[camang]

hi

i would like to know wich processor is better..... intel i5 or core 2 Duo??? cuz i'm planing to buy a vaio notebook with the core i5, but i've heard that core 2 Duo is the best, so i want to know if the core i5 is beter, worse or if both are similar.

thanks

Hello and welcome to the forums
i5 is a faster and better choice.

Here is a site that has some useful stuff on notebook cpu's and the i3 is a great little performer that you might like to look at.

Remember the 35 watt TDP includes the CPU and Graphics ... as both are on the one die.

Hope this helps - check the other processor comparisons on that site ... I found it quite useful.

Hope this helps.

It's amazing how much misinformation floods people about computers. I have friends that still thought Pentium 4 was the fastest until I showed them the light.

The i5 is brand new, and significantly faster than the Core 2 duo.

the 32nm i5, which is only a dual core, would out perform a core2duo even if you disabled one of the two cores.

Mmm I'd say you may be pushing it a little far with that one. Lots of things are dual core optimized well enough to have more 1 core bring a hefty increase in performance.

I was aiming more for that the 32nm i5 has HT enabled, so it still shows as 4 cpus, and the 2 logical cpus on 1 core would probably out perform the old core2duo with 2 physical cores.

OK, thanks a lot

Even that is questionable, as 2 real cores scale much better than 1 real core with HT.
