What's the difference between Intel Duo Core and 2 Duo? Is T2400 better than T5500?

Question

I am trying to decide between a laptop that has T2400, 1.83GHZ, Duo Core and another laptop that has T5500, 1.66GHZ, 2 Duo Core. Which one is faster?
Thank you very much

Answer 1

the first part of the answer above (the one from Shawn H) is completely wrong. Core Duo and Core 2 Duo have precisely the same range of clock speed.
Core Duo / Core 2 Duo
1.60 GHz: T2050 / T5200
up to
2.33 GHz: T2700 / T7600

the main difference between the 2 generations is the considerably improved architecture of the Core 2 Duo (what makes it the fastest processor atm). to mention are 2 specs
- the L2 cache is fully shared between the 2 cores (no fix 50:50 share, this means in an extreme case one core can require nearly the whole cache)
- the Core 2 Duo series has the EM64T instruction set implemented what makes it capable to run the 64bit Version of the upcoming Windows Vista OS

with these 2 main improvements (+others in the ALU) the T5500 is the faster CPU despite its slower clock.

Answer 2

Intel Core Duo and the Core 2 Duo are very similar. They both accomplish much of the same tasks, yet the Core 2 Duo is a tad better. The Core 2 Duo was released very shortly after the Core Duo. The first laptop with the T2400 is faster. It is probably cheaper too.

Answer 3

The Core Duo chip follows the industry standard for increasing the processor speed as new chips are released. The Core 2 Duo follows a different principle where the processor speed is lowered, but the chip does more per CPU cycle. So it's not a matter of speed but a matter of work.

I'd go with the Core 2 Duo.

Answer 4

The Intel Core 2 Duo is much faster than its predecessor, the Intel Core Duo.

Answer 5

It is a very hard question.....
