What would be better suited for Rosetta work? I have the option of a 2.6Ghz 2Mb processor or a 3.2Ghz 1Mb processor. Any suggestions would be helpful. The OS will be Win 2003 Server.
Thanks

What kind of CPUs? AMD or Intel? AMD with dualcore or single? Intel with HT or not? Same memory ammount and speed with both CPUs?

And finally, why chose? Just use both ;-)

Intel Xeon, single core, I think both would have HT. Same memory amount / speed. My boss will only let me buy one server :(, so either processor is in his price range.

I'd go with the faster cpu with 1mb cache. . I'm pretty sure they're faster per mhz anyway compared with the newer 2mb cache chips.

Same here, I'd go with the faster one. Yes, cache is a nice thing, but with a memory footprint of about 80 MB per Rosetta instance, I doubt that the benefit from the large cache would outweigh the speed.

Why not look at the comparibaly priced AMD Opteron (maybe dual core version) ?

Although, what is the server actually going to be used for (other than Rosetta) ?

Just a file / document server. The vendor I have to deal with only offers Xeons on their servers :(

Nothing wrong with Xeons, I have two Dells (dual, 3.4 GHz, 2M cache) and they work quite well ... though a quad PowerMac will likely beat them ...

Of course, I saw that Dell is now selling Dual, Dual Core HT Xeons; though only at 2.8 GHz. A little pricey I thought at about $4600 or so ...

In any case, you really don't need that much CPU for file servers. But, the more the better for DC.

but do the auditors know that?

while waiting to serve a file; exactly ;-)
