shrug.  does anyone have serious experience with real apps on manycore
machines?  (I'm familiar with SGI boxes, where 80 is fairly ho-hum,
but they're substantially more exotic/rare/expensive.)

I bet there will be 100x more 4s servers build with these chips than 8s. 
and 1000x more 2s than 4s...

a friend noticed something weird on intel's spec sheets:

notice it says 32GB max memory size.  even if that means 32GB/socket,
it's not all that much.

I don't know about everyone else, but I'm already bored with core counts ;)
these also seem fairly warm (130W), considering that they're the fancy
new 32nm process and run at modest clock rates...
