Re: UltraSPARC versus AMD

[William Yu <wyu@xxxxxxxxxxx>]

Looked on AMD's website. 132 for 4x875 on Windows, 126 on Linux. 
(Probably Intel compiler on Windows, gcc on Linux.) That gets AMD into 
the $100K 16+ processor Sun system area in terms of performance. Of 
course, Sun still has a crapload of other uptime/reliability features 
built-in to their systems.

TIP 2: you can get off all lists at once with the unregister command
