CPU (xeon or pentium d)

[SOSAGES2]

Hi all,

i hope someone can help me

Would a two Xeon 3ghz (2mb cache 800mhz FSB) system run slower or faster than a Intel Pentium D Processor 930 at 3GHZ (4mv cache 800MHZ FSB)

rest of the setup is the same (hard drives ram etc)

i understand there are a lot of factors at work and it would depend what the system was doing.

Regards, SOS

(Simply put

Two Intel Xeon processors at 3 GHz with 2MB cache
or
One Pentium D Processor 930 with 4MB Cache

What would perform faster? the dual xeons or the single pentium d)

Think the cache is split between the cores on Pentium D so on single threaded apps no real difference, both running 3GHz with 2Mb cache. In multi threaded apps two sockets with single core CPUs will out-perform a single socket dual core, so the Xeons will be faster but not enough to outweigh the big difference in cost.

Only other thing that might make a difference is that a lot of Xeon boards need ECC RAM and there's a slight performance hit for the extra protection of ECC

yeah xeons aren't bad chips, but there expensive, the 3Ghz nocona models are 150+ pounds and there just a multi-CPU pentium 4 with a few revisions, and too many boards require ECC memory with socket-604, opterons are worse with that still

Edit: answering your question the xeons would likely be faster, theres a brilliant iwill SLI board for them but it cost a fair wack

Unless you already have the chips, a woodcrest 'core 2 ' xeon would be so much faster that its not even funny. So would a desktop 'Core 2' processor.

or if you needed server system ASAP with dual processors dual opterons is a good rig as well
