Memory bandwidth is just a touch higher than the XTI 3.6's, but well behind the desktop Athlon 64's.
Memory latency is never going to be fantastic with processors that run on mainboards with discrete memory controllers.
Both a Pentium M 770 and Athlon 64 4000 comfortably beat out the fastest Pentium 4 CPU, in terms of clock speed, at least.
