Difference between an P4 XEON and regular P4

[jn1167]

Ok,

I would really like to know what are the real differences between the P4 XEON and a regular P4. Is the only difference between them the fact that the Xeon has SMP and the regular P4 doesnt? Or is there something more?

Please give me the facts. LOL

Thanks

Another difference AFAIK is that xeons (or at least p4 ones-i'm not sure) all use HT or something similar, whereas only the newest p4 has this.I may be wrong but that is certainly something i have read.Please correct me if i am wrong because i would not even claim to be sure on this.

no matter how hard you try, you can't polish a turd. :]

Depends what type of XEON you are comparing.

Some types have an additional L3 cache for use in server type applications.
XEON's are certified for SMP operation.
XEONS also have a completely different socket design. IIRC 670 pins compared to 478 for the P4.
So dont think you will be running a XEON on your P4 board matey!

Thanks guys for the info.

I was only asking because i wanted to know what were really the differences in performance. I have 2 server that are using P4 Xeons and Im considering switching to AMD's.

So performance is my real concern. I want to keep the dual processor set up but I think I might be switching and I wanted some input on that.

Well athlon MP's can be used in SMP boards. They are good, though not as fast Mhz wise as XEONS.
The advantage of course is that AMD cpu's are faster doing FPU intensive calculations and dont cost as much.

It depends on what you're doing. Anandtech put up a very good review of database and transaction servers pitting Xeons against AthlonMP's. Both did fairly well in their own rights. With things like Database transactions, HT can really help out in dual processor configurations assuming you're either running XP Pro or higher (a .Net variant maybe) or Linux with kernel version 2.4.2 or higher (I think).

you can polish a turd, you just let it petrify a bit first.

Here is an old article describing the difference between a P4 and the P4 Xeon SMP processor (not the new P4 Xeon MP).

Hey, Thanks for that article. It was super helpful in explaining a lot of stuff.

Thanks
