It certainly seems so. The PIV seems to be very touchy about code patterns and the kind of jobs its fed. Gcc at the moment doesn't have PIV optimisations either. The Athlon by contrast is extremely good at handling code compiled for any CPU variant and that meant Athlon didnt need much if any work for performance

Thats fine - your chipset is newer than the AGP code knows.
