Default Please help w/ pros & cons of 6 cores vs 4 cores & QuickSync for Edius 6.5

I understand the benefits of Quick Sync for h264 encoding.

What I haven't been able to get clear answers for from my research is:

1. Is Ivy Bridge h264 encoding reasonably comparable in quality to software encoding? (I'll be viewing on a 92" screen.)

2. How much better would a 6-core system be for editing (# of tracks, effects, general speed, rendering, etc.)

3. How much slower would a 6-core system be for encoding h264 (if Quick Sync will do it in about 1/2 realtime, what's the multiplier for software h264 encoding on a brute-force 6-core system)?

I know the decision boils down to balancing whether h264 encoding or general raw horsepower is more important day-to-day, but I haven't yet found real-world examples to guide me.

Thanks!

Search the forum. There have been multiple discussions on this topic. Not necessarily 6.5, but basically what you are interested in.

I do appreciate the response, but I've read dozens of forum discussions and articles (here and elsewhere), and I've pretty much only heard:

1. Go 6-core/X79 for brute strength in editing.

2. Go 4-core/Sandy or Ivy Bridge for 1/2 realtime h264 encoding.

HOWEVER, I've yet to find any real-world advice as to the precise questions I originally posted here (other than an Andandtech article discussing my first question -- encoding quality).

If you can help me out with some examples, it would be greatly appreciated.

Thanks again.

Have you thought of a systems integrator. You will notice
my signature with the EditHd Ultimax system.
You can contact George@Edithd.com.


There are many of his systems on this forum.

With all due respect to systems integrators and their talents, I'm trying to do this at base cost, and I'm extremely experienced in building systems (and researching the parts). And I can do my own troubleshooting and support after the fact.

But in this case, I simply haven't been able find the answers to those few questions I posed, which would be all I need to make the decision of which mobo/CPU route to go.

Hopefully someone here can give me their 2 cents, particularly since I'd prefer to hear from people using Edius.

Ivy Bridge CPU here, I can say the H.264 encoding quality wise is spot on. Most of the 4-6 minutes projects I do, I just sit there and watch the render, its super quick and saves me much time.

Cannot answer the other questions.

Thanks -- I'm glad to hear you're satisfied with the quality. Maybe someone with a 6-core X79 based system can chime in and tell me about their system...

As you can see in my sig I have a I7 3820 X79 4 core overclocked
, I don't use H264 much so I opted for power. IM sure if H264 encoding is high on the list the Ivy or Sandy Bridge would be the way to go.

1 min H264 Ts at 15M - 1 min 40 secs
1 min H264 MP4 at 15M - 1 min 20 secs
1 min MPEG 2 TS at 25M - 31 secs
