thermal Paste was never designed to be a good heat conductor, in fact it's a pretty bad one. The job of thermal paste is to fill the micropores of the contact surface, this prevents air pockets (which when heated expands and destroys thermal conductivity

altogether). It is why you literally have to scrape of nearly all of it after applying

Not quite equal, but fairly close. However, this is only for BF3 multi-player and games that are very non-CPU-dependent. BF3's game engine is dual threaded, the multi-player is separate from the engine and is quad threaded. It's also only this one game because none of the others (to my knowledge) make use of six threads, BF3's maximum. Bulldozer probably keeps up with the X6s despite the X6s having slightly faster cores because it scales performance across it's cores a little better than the X6s (or really, any other architecture, especially if you're running Windows 8, ignoring, living with, or having fixed the Metro problem. This is because Win8 is *aware* of Bulldozer's multi-threaded scaling optimizations).
 
[citation][nom]blazorthon[/nom]As high as my hopes for Piledriver are, I still think that Piledriver will not come close to Ivy nor Sandy in performance, performance per watt, or even heat generation. Don't expect Piledriver to, at best, breach Nehalem performance by much, if it even gets that high. If you don't want Ivy, then Sandy is still the best option, that is unless you want the best highly threaded performance that you can muster at any given budget range, in which case PD might be for you. That is still a big might.[/citation]

Proof? Since BD actually comes close to 2500k and 2600k in most benchmarks that are using all 8 cores how come can't PD come close? Seriously?

Well, considering that I specifically said that with all eight cores in use, the PD eight core CPUs would probably beat the quad core i7s, I fail to see why you felt the need to reply to me. I already knew that the eight core Bulldozer FX CPUs come fairly close to i7s (beating the i5s significantly because they are nowhere close to the i7s for highly threaded performance and even the six core Phenom IIs beat them, but not the six core FXs) in some highly threaded workloads (not all of them, but some). In fact, I can go into very good detail as to the problems with Bulldozer based CPUs and what can be improved, if you like. That is a topic that I have studied very vigorously.
 
So Intel saved the CPU cooler market by altering their technology. Here is a prime example of businesses working together to give the end consumer a hard time.

As for Ivybridge, I bought a 3570k and am pleased with it. MSI's 1 touch overclock gets me to 4.2Ghz at 1.175V and that is more than enough for me. I hope it doesn't "degrade though".
 


It shouldn't degrade. Ivy is good at hitting decent clocks at very low voltages compared to Sandy. It's just when you try to go higher that it will show far more rapid diminishing returns than Sandy, although the end result is they have very similar performance, with Ivy running hotter despite it still using less power. Even then, it's stable. So long as you stay well under 1.4v, it shouldn't get fried (although I won't guarantee that it won't, sometimes *** just happens), nor run into stability problems.
 
[citation][nom]dreadlokz[/nom] 5nm is the fisical limit and 22nm already comes with huge heat problems...[/citation]

If you want people to care what you say, at least try and spell a simple word like "physical" correctly.

 
so much for the 3d power gates that they advertised as power saving and reduce the wasted power etc...

FAIL INTEL, this is by far worser than the BULLDOZER release!!
At least the BD overclocks like a fkn champ and on top of that it keeps up with i7 in multi-thread
and even dominates oc against oc i7 2700k!

Bulldozer doesn't come close to Sandy NOR Ivy in power efficiency nor performance when all Sandy, Ivy, and Bulldozer are overclocked to the max. The i7-2700K can reliably hit almost 5GHz or so stable. The i7-3770K can hit a few hundred MHz less, but it has improved IPC, so the two have very similar performance. The top Bulldozer, the 8150, can hit about 4.5GHz to 4.6GHz reliably. The problem with it? The Sandy has about 50% higher performance per Hz and the Ivy has about 55% to 60% higher performance per Hz than the current Bulldozer based FX processors. So, they beat it out easily, more so than they do when al three are at stock. Sure, at stock the 8150 is between the i7s and the Phenom II x6s which are ahead of the i5s, but the FXs are still significantly behind when all three are overclocked.

Ivy does use less power, especially at load where those power savings seem to hit over 30% compared to Sandy Bridge. It's temp problem has little to do with it's power usage. It is far more energy efficient than Bulldozer, especially at load. It might even be over twice as efficient as Bulldozer, which will need practically 300w just to be over 10% behind the i7s at about 125 to 150w overclocks.
 
its late in the comments, but people are jumping the gun.

Thermal compund cost more than solder

Solder tramits heat better than most TIMs

There is likely a manufacturing reason for this. and the thermal limit on sandy bridge is higher.

I love my components to be as cool as possible, but even hot ivy uses less power, so it isnt thermal loss, and is likely exactly what they said: a combination from the TIM and condensed transistors.
 


Lowering the frequency a little should help if it gets too hot. Ivy's main heat problems are when it is overclocked too much. You might want to take it down to 4GHz or 4.1GHz if 4.4GHz get's too hot. If possible, you could try lowering the CPU voltage instead until it's close to as low as it can go stably and that could help a lot. Remember, although clock frequency hikes increase power usage and heat generation, it's usually the voltage that changes the power usage and heat generation the most.
 


Solder's cost depends on the type of solder (there are MANY different types of solder. They are usually differentiated by being different alloys). A lot of the more heat conductive solders can be a tad on the expensive side. Paste, on the other hand, can be bought very cheaply if you don't mind using crap paste. Perhaps Intel didn't mind using crap paste.
 
[citation][nom]jackbling[/nom] the thermal limit on sandy bridge is higher.[/citation]

Sorry about that, i meant the thermal limit on Ivy is higher; 5 degrees Celsius to be specific.
 
[citation][nom]kawininjazx[/nom]I will be the first to say "meh"Yea, 20 degrees higher on a stock inch thick cooler. If you are going to overclock you can get a decent cooler for a couple dollars, I imagine it would still run within reasonable temperatures overclocked on a cheap aftermarket cooler.[/citation]

Well actually the difference if much greater with good cooler!

The temps (according to your link) are the same with the two chips with the Ivy at 4.7GHz and the Sandy at 5.1GHz (93 C) and there is a mere 400MHz difference with both chips in excess of 4.5GHz. The two then go on to have nearly identical performance. So although the Ivy didn't reach as high of a clock frequency, it did reach as high of a performance level. It's reduced power usage shows greatly when overclocked too. Of course, maybe I misinterpreted it a little considering that my Finnish isn't very good. Google Translate's Finnish is also poor.
 
There sure seem to be a lot of heat problems with several Ivy Bridge CPU's not just the i7 3770k

i5-3550 Ivy Bridge review:
"The thing is i got this cpu today and i installed it onto my case. Then when i boot it up its fine and everything. Then after like 20 minutes it starts to have a black screen, i taught it was my power problem so when i got on, i check the asrock temp sensor in the bios. The temp was 85 and going up by the second by fives. Later did i know it became 100oC then my computer shutted down to keep my proccesor from over heating"

"200 degrees with the heat sink and fan that it came with"

i5-3570K Ivy Bridge review:
"Wasn't expecting the heat

Pros: Fast, big upgrade speed wise from older core 2 duo I had before. Newest tech for reasonable price. Was expecting it to run cooler and more efficient due to hype about new transistors. Waited through Sandy Bridge for this release.

Cons: I'm a mild overclocker and was expecting to get a small over clock on the stock cooler without seeing 90C temps using stock voltages. That didn't happen, 4.0ghz = 90C for me. That's not even a 5% overclock.

They should price this unlocked boxed chip lower and not force users to buy the HSF if it can barely keep the chip cool at stock speeds. I hate paying for something just to have to throw it away.

Took an egg off for this heat issue and pathetic stock cooler.

Other Thoughts: I'm sure spending more money on a serious cooler I can get the temps down. I'm sure for a serious overclocker my complaint isn't a valid one. But I am slightly disappointed in this release given all the hype about being more efficient, then having to deal with this heat issue which seems pretty warm to me even at stock speeds. I was expecting it to run cooler than SB, not hotter."

"... with CM Hyper212 evo, after installing drivers immediately went to 43x100mhx for 4.3ghz, no voltage change..hit 70c and started to worry about the heat issues."

Is Intel going to fix the heat issue or not?
