Hi guys ...

i need your opinion on the following:

P4 2.66 HyperThread 1Gb RAM

or

Dual P3 1.23Ghz 1Gb RAM

they are for serving high bandwidth usage ... so it would be on a 10Mbps unmetered line ... with around 200 concurrent users online.

Is this a forum?

If so, dual P3 will serve much more btter.

PIV 2.6 with Hyperthreading

My vote goes on the P4

p4 here as well. Given that that revision of the dual p3 has half the cache of the p4, that difference is negated. Hyperthreading works very well with the 2.6.x series of linux kernels with the new scheduler, so that's also a plus.

Best bet would be a dual xeon so that you're not here asking this question in the near future (you mentioned high bandwidth usage, so I figure you have an already popular site - those types just tend to get larger and larger as time goes on ;) )

I would go for the Dual P3 ;)
You will be surprised by its capacity :D

dual p3s outperform single p4s in almost all server applications due to the clean (read unoptimized) implementation of the instruction set.

if you are running linux, single cpu may offer some performance advantages because some code involved in heavy network i/o does not deal with cpu affinity optimally. however, on a 10 meg line, you should hit that cap before you notice the difference.

my vote definitely goes to the dual p3.

The P3 at 1.23Ghz will be based on the Tualatin core, which has 512k L2 cache, exactly the same as the P4. So with two, it will have a total of 1mb L2 cache, double the L2 cache of the P4. It is the Coppermine core which only has 256k.

Id go for the PIII anyday :)

go with the dual p3

I would also go with the dual P3, you will get much more out of it then the P4

Now I'm confused :(

I thought the 1.23 was a 'Willamette' with 256k cache? Ah well - if it is indeed 512 per cpu then the p3 would be a better choice, agreed. Cache is everything.

-David The Willamette was the original (and crap) Pentium 4 core from 1.3Ghz upwards, the final PentiumIII core was the Tualatin from 1.0Ghz to 1.4Ghz after the Coppermine core which ran to 1.0Ghz or 1.1Ghz (can't remember although im sure it was 1.0). The Willamette was replaced by the Northwood core at 2.0Ghz I think although there have been slightly faster models of the Willamette released since.

Easy mistake to make ;)

dual p3

I was just wondering why the option of a dual Xeon was not offered? Surely if you can afford a 100mbps unmetered line, a dual Xeon should be no problem.

dual p3 anyday...
