is Dual core 2X faster?

Hi

I have a desktop PC which I'd like to replace with a laptop. Because I do mainly video processing I don't want less than the 2Ghz of CPU I have on my current PC. There are lots of dual core laptops around on the market. So my question is: does a 1.66 or 1.86Ghz dual core processor have more processing power than a single 2GHz?

Cheers.
 
The short answer: Yes.

They actually don't have double the power as some people think, but if the video editing program you are using supports dual core, it will undoubtedly be faster. If you use something like Adobe Premier, Ulead VideoStudio or Pinnacle Studio, you'll notice a much faster export/save process with dual core. The video codec you are using will also need to support dual core (for DivX and Xvid, this isn't a problem). If you're not going to use a codec, be prepared for massive file sizes, but superfast write speed (depending on RPM of the HDD). Do you have a laptop in mind, and if not, do you live in the USA? This will help people pick out a good laptop at reduced price for you.

For the same kind of money you will end up spending on the laptop, you could get a desktop editing PC about 5 times better. (Hinting the signature here). I use that system for all my video editing, and it is undoubtedly instant. Do you really need a portable station, or are you going to be happy with twice the performance, but being limited to editing at your desk?

The short answer for working with video as far video capturing/editing is no. The last build here saw a 2.2ghz single core cpu being replaced by a 3ghz dual core model in the current build.

Capturing/editing and burning dvds whether video or data saw a quick turn around due to a faster cpu plus having the work load lightened with a second core. Even Vista is loading faster to the desktop with programs installed over XP still at the basics. 2.4 evem 2.6ghz would be the starting point.
 
Is a dual core technically faster than a single core?
- No

Is it more efficient?
- Yes

How?
- I present you, the best dual core explanation in the world! ;)

...contrery to popular belief, if you have 2 cores, you will not have twice the speed, think of it as two 1 person cars. both are going 3 mph so both together are still going 3 mph, however since you have 2 cars, you get twice the about of people through in one go. so it is not faster, it can just do two things at once

That's all you need. :)
 
With a single and a dual sitting side by side with the same clock speed the performance gain with heavy loads is seen with the dual core cpu simply for not seeing the bottlenecks when extra demands are placed for cpu time. Faster here was going from 2.2ghz to 3ghz while adding a core saw items like the time involved in dvd burning was reduced drastically.
