 specFP is a pretty reasonable, widely-reported benchmark.
 here are some scores:
 	cpu		clock	specFP
 	pentium-m	2260	1375
 	athlonxp/1800	1533	671
 this is pretty reasonable- the athlonxp is several years old, with slower
 memory, small caches, lower clock, no sse2, etc.  (vs the pentium-m which
 is a pretty agressive (if originally laptop-targetted) cpu with large cache,
 higher clock, lots of replicated functional units, etc).  for comparison:
 	pentium4	3733	2118
 	opteron		2800	2344
 the latter is a nice workstation/compute-server CPU, and you could
 legitimately expect it to be at ~3-4x faster than the athlonxp.
