Pentium D VS XEON VS Dual Core XEON

[jimbo505]

I have seen the performance numbers between a Pentium D and a Pentium 4, but looking at new servers and would appreciate any help I can get...

So I'm looking for CPU benchmarks on the difference between 3 different processors.

1. Pentium D 2.8
2. Xeon - 800 bus 3.2Ghz 2Mb cache
3. Dual Core Xeon 3050

I know what the price differences are, but is a Pentium D a lot slower than a Xeon single? And a Dual Core Xeon make a Pentium D look like a Celeron?

I read some reviews that most (not all) of the time a Dual core can be faster than 2 singles (dual processors) But with the Xeon, I think it's a whole other ballgame?


Thanks!

a lot of programs that aren't made to run on a server won't use more then one cpu, so if those programs are going to be exicuted, then a dual or quad core processor is better then 2 or 4 xeons.

but as for a dual core vs. 2 single core processors, i assume the dual core is faster simply because any communication between them wouldn't have to go through the motherboard and be limited to the bus speed but is instead completely internal...

but i don't have any benchmarks to back that up...

i have never seen any charts compareing those processors becuase they are completely different markets...

The two cores of the Pentium D series communicate over the FSB too.

I purchased some Xeons before but hate the fact they were a lot more expensive and I know one of the programs can use the dual processors - mail software.


There was 1 article I found so far:

It says they benchmarked the systems and I can only assume that they did things right.
