has any one heard anything about the fusion cloud ?

40w is pretty sexy, if I were so inclined, I'd build a 2p workstation with 2 of those.

I like AMD, but how does this new 40W Opteron compare to a 65W Xeon performance wise? The Atom has shown us that overall low power doesn't actually mean less power used for a specific task, though server chips don't tend to have idle times like a desktop or notebook.

I wish AMD would make a new laptop processor.. The turion is pretty old now and they need some competition against intel in it.. Also I wish they would make another low powered dual core with the new 45nm tech.. if they can get 45 watts and 2.5 ghz out of a dual core on 65nm and on a quad they can get down to 40w i wonder how low they can go with a dual..

I wonder what these things cost.

I upgrded my old opteron 2xx chips a while back and wanted to get the low power version. Aparently low power also means 3x the price. a dual core 2.6ghz chip was $280. a dual core low power 2.6 ghz chip was $800 -- thats per CPU and i have 2 sockets. For the $1040 difference in price I can pay power bills for a long time.

This is absolutely stupid.
If you are talking about virtualization environments then you know that VM/Watt, VM/$, VM/Space are the most important thing. In that is the case then this product is worthless since it cannot handle the same benefits as the new Xeon 5500 does. If you are talking about HPC, then again Performance / Watt is all that matters and in that case AGAIN this CPU is not worth purchasing since it lowers the performance of everything else in your platform that you paid for and you need more of everything to get the same number of MIPS and that would cost you more in power and purchase price. Now with cloud computing it’s all about performance/$ and Guess what AMD? NO Go for Little Green since the same as above applies here. You need to do a better job of marketing with some real numbers behind it if you actually want people to consider you as a solution. Show me how much it would cost me in Power and $ to get a certain performance level and how that is better than the latest from your competition. Otherwise PLEASE don’t make statements that makes you lose all hope in your company.

40watts. That's pretty impressive, low power is always good, but is it worth it? like performance to watt ratio.

I'd love to replace our old optys in our esx servers with these!
The only resource our esx'es get even close to running out of is memory. There's more than ample processing power available for our needs.
