quick sync - wait for ivy bridge?

post #1 of 4
Thread Starter 
I don't know how many of you transcode videos, especially 1080p videos. but transcoding on my i5 750 takes upwards of 10+ hours per movie.
Should I grab a 2500k this Friday (Microcenter has them for $150 USD if you haven't heard) to start taking advantage of the Quick Sync feature? or wait for Ivy Bridge (rumored to be 60% faster than Sandy Bridge. ETA Q1 2012)?

utilizing quick sync is roughly 40% faster than using CPU only on the 2500k

The last tidbit we have is that Quick Sync performance is apparently much improved. Intel is privately claiming up to 2x better performance than Sandy Bridge in accelerated video transcoding or lesser gains but improved image quality.

Quick Sync is really quick. My laptop which uses an i5 2520M converts video extremely fast with Badaboom using Quicksync.

The main disadvantage with QuickSyncis that not all software supports it.

I'm glad this was posted--I hadn't heard of quick sync before. I don't do much BD conversion, but a decent amount of DVD conversion--I'll have to check this out.

OP--I don't know how much it's worth it to pick up a 2500k just for improved video conversion--you'll definitely see a general speed boos, and apparently quick sync can cut encoding times in half--did you plan to upgrade to IB? If so, then I would think waiting a couple/few months might be worth it.

I only started doing HD content transcoding recently. When I was doing just SD material and DVDs I had felt my 750 was quick enough. I really don't see any reason to upgrade as a DVD rip could be done under an hour on my 750. And I am currently very satisfied with my current CPU for other tasks besides HD content transcoding. I do not plan on upgrading to IB at later date if I snatch the 2500K right now. My financial status would not permit upgrading every generation.
