Eeek. This seems to go against a naive reading of Intel's published
figures. Their UnixWare figures from
http://developer.intel.com/procs/perf/PentiumII/spec95int.htm
seem to be similar to, but not as complete as their Windows NT
figures from
http://developer.intel.com/procs/perf/PentiumII/spec95int_win.htm
which state these results:
Pro200 PII 233 266 300 333 350 400
SPECint95 8.09 9.38 10.70 11.90 13.00 13.90 15.80
Okay, so it's unfair cos the Pro200 there is a 256k cache model,
whereas the PIIs are all 512k, but from
http://developer.intel.com/procs/perf/archive/highend/spec95.htm
512k only brings the PPro up to 8.58.
So either:
a) You're talking about a measure of performance that SPECint95
fails to measure
b) You're talking about the 1Mb cache PPros that I can't find
on intel's web site (and are extremely expensive)
c) Intel's compilers are supergood or cheating :-)
Which is it ? If (a) does that then apply to mouse's application mix,
and if (b) then does that then applly to mouse's budget ?
Certainly to me the figures above seem to make the PII seem to me on
paper to be very attractive as integer compute per dollar boxes. The
only reservation I have from what I see on paper is that is that the
commodity motherboards do not support memory interleave.
