Comparison performance CF-29 1.4ghz and 1.6ghz ?

Hi Forum,
I think about buying a cf-29 for mobile video streaming via hsdpa.
I can find a lot of 1.4 ghz versions for a good prize. But only some 1.6 ghz. And they are more expensive. Can some tell me how big the differnce in performance from 1.4 to 1.6 ghz is?


Thanks a lot

if you're doing mobile streaming, your bottleneck is the internet connection less the actual power of the machine.

I can tell you that my 1.6GHz feeds livevideo.com stuff just fine.

 

I have a 1.2 and 1.6 and I haven't noticed much difference between either. Both have the same RAM.

I just got the 1.2 however. But in all reality, not much noticeable difference.

 

Thanks for your fast feedback.
To canuckcam:
You a right about the internet connection. But i also know videoapplications needs a lot of chip-power and ram. I will parallel use a firewire pcmcia card for video in, a h264 converter/streaming software and a hsdpa modem card for internet connection.Cause i can`t test the CF-29 i don`t know if 1.4ghz is enough for this.

Does anybody know about a benchmarktest from the differnt chips?

IIRC, this family of processors doesn't jump in bus speed until you get to the 1.8 GHZ range; where it jumps from 333 to 533 MHZ FSB. THIS Jump (Wherever the breakpoint is - I'm not sure, and don't have time to research it right now) in FSB speed is where you will see a major difference in computing speed; NOT a few hundred MHZ in processor clock speed. If there IS a major jump from one processor stepping to the next, that is usually why - people who know the processors know that one has a faster FSB than the other.

Others on this forum will know better from daily use than I where those breakpoints are; I'm just offering an insight into WHY a machine with just a couple hundred MHZ difference in clockspeed would be MUCH more expensive than another seemingly identical machine.

Good hunting!

Are you encoding Full VGA at 30fps or something lower. The smaller the picture, the lower the framerate the easier it is. I lot of the overhead could be in the software but I have no problem receiving mobile video streams on my HSDPA card but you also might want to consider a HSUPA card if you are uploading.

 

I will do a live stream with 25 frames/second in 320x240 minimum with h264 codec and good video and audio resolution.
