[gmx-users] Final Workstation Specs

[Erik Lindahl]

Hi,

Xeon will still do better at double precision due to SSE2, but the 970  
is a respectable chip with two fully indepented normal floating point  
units. The normal performance (without altivec) is almost identical to  
the G4 performance with altivec.

(Altivec does not include any double precision instructions)

Cheers,

Erik
