mmmh... not sure to be sure to understand so tell me if i understand...
two cores doesnt mean double CPU power but double performence.
for example, emulating snes requires 3GHz. i dont know if what about to say is right but its just for example. so 3GHz for snes would mean :
800mhz for models
1000mhz for textures
500mhz for audio
600mhz for AI & scripting
100mhz for other things
if this is for a monocore cpu, would it means that on a dualcore cpu it would be 400mhz for models or it would mean that each Hz used by the 800 mhz for model generation can be used for one more thing, like 800mhz for models so textures would then requires 200 more mhz?
honnestly i'm not sure to understand how cores works. but i was sure before that if you want to compare 2 diffent cpu, like a tetracore 3,4ghz and an hexacore 3,2ghz, you have to proceed with this operation so you would know which one is the most performant :
#ghz x #core = performance
for example, the tetracore 3,4ghz would have a performance of 13,6 and the hexacore 3,2ghz, 19,2
so the hexacore 3,2ghz is better than the other
