The Celeron is an HP Pavilion and the P4 is a Sony VAIO desktop. Sorry, no power readings there, I can't shut down the sony and the HP is in a different room. I've added EPIA M 9000 tests to the list (I just got it in today). I'm actually surprised that the M 9000 doesn't have better ram bandwidth with its DDR ram, but the cpu suds are a definite improvement over the EPIA 5000 and power consumption is still reasonably low. The EPIA 5000 still seems to have the best performance/power ratio though. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
