Prime factorization benchmarks (own hobby software in order to try to win
opteron 2.2Ghz : 46.840000 seconds
itanium2 1.5Ghz : 59.180000 seconds
k7 MP2600 : 93.520000 seconds
P4 2.8Ghz Xeon : 137.919998 seconds
(it is embarrassingly parallel software)
RAM doesn't matter for the software, it's just working within L1 cache at
any processor. It's of course like all prime type software utmost tiny.
I do not know about IA64, but for x86 it uses 'cmov' type instructions of
course, in order to avoid branches.
