Hello, I want to setup a small asterisk PBX. Should I use an Intel based system or AMD based system ? Which platform is better suited if at all there is difference ? And if I were to use AMD platform then any issues if I were to use a 64bit arch. Most good boards seem to be for 64bit. My distros in both case would be CentOS. Thanks Varun

If you want to handle, lets say 1000 calls or more at the same time, you should of course use a better processor. In my opinion, it doesn't matter whether you use Intel or AMD, because you said it will be a small Asterisk. Kai

What board, what interfaces (digium/sangoma) and results as well as caveats. Andrew

The AMD CPU will finish performing an instructions a whole 5 nanoseconds before the Intel CPU! When a code is well-written (usually it mean: written by a good compiler) the pipeline delays won't add too much. In other words: this is a nice argument, but until it is backed up by hard data, it practically means nothing. -- Tzafrir Cohen sip:tzafrir@local.xorcom.com icq#16849755 iax:tzafrir@local.xorcom.com +972-50-7952406 tzafrir.cohen@xorcom.com http://www.xorcom.com
Tzafrir, are you trying to tell me that I can realy do double on the intel becuase the second CPU will do it?

As we are talking about pbx boxes (for large office/enterprises/ maybe ITSP?) i think we are using server grade boxes (like hp ml3xx or bigger) I have some servers with fan on cpu heatsink, but most of them are using only heatsink on cpu, and redundant fans. I think, we need some real life comparison to decide, what to choose. i'm not a cpu expert, but who knows, if dual amd is better for transcoding or dual xeon? i think it can as big weight on paralellisation as big weight on horsepower also, don't you think? Another thing, is what to choose? another cpu (so go for dual, or quad) or bigger cache inside? (probably another 3.2G/1M xeon would cost less, than replace the existing with a 3.2G/2M) So i would welcome (and maybe pay for) a real life test what says: AMD opteron will do x paralell alaw->g.729 dual opteron, fx66 and the same for intel pentium extreme, duo core, xeon with 512k cache, xeon with 1M cache, and probably with 2. and also Xeon DP. -- WoodOO-[P]an[G]alaktikan[A]gent-People <][> http://shadow.pganet.com wpeople@shadow.pganet.com]iCQ#33118021[wpeople.on.iRCNet]wpeople@RedHat.users
