Building for gaming 2500k or 3570k Ivy

[d3fu5i0n]

Remember that just because Ivy gets hotter, doesn't mean it produces more heat. Ivy is more efficient than Sandy under normal voltages and just gets hotter because the dies are smaller and can't dissipate the heat quickly enough. A match can be extremely hot, but a campfire produces more heat.

Indeed

I wouldn't upgrade to IVB if I'm already on SAB, but the OP is on 775; much like I was [Q6700]. I'd still say go for the newest chipset and CPU - he can always use a SAB CPU with a Z77, if he wants to.
The increase you see from 775 to 1155 in performance and the drop in power consumption is phenomenal.

Ivy does not dissipate the heat as well because intel is using a different thermal compound between the cpu die and the metal shield you put the heatsink on.

No easy way to fix it. As a result ivy will run hotter than it should.

Somebody will have to remove the cover and replace intels new paste then test to see how much better the thermal transfer is.

Wait someone has done this. It looks like once intels paste has been replaced on ivy the non OC load temps drop 11c and 4.6Ghz OC drop 20c. Big difference.

Another way of looking at intels IVY decision in a better light.

Direct contact with the core is the best. Right now its much easier to get to the core since they used paste vs soldering the HSF to the core. But you run the risk of cracking the corner off the core if you do not seat the water block properly.

Hard core overclockers should be happy intel used thermal paste, it will make it much easier to access the core.

As I said...likely a NH-D14 will go on it. Not low end. Just really looking for 24/7 reliability. 4.2Ghz is a very respectable speed I think.

Ivy.

 

[ShintaiDK]

The question is rather if you want your IB over 4.5Ghz. That equals to 4.7Ghz SB.

I would pick IB.

 

[AtenRa]

I dont see any reason why anyone would choose SB over IB for a new system build. Only if you put socket 2011 in to the equation for 6-core SB.

I chose sb over ib.

In favor of SB + z68:

Price to Performance ratio, SB 2500k combo $350 buy-able ONLINE

_______________________IB at $350 only at Microcenter, otherwise at least $430-450

IB is not 20% faster. :\

Easy Overclocking, no delid, you can't get IB to 4.5 without that dreaded 100C over your head. Full load doesn't happen often, but it's still a gloomy cloud

Finally SB is Time tested, almost bug free

 

[rgallant]

yes great deal on a web beater sb +z68
-but next year I\we could rock gtx780's sli + raid card +water block's so 1500 ish ,

-so I might spring for the extra $10.00 for ib today so I won't have the throw the sb\z68 in the garbage to run $1500.00 dollars of parts @ full speed next year.

Everything he said..................but in my voice.

Im talking about CPU to CPU comparison because not everyone can get a combo deal.

the asus z68 supports ivy, AND has pcie 3.0

Everyone can get the $350 SB combo I got.. It was last week.. I'm sure it'll come up again soon. mine was from NCIX Online site.

i5 2500k + asus z68 pro g3 for $350 after $20MIR.

 

[blastingcap]

At equal price or near-equal CPU+mobo price, I'd go Ivy, especially with low or no OCing.

If you can get an equivalent SB CPU+mobo combo for more than $20 less, that would be tempting if you OC, else it's still not good enough. Ivy uses less power and has higher IPC.

Also if you think you'll keep your combo around for a long time and go SLI/CF you may value PCIe 3.0 more. Less than very high end (far future high end?) SLI/CF and you will realistically not saturate the PCIe 2.0 bus anyway.

ur just trying to make urself feel better for having already jumped trains.

What, like I didn't perform this analysis prior to buying? Not sure if you're being serious or not. If you're serious... troll harder. I mean, you could easily say that the pro-SB people are trying to make themselves feel better for buying older, less efficient tech.

There seems to be a lot of confusion with "heat" and "power". Some people seem to think because ivy has warmer temps, it uses more power and produces more heat. This is not the case.

IB runs hotter but produces less heat. It's like the difference between a flame from a lighter and a heating vent. The flame is way hotter than the vent, but turn both on for 10 minutes and the vent will heat up a room far more than the small flame from the lighter.

IB also uses less power as shown by every sinlge review I've read thus far.

 

[philipma1957]

Seems to me the ivb vs snb debate can't be settled until people have oc'ed their ivb at 4.2 and up for close to a year. The chip is smaller and no one knows how well they will stand up to a year of over clocking.

The sandy bridge chips have a good track record at the 1 year mark they are not falling over from heat exhaustion so to speak. I went sandy bridge on all the build I did this year. IVB is not leaps and bounds ahead of sandy bridge.

If an i5 3570k clocked 4.2 on air and used less power with lower temps or equal temps for a year without dying It would be better then sandybridge right now how can anyone really tell.

I would think Intel knows that answer and has done a few long 24/7 tests with ivb es chips , but I don't see results.

I don't recall any CPU in Intel's history that had an issue with "heat fatigue" after 1 year. We can start pulling "what if" scenarios out of our asses all day but it really isn't necessary to make an informed decision. Obviously there are exceptions for extreme overclocking overvolting, but that isn't what we are talking about here.

D14 has no problems with Ivy. My 3770k @ 4.5 only gets to mid-60s under load in realtemp.

 

[moriz]

The 3570k that I'm using had no problems hitting 4.5GHz. Temps top out at 70C with a voltage offset of +0.077V and a mugen-3 cooler. So out of the two, go with ivy bridge.

 

[Rvenger]

My 3770k is spiking hard on core 2 even at stock speeds. I'm seeing mid 60s and low 70s at times. I am having all kinds of bad luck with my current build. Makes me think that I should have left my SB system alone.

 

[2is]

Are you actually having problems or just temp spikes? Core 2 appears to be the hottest running one for nearly everybody.

 

[Rvenger]

Temps just seem to be a little crazy on this CPU and I understand I have a launch week 4 IVB. I might have to go water cooling if I even plan on overclocking this chip.


EDIT: I just wanted to make note that my core 2 runs about 12c hotter than all the other cores. Crazy huh?

 

[blastingcap]

If you makes you feel any better, my Core 1 is over 10C hotter than my coldest core, at load. Even at idle it's still several degrees C hotter. I've remounted and reapplied TIM and have never seen more than 1C difference no matter what. I'm assuming the problem lies beneath the heatspreader, not above it.

Not the same as any other intel cpu change.


the die's transistor shrink is the biggest ever percentage wise in one swap. 32nm to 22nm
