Intel Core 2 Duo T5500 / 1.66 GHz equal to single Intel 3.32 GHz?

Hi. This laptops L3K C200 NB C2D CPU power is Intel Core 2 Duo T5500 / 1.66 GHz ( Dual-Core ). Do this Intel Core 2 Duo T5500 / 1.66 GHz equal to single Intel 3.32 GHz?

It doesn't correlate one-to-one. First, a Core2 Duo has a much more efficient pipeline architecture than a Pentium4 or a P4-equivalent Xeon, so its value in GHz is worth more. In a regular Core Duo, you could get an approximation by multiplying by 1.7, but the Core2 Duo is even faster and I'm not sure what the multiplier would be now. If I had to guess I'd say, ballpark figure, 1.8, which would mean that each core of a Core2 Duo is very roughly equivalent to a P4 3GHz.

 

Since this is a dual-core chip, you'd actually be getting the equivalent of a dual-CPU 3GHz P4-equivalent system. In very well multithreaded apps, like most renderers, you'd see a speed about equal to 6GHz of P4, but in apps that are not multithreaded you'd only be getting the 3GHz.

Yeah, it goes something like that....

Simply:

ONE core CPU (notice that all of them are DUAL)

is like TWO TIMES P4 frequency.

 

Example:

E6300 (~1.86GHz x 2) is ALMOST equal P4 D945 (3.4GHz x 2)

Ofcourse, a lot of dependes the software do you use, LS, PS, MAX.......

When i bought a Core Duo...it was almost exactly twice as fast (with just about every type of scene) as a 3.06GHz (with HT) machine i was using before. My Core 2 Duo is around 20% faster than the Duo. Well worth the difference in cost.
