I thought it was as simple as multiplying the core speed by the number of processors but after reading a couple threads out of the blue it seems that that just isnt the case and now Im a bit confused. I get the assigning tasks bit and the need for programs to be made to take advantage of multiple cores but what about simple spec comparisons? Im refering to the minimum or maximum spec recommendations for games, If a game recommends a minimum of 2ghz, would a dual core @ 1.83 meet that recommendation? Im sure the game would run but I want to know is if the two cores work together to output @ 3.66ghz and go beyond the minimum req. specs. and run more than comfortably or would one core just sit idly by because it simply wasnt assigned (by the game or applicationany) tasks?
I think that when 2 are put together you don't get exactly 2x teh pawaa. But i think the example you gave is correct. DualCore 1.83GHz would exceed a 2GHz req. I think :|
core 2 duos are more efficient than pentium 4s which is what the minimum requirements refer to which means a 1.86 core 2 duo trounces even a 3.4 ghz pentium 4. also you do not multiply cores. they both run at the same speed on seperate things so they do not double the clock speed like you are saying
once i saw a interesting comparission between multi-cores:
think in the CPU as a road, the cars are the data, the frequence as the max-speed and the number of tracks as the number of cores, so if you increase the number of tracks/cores, more cars/data will pass but they won't be faster. it's up to the software send data/cars in pairs to take advantage of the multi-core
Note that the reason a 1.86ghz C2D satisfies a 2-3Ghz requirement is because it's more efficient, not because of the multiple cores... of course, newer games are being optimized for multiple cores so the two cores will help performance too.
