2700K or 3770K?

I am at odds end on this one... Which to pick?

Given the price difference between the two: 309.99$ for the 2700K and 379.98$ for the 3770K (at ncix.com)

I have heard from a review that they only experienced a 3% overall increase in performance with regards to these two chips (2700K vs 3770K).

My question to all of you is as follows:

- Does 70$ justify the overall 3% performance increase from the 2700K to the 3770K?

Please leave your opinions here. To give you a little background, I'd be upgrading to one of these from a Q6600

what other parts will you be getting? motherboard, heatsink, graphics card, etc.?

i had a 2700k and loved it and played around with 3770ks a fair bit too, so.. the $70 would justify it if you wanted the latest and greatest; 3770k.. but if you're ballin' on a budget and $70 matters, grab the 2700k.

both will overclock to about the same performance.

upgrading to either one from the q6600, you'll be happy

I don't think so. I think if you can overclock the i7-2700K to at least 4.5 GHz (which most can, unless you get a really bad chip), the price difference can be compromised. The i7-3770K on the other hand can't overclock as well as the i7-2700K, and it's pretty much the end production of LGA 1155 (making room for another socket, Haswell 1150, I believe).

Why not get an i5 2500k or 3570 and a 1155 mobo?

There's moneh to be spent!

Here on overclock.net, if you can overkill, overkill.

For a daily driver the 2600k/2700k will generally OC higher on standard cooling, they still CBB by the time they get to -50 or so.
They fixed the coldbug issue somewhat with 3770k, I have one here with no CBB (cbb can be anywhere from -100 - full pot though, depends on the chip) so they are definitely more fun to freeze than sandy & don't have the same frequency hard wall. Also have a better IMC for playing with the memory if you will be looking to bench it.

Ivy draws less power and can overclock just as high and higher with correct voltage settings . With proper Z77 mobo or other gen3 boards you can also take advantage of PCI 3.0 bandwidth approx 2X that of 2.0 .

Wow 379$??? id buy it from somewhere else..

2700k is old tech get the latest and greatest.. 3770k

But buy it somewhere else cheaper.

Plus you get the 2x speed on die gpu with games that use virtue mvp it will be a big gaming boost and video encoding.

If you get one of the boards that can do 16x16x or 8x8x8x8 your getting a cheap just as fast as 3930k besides the very few things that use more then 8 threads for alot cheaper. http://www.newegg.com/Product/Product.aspx?Item=N82E16813128552

also if you go extreme u get this boost..

I see quite a diff ...

I have both the 3770k and the 2600k.. the 2600k was demoted to back up rig..

And um yah the 3770k over clocks just as well as the 2600k....
Cause it does not transfer heat well and has higher temps means nothing IB can take alot more heat then SB it was made this way.... Thus with people whoo know this 4.8ghz - 5ghz is not to hard...

My 2600k wont get stable past 4.6ghz soo um yah..

I have researched the same thing for weeks, and I have come to the conclusion that Ivy Bridge is the better one to go with (though I'm getting the 3570K). The 3770K edges out the 2700K because the die shrink. According to the benchmarks I have read, the 3770K is equivalent to a ~200MHz boosted SB (3770K @3.4GHz >= 2700K @3.5GHz).

I'll make a short pro/con list to help aid in your decision.

3770K Pros
-Faster clock for clock than 2700K
-Use Z77 features to its fullest extent (PCIe 3.0, 4K res., etc.)
-Latest and greatest
-Great overclockability under ice
-Lower TDP

3770K Cons
-Runs hot
-More expensive ($350 vs $310 Newegg)
-Overclocking room is limited

2700K Pros
-It runs cooler than 3770K
-Better overclockability than 3770K

2700K Cons
-Outdated architecture
-No PCIe 3.0 (extra bandwidth only really matters on 3x/4x sli/cfx, and few motherboards support those setups)

It's not always about the sheer numbers when it comes to processors. If you think you can use the features the Z77 chipset provides, then by all means, go with Ivy Bridge.

@Hokies83: You just got a lemon. The 3770K does have less overclocking potential under air/closed water loop and it's mainly because of the heat problem it has, but the performance is generally the same when both are overclocked.

Most people can only get up to around 4.5-4.7GHz with the 3770K/3570K, and the 2500K/2600K is usually sitting at 4.7-5GHz. Even at a lower overclocked speed, people are still getting relatively the same performance compared to SB. As long as you have a really good cooler (Phanteks/Noctua/Silver Arrow/H100/open loop LCS/etc.), the heat problem IB has should be under control. Well, it will be under better control than a lower performing cooling system.

I'd highly advise you take a look at this article. It goes much more in depth about the 3770K than I ever will. On the benchmarks, the 4.8GHz 2600K is faster than the 4.5GHz 3770K, but most of them are so close, its within margin of error. If the 3770K was at 4.7GHz, the performance would have been greater than, or equal to, the 2600K.

No the norm on the 2500k and the 2600k is 4.5ghz - 4.8ghz With afew people breaking that as it has been out awhile so there is many people with the chips so yah there are more ppl breaking it...

3770k Norm is also 4.5ghz - 4.8ghz with a select few breaking the 4.8ghz mark more will come as more people buy them just like sandy..

Anything below 95c on IB is ok so you have more over clock room them you think.

You'll experience higher overclocks with most of the 2700K's. I was in the same boat and opted for it instead of the 3770K. The $70 can be better spent elsewhere in your system. A cooler, a water block, all the misc stuff or even a pump or rad. Or, if you're looking at cases, $70 off of a case you wanted to get.

You gain nothing butter a better built in GPU that you'll most likely never use for $70. If you achieve a higher overclock than the 3770K -- Well, it's a no brainer

Enjoy whichever you choose (I chose the 2700K)

OP was talking about the 2700K which most of them are hitting the 5ghz thanks to the higher bins (I know my 2600K couldn't and the 2700K can do it with ease.. on an H100 vs the 2600K on full water)

IB runs a lot hotter than Sandy and if you think anything under 95c is okay... eh...... we'll have to agree to disagree considering that's almost the boiling point of water. Longetivity of not just the CPU would be my concern if a part is generating that much heat on a chip.

Going with the 3770K is not worth it if the price difference is that big. The latest 2700K chips almost always clock to 5ghz with acceptable voltage, which can't be said of the IB chips.

Besides if you can OC SB around 200 to 250mhz higher than IB they'll be even. So I'd say go with the 2700K and use the saved money on some other components.

Than obviously your 2600K is a bad clocker and your 3770K is a good one. Generally that's not the case.
And can your 3770K stay below 70 degrees in prime95 and reach max 75 degrees in IBT when OCd to 4.5ghz?
Cause my 2600K does that. Room temp - 28 degrees while testing.

QFT. This exactly.

Or find a used 2700K. Seen some go for $250 on other forums.

Well cause you went with an out dated slower chip is not my fault..

I think you need to do some more reading on IB and heat my friend..

IB is made to run like that.. What is the heat hurting nothing.. it is made for it.. LoL..

You have Sandy Bridge with a Ivy Bridge Mother board [Insert face palm here]

You really cant compare IB 1155 with SB 1155 IB beats them in every way..

What needs comparing is Socket 2011 3930x and 3960x which is on Par with a 3770k...

This is the cpus you compare with performance... http://www.anandtech.com/bench/Product/551?vs=552

http://www.anandtech.com/bench/Product/551?vs=443

You cant match socket 2011 performance with socket 1155 Sandy Bridge but you can with Ivy Bridge....
You can even get the 3.0 pci-e bandwidth performance out of Ivy http://www.newegg.com/Product/Product.aspx?Item=N82E16813128552

And most of all people need to quit using Heat as there excuse to justify there purchases of SB over IB..
IB was engineered to run like this.. and the heat excuses are getting old.. and almost funny at times.

nothing wrong with running SB on Z77. Some users got noticeably higher OCs with Z77 and SB. virtuMVP should also run on SB if you want to run that.

Yeah but your missing features and also IB 4000 on die gpu which is twice as fast as Sandys is going to work alot better with virtue mvp.

Im just really tired of hearing the heat excuses as the heat affects nothing.
