That's what bothers me about the x86

mess due to tacking it all on. Intel EM64T: it's amd64 so 64-bit with

an 8-bit architecture and so on...
Yes it is. However, it has thrived when simpler, cleaner CPU
architectures have failed. Possibly an exemplar of the "worse is
better" school of thought, possibly because of its installed base of
software, possibly because of the tools, chipsets etc. - or possibly
because of the strength of Microsoft, who knows.
POWER is bigger and runs hotter these days.
SPARC and MIPS were unable to compete on CPU performance.
ARM never competed on CPU performance since the end of the 1980s, but
did on performance/Watt and price.
Alpha coulda been a contender -- maybe -- but I learned recently that
its inter-CPU comms, synchronisation and so on were, I am told,
terrible, being very basic and rather unreliable.
