If someone was NOT going to overclock, wouldnt the i7 3820 be the better choice over the 2700K?

Advantages: (i7 3820)
Cheaper ($300 VS the $360 of 2700K)?
X79 motherboard
10 MB Cache VS 8MB
3.6GHZ VS 3.5GHZ

Disadvantages: (i73820)
130W instead of 95W
Not fully unlocked(but doesnt matter becuz I do not plan to overclock)
 
The cpu may be cheaper but what about the motherboard?

And I would not assume the 3820 to use 130W. It will use more than the 2700K (both at the same clocks) because of the increase cache but not 45W more.
 
2600 if you're not overclocking. x79 motherboard will obviously cost much more than equivalent z68 boards.
 
is there some bench? It will be an interesting comparison. Wait ivy, will be faster than sb-e, or take a 1155mobo nowif you can't wait
 
Seems to be some X79 Motherboards @ newegg for $229, anyway..

I dont have a computer right now so I need to decide:

3820 now, then upgrade to Ivy-E
OR
2700K now, then maybe upgrade to Ivy

I will be buying a P67, not Z68, i have no need for the extra features on the z68, they will never be used
 
Tsumi brought up a good point

If you know you won't be overclocking, why not just get the 2600 (non K)? You will save about $60~70

Do you know the other benefits of X79? If not, I don't see any reason to consider it. Even if you do know of the benefits you should consider them to see if they are worth the price premium.
 
Why get the 2700K instead of the 2600K? The tiny clock speed bump isn't worth the price premium. For that matter, why not just get a 2500K, unless you are doing something that really needs hyperthreading. You can get a 2500K and a Z68 motherboard for just a little more than the price of the 3820 by itself.
 
Okay, x79 boards are starting at $229 for entry level. You can get enthusiast level P67/Z68 boards for that price. Entry level P67/Z68 boards start at around $100 I think. With most Z68 boards costing the same as their P67 counterparts, I see no reason to get a P67 over Z68 boards.

Since you're not overclocking, why not get a H61 or H67 board? To me, it's kinda stupid to buy an overclocking CPU and not overclock it. Same as buying an overclocking motherboard and not use it for overclocking.
 
IF you need a computer now it's 2700k by default. The 3820 isn't launching until later this year.
 
Tsumi is right. why pay for an unlocked CPU is you don't plan on using it. Get a H67 + i5 2500. The value of an i7 depends on what you plan on doing with your rig
 
If you know you'll utilize Hyperthreading, the 2600 and Z68/P67 whatever board pulls your fancy. If not, get the 2500 and you'll save a boatload. Both would be excellent setups and the price premium for the 3920, which isn't even out, isn't worth it unless you plan on running triple-SLI/Crossfire (which to be fair would be a situation that would greatly benefit from overclocking).
 
The only reason this will make sense is if you plan to upgrade it late to a 6 or 8 core or need the extra memory/Sata ports.

Do you really think you are going to utilize the potential of i7 3820? If not better go for i2700K. 130W vs. 95W is a significant difference between them however prices obviously tend to drop over time.
 
No! Why waste your money when you don't have to? Go to your local Microcenter and pick up a combo 2500K and Z68 motherboard for less than $250 and you have all the power you need. I run games on SLI @ 2560X1600 on this setup and it's faster than my I7 920 @ 3.8 ghz. Wasting your money on a 2700K or X78 set up is just stupid.
 
IMHO, there is one overwhelming advantage to X79 (and that's only some mobos): 8 DIMM slots. That's huge if you need the RAM. Otherwise... I'm waiting for IB-E.
 
I for sure want hyperthreading

Also, I didnt explain myself well, I will probably overclock, BUT do not need/can hold out on overclocking until Ivy Bridge-E

I want to go x78, just incase IB-E does come out with a 8 core, cuz I want to jump on that

The octocore IB-E is still up in the air but if it does come out and if it does perform as "expected" I won't care if it is an EE that costs $999. Unlike the 3960X which is questionable at the price, an LGA2011 rig with an 8 DIMM slot mobo is gonna be mine! :D
 
SB-E might not be the overclockers dream, it is being reported that overclocks are somewhat mediocre. If you want the ability to OC and do it well SB and IB will most likely be your best solutions. However you will have to give up HT for that.

You do not have to give up HT, look at the 2600k and 2700k.

What you are giving up on is 6 and 8 core processors with SB or IB in terms of processor capabilities.
 
The 3820 is a better choice if running 3 way sli 16x16x8, 40 lanes vs 16 on 1155.
If running only 1 card 1155 is the choice.
 
X79 offers:
Quad-Channel memory
40xPCIe
newer motherboards that support PCIe 3.0

Its the clear choice... if you can wait for the 3820 and PCIe 3.0 cards to come out (sometime in Q1 2012)

for you but not for the masses.
actually LGA1155 mobos supports PCIe 3 so what the point?
Click to expand...

you can get an LGA1155 board with PCIe 3 support now but the cards aren't out yet, and when they do come out the 3820 will be out also.

You will then kick yourself for getting stuck on 1155 when 2011 offers alot more upgradability and the 3820 may even be cheaper than a 2700 is now... I'm just saying, waiting a few months will pay off
 
Why does everyone forget about the non-K varients? If you are not going to overclock, don't get an unlocked chip.
 
K models will most likely be easier to sell when you do decide to upgrade...2500k or 2600k ...alot of people on this forum will jump on a K model over the non K...

LOL @ your misinformation.

Ivy will in NO FREAKING way be faster than SDB-E. Ivy-E might.

Depends on your definition of faster. It may have IPC improvements that could very well make it faster clock-for-clock (depending on how multithreaded the test is), and it will almost certainly clock higher. It's not like SB-E is some kind of world-beater.

Dont worry about the power that it TDP which has nothing to do with power consumption.
It is the amount of power the package is designed for.
If you look it up, you will see that the 3820 has the same 130W TDP as the 3860 which runs at a faster speed and with more cores.
 
And alot hotter, i went from 3960x back to 2700k and glad of it, more core speed at lower temps, very lil software that i use anyways, uses 6 cores, save ur money and heat of 130 watt hogs
 
Is there any review of I7 2700K vs I7 3820?

The 3820 has really few overclockability, I don't think that it will be a good bet.
 
I havent seen the 3820, didnt know was released yet, I have seen 3930k, as for the 3960x, just imo a replica of 990x, 4.8 max i could get out of it, and high temps hence 130 watt chip
 
I think for most people still on x58, going to a used i7 970 makes more sense to me. Similar performance and similar power consumption, just a slightly more limited overclock.

The only reason the 2700K is more expensive is because it's an expensive chip. The 2700K has never made sense from a price/performance standpoint. Add the 2500K and/or 2600K to the picture and there is little reason to get anything else IMO
 
Personally I just picked up an Asus P8Z68-V PRO/GEN3 and 2600k. I've been waiting to upgrade for quite a while as my current system still runs very well, but the bug caught me during the holiday sales and I need something new to overclock. :)
