'3dnow' is an AMD marketing term. (and is long obsolete)

Nor did you answer (or understand) my sentence above: 'sse' is an
x86 specific term.

I think a naming and enumeration scheme around the general concept
of 'vectored co-processor' would be far less x86 specific.

Mockup:

19583739 vec-adds ( 2.01x scaled)
20856051 vec-muls ( 2.01x scaled)
20856051 vec-divs ( 2.01x scaled)
25100224054 vec-idle-cycles ( 1.99x scaled)
12540131 vec-busy-cycles ( 1.99x scaled)
42286702 vec-ops ( 2.01x scaled)

Paulus: would this categorization fit PowerPC too?
