Pentium or Core processors?

The i5 has hyperthreading. You just need to get a laptop chip.

For desktops it works like this:
i3: 2 cores + hyperthreading.
i5: 4 cores. 4 real cores is better than the 2 cores + 2 "fake" cores the i3 gets from hyperthreading.
i7: 4 cores + hyperthreading.

yeah, you are right. thanks for your opinions and advice. i am just a little lazy and sometimes tired of reading those theoretical words. ;)

Pentium is 2 core
i3 is 2 core HT
i5 is 4 core
i7 is 4 core HT

Each step....pentium to i3, to i5 to i7 in general is a performance increase.

Why the i3 has 2 core and HT is that performance wise...its better to have 2 core with HT...than not (pentium) but its not as good as having 4 full blown cores (i5)

Yes moving from an i3 to an i5 you loose HT....but you gain 2 full blown CPU cores, which is better than the HT.






 
i just want to buy a new one. while before doing so, i chose this notebook cooling pad as a last resort. it seems much better now. i don't need to worry it can be hot enough to fry an egg. ;)
 
The problem with older chips in a laptop is that they're pushed to 100% just playing shockwave files on a website. In fact, the CPU is constantly running hot because it's almost or at its limit.

When I went from a 90nm fab chip to a 32nm fab chip, my laptop ran very cool. If you're surfing the web or watching movies, the chip can run at 20 watts TDP or so and the cooling system inside the laptop will easily remove that heat.

However, if you start doing heavy encoding or start playing games, even the newer chips will start to run hot inside of a laptop.
 
My laptop computer comes with dual-core Pentium processors and get hot seriously. i have a very limited knowledge about laptop property and i wonder whether one with Core processor dissipates less heat. is it closely related to Pentium or Core processors? which one is better?

Nope. It depends on the TDP for the processor in question AND the effectiveness of the thermal solution in place on your laptop. Some laptops overheat with a given CPU and some don't due to a more efficient cooling system and better chassis design (aluminum/magnesium dissipates heat).

Oh, i see. i have not noticed it before.

Flash will often use 100% of an entire core so you gotta be careful about flash wish single core machines. I've seen a animated stick figure use 100% of my cpu thanks Adobe just kidding.

The very reason that i3s *have* HTT is to make up for the lack of additional real cores. However, comparing an i3 (with HTT enabled) to a same-clocked i5 (no HTT) would be a disaster for the i3 - it would get waxed - even in applications that *support* HTT.

HTT is a compensator - nothing more.
