I've not seen the benchmark programs (is the source freely available?),
but it's highly unlikely that any commonly-used program uses integer
arithmetic anything like as much as a benchmark.
That is, a real program is unlikely to benefit by anything like as much as
a benchmark written specifically to test such a feature.
Something I would like to see is some means of ranking the assorted models
of Pentium, Pentium II, Pentium III, Celerons and assorted AMD and Cyrix
processors.
Preferably, something to answer the question:
Does a BP6 with two C400s beat a Pentium III 600?
but also to tell how much faster C433 is than a C400, and where do the Cs
fit in compared with Pentium IIs and IIIs.
