All indications are that K6-2-400s are yielding very well. Indications are that 450s and 475s are yielding reasonably well.

Jim, thats news to me. I haven't seen them publicly state yet that the high speed yield problems are solved, for volume builds.

In any event, life will again get very tough, very soon, as they try to transition to K6-3 and K7. These are both substantially larger die, given they will be built on the .25 process at least into next year. So in addition to fighting the process shift problem that is eating into their high speed yield, they will have the inherent problem of defect densities to drive yield down on the larger die stuff. There's always hope when .18 is mature. But thats at least a year away. Manufacturing is simply killing them.
