly Intel make a bad move doing that with the thermal paste, but still if you are on a budget like me it is going to be hard decide for one or the other, and because I'm only thinking overclocking it to 4.2, don't think I could risk more or over-voltage it, My plans are to try to overclock it with default voltage.

Appreciate all the answers, you guys make me search for info as hell with answers I didn't understand, so I learned a little more of all this stuff.

Ill be around when I got that CPU searching for Info to overclock it with default volt, I hope my 412 is enough for this task. Please let me know if I should know something related to this topic.

So thank you again guys and moderator can close this, or I don't know how it will work, I come from forums where if you find your answer it must be closed.

Cheers.:thumbsup:

I didn't find overclocking my 3570k all that hard. Granted I'm running a Noctua NH-D14.

IB does NOT produce more heat. It runs hotter, that's not the same thing.

Ivy has a sweet spot of around 4.3-4.4 after that you need a hell of a voltage increase and it pulls crazy watts after 4.8 ghz

Go look it up,its how the tri gate transistors were tuned for.

Iv seen ivys on here needing 1.420 volts for 4.6 ghz when sandys have hit 5 ghz at that voltage and pull about the same watts when over locked past 4.7

The best bang for the buck would be a used 2600k

8 threads and a safe 4.7-8 overclock

I have looked it up. Everything I've seen shows IB using less voltage than SB at the same clock speeds and every single review I've read shows it using less power. You may be able to find an odd example here and there where your example may hold true, but by in large IB is more efficient even when overclocked. You're taking the best case scenario for SB and worst case for IB. Case in point, why aren't you running at 5GHz if you only needed another .005v to do it?

I don't know what you looked at but after the sweet spot of about 4.4ghz trigate pulls more watts and needs more volts.

Here is a review of a 2600k and a 3770k both at 4.9ghz and the ivy is consuming more watts and needs more volts and runs 20c hotter.

When I benched an ivy at 5.2ghz it was pulling over 300 watts and throttled within 2 seconds of testing

Ivy has higher IPC by what, 8% or so? A 4.4 Ivy is about as fast as a 4.75 Sandy, then.

 

[2is]

Guess you can run it at 4.7 instead of 4.9 and still have better performance and lower consumption than SB at higher clocks, which it isn't guaranteed to reach. Like I said, if it were that easy, I have no doubt you'd be at 5GHz. You didn't hit 4.8GHz and say "awesome, that's exactly what I wanted" you wanted 5GHz and weren't able to hit it reliably (or perhaps at all) with anything resembling decent temps or voltage levels. IB > SB

 

[grkM3]

My chip is actually at 5.2-5.4 ghz and I haven't updated my sig in months.

I was challenged by a user with an overclocked ivy and he could not beat my benches and I think from memory I hit 10.34 in cinbench with my 2600k with just water cooling.I'd love to see your ivy break do that without throttling

May I ask what it is you do with your CPU other than benching? What non-benching programs do you use?

 

[tigersty1e]

Yup, good for you mate. Pci-E 3 does nothing. A 4.9-5.2ghz Sandy (which your 3570 will not do unless you replace the paste) has been beating your Highly overclocked Ivy CPU for 1.5 years now, and costs less cashola.

Who cares about 30 watts when PSU's put out over 1000? Ivy K's are horrible buys compared to Sandy, but are great compared to Faildozer.

anybody with a cooling solution to bring sandy up to 4.9-5.2 will take an ivy to 4.6-4.8.

with prices almost the same, you'd have to be stupid to buy a sandy bridge system today.

 

[2is]

I'm on air, not water so it wont' do 5GHz without throttling, but doesn't need to since it's faster per clock anyway. So are you at 4.8? 5.0? 5.2? or 5.4? And i'm talking about your 247 speed, not something you hit for a few minutes for a purpose of beating someone in a benchmark.

This past few days its been encoding about 500gb of HD content.just finished encoding 8 blue ray movies for my media server.

I got lucky with my 2600k as it did 5ghz with stock cooler but now since its been abused to death and has seen over 1.7 volts it needs more power to hit high clocks.

If you have a 400 dollar mb you always try different setting and this chip will do5ghz all week if I wanted it 24/7 but depending what I'm using the computer for I'll clock it higher if need be.

I like how the sandy haters can't take that almost any sandy will do 5ghz if you jam 1.5 volts into and at 5ghz it will out perform most ivys.

My chip with even 1.575 volts would not throttle and it scaled up to 1.7 going for record runs but hey have a blast with an ivy that will never break 5 ghz 24/7

 

[2is]

It's more like ivy haters. Read the thread again and see which side started the back and forth. Most sandys aren't doing 5ghz and that's a fact. Not everyone wants to degrade their chip. I'd hardly be bragging about a suicide 5+ ghz run much less claiming that's a typical overclock and pretending it's safe until questioned about it.

Seem unnecessary to degrade your chip over something like that. I usually run stuff like that overnight.

 

[Tempered81]

Do you really think there would be threads like this everywhere if it weren't so?

Who wants to run 1.5v on their CPU and degrade it? Seriously...

Big deal you ran a benchmark at 1.7v. Why don't you go over to xtremesystems.org and hop in the benchmark forum so you can compare your e-peen hyper pi scores. I seriously cannot believe people think it's cool to spend $200+ on a CPU and push ridiculous voltages through it and have it barely boot to windows and run super pi then grab a screenshot before they have to shut it down.

My CPU will last 4x longer at 4.6 and cruise along with PCIe 3.0. You might someday say "Hey why is my GPU running slower than reviews?" and the answer will be PCIe 2.0 is too slow for Big Kepler. Who knows.

Besides all that, if you're willing to do 1.5v+ 24/7 or even 1.7v then you're willing to de-lid your Ivy CPU and then your whole argument is moot. You'll hit Sandy clocks no issue.


To the OP. I thought about this myself. Ivy vs Sandy and I went Ivy because the price was very minimal difference (there were no killer deals on 2500k cpus) and I wanted the future usage of PCIe 3.0. Yeah maybe now that doesn't make much difference, but as long as I may keep this system...it might someday and for my money I plan for the idea that maybe it'll be good to have.

Acchhemm....em.. em .em em.

If your 4x longer duration is 12 years vs 3 years, it's a m00t point because Most of us overclockers will have moved on to different platform and chips within 3 years.

The PCIe.3.0 thing is not going to matter for at least 2 years. which is why sandy vs ivy is still a debate.

since for almost all p67 and z68 boards, ivy will be a drop in cpu and will support 3.0,, ivy has absolutely NO worthwhile advantages if it's price is close to or higher than sandy.

Lower power usage, faster per clock...

Besides, if you burn out your CPU in 3 years then you have zero resale when you decide to upgrade. It all matters.

mm...

Lower power usage is not a factor, because we can now overclock with speedstep ON,

since most of the time, the CPU stays at idle 1.0v or less, you will likely gain very little in terms of total power saved over-time.

Ivy is faster per clock, but the advantage is "between" 0-15% in benchmarks. So let's say it's on average 7% better than Sandybridge, If it's cost is even 10% greater, it's not a good buy.

To add to that, the overclocking disadvantages of Ivy has been clearly established.

The 22nm tech is also NOT time tested, we're not absolutely sure how it'll hold up to overclocking vs the WELL tested sandybridge.


Sandy is still the better buy if it is "at all" and most often is cheaper than IVY.


This is the case in the USA at least. If you live in another country, and the prices are the same, then IVY makes sense, but just barely, due to the disadvantages I've mentioned.

 

[2is]

Not time tested isnt a disadvantage. It's a fear. A baseless one IMO

 

[blastingcap]

Sandy's "more" time-tested but still hasn't been out in the field for that long, either, relative to, say, Wolfdale.
