Mike, EDITED The Semprons are trickling in - why no volume in the low parts?
If indeed some tightness exists in the market for AMD CPUs in some places, as some sources suggest, the lowest-end parts would likely be the most affected, as that´s where most of the volume is, and AMD would make sure that there´s sufficient supply of the higher priced parts first before addressing the low-end.
Thanks for posting, things look very consistent across the three major lines (Sempron, Athlon 64, Athlon 64 X2).
