Some short descriptions on the Opteron core, incl FPU: http://www4.tomshardware.com/cpu/20030422/opteron-04.html
http://www.top500.org/ORSC/2002/opteron.html The top 500 site has a nice comparison of a wide variety of processors. http://www.top500.org/ORSC/2002/processors.html#ccNUMA The G5 (aka PowerPC 970) is quite similar to a single core Power4 with
reduced cache size and vmx added on. According to the site, IBM
recommends a single core version of Power4 for HPC to avoid resource
contention in the caches and front side bus. Ian
