Nagging questions about a 3930k build for high end video production

[skaker]

AS for the 2 speed states with x79, I cannot confirm, all I can note is what I have seen so far and I have not seen any states except the max work and being a electronics designer and IC developer, I can definitely say running at max all the time will definitely shorten the lifespan. The transistors were not designed to be used like that, thats why they have speedstep.

It will still not draw much current when idle. It will use significantly more power than if it were able to drop to a lower pstate, but it will not be 'running at max'. Power draw (and current and heat) is primarily a function of load. And the transistors are designed to run flat out. Intel uses the same fab to make xeons, which are guaranteed for 24/7 full load. Speedstep is not designed to increase life span, but to save power (and/or increase performance by utilizing turbo bins).

I also can't confirm if it will drop to a lower pstate, xeons won't and I don't know why a 39XX would be different. The only way to get a non-idle frequency using xeons is to disable EIST and set a frequency. The OS can't communicate with the chip to tell it to speed up, so the only way to get it to run faster than idle is to have it do so at all times. But again, I've never used a 39XX, so...shrug.

I also disagree that nVidia is for gaming as games don't take advantage of CUDA cores, I have been gaming for longer then I can remember and thats why I prefer ATI for gaming and nVidia for CUDA/OpenCL.

I didn't say Nvidia is for gaming. I said 680/690 are for gaming, IMO. Before shelling out for one of these I'd do a thorough research into whether my video apps are going to use all that power. The link I provided above provides some info on that.

The Premiere benchmarks here can also help: http://ppbm5.com/

#1 has a GTX 680
#2 a GTX 275...

Ok this confirms that it is the CPU and NOT the GPU that does the decoding of footage in premiere: http://www.studio1productions.com/Articles/PremiereCS5.htm
This strongly suggests that a 3930k will offer the kind of performance I'm looking for relative toa 3770k

@Sasquatch00 I would be 100% happy with 1/2 or even 1/4 res non-dropped frames playback of 4K and 5K footage. Right now, my slugnet build at best does 1/4 playback smoothly (perhaps dropping the occassional frame). Anything more and it chokes on the files in CS6.

@dtrvndrn I'll need to look into video card research a bit more, especially for Resolve, etc. I'll look at the link you posted.... but I find it a little hard to find a definitive resource that clearly shows how much CPU affects rendering and exporting footage vs Graphics card in something like premiere...

now that's some in depth info to chew on! can someone make this a sticky for all the peops into video editing builds?

You could always build one of these: http://legacy.tonymacx86.com/viewtopic.php?f=169&t=55963&hilit=supermicro
Too bad the pics aren't there anymore.

More like a 1906 Rolls Royce Silver Ghost than a hummer.

Yikes! That's a bit--A LOT--out of my price range :-/ ....I think I'm gonna stick with the 3930k build plan. Ideally, I'd love to create something that mimics the NeweggTV epic mobile pc video editing build... something that is good for transporting from place to place.

I imagine that getting any kind of thunderbolt support for a 3930k build is not possible as current motherboards for these chips don't support thunderbolt???? Is there hope of this for the future?

something that is good for transporting from place to place.

I built a mATX system in this compact case for that reason: http://www.lian-li.com/v2/en/product/product06.php?pr_index=317&cl_index=1&sc_index=25&ss_index=64
I had to be picky with the graphics card to make sure it (just barely) fits under the PSU and HD cage.

Now looking to transplant the system to a 19" rack format so it can be transported in a flight case. There's a discussion on that subject here: http://www.tonymacx86.com/music/77469-vj-live-video-mixing-build-19-rack.html

Nice! That case looks more practical than my Lian-Li. Mine will not fit a water-cooler either.
