You realize that you are calculating that 54% performance increase between chips with two different clock speeds?
The scaling is almost perfectly linear:
Single CPU: 63 seconds
Quad Core: 19 seconds
63/(19*4) = 0.82
So there is about an 18% decrease from theoretical max.
The 8 core AMD HT enabled system shows a 4.73x (best case) speed up with 8 cores.
4.73 / 8 = 0.59
Which is a 41% decrease from theoretical max.
Which one do you think is scaling better?
Interesting eh?
Well,期待AMD的真四核带来比这还高的提升率吧 |
