Program pentru testat procesoare multicore

eu am facut 2 teste: unul cu cateva programe deschise: mozilla Firefox cu 8 taburi, nod32, Winamp si uitandu-ma la procese - desktop window manager. Am windows 7 32biti, AMD Athlon 64 x24200+ 2.2GHz, 4GB RAM, si am obtinut asta

                      1,53 x faster than by using 1 thread (1,53 ori mai rapid decat folosind 1 fir)

                      1,12 x faster than by using 2 threads (1,12 ori mai rapid decat folosind 2 fire)
al doilea test a fost doar cu tabul acesta deschis si cu antivirusul si cu acelasi desktop window manager.

are cineva idee ce s-a intamplat? :))

Core 2 Quad Q9550 @ 2.83 GHz
Vista Ultimate x64

L-am folosit cu Everestu deschis ºi nu se vedea clar care core îl foloseºte; încã din timp ce folosea primul proces îmi arãta cã utilizarea tuturor 4 urcã, iar apoi câte unul creºtea mai mult apoi cobora, crescând altul. Când a început testul cu douã, iar au crescut toate un pic ºi vreo 2 tot jonglau. La 4 la fel.
La 1 proces, utilizarea totalã era pe la 20%, la 2 pe la 40% iar la 4 pe la 60%.
De asemena am observat cã doar dupã vreo 6 secunde de teste frecvenþa urcã la 2.83 GHz de la 2.00 GHz, fapt ce ar explica de ce are timp mai mare decât procesoare din serie mai veche cu frecvenþã mai micã.

Am facut un update programului. Acum calculeaza si folosind 8 core'uri si calculeaza altceva.

i7 740qm. Mi se pare ciudat ca nu calculeaza si pt 8 threaduri corect, desi procesorul accepta HT. Adica mi se imposibil sa scoata fix acelasi timp si cu 8 threaduri si cu 4. Se descurca acceptabil zic eu :)

Am descoperit un mic bug. La using 8 threads afisa tot timpul de la using 4. Am reparat si reatasat versiunea noua.

                      1.04 x faster than by using 4 threads (1.04 ori mai rapid decat folosind 4 fire)

Este vorba despre un Intel Dual core E2220 de 2.40 GHz.
E bine/rau?

Merge de 2x mai bine cu 2 threaduri decat cu unu, deci e bine.

Am facut si eu testul cu ultimul programas updatat.
Acesta este primul rezultat cu AMD Athlon II X4 640 3.0GHz, Windows Vista Home Premium SP2 x86

Iata si testul cu CPU - AMD Phenom II X6 1100T 3.3GHz , Windows 7 Home Premium SP1 x64
