I have always been wondering where those week 46 and 47 batches ended up, until now.

The batch# (3847..) ended up in this new high-end CPU. Some other guy got a new w3565, with batch#: 3846 too.

It seams Intel has stored away week 46 and 47 to be used on hight end chips later. Finally some revaluations on Intel's batch-business is emerging .
