[mythtv-users] Celeron processors with MythTV

[Joe Byrne]

I saw the same article and based my decision partly on it.

When I'm recording off my Leadtek card at 320x480 MPEG4 with both high quality settings, top shows mythbackend at 90% utilized.

Any ideas what the perf issue could be?  Michael--are you running from prepackaged binaries?

  There's a nice article on Tom's Hardware Guide about the Celeron 2.0 (the fastest when the article was written).  They hated it for 3D games because the performance was so far behind the same-cost Athlons, but found that video and audio processing is dominated by clock speed and therefore the Celerons did quite well.  The bottom line is that you should be fine, and the same-speed Pentium should be significantly but not hugely better.

    You probably have some other performance issue. I just built a pundit 
    with a 2.4GHz Celeron. When recording 480x480 MPEG4 with increased 
    quality settings from default AND playback of pre-recorded show I have 
    55-60% idle. I also have to BT tuners and can record both without 
    noticed (yet) drops. I haven't tried playing a show while recording 
    two, but should be able to since playback only takes 3-5% CPU.
