Please compare LGA 2011 to LGA 1155

[red454]

See sig. for current setup.

Considering an upgrade (giving my son my current MB and CPU) and I am wondering how much faster / better the X79 motherboards are. The processor I would use is the i7-3770K.

My gaming habits are moderate (COD4, BF2), but I would like to be somewhat "ready" for newer games in the next couple of years and I know that regardless of what MB I use, my video card will need to be upgraded too.

I may simply go to a Maximus V Gene, but perhaps it is worth a little more $ to jump up a level?

I plan to stick with the ASUS ROG series of MB's and I have compared the ASUS ROG boards and chipsets, so I have a good understanding of all the features.​

The i7-3770K is an LGA 1155 CPU. LGA 2011 processors are the 3820 (quadcore), 3930K and 3960X (hexacores). No advantage to upgrading your 2600K, wait for Haswell next year.

Right - sorry - I meant the 3820 for the LGA 2011. If I stayed with the LGA 1155, then the 3770 would be the one I would use.

And this would be a Christmas project, so I won't really be able to wait for Haswell.

 

[kleinkinstein]

It's no upgrade off your 2600k if you'rr OC'ing. It's an unnecessary and expensive sidegrade, at best. Wait for next Christmas. Wait for Haswell or Ivy-E.

 

[tweakboy]

Big time side grade. It's just another option, NOT a faster option.

 

[abekl]

Agree with the others. A totally unnecessary "upgrade." Wait for the next generation of chips. Even then, it might pay to skip one generation if you really want to get some true performance benefit out of the upgrade.

 

[red454]

Ah, I see. But the situation I am in is this:

Wife's computer is dying, so I will take my son's MB and processor (i7-860) and give that to her, which will be a huge upgrade for her. Really, massive overkill for what she does.

Take my MB and processor and hand that down to my son. (Nice upgrade for him).

Which leaves me open for a new MB and processor (at Christmas).

Everything gets handed down and recycled - a win/win/win.

 

[kleinkinstein]

It's money you need to spend huh?! In that case, snag yourself a x79 mainboard with all the accoutrements you want and either a 3820 ($230 at MC) or 3930K, if you need it ($500). This way the board will serve you if opt into Ivy-E in a year from now. I'd skip Ivy, after all it's only a "tick".

 

[cantholdanymore]

Can you keep your wife's computer for yourself and put it in ER until next year?

 

[dave_the_nerd]

Yeah, why not just fix or replace your wife's computer and get your son a Steam gift card or something?

Frankly, a 2600 isn't that much better than an i7-860, unless you're OCing the heck out of it. If the Nehalem would be "massive overkill" then something like this would be more in line with her needs, probably be "nicer" (OEM prebuilts are usually quieter and cooler-running than the gaming rigs I see most enthusiasts put together) and avoid any potential "OH CRAP" moments with playing motherboard-musical-chairs.

 

[Goresplattered]

i built my computer in may. I went with the 3820 CPU in the asus x79 deluxe.....

http://www.techpowerup.com/mobile/reviews/ASUS/P9X79_Deluxe/13.html


...I am more than satisfied. the 3820 runs stable o/c at 4.6ghz and this board has every single bell and whistle available - except thunderbolt. I have had zero issues with either piece....no rmas...no whines...nothing. bios setup is easy with several options to get you going, and the BIOS itself can be explored with a mouse.....its amazing.


this is the only computer I've ever built and I never found myself confused on what to do next....everything was very easy.

First of all, unless you are considering the i7 3930k, there's no point of lga2011. The 3820 is a good chip by all means, but its not worth the investment of the socket imo. The i7 2600k, 2700k and 3770k are much better value and investment on 1155 imo.

Socket 2011 is best catered towards enthusiasts, workstation users and those who are into video editing/encoding extreme photoshop and run intensive programs because of the large memory bandwidth. For gamers and most users, I think it's best to stick to 1155..It's a great platform.

 

[Shmee]

Don't mean to hijack this thread or anything, but I am also considering between a new z77 or x79 build.

My concerns are this, I have a PSC on my asus motherboard from Fry's, so I would like to use that credit towards a new CPU and mobo. So I must buy from Fry's.

I am somewhat torn between z77 and x79, and the pros and cons are as I see here:

x79:
-motherboard more expensive, but processor (3820) cheaper than 3770k
-would need to order a new retention kit for my water block, about 10 bucks
-would likely be able to use all 6 sticks of my RAM (or would there be any issues with a tri channel kit?)
-upgrade path to IB-E possibly

z77:
-cheaper motherboard, but 3770k is pricey-er and runs hotter when not delided
-would need to get a socket 1155/1156 bracket
-would only be able to use 4 sticks of RAM
-no upgrade path

Also, the board must be able to support crossfire with 1 slot between the dual slot cards (for cooling)

I have been considering the MSI boards z77a-GD55 and x79-GD458D. Boards should be at or under about $250.

Any thoughts?

 

[kleinkinstein]

The 3820 is less expensive than the 3770k for a reason, it's inferior especially from an IPC perspective.

IB-E will use X79A anyway for native usb3, additional sata3, and T'bolt. Akin to X58A, so as compelling as the upgrade path appears, just know that X79 today is really a pisspoor featured board. Someone said it best above, if the 3930K or 60/70X isn't your proc then skip X79 and go Z77. The best plan at this very moment is to wait for Haswell, March-May. If you can't, then option two is to pull the trigger now on Z77 and just ebay the proc and 1155 mainboard when IB-E drops in a year from now, since that chip is likely to make up for all the Ivy OC sins and also be an octocore with 16 threads. It'll likely be the last E chip too, so the features and OC'ability should be stellar.

Best Z77 board for the money is the UD5H, only $130 at MC when you but an Ivy chip.

 

[red454]

Well, really what I have works fine now. Built as a gaming computer, it does run SolidWorks, and it only gets a little laggy on large assemblies. But I can't complain if I am using what was built as a gaming computer as a workstation.

I didn't really plan to upgrade for a long time, but the chance is hitting me sooner than later. (see post 7) So I am just trying to see (from what others have done) what makes the most sense and get the most life out of the 'hand-me-down' components. Wife and son are not techie on hardware like I am, so they could care less what they get.

I fooled with some mild OC'ing, but stock speeds handle what I do.

So I can stay in a nice comfort zone with an Ivy and a well-optioned Z77 board in the sub $300 range. And even though it is a dead end street, it should still be relevant for 3 or 4 years, meaning a nice video card upgrade and I can play most anything out there now and in the immediate future.

It seems that the X79, although more powerful and reasonably 'future proof', might be a little more crude, or rough around the edges, perhaps - at least until some more refined chip sets are released.

Of course it would be nice to have the 40 PCIe lanes, the quad channel ram, and the x16 / x16 for dual video cards in my pocket. Upgrading to a mega core monster CPU, well, I don't think I can justify the cost. A 3820 would probably do the job, and most seem to say that if you aren't going to go with a monster CPU, then why bother with an X79.

And really, I suppose that answers my question. (Sure, I'll flip flop a few times before Christmas :whiste

 

[IntelEnthusiast]

The big thing with the X79 and socket 2011 processors is that they support quad channel memory. Which is nice for high memory applications like video editing but does almost nothing for a gaming system. For a gaming system I would use the Intel® Core™ i5-3570K and put the rest of the money in a good video card and/or an SSD.

What is your current cooler? If you need a new bracket for your cooler, it might be worth looking at Asrock boards as they have multiple mounting holes so not needing a new bracket.

As to the 3820 vs 3770K, the first is not really overclockable, and it is about on par with a 2500 IIRC, so it is definitly slower than a 3770K.

6 sticks can be used in the s2011 board, but for full advantage you will need a s2011 board with 8 slots (some come with only 4 for better ram overclocking) and still have to find 2 more matching ram sticks.

re upgrade path, neither have a very good upgrade path currently as both are about end of their life. IB-E will be a IvyBridge for s2011 so it is expected the Ivybridge replacement cpu (due first) will be faster for home users. Added to that, if you check the price of current SB-E cpus, that is the expected price points intel will place the IB-E cpus at, so if those higher end SB-E's scare you, avoid the s2011 path.

 

[bunnyfubbles]

i7 3820 is a sidegrade, but fully capable of matching whatever your 2600K is able to do, and would be the path I would take if I were in your shoes

The advantages would be in the platform:
1. you would have more PCI-e lanes for adding expansion cards
2. more RAM slots if you choose a motherboard with more than 4 (most have 8, although the two less-expensive ROG boards only have 4)
3. best chance for upgrading CPU in the future

the last point is the most valid, especially if you go with the i7 3820. While there's no guarantee that IB-E will be compatible with current X79 motherboards (although all current indications suggest they will be), if you go with the i7 3820 you will still be able to drop in a 6 core SB-E to upgrade the 3820. There would be no such option for s1155 as it is going to be replaced by s1150 with Haswell, and also no guarantee that the Haswell platform will offer an upgrade in CPU performance for those who already have a high end intel quad.

Really, the primary reason to go LGA 2011 for you would be to give you a platform ready for being adapted to the future, while the primary reason to go for 3770K would be that its likely a slightly cheaper alternative*, and really neither platform will offer much of an upgrade

*assuming no Microcenter option and keeping similar motherboards, the ASUS Rampage IV Gene is $90 more than the Maximus V Gene, although 3820 is $30 less than the 3770, for a net $60 more to go LGA 2011, although who knows how prices with change by the time you will be ready to buy

there's quite a bit of misinformation here

SB-E has BCLK straps that allow for BCLK overclocking, and thus while the i7 3820 does not have a fully unlocked multiplier (of which it still allows some play because of turbo), it can still overclock to the same speeds as other Sandy/Ivy CPUs. Heck, its stock multiplier (36) plus the first step up in BCLK (133 up from 100) yields an 'easy' 4.5GHz, with plenty of room to find combinations for other clockrates higher and lower, its just a teeny bit harder than only changing the multiplier.

as far as RAM goes, you don't necessarily have to have matching sticks as long as you run them at the lowest common denominator, heck, many X79 boards allow you to supply each channel with varying voltages to help with that syncro

and as far as upgrade path, if anything s1155 is currently dead in the water with no real upgrade opportunity in sight, whereas s2011 and X79 currently looks to be compatible with IvyBridge-E which will likely offer 8+ cores as well as the likelihood of solder TIM and thus superior overclocking to 1155 Ivy. On top of that, while an i7 3820 would be a sidegrade, the platform would still have the potential to upgrade, even if its not to IB-E there's still 6 core SB-E like the 3930K, and very much an option to buy one used off of someone (like myself) for a fair price once they make the upgrade to IvyBridge-E. On the flip side there would be no such option with a 3770K rig, as Haswell is going to be a new socket and likely won't offer much CPU performance improvement anyway now that intel is making a pretty significant shift to improving iGPU.

LGA2011 is a platform that will always be behind. Its gonna be SB_E vs Haswell-DT...just plain ugly.

Basicly there are only 3 reasons to use LGA2011. You require more than 4 cores. Need more than 32GB memory. Or you need all the PCIe lanes to add your 4 GFX cards plus raid controller.

Anything else the platform is very inferiour to LGA115x.

unless intel can give us a solution to the thermal limitations imposed on us starting with Ivy, Haswell ultimately will not be any better off for enthusiasts who already have a high end Sandy/Ivy quad, and if you bothered to read the thread, Haswell isn't going to be an option for the OP, this talk is strictly between current s1155 vs current s2011

and you're greatly exaggerating when throwing around "inferior", the only truly noteworthy advantage s1155 has over s2011 is TRIM over RAID-0 if yo have a 7 series chipset (such as Z77). However Intel has long since announced that X79 will eventually see the same treatment with a future update to the RSTe drivers

You do know a 4.5Ghz IB is like a 4.7-4.8GHz SB right? Plus there are aircooled 5Ghz Ibs out there, just like the handful of SBs. Plenty of SBs that can barely get 4.2Ghz.

So no, for 4 cores, IB is superiour in all terms. Including working PCIe 3.0.

 

[bunnyfubbles]

You do know a 4.5Ghz IB is like a 4.7-4.8GHz SB right?

yup, that's why I'm not too upset to settle for 4.5GHz on my own 3570K, however it would have been a whole lot sweeter to hit 5+GHz that many of us thought would be more reliably done with the move to 22nm (whereas 5GHz is still very rare regardless of Ivy or Sandy), as 4.5GHz on my 3570K keeps it from being an true upgrade to my old 4.8GHz i5 2500K rig

Plus there are aircooled 5Ghz Ibs out there, just like the handful of SBs.

I don't know of any Ivys that can hit 5GHz without a delidding mod or supercooling. From what I've seen, the move away from solder pretty much guarantees 4.7GHz is about the best you can hope for on air or AIO water, whereas 4.7GHz was my low for all the various SB rigs I've worked with, including my current SB-E, the 2500K I mentioned earlier, and two 2600Ks.

Plenty of SBs that can barely get 4.2Ghz

what, on stock cooling and/or complete garbage motherboards?

So no, for 4 cores, IB is superiour in all terms. Including working PCIe 3.0.

No, without fluxless solder, Ivy's average performance after overclocking is only "as-good-as" Sandy, and thus the only advantages one can see would be lower power usage and PCI-e 3.0, the latter of which my SB-E supports.

 

[Shmee]

My cooler is the Swiftech Apogee XT Waterblock on custom loop. I am leaning towards getting 1155 and an MSI Z77A-GD55 since I think I found a backplate for 1156/1155.

I realize that both are decent overclockers, and my cooling is pretty good, but I would be curious as to what other overclockers have gotten with a similar cooling solution. I am not interested really in delidding.

 

[AdamK47]

I'm willing to bet my "inferior" x79 system is a better performing gaming PC than most z77 systems on here.

 

[lowboyee]

I'm willing to bet my "inferior" x79 system is a better performing gaming PC than most z77 systems on here.

Trot out your specs and we'll match it to some Z77 systems to see who would win that bet.

While you're at it, trot out how much your system cost and we'll compare that as well.

*edit* Saw your sig. Well, with 3 HD7970s, I wouldn't be surprised if it performed better than Z77 systems in games.

*edit 2* Almost $2500 at today's rates for just the CPU, MoBo, RAM, and GPU according to PCPartPicker and the cheapest versions of everything that I could find:
