absolutly ^^

good meal + short night = digestion and a hard time to keep my eyes opened ^^

So josephH: i'm sorry for reading too fast
wolfy : thanks for correcting me

I will try to read more carefully ^^

Hehe, it's no problem mate.

At least a good explanation came out of it. ;p

correct. we propose the single core since it's more powerful
and less power (energy). we are working right now on the next
generation of the dedicated servers that we will propose in
2-3 months: very powerful and no energy when no activity.
right now all CPU consumes energy 24 hours per day, even if
there is no activity. with 45nm the costs of energy will be half.
but it's the futur (2-3 months). now you have single core
celeron 220.

!= means does not equal so josephH agrees with you handmousemaster.

You're wrong

The celeron 220 is a single-core processor @ 1.2GHz, but with a FSB of 800 MHz and a 512 KB second level cache. The Core microarchitecture improved processors' usage of both available clock cycles.

So with half the frequency, you have better performance (the processor makes 2 calculation when the old celeron only makes one. So the new celeron makes as many calculation as a old processor with twice its frequency) and a processor that need half or less of the power of the old one.

@ OVH: they might be right, even if the processor is better, some clients might use this in a wrong way. So maybe you can specify something to explain that... but while i'm writting that i thinking it's non-sense: a bad client won't try to understand why a processor with a lower frequency can be better, so good luck with that point ^^

Ah ok, the marketing people should really rethink how CPUs are branded. As freq seems so far actual processing power maybe it would be better to measure them in MIPS or something.

> The processor is 1.2GHz though isn't it?

you can get an old one with the old cpu: celeron 2.0GHz
or the new one with Celeron 215 (1.3GHz) or the very
new one Celeron 220 (1.2GHz).

It's the new generation of the CPU: Celeron 215/Celeron 220.
It's the single core Celeron. It's more powerfull (+5%) that
the old generation of Celeron (Celeron 2.0GHz/2.6GHz).

I said you: Ovh is the innovation ... The very new hardware ...

The processor is 1.2GHz though isn't it?

I think the cpu is lowering its multiplier to minimize power consumption.

The kimisurf product is advertised as 2ghz, is this a machine specific issue or am I missing something here such as intel's version of powernow?
