Mark Tellez, AMD's server and workstation manager, also showed me a picture of
the Opteron - unfortunately this one was a little of focus but it's worth noting that although you can't see it on the
photograph, it's got the word Opteron printed on top of the CPU.
As for the pictures of the Opterons - I asked the technical guy who was looking after the show why the case they were in was so large - was it because dual Opterons needed special cooling? He said no - in fact this was just a test rig case AMD used for demonstrations, and the Opterons required no special cooling.
Tellez also showed me the latest ATX motherboard for the Clawhammer - intringuingly the "melody" on previous boards people have seen has disappeared.
There's a full size JPG of the dual Opteron system here. ยต
