ja testowalem na sp4 asusa i wychodzily calkiem ciekawe rzeczy. w tej chwili
nie mam juz zadnej sp4 na skladzie zeby powtorzyc operacje i przytoczyc
konkretne wyniki, ale w porownaniu z "oryginalnym intel tritonem" i fpm (z
cache! :) ) bylo dokladnie 2x szybciej. fpm w sp4 pracowaly jakies 15-20%
wolniej. testowalem to cachechk'em. ponizej kilka tescikow na t2p4 asusa
(hx) z 512kb pipelined i 32edo (45ns). procek to p133 puszczony @75MHz x 2.5.
twardzielek caviar wdc ac32500h. wymienie po prostu simki na fpm w
poniedzialek i podrzuce wyniki tych samych testow. (pozwolilem sobie
powycinac zbedne spacje, bo mi durny edytor w majlu lamal linie na pol i sie
kaszka robila ;) ).
