Dual processor questions...

[jagr10]

I'm trying to understand this dual processor thing.

1)Is it two regular cpu's on a motherboard with 2 slots?

2)Which quality motherboards support dual P4 cpu's and which ones support dual Thnderbird (1.2 GHz) cpu's?

3)What's faster? dual P4 1.5 GHz or dual AMD 1.2 GHz?

4)Is there anything special (certain power supply or fans or case) that I need to make sure I buy with the dual cpu's?

 

[thorin]

1) Yes (slots or sockets)
2) To the best of my recollection there are Dual P4 boards out by Intel at least. Dual AMD processor boards aren't out yet.
3) Dual AMD 1.2s
4) Case, PS, Operating System must support Dual Processing (Linux, NT4, Win2k)

Also make sure the CPUs are the same stepping. I've seen high end servers that allow chips from different production runs to work together but most workstion level ones need matched processors to prevent problems.

I cant wait to see dual Tbirds just OWN the PIV 🙂

Damn since when did they come out with the Dual P4??:Q

lol,
how can you guys say they are faster if they dont exist??

sure tbirds kill the P4 in RC5, but what are Dual boards really built for?

SERVERS

Id like to see a real world test, perhaps some day we will actually get to see a Dual Tbird and run this test:

System 1
Dual P4 1.4 Ghz
Intel Dual P4 Board
1GB PC 800

System 2
Dual Tbird 1.2 Ghz
Dual Mobo from whoever makes it, probly via
1GB DDR

Systems will have the same Disko I/O

Software:
Win2k Server
SQL Server 2000
MS Test Databse, 50,000 records

The Test:
6 PIII 550 Webservers, all on the same lan, simulating web traffic and querying the DB, all at once, with lots of complex query hits. See which server handles it better. My money is the AMD will fall behind before the Intel will.

Well since Intel actually makes motherboards too, they pretty much released the dual P4 board right after the P4 was out.

 

[jagr10]

so you can't use dual processors with Win ME or the upcoming Window Whistler?

 

[Windogg]

Windows ME is based on the Windows 9X kernel which does not support SMP so the second processor will only be heating the case. Windows &quot;Whistler&quot; AKA Windows 2001 AKA Windows XP will support SMP since it is based on the NT kernel.

 

<< so you can't use dual processors with Win ME or the upcoming Window Whistler? >>


With Whistler (Windows XP Pro) you can use dual. With ME and Windows XP Standard you cannot.

Well if there is a dual p4 board then why don't you link it up instead of just talking like i actually know this or something?😕

&quot;Damn since when did they come out with the Dual P4??&quot;

Did some hunting, I was incorrect. No Dual P4 baords are available at this time.

[UThomas]

That would be because the P4 is not SMP compatible.

[Hanpan]

t was a big deal when the p4 came out. Like coppermines early stepping will not support smp. However later steppings and foster (p4 server chip like xeon to p3) will.

 

[A2KLAU]

I would say that the P4s, witha few tweaks, will outrun the AMDs if they are built for server useage. I mean Intel are Legends for having their CPUs included in servers am I right in saying so. I mean if the boss goes to you, what CPU would you recomment for the next ipgrade, you say AMD, then youw ould get the sack, casue Intela re the most reliable. AMD are only good for home PCs or workstations, but the heart of the system should be an Intel so i would imagine Intel would win that test out of both the systems!

[LuNoTiCK]

I would go for dual p3's.

 

[Sohcan]

As UThomas and hanpan said, the P4 is not SMP capable...it's been disabled in Willamette. That feature is going to be reserved for Foster, due out later this year. As with all Intel server CPUs, Foster (and their motherboards) will carry a very hefty price tag.

Anandtech P4 review
&quot;For now this doesn?t matter since the Pentium 4 is strictly a uni-processor part, but it will matter when its SMP counterpart, Foster, is released.&quot;
