I'm new here, and my English is really bad, so please forgive me when I'm making mistakes.

I'm planning a home server together, so I need the right CPU for it.
It must be powerfull enough for extracting archives and therefore I wanted a CPU that has a clock of atleast 2 GHz.
Thet Intel Atom N330 is too slow, so I went to the AMD side, I found a Athlon 64 X2 4850e and 5050e.

Now my question is: Which processor should you advice me for my homeserver?
Doesn't there exist an Intel version of the 5050e, or something like that?

I really hope you could help me out.

look at the AMD 250 and 550 BE, they're rated at 65w but some are more like 40w.

I saw the 250 has a TDP of 65 and the 550 BE has a TDP of 80....
I need to pay the energy my homeserver uses myself, my parents don't want to do thas, so I really need a good balance between low power concumption and performance.
On a benchmark at I saw the 250 uses Idle +- 140Watt, I think/hope that that is including the graphics adapter, hdd and mainbord.
How many do you think that processor uses at its own?

Thanks for your replay btw,

^ the 140w is for the whole system.

and wouldn't it make more sense to get a laptop and an external HDD?

I've tought about that, but a laptop with a dual core processor faster then 2 ghz gets pretty expensive.
I've searched for a motherboard that can take a mobile cpu, but there aren't much of them and if there are, they don't have more then two SATA ports...

Thanks for your replay...

Oh, one thing more: which hardware site do you prefer for hardware info? I'm seartching for a site that gives me the really consumption of a processor, not the whole system.

Well, I prefer anandtech because they aren't biased like most other sites, but being a gamer, I don't really look at the power consumption stuff.

The slower Intel 45nm duals don't use anywhere near their 65W TDP.

How about the following 45nm processors?
Intel Core 2 Duo E7200
Intel Core 2 Duo E7400
Intel Core 2 Duo E7500
Intel Core 2 Duo E8200 (i hope this will dont use that much power, because it supports Intel Virtualization Technologies)

Thanks for your time!

well, whatever processor you get, you could downclock and WAY under volt the processor (less volts and less speed, less power used)
