Re: 49K a week comes to 2.5 million a year, that's a respectable amount.
It's nothing more than about 1% of the CPU market. Intel once said a third of their sales comes from the channel, so I would expect the largest North American distributor to carry a lot more.
The problem is people are trying to extrapolate a real time weekly burn rate from a once a week sample. Inventory is always arriving and sales are always going out the door. It can't be done without more samples...
