You are throwing out the fact that the amd64 has additional features in 64-bit mode that can significantly increase performance.

This is a huge advantage that will hopefully be exploited more as time goes by. Tim has my extreme gratitude for adding Linux32 support. It has been a great help to me. FreeBSD32 support not so much. But I really miss a JVM and Eclipse. Maybe one day I will have the time to pursue this. Sean (one satisfied amd64 owner)
