Woodcrest vs Dempsey 1cpu vs 2cpu

TWO Dual Core Intel® Xeon® 5050, 2x2MB Cache, 3.00GHz, 667MHz FSB
[Dempsey]


Given the price is the same, would you rather have 2 Dempsey CPUs or 1 Woodcrest in terms of performance?

Reason I'm asking is Dell is running a 2nd free processor promo on the Dempsey or upgrade to 1 Woodcrest free. No doubt if comparing just plain woodcrest vs dempsey, its woodcrest all the way easily.

It's still an easy choice.. go with Woodcrest.

unless you do alot of highly multithreaded stuff...

the 4 core dempsey would win with most rendering tests


still, you'd probably be better off getting the precision 390 instead and a faster conroe or kentsfield.

I doubt it.

What are you going to be using it for?

It's not an easy choice. It highly depends on what the OP intends to do with the system.

Take a look at the charts below, for example. What you want to focus on is Opteron 144 vs Pentium D 805 and how drastically different the results are depending on usages.

Single-threaded Apps
Multi-threaded Apps

If we hypothesize Conroe:A64 = A64:Smithfield (since we don't have a single core Woodcrest), the chances are a 4-core Dempsey will beat a 2-core Woodcrest in highly threaded apps.

I doubt it would beat it, if it would beat it, by very much.. and that it's certainly not enough to justify the extra power/heat.

There's also the fact that you'd be stuck with 2 Dempseys.. versus having a spare socket for another Woodcrest (identical spec, of course) as funds allow.

It's going to be mainly a webserver running a series of perl scripts that looks to be cpu intensive. There's a lot of disk io activities involved as files are generated every 5 minutes.

Side question, how powerful of a server do u need to run just purely a DNS server with Linux? Will a 7 year old (P3 256ram) be adequate??

More than adequate for just a DNS server. A 486 might even do.

Will the motherboard have 2 processor sockets regardless? If so I say go with the Woodcrest so you still have the option to add one later, and 2 Woodcrests would rule.
