BD Rebuilder: Questions about performance, duration etc.

I want to build a new computer. Among other tasks I want to do avc-encoding with e.g. BD Rebuilder.
  • Would BD Rebuilder benefit from a quad core system compared to a dual core?
  • Or is a dual core with higher clock speed more efficient?
  • How important are RAM, HDD performance, OS Windows (32bit or 64bit) etc?

How long does a encoding job take on your systems?
Could you post some results? (CPU, RAM, Settings, duration)

Thank you in advance.

yep in 100% x264 encoder will use all your cores.

Quad core at the same clock will be 2x faster than dual core

CPU is the most important part

I finished a encoding job on my htpc:

AMD BE2350, 2x2.1 GHz, 2 GB Ram, WinXP (32bit)

Swat, [01:57:17.029] , 15,2 GB, MPEG2, 1080p

Settings: x264, High Quality, One Pass (CRF), Target BD-9, movie only

Encoding Time: 20:00 h (!)

@Hobojobo
For movie only on BD-9 I would expect "Better (Fast)" to provide reasonable results.
You may also want to resize to 720 which would speed up encoding time considerably - at the expense of the resolution which you may however find to be still very adequate.

A couple of small added points. A quad core of the the same basic architecture and speed as a dual core will be approximately twice the speed. An AMD quad up against an Intel dual core such as the Wolfdale core won't deliver twice the speed. That being said a decent AMD quad core such as the X4 630 which cost less than a fast Intel dual core will be faster for reencoding because of X264's ability to use all 4 cores, and do it for less money.

@all: Thanks for the input.

I tend to get an AM3-Board with a Phenom II / 905e or similar.

I hope, we can gather some results with different setups (hardware, settings) in this thread.

Speed of different processors with x264: http://www.techarp.com/showarticle.aspx?artno=520
The 3.0 version of this benchmark is only a week old, so there aren't that many results yet, but the 2.0 version has plenty of results and the order shouldn't change.

O.T. (sort of)
Thanks for the link.
I ran the 3.0 Test. I would like to share my test results. I tried to register.

I tried to send a message to the admin but I can't. I cannot pass the image verification of the contact-us-form, 'cause I cannot see the image.
Is it an Asian forum ? Are there characters shown, which my browser cannot show?

Here are my results anyway:
