You mentioned 20% performance boost. I think you overestimate the performance gains. What I said was not the same as what you said to the dot. YOU are the one talking down to ME. I've been patrolling 6200 posts in this thread since its inception to try to help people.

How is it, then, that three other people understood the question but you did not? 

 

The Cinebench results show a 20% gain over Sandy, as well as several other benchmarks.

So you still think I'm talking down to you? You want to revise that statement/position? How come other people understood but I do not... If you're not going to bother clarifying a query, go to some other thread. If you respond my original reply meant to help, with lots of info with, 'this was completely useless, read what I wrote', etc etc, those snide comments are not welcome here. Cinebench results show a 20% gain over Sandy? At the same clock speed, yeah. You think the average OC for Haswell is 5ghz? The only way you can really tell what the average Haswell OC is with my chart because it's the only chart I know of ATM with picture-verified settings, clock settings averaged, charted, for all to see. Else you're most likely guessing what the average OC actually is.

 

You come here for help. I'm not doing this back and forth BS anymore. Count me out of any future replies to you.

Suppose so, it's all down to what temps your are comfortable with.

In my post, I quoted Sandy. I was on a 2600k, though I just quote he 2700k benches because nobody cares about my poor old weak processor laughingsmiley.gif. The Visual Studio gains in particular appealed to me. I have also noticed a significant reduction in rendering time for other programs I use. You had answered my question perfectly, though.

 

In regards to 5GHz, I have a friend who literally burned through four Ivy 3770ks trying to OC beyond 4.6GHz on air cooling. Now, Ivy is different from Sandy, but even with Sandy I kept  myself at 4.5GHz even though I could theoretically become stable at a higher one. I don't like running warm let alone hot. I made some pretty awful OCing mistakes as a teenager and learned my lesson from them. But it just seems to me, and this is just what I have noticed anecdotally, that a lot of the people railing against Haswell don't even OC their Sandy/Ivy chips beyond Haswell's majority limit of 4.5GHz (after which people start to find it's unstable if they have a bad chip). Doesn't mean they need to buy Haswell, just their opinions about it sucking for power users are silly.

HWBot's average OC for 2500k is 5.037ghz, 4.551ghz for 4670k. The 4670k result actually completely agrees with my chart statistics. So Haswell is 20% all around faster with 500mhz lower clock speed?

 

Fun. Sandy can't hit 5ghz listed in HWbot but Haswell obviously CAN hit the 4.5ghz listed in the hwbot, right?

 

I can't justify purchasing Sandy to Haswell, but new build before that era makes sense. What part of my verdict changes? If you really, really need that CPU power then there is always Ivy E.

In terms of average clock speed shown in HWbot, it actually looks more optimistic for Sandy i7 vs i7 but realistically is about same situation for i5 vs i5. If you concede the earlier points then that would mean Sandy i7 is 20% slower than Haswell i7 due to the hyperthreading. That's the only reason I can think of right now. That only then applies to hyperthreaded applications. Which one, I would like to see multiple sources demonstrate this fact, and two, would only of course, limit you to hyperthreading. The word around town is that Haswell can be pretty hot, hotter than Sandy, so if you don't even like to run things warm, then it's going to be an issue. And if you like to run your Prime before declaring the settings stable, you will have a hard time doing much with Haswell at all.

In terms of average clock speed shown in HWbot, it actually looks more optimistic for Sandy i7 vs i7 but realistically is about same situation for i5 vs i5. If you concede the earlier points then that would mean Sandy i7 is 20% slower than Haswell i7 due to the hyperthreading. That's the only reason I can think of right now. That only then applies to hyperthreaded applications. Which one, I would like to see multiple sources demonstrate this fact, and two, would only of course, limit you to hyperthreading. The word around town is that Haswell can be pretty hot, hotter than Sandy, so if you don't even like to run things warm, then it's going to be an issue. And if you like to run your Prime before declaring the settings stable, you will have a hard time doing much with Haswell at all.

 

My claims bout the 20% in the first place was in regards to why I had personally chosen to upgrade from my Sandy i7 to the Haswell i7. Not that Sandy was overall 20% better. I would never make such a claim!

 

I am averaging in the upper 70s in Prime @ 4.5GHz. When doing normal applications (VS, video and photo editing, Folding @ Home, etc) I never see myself go above 60c and usually hover around 40-50c (this is during load). I am in the process of converting to water cooling, though I was always planning to do that regardless of Haswell (TBH it was my GPU that pushed me towards the decision). I always thought I held fairly normal standards on keeping things cool, but as it turns out a lot of people seem to be shockingly okay with CPUs that hit 70c+ at normal load (non stress testing). On here there are folks who want the coldest case possible and I definitely want to join that party. No liquid nitrogen for me, though.

Well, it's not neccesarily the end of the world if you're hotter than 70c. AMD's quoting full lifetime for their 290 and 290x running at 95c for example, that is many years under sustained 100% load. Haswell won't stop you from running at 97c 24/7, i think 73c avg on hottest core isn't too aggressive (under full load) for a 24/7 OC though it's not freezing either

AMD runs hot in general, and I always assumed it was just better at *ahem* taking the heat coolsmiley02.gif. The temps I ran back in my AMD days long ago would probably give me a heart attack if I saw them in my computer today. 

 

But high heat with Intel over extended periods of time can cause damage, no?
