Quote:your saying forget the i7 series cause they will do worse then the i5 series?
I didn't say that . There are 3 generation Core i series :
[color=#00ffff]Nehalem[/color] < [color=#00ff00]Sandy Bridge[/color] < [color=#ff0000]Ivy Bridge[/color]
i7 , i5 , i3 are nothing without the model number behind it
i7 930 2.8GHz is 1st gen Nehalem (4 cores 8 threads)
i5 760 2.8GHz is 1st gen Nehalem (4 cores 4 threads)
i7 3930k 3.2GHz is 2nd gen Sandy Bridge E (6 cores 12 threads)
i7 2600k 3.4GHz is 2nd gen Sandy Bridge ( 4 cores 8 threads)
i5 2500k 3.3GHz is 2nd gen Sandy Bridge (4 cores 4 threads)
i7 3770k 3.5GHz is 3rd gen Ivy Bridge ( 4 cores 8 threads)
i5 3570k 3.4GHz is 3rd gen Ivy Bridge (4 cores 4 threads)
With Hyper Threading (8 threads or 12 threads) + max out the capabilities of all core : [color=#00ffff]i7 930[/color] > [color=#00ffff]i5 760[/color] ,[color=#00ff00]i7 2600k[/color] >[color=#00ff00] i5 250[/color][color=#00ff00]0k[/color] , [color=#ff0000]i7 3770k[/color] > [color=#ff0000]i5 3570k[/color] ,[color=#00ff00] i7 3930k[/color] > [color=#ff0000]i7 3770k[/color]
Dolphin doesn't care about HT . No matter how many core your CPU have , Dolphin only uses 3 cores .
Dolphin :[color=#00ffff] i7 930[/color] ~ [color=#00ffff]i5 760[/color] , [color=#00ff00]i7 393[/color][color=#00ff00]0k [/color]~[color=#00ff00] i7 2600k[/color] ~ [color=#00ff00]i5 2500k[/color] , [color=#ff0000]i7 3770k[/color] ~[color=#ff0000] i[/color][color=#ff0000]5 3570k[/color]
and[color=#00ff00] i5 2500k[/color] > [color=#00ffff]i7 930[/color] , [color=#ff0000]i5 3570k[/color] > [color=#00ff00]i7 3930k [/color]
"~" : no noticeable performance , almost equivalent
You can buy
i7 3770k(270$ - Microcenter) which is much faster than
i5 3570k(170$ - Microcenter) in multi-threaded application . But you gain almost nothing in Dolphin .
