CPU usage on MacPro 2010 5.1

Post by Sisko125 »

Description of problem or question:

Just wondering why some task (encoding) uses almost 100% cpu while others uses only 50% cpu even though I have the same encoding specs "Very Fast 1084 F30 ". The log below is the file that hits 50% cpu usage. WHY??


Steps to reproduce the problem (If Applicable):

Just change the file to another one


HandBrake version (e.g., 1.0.0):


1.2.2

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):


Yosemite 10.10 Mac OSX

Re: CPU usage on MacPro 2010 5.1

A number of factors affect CPU scaling. Resolution in particular might be for your case. The lower the resolution the content, the less threads will be saturated.

Regardless, it's normal to see wide variances depending on settings, source and hardware. With high core counts as you have your more likely to see it. Older Xeons in particular have weak single core performance so can actually cause bottlenecks as well.
