Default CPU for Edius 8: 4790K or 5820K? (Quick Sync vs. 6 Cores)

Two CPUs keep popping to the top of my theoretical build:

4790K - 4 cores, with Quick Sync
5820K - 6 (slower) cores, no Quick Sync

My understanding is that with Edius 7 (and presumably 8), video cards don't matter so much, and more cores are better. So I'd planned on building a system around the 5820K.

But the press announcement for Edius 8 goes on a bit about hardware decoding of h.264 4K via Quick Sync, which of course the 5820 doesn't support. So I'm wondering if a cheaper 4790K build might not ultimately be a better choice?

Then again, I'm ALSO reading that software-based rendering gives better results than Quick Sync, which leads me, Escher-like, back to the 5820K.

Any advice in making a choice? Thanks.

Personally, if you are wanting to move to the X99 platform, the 5930k should be your entry point. This will also give you 40 pci-e lanes vs 28 with the 5820k.
Then there is the 5960X which, by my experience with it, runs cool even at 4.4GHz on water.

As far as the video card goes, if you are going to be using 3rd party plugins that use the graphic card to drive them, the faster the better. If you're just using native effects, a decent card like the GTX 960 combined with the fastest chip you can afford will do the job. You might be able to find a 770 or 780 for a decent price now, but that is older tech. The next generation of video cards isn't that far off.
All this depends on what you will be doing and what type of files you will be editing.

My original build had the 5820 - changed to the 5930 for the 40 lanes, worked well for me!

Kris,

I just went through this with the help of Jerry. I went with the 4790 chip due to Quicksync and being underwhelmed with the more expensive chips in shear clock speed and single thread performance.

In the end, I do not see that much difference between all of the chips unless you compare the 4790 and an overclocked 5960 in a multithreaded encoding situation. Then the $1,000 chip has a nice $700 benefit.

Do you overclock? Because these chips really need an overclock to get performance gains.

My opinion on PCI lanes is that one does not need them unless you have PCI cards. My external preview is through USB 3 and my RAID is from the motherboard, so I still have 4 lanes open. So do not let PCI lanes make the choice for you unless you need them.

It seems Intel has really pulled the reigns back on performance gains between chip releases. If you can wait, I would see what Skylake brings to the table as you will have a new socket which will give a drop-in CPU upgrade path down the road.

Tell us more about your usage and the forum can help pick out the system.

All very helpful.

I've updated my signature to show my current setup. As you can see, it's pretty old, and I'd like to think ANY of these chips would offer a performance boost...though please correct me if I'm wrong.(I'm asking only because Edius shows 16 logical processors, and it performs well with AVCHD.)

I got a nice performance boost when I added a second Xeon, and a huge boost when Edius 7 was released. But my next camera will be 4K, either Canon or some flavor of XAVC. And my system already chokes on 4K from my now ex-GH4. Hence the upgrade.

The higher-end 6-cores are out of my budget, and with new sockets and architectures on the way (thanks for pointing that out) I'm thinking it's expensive overkill for my non-professional needs. (Oh, and I don't overclock.)

So I guess I'm wondering if, in terms of basic 4K native usability, would the additional 2 cores of the 5820 make enough of a difference to warrant the cost of X99? And does Quicksync offer any gains for timeline manipulation?

Again, thanks.

How much faster will be H.264 rendering on 4790K with Quick Sync feature in compare to 5820K (12 treads) or 2x Xeon E5-2620 (24 treads) ?

Will it be faster? Is it comparable?

I have done some tests comparing the Haswell with the 5930 (6 core) and 5960 (8 core).

Comparing EDIUS encoding:

10 minutes AVCHD @ 1920 encoded into 1 pass VBR Blu-ray H.264

4790K with Quick Sync- 2.06 mins
4790K no quick sync - 15.19 Mins
5930 - 15.31 Mins
5960 - 12.47 mins

However, I also use the TMPEG plug-in with EDIUS because it can do x.264 and two pass encoding. This uses all the cores of the processor.

The speeds using this plug-in and a 1 pass encode (to match EDIUS)

4790K - 11.21 Mins
5930 - 9.58 Mins
5960 - 8.14 mins

Which proves that more cores are useful if you have an encoder which uses them.

When doing H.264 in software (with no Quick Sync) EDIUS does not use all the processing power in the way that the TMPEG plug-in does. When playing back video off the timeline EDIUS generally uses all the power of the CPU.

The EDIUS software and Quick Sync encoding look the same quality to me. The TMPEG Encoding is better at lower bit rates.

If H.264 encoding speed is the most important thing then you can't beat quick Sync.

These tests were with EDIUS 7. I have not done the same on EDIUS 8 yet. With EDIUS 8 you have Quick Sync assisted playback. I did a section about that in my what's new in EDIUS 8 video.

I have seen a reasonable difference on a laptop so far, not so much on a desktop. It does not make the laptop into a super computer though. IT means I can manage 2 layers of UHD instead of one on the laptop. I need to do more testing and see what happens with future versions of EDIUS 8. The Quick Sync playback only affects video with H.264 compression. No other codecs are affected.

The 4930 has no Qick Sync.

I think he meant 4790K not 4930 as he was doing a comparison between the standard Haswell and the Haswell-E

Whoops. Changed my original post. I was using the 4790K with Quick Sync. I tried taking the Quick Sync out of the 490K and super-gluing it to the 4930 but it did not work. ;-)
