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.

Although I think that dude did say just pick a good manufacturer and a 9-9-9-24 kit. The RAM listed above is 10-10-10-30

Efforts to find RAM with different latency were based on the above, which kind of indicated you were concerned about different RAM timings. We ended up on a merry go round. Thanks for clarifying.

the jedec spec for 1333 & 1600 is 99924, anything else requires xmp profiles to be sued.

I can see where that was confusing. I should have put that in quotes or something.

Ok, I'm ready to stop torturing everyone with this.

I'm just going with the kit below, the 9-9-9 that I've already ordered unless you think it's a bad idea.


G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9Q-32GXM

Thanks.

can your board cope with 8GB sticks? check the manual.

the board should be ok; 4 x DIMM, 32 GB is the spec

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.

How much more is the 3930K?

My preliminary research shows that you could together a CPU and Mobo package for $300 more than a 3770K, and you would probably save some money on RAM because with 8 RAM slots on the board you can get lower density RAM. In exchange for a few extra dollars you know you're getting the best video editing package.

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.

Not so quick. Quicksync only works in a limited number of functions in a very limited universe of applications.

Also, does Quicksync even work if you install a GPU?

Definately go with the 3770K.

Reason A: Ivy bridge is clock for clock about fifteen percent faster than SB, and with the same cores and a higher stock clock.
Reason B: IB supports OpenCL as well as Quick sync in the GPU, both of which are used by most video editing programs today. This could give you a pretty big performance boost. (whereas SB only supports Quick Sync; and a slower version, at that).
Reason C: Overclocking is still decent on IB. You should still be able to get over four Ghz.
Reason D: IB is still more power efficent than SB, even if it doesn't overclock as well, which I would assume would save you money in the long run.

It seems like I came up w about $350 more using 3930k but I didn't consider lower density RAM.

You probably saw this article which makes a pretty good argument for 3930k:

I already built with 3770k. I agree that 3930k would be better for video editing if that was the only consideration.

That makes me feel better.

You can't go wrong with the 3770K. I almost went with it. I might still, but I decided to at least explore the 6-core option.

Reason A: Ivy bridge is clock for clock about fifteen percent faster than SB, and with the same cores and a higher stock clock.

This is a doubtful statement, but even if true I'd rather have 50% more cores with a wider memory bus, easier overclocking and 48 lanes of PCIe 3.0.

Reason B: IB supports OpenCL as well as Quick sync in the GPU, both of which are used by most video editing programs today. This could give you a pretty big performance boost. (whereas SB only supports Quick Sync; and a slower version, at that).

This is something I actually know a bit about and I can tell you that, unfortunately, Quicksync is not well supported in serious editing programs. What's more, where Quicksync really shines is at transcoding, which is only the last step in video editing.

What really put the nail in the coffin for Quicksync is that, at this time, it doesn't work at all once you install a discrete graphics card. How many serious video editors, gamers, or enthusiasts don't have one (or two) discrete graphics cards?.

Quicksync is great for transcoding a lot of video from a slow laptop for upload to your iphone or something, not for serious editing.

I wish it weren't so, but Quicksync is not really consideration at this point in time.

Reason D: IB is still more power efficent than SB, even if it doesn't overclock as well, which I would assume would save you money in the long run.

That's an interesting argument. The 3930K has a TDP of 130 Watt, the 3770K 77 watt (assuming no overclocking of course). That's a difference of 53 watts. I will turn off the 60 watt lightbulb in the hallway when I'm using the computer, and come out ahead
