Dual-Core Xeon vs 2 seperate Xeon on Motherboard
Which is better, one Dual-Core Xeon, or 2 seperate Xeon processors on
the motherboard. (When purchasing a new machine?) thanks |

(When purchasing a new machine?) thanks I'd think there's precious little reason to buy a single dual core Xeon over a dual core desktop chip, and even less reason to buy two single core Xeons over a dual core desktop chip... |

In general, when it comes to base performance, if you are looking at Dual CPU's vs a single CPU of Dual Core, then the Dual CPU's will always perform faster as long as the speed is the same on both systems. If the actual Dual Core was to have COMPLETE FULL, UNSHARED PATHS in/out, then there would be little difference. As both single core Xeons would be sitting on the same fsb, there's no advantage over a single dual core solution... |

No, there isn't, since both processors have to vie for the same interconnect, just as two cores on a single package vie for the same interconnect... |

Dual-Core Xeon vs 2 seperate Xeon on Motherboard
I heard that it's actually better to get 2 single core Xeons b/c to get
the speed out of one dual-core you need the software written for it, and currently there is not much available. What are your thoughts? |

All the core still compete for the fsb, but if they're doing it on chip it may be faster. I'm somewhat surprised that no vendor has offered a memory setup with a small L3 cache, which you can't do on AMD. There was an IBM article on a smart memory controller which speeded cache snooping, but I don't find the link. I may have been the one to post it, but I still don't find the link :-( -- bill davidsen SBC/Prodigy Yorktown Heights NY data center http://newsgroups.news.prodigy.com |
