Linux and the Desktop Pentium M: Uncommon Performance

Content Creation
Below, we compiled lame 3.96.1 without any additional optimizations and then used the following command on a 800mb .wav file.# lame sample.wav - b 192 - m s - h - >/dev/null
The file is sent to stdout, which is then directed to /dev/null. We do not want the hard drive to throttle our mp3 encoding if possible, even if we are just immediately destroying it.
Next, we used the SuSE 9.1 Pro i686 bzip2 and gzip RPMs for this portion of the analysis. We recompile both binaries from scratch later to illustrate the effect of the compiler optimizations. The 800MB test file from the lame benchmark above was compressed and then timed using the command below.
# time gzip -c sample.wav > /dev/null
We compiled MPlayer 1.0pre5 from source without any optimizations. The benchmark command that we ran is below:
# time mencoder sample.mpg -nosound -ovc lavc vcodec=mpeg4:vpass=2 -o sample.avi

phaxmohdem: these were just linux tests, but i do believe we have all of those render benchmarks coming up in the Windows analysis.Kristopher

#44: The results could be better on the Windows platform, as stated in the conclusion.sprockkets - Friday, December 24, 2004 - link
If you want to see the clock speed dynamically adjusted just roll your mouse over the kpowersave daemon running in the tray (at least it works for me under SuSE 9.2). Even my little Via C3 800mhz system will scale from 399 to 800mhz depending on load. It may even work in 9.1 (the part I couldn't enable was the suspend options). Hell, SuSE even can make my Hitachi Desktar drive go quiet to performance mode right in the OS!formulav8 - Friday, December 24, 2004 - link
As this article shows, alot of people way overhyped this chip. Yes its not bad, but not the P4 Killer that alot of people claimed.It is interesting but it doesn't look like Intel will make a Desktop chip based on this cpu yet in the near future. Dual cores would be very interesting though.

This chip seems to be a god-send for the corporate IT directors needing machines for their monkeys to do Word and Excel documents on. As for me though, I don't think I could purchase a chip that has as spuratic performance levels as this. I do so many different things on my box, especially in content creation, that I much prefer the consistant performance of my current Athlon64 proc. across all applications.Just a suggestion, I would love to see some Adobe benchmarks on these chips... After Effects render times, Premeire Render times, Photoshop performance, etc as these are all applications I use nearly daily. Thanks.

When someone does a full set of benchmarks of the Pentium M for all categories across the board vs A64 and P4, then I'll seriously consider if this chip is worth its salt. Until then, I am unconvinced that it is anything special. If it is so good, then why hasn't Intel made any attempt to push it as a desktop chip?segagenesis - Friday, December 24, 2004 - link
It was looking pretty good until you mentioned the price :( Ouch.Ozenmacher - Friday, December 24, 2004 - link
