Ivy fail

[Krono5]

..but all the IB reviews I've read today are overclocking using air. Surely there's more headroom with a watercooled system. Your 2500K for example, is watercooled but the reports i've read the 3750 can hit 5GHz on air.

Yes, but not as much headroom for anything less than a very decent WC setup. The problem with IB is that it will reach a point where the temps go from 70c full load to 95c full load with only a very small increase of volts and any cooling you have needs to be able to dissepate this very quickly. No oners got a 3570k on 5Ghz on air, if they have they will of killed the chip as temps would be around the tjmax or throttling.

I've seen 4.9Ghz on a rasa WC kit iirc but even then temps were much higher than you'd want for 24/7 use. The difference between reasonably cheap WC and high end air is about 10c on SB, it's about the same on IB but the huge jump up in temps with only 0.1v or less will eat this up instantly so you're looking at multiple rads to get 5Ghz for a 24/7 clock.

This is what you'll need for IB to surpass SB as you may hit 5Ghz with lower end WC but the Sb will still do more upto a certain point.

Did you actually read my post we came to the same poiny, i jusy listed it at the top of my post

You reccomended Ib for anyone moving from older chipsets, whereas SB may be slightly better when OC'd above 4.8, then there's price to think of.

Ivy isn't a fail, but it's also not a logical choice over a 2500k when you're overclocking for most people.

I agree I wouldn't call it a fail, it just isn't worth the upgrade for higher end IB users.

I did this as most people will not be pushing Intel Ivybridge anywhere neat 5Ghz for a 24/7 overclock and I don't think price wise it will be much more then the current sandy line up. So based on this why not jump to Ivybridge and all the goodies that the chipset brings

Plus Intel are or have stopped production of sandybridge cpu's so they will become harder and harder to get hold of

Not yet, they are still to phase out i7 9xx until june and many other processors, so SB's will be available for quite a while yet.

 

[rotahn]

i think they mentioned in the IB launch webcast they are phasing out production from Q3 on the SB's

 

[Colonel_basic]

I have a i5 750 not overclocked as im using the standard cooler, is it worth going to ivy for gaming?

Is it not a well known fact most 2500k user's settle for 4.5Ghz for a 24/7 over clock?

I would settle for a 4.5Ghz on 3570k IB, it should chew up BF3 for quite a while?

Spending hundreds on watercooling for a couple hundred MHz is out of the question for most people. It's terrible value for money.

4.5Ghz would be a nice overclock by anyone's standards and will chew up bf3 quite well even more so people taking advanage of the MVP engine that works with the Ivybridge CPU

Can't even remember the original core series, but I know that 45 nm westmeres clocked better than conroes, and 32 nm gulftown and SB both clocked better than 45 nm I7s.

No point comparing Westmere/Nehalem to Conroe- they're both completely different architectures. The 65nm Conroe/Kentsfield was able to clock higher than the 45nm Wolfdale/Yorkfield since it could take higher voltages, but both are the same architectures. Hence why the Q6600 is still considered one of the best overclocking chips of the Core series.

On the otherhand, 32nm Westmere/Gulftown is the same architecture as the 45nm Nehalem. However it seems this was a lucky dieshrink as it's able to overclock better... Don't forget it was tweaked as well to fit in an extra 2 cores to keep the TDP low.

So really, dieshrinks don't always means higher clocks. It all depends on the architecture. All the dieshrink does is lower power consumption and heat, and sometimes requires less voltages as it's more fragile compared to bigger processes. In IB's case, because of the "3D" gates, this makes the architecture even more compact, so this sort of outweighs the lower heat since there's more circuitry in an area... However, I'm sure Haswell will factor this little problem in and will make full use of 22nm and the 3D transistors. It's best to think of every "tick" as the testbed for the new process to allow it to mature for the "tock". I think everyone was expecting too much from IB...

Guess my 955 upgrade will have to wait until haswell.

Plus the new tri-gate tech which improves over SB clock for clock? and increased memory speeds of IB and is apparently much more stable with all four dims populated, the only down side I see is temp issues above a certain voltage but I will be most happy if a 3570K can get to 4.5 with good temps as it will be a improvement on most 2500k users.

 

[inSilica]

Meh not impressed. Happy with the investment I made with my 3930K, will be with me for another 6 years

but on that SB owners can almost all achieve a 24/7 4.5ghz overclock all day long , IB owners will be happy to go 4.2 , those at 4.5 will be pushing just as SB overclockers doing 4.7/8 , and deff need high end cooling . Its all relative !

Well from what I have read it seems IB reaches 4.5 with ease, it's once going past that and applying the voltage is where things start to matter regarding temps, I think a safe over clock does seem to 4.5 with IB, much the same as SB but with some benefits along the way, I was torn between going SB or IB because of temps and over clock ability but I think the benefits of IB are much more worth going IB especially coming from an older cpu, obviously for a SB user things are different as the outlay may not be justified with the length of time they have been on SB.

I doesn't look good for this release of IB, this place gets moist at the smallest of performance increase, sad to see so many glum faces (well read their words)

So my Q9550 775 setup looks like it will have to remain for a while longer, there is no point going to a 1155 as its dying tech and the new 2011 sounds doomed from the off. I'm not rolling in it, I can't afford to upgrade willy nilly, looks like I'm going to have to wait another year till the next intel release, whatever that is.

Shame AMD can't get it's arse in gear, now would be the perfect time to strike.

The performance of Ivybridge to your 775 is light years i would be looking to get off that as quick as I could its another year before Haswell .. As a sandybridge user i will not be upgrading but anyone on older sockets i would tell them to jump into Ivybridge or Sandybridge as soon as they can CPU only last at best for 2 years with the Intel tick tock model.

 

[jwsg]

The biggest problem is that sockets are only lasting 2 years (one for us buying now).

It's 50% (max) doing them compare charts, but that is both CPUs at stock.

The 3.0 pcie is still interesting since I intend to get a 660 when it's released.

But 50% CPU increase for £500+, not sure it's my time...yet.
