Does duo core really, really mean 2?

Does a 2.2 duo core 2 intel processor mean it's the same as a core solo 4.4 processor? (if they existed)

 

No it is like what it says, two 2.2Ghz. In some instances it can do the same amount of work as 4.4 but it is not the same.

 

If the work can be shared equally between the two CPUs then your theory is correct.

However, if a program is single-threaded (ie is executed in one sequence) then one core will run the program and leave the other core idle (but available to run other programs and tasks).

Do two cars go twice as fast as one?

If possible (if the passenger/cargo load is suitable, they can transport twice as much per hour. But if you only have one passenger, it doesn't make a difference.)

 

Unless of course, the road is multi-threaded. Then the cars start flying.

Edit: Sorry, I'm going back to my hole now.

 

great analogy.

 

They do If they are traveling in the same direction and you add their velocities. However if they are going in opposite directions you have a total speed of 0. eg. There is twice as much energy in a colission between two cars going 60KM/h head on than with one car going 60KM/h hitting a wall .


Also you can go further with two cars. Just like you get better battery life from a dual core than you would a 4.4Ghz solo. eg. with two cars full of petrol you can drive them both till they are both down to half. Syphon the etrol from one car to the other so now 1 has a full tank again & the other im empty thus you get 1.5x the distance. Same sorta thing with laptop becasue 1 core is idle alot of the time you use less power so the core doing your work can do it for longer :s.


Sorry I'll be quiet now :s.

 

sorry to be so nit-picky, but i can't stand it when people call it "duo core". The technology is dual-core, and the brand from intel is core duo (with the more recent iteration "core 2 duo")

 

No it means there are 2 2.2GHz cpus running at the same time. Their speed does not combine, they just each do their own thing at the given 2.2GHz speed.

 

Haha!!!

 

agreed.

 

Yea I agree but like this one better. A tractor plows a field at 4.4mph, two tractors at 2.2mph can plow the feild in the same amount of time but if only one tractor is used half as fast. ( So totally stolen from another NBR member, don't remember who, sorry.) And the tractor going 2.2mph will never go 4.4mph.

 

Unless you overclock it!

 

Or it's going down a very steep slope!

 

why will it never got 4.4mph? We run Steiger (Case IH) 9390's at work and never run them at full speed when seeding/cultivating, always a little headroom left for when you have to pull up a hill

 

you guys....

 

You could always just average the speeds of the cores. That'll give you a pretty good estimate.

 

only in limited instances ie when the task to be accomplished can be executed fully in parallel. one example maybe applying a certain photo-shop filter to a certain number of images; if you have enough memory you can distribute the images between the processors and get all filtering done as if you have one processor running at twice the speed. but this completely depends on the task at hand and also the design of the application.

 

Blame intel's marketing of the Centrino Duo (generation b4 C2duo and Saint Rose)

 

Umm... Santa Rosa is still Centrino Duo. As is the Napa (Core 2 Duo/Core Duo).

 

Again, blame Intel's marketing for naming everything the same. Not even a number to separate the generations.
