The maximum I have seen is 17.3 bytes per clock. This is a likely bottleneck since most instructions in vector code are more than four bytes long.
Does SMT have any effect on this? If SMT is disabled in bios it may fetch 32 bytes. Also in general how IPC is effected for single threaded tests based on SMT bios setting?

Thanks for the great documents.
