suggestions for new computer
I'm running Windows 2003 server at home. I need fast processor support for
running multiple OS with vmware workstation. Sometimes I'd like to have Fedora and Windows XP up and running. I'm using Vmware to get rid of multiple pc's in the house. Will I see performance increase with a dual core processor with the type of work I do or is a fast single core still the best way to go? I'm more into buying for the best value than paying for something that I really won't benefit from. |

Don't waste time looking at Intel dual-cores as the current crop is not yet true dual core... no crossbar so the two cores cannot communicate or see each other directly..they have to communicate through the Northbridge chip...which is another problem...all Intel chips are still based on P4 technology and still use a Northbridge for IO. The AMD has crossbar, on-die memory controller (Intel? NOT!), L1 (data) and L2 are exclusive, DCA, and the hypertransport bus. Seriously...AMD takes the cake in dual-core. (note to Intel lovers...the one benchmark that every Intel fanatic spouts about video encoding is useless...the app used in that benchmark was a P4/Hyperthreading optimized benchmark. When the Intel dual core had hyperthreading disabled, the AMD beat it's encoding time by over 60%). Bobby |

The 4400+ has 1M caches and it's still reasonably priced for a dual core. The 3800+, 4000+, 4200+ and 4600+ have 1/2M caches which hurts there performance. The 4800+ is overpriced vis a vis the 4400+, it's only 10% faster but it's nearly twice as expensive. |

Also, the cache difference doesn't hurt performance half as much as people seem to make out. http://techreport.com/reviews/2005q3...0/index.x?pg=1 |

Also, the cache difference doesn't hurt performance half as much as people seem to make out. http://techreport.com/reviews/2005q3...0/index.x?pg=1 It's huge, in my tests a 754 pin 3400+ with a 1M cache almost always out runs a 3800+ which has a faster clock and dual memory channels, somethings the difference is two to one. http://www.polybus.com/linux_hardware/index.htm I haven't put the numbers for the 4400+ up but it behaved as you would expect. Each core in the 4400+ runs at the same clock speed as the 3400+ and also has the same cache size, 1M. However the 4400+ has dual memory channels so that on single threaded applications it outruns the 3400+ by about 10%. On multiple threaded applications it really is twice as fast. |
