Not my thread, but I need to set the record straight.
Our ASICs can achieve above 10 GHs. It was just one corner measurement.
At the end, it's system efficiency. I saw three examples of systems based on AM3 in the wild, all of them above 1.1 W/GHs.
Out system is about 0.85 W/GHs at full power.
We've taped out our 2nd gen ASIC, and we'll be below 0.45 W/GHs at the system level in two months.

AM3 can't compete on 28nm, since it's "custom design", which means it will take at least 6 months to produce 28nm. Well in time for our 3rd gen.
Finally, we can compete on the price as well.
