Video editing cpu. 3770k or 2600k?

[nottheratboy]

Hi,

Building a computer for video editing, around $ 1500-2000.

I was going to use i7-2600k but now considering 3770k.

I understand that the performance increase is minor but don't understand some of the features like "integrated usb 3.0". If I had a Sandy Bridge cpu I wouldn't upgrade but not sure what to do with a new build.

Also, 2600k is available and $300, easy (?) to overclock.

3770k is not available Newegg and $350. ($400 Amazon ). More difficult to overclock (hotter?)

So my questions are:

1. Would you get the 3770k or 2600k?

2. Will I be able to overclock the 3770k significantly, air cooled in a quiet case like Antec p280?

3. Would you consider the 3770 and not overclock?

Thanks.

Is QuickSync an issue here? If so then the 3770k for sure.

You can definitely get a moderate overclock out of the IB, not as much as the SB but still good 4.2 - 4.4 should be reasonably trivial to achieve.

The biggest issues here are Quik Sync which favors IB and overclocking / thermals which favors SB.

Right now I'm doing IB in lappies and SB in desktops

Regardless of how far you overclock SB any app that uses QuickSync or OpenCL is going to be heavily biased towards IB.

Just depends what software you are going to be using.

So Quik Sync is integrated graphics processing with IB, right? I guess I had read about that and kind of dismissed it because I thought I read a review/test which was unimpressive. That may have been gaming oriented compared to a lower end graphics card though.

Not sure if it Quik Sync will make a difference for me. I going to use a prosumer grade video editor, some of which use gpu acceleration and most don't, so the graphics card becomes another issue.

I can't find the editing program I want to use because my computer can't handle the programs for a trial, but I can't build the computer I want optimized for particular software without taking a guess as to whether it is worth buying a decent graphics card.

Maybe the safer bet is to go with IB as long as I can find it and you think it is overclockable air cooled.

QuickSync in the right conditions will make a HUGE difference.

Here the 3770k is TWICE as fast as the 2700k, and 6 times as fast as itself without quicksync.

Now this is currently only in certain applications, but it may well be that in the future there are more applications that take advantage.

Even in apps that don't support QuickSync the 3770k is still faster than a 2700k (let alone a 2600k).

Why? Because you are using high end graphics cards for the pc's?

For your purpose, I would suggest an i7 3930K, if you can afford. Expensive but you get extra core/threads that will come handy. Throw-in a lot of RAM, with a GPU to suit your purpose, you will have a pretty good system. The MPE loves CUDA cores (nVidia Quadros 4000 upwards) unless you want to use AMD Firepros and OpenCL/GL.

I've OC'd a 3570k on air in a P180B, got to 4.3Ghz, I'd suggest that there is a high probability of any chip being able to hit 4.2Ghz.

I thought about that but I think it's more than I want to spend. It does look great though. Will think it over.

It is worth it if you can afford....otherwise, i7 3770K...

i'd go with newer technology, 3770k even it has 100mhz more frequency, better integrated graphics but as you mention that for editing so external GPU must be necessary for that stuff, heat? Heat will not be an issue when you've a decent coolersomething like corsair h100 (www.newegg.com/Product/Product.aspx?Item=N82E16835181017) so you can squeeze it alot to get more "GHz" i'm providing a link see yourself how well 3770k perform against 2600k.
Ok here it is:

another important thing is GRAPHICS CARD in that budget get a single gtx 680 which i think 2nd most fastest card.

 

[xtreme5]

editing is mostly dependable on amount of RAM memory available for example, if you have 4gb of ddr3 1333 ram and you are compressing a 400mb file with WINRAR suppose it takes 3 minutes when you have 8gb ram it takes 1m and 30sec so increasing the ram will increase the rendering speed indeed i'd suggest to go with G.skill ripjaws x series 16gb kit(2x8gb)

See the choice is very clear....your video editing/rendering is a function of processor power/speed and RAM, unless you want to take an expensive GPU rendering route.

The 3770K is a good CPU for pre-i5/i7. If your video editing/rendering is medium to heavy, I think that you would benefit from the extra cores/threads from the i7 3930K, for which you have got to pay a premium. Once you decide on the CPU (with that the mobo), you can quickly assemble the rest of the hardware.

GTX 680 is an excellent GPU. It is traditionally the gamers card, while pros go down the Quadros / Firepros routes. May be, you can have the best of both world, depending on your requirements.

I had tried to put together a build with the 3770k:

I'll try another with the 3930k. Between MB and cpu price increase will probably be about $300.?

 

[xtreme5]

going with 3930k will not worth there is not a massive difference between 3770k vs 3930k
here is the bencmarks:

Intel made some tweaks to the SB architecture in IB which may help you out. If it were me, I'd wait and pick up the 3770K CPU.

Here's an AnandTech article page that details the changes in the Ivy Bridge CPU architecture - http://www.anandtech.com/show/4830/intels-ivy-bridge-architecture-exposed/2

That's an interesting benchmark. But i7 3930K still pulls ahead in multi-threaded setup, is it not? In Video editing/rendering, the extra cores/threads are bound to help especially if packed with RAM. The difference is cost. Can the OP afford it?

 

[SSri]

But, overall I agree, i7 3770K is the CPU for a new build. But i7 3930K's extra cores/threads would be very useful if video editing/rendering is no longer a lightweight project.

 

[aicom]

Don't forget that you lose QuickSync on X79 platform so you have to determine whether the 2 extra cores are worth not having QuickSync. I'd say if your rendering program can use QuickSync, grab a 3770K. If not and you have the budget, a 3930K will be the better choice.

 

[xtreme5]

3930k is supposed to be good in multi-threaded apps because it has 6 CORES + 12mb of cache so indeed this would be best there but overall performance is neck-to-neck.

Indeed. If the OP's video editing/rendering applications use multi-threaded set up, that's the best choice; Otherwise, it is a waste spending extra $ on the i7 3930K.

 

[xtreme5]

let the OP decide?

Thanks for all of the opinions and information. Kind of a tough decision.

Looks like 3770k over 2600k everyone seems to agree.

Re. 3930k vs. 3770k my understanding is that video editing would benefit from the extra cores/threads as you've said. If we just had Sandy Bridge it's clear that 3930k is better than 2600k for video editing anyway but I didn't know where 3770k would slot in.

Maybe a little below the 3930k for video editing I guess.

Not sure how QuikSync changes things though. Probably depends on the software. The only editing programs I see using it now is Corel Digital Studio and Cyberlink Powerdirector.

Really valuable discussion for me. Thanks.
