i7 3770K vs i7 3820

[Penti]

Hey guys, I'm thinking of building a new PC, and have been checking out reviews of new components.. Now I've seen benchmarks (this specifically: http://www.anandtech.com/bench/Product/523?vs=551) that says that the old i7 3770K is much faster than the new i7 3820. Was looking at using the new lga 2011 but thinking twice after seeing that review.

 

Now does the new lga 2011 have anything better (mobo wise) that can negate the benchmark of the CPU or is it better to go with the 3770K with an 'older' mobo?

 

P.S. I overclock, but not aggressively, so the unlocked processor doesn't really mean much to me (in it for the long term, so don't want to overclock to the point that it'll reduce the lifespan of the CPU)..

 

Edit to add: want the 3820 since I wanted to try the RIVE mobo, unless someone here can change my mind..

if you actually look at things again you will see that ivy came after sb-e so the 3770k and z77 mobo is newer than the 3820 on the x79.

It is also vastly cheaper and performs better.

 

 

Depends what you're looking to get out of your system at the end of the day. How much are you looking to spend all up and where can you buy from?

Thinking of spending around 4k on the new PC, but that includes two 1k GTX 690's..

 

I don't have problems spending $400 for a high-end mobo and around the same ($300-400) for a CPU, but don't think $600 for a CPU (i7 3930K) is worth it, specially with gains not as significant as the price.. The rest should go into a new SSD, case, PSU, etc..

 

Edit to add: components are limited here in my country, and there's just a few stores that actually carry high-end parts, so choices are limited, and prices are a bit higher than SRP in the States..

What are you going to use it for? Difference in benchmarks usually doesn't show difference in real world usage.

Mostly for games and some photo editing.. Planning on getting three (3) 1080p 3D Monitors, so, along with the two (2) GTX 690's, I need a processor than can handle games as well..

Bump

 

Any more insights guys?

I'd go with the 3770K every time. A quad on 2011, especially a locked one, is a waste.

If you are doing a lot of video editing the quad channel memory architecture on the socket 2011 SB-E is the way to go. The 3820, while locked can run upwards of 5GHz (Mine does just over that on water) so this may make enough of a difference to go that route. Pop 64GB of memory in and go to town. IB is only about 8% more efficient at best over a socket 1155 SB chip.

But for games and photo editing? I'd do IB.

I know this may sound weird in an overclocking forum, but what about the 3820 against a locked 3770, both not being overclocked? Or if ever, just a very slight overclocking, maybe through a built in OC program (OC genie for MSI, dunno what ASUS calls it)?

Gaming and photo editing would make me lean towards the 3770K with an adequate amount of memory (16Gb or more). As ccokeman was pointing out though, if you have a lot of workstation tasks such as video editing, CAD/CAM work etc. the 3820 would probably be the better choice. You can still overclock the 3820 but are stuck doing so using the bclk (very limited adjustment upwards from 101 to maybe 106-107 if you're lucky) and changing the Gear Ratio.

 

Ccokeman can give you lots of help on this because he did a review on the 3820 and discusses the techniques and limitations in his review of that processor.

The 3820 can actually do better with photo editing if you are doing a bunch of ultra hi-res photography, basic photogrpahy you will not notice the difference. Having run both the IB and the Extreme I can tell you for gaming the difference is none existent. There is no difference in day to day performance. The Extreme does not really shine until you hit the need for the large memory setups and then it is worth the difference.

 

For 90% of users I would say go IB, but even better is to go Sandybridge and even considering going i5. Prices are falling the performance is so close as to be identical in real world use when compared to IB.
