This sounds nice, gives hopes that one day building a 1000-core cpu will

used from internet for the cost of pocket radio).
My question to everyone here... How many years until we have a
1000-core cpu (or something equivalent) as a household desktop
computer? My optimistic estimate is within ten years or by 2020. And
what exactly would the number crunching/calculating power of a
1000-core cpu be?
I thought at first such a machine would simply be 500 times more
powerful than let's say a current dual processor computer, but
considering each individual processor may easily be a hundred times as
powerful as a cpu now, I would think this hypothetical machine would
literally be thousands of times more powerful than an average pc from
today. Oh, and what about price?
I'm looking forward to being gee-wowed!!! : )
