I need to buy a CPU and mother board. I want to build a very energy efficient server.
Total power used is an important criteria as this is going into a server that will run 24x7.
I have done experiments and have a few data points.
1) A Core 2 quad at 2.4GHz (Q6600) is more than powerful enough for this application, in fact it is over kill. but the TPU is about 100W and it does not seem to be good as power saving modes. 100W is unacceptable. I've measued the power it uses and can't get it to go below 95W.
2) An Atom D525 at 1.8 GHz was fast enough but it is limited to only 4GB of RAM and my application needs at least 8GB to run well and could use 16GB. So Atom is not going to work.
The best I've found (but not tested) is an Intel Core i3-2100T 2.5GHz. Intel claims a TPU of 35W which is 1/3rd the Q6600 but more then double the Atom's TPU. 35W would be Ok if idle mode were much less then 35W.
Of course, what I want is a 2GHz dual core Atom with a TPU of 4W that accepts 16GB of RAM. I doubt such a thing exists but maybe someone here knows of "the next best" CPU"
This is for a server that will connect to the network with a 1000BaseT network connection (gigabit Ethernet) and once it can "flood" the ethernet port by writing at "wire speed" there is no need to go faster. But I do need more RAM than 4GB.
