Quad Core vs Dual Core how wud u say about this? uhmm ask lang q kung kinsay mga expert dha to explain a little or maybe long ideas about the usage of Quad Core vs Dual Core how it works in distribution of Data works and performance, why we should prefer quad core or why we prefer dual core?

Okay...i have a little knowledge about this but i need more info from the expert a clean explanation i read some forums but not enought for my satisfaction hehehe

Understanding the CPU: Fast food analogy

Most computer-literate people know that the CPU or the central processing unit is the most important part of a computer. It is the “brain” of the computer but do you know how each CPU element contribute to the processing power?

To explain the different CPU elements, here is a loose “fast food restaurant” analogy to help you better understand the CPU which can be useful if a salesperson tries to talk you into buying a PC that doesn’t match your needs.

Ok let’s take for example the Intel Core 2 Duo P7350, it has the following specs:

2 cores
2 GHz Clock Speed
1066 MHz Front Side Bus
3 MB L2 Cache
So how will you understand what those specs can do for you and your computer? Imagine you’re in a typical fast food restaurant…

Core



Think of the CPU core as a cash register. You can only pay for your meal to a cashier manning a cash register. In our example, the processor has 2 cores so it means it can handle more customers at a time. So imagine what a quad core can do.


Clock Speed



Think of the clock speed as the seniority level of the cashier manning the cash register. Lower clock speed means the cashier is not that familiar with the cash register so processing is much slower.

Question, is one cash register with a senior cashier better than two cash registers manned by trainees? Not always, two cash registers are still better especially when there are lots of customers (information to be processed).


Front Side Bus (FSB)



Don’t you hate it if the queue gets too crowded? You don’t know who’s falling in line and who’s just waiting for something and you’ll end up not falling in line at all?

The front side bus is like the cashier lane. The higher the FSB, the wider the lane so customers can get processed much better in an orderly manner.


L2 Cache



In your typical McDonald’s or Burger King, there’s this warmer located behind the cashier where they place burgers and other food so they can be served quickly. This is the L2 Cache.

A smaller warmer can only contain few burgers so if food runs out, the customer has to wait for a while before the kitchen can prepare a new batch.

Now there are some Intel technology that can also help the CPU. Examples would be Hyper-Threading technology and Turbo-Boost technology which is popular in the Core i3, i5 and i7 family.


Hyper-Threading Technology



In our fast food analogy, hyper-threading allows each of our cash register to have an additional queue allowing more information to be served without downtime.

If you have a dual core with hyper-threading, essentially you can serve 4 queues making it a psuedo-quad core. Of course, a dedicated cash register for each queue is still better.


Turbo-Boost Technology



Don’t you like it when you fall in line and there’s a cashier and another crew helping out in preparing for your food? That’s what Turbo-Boost Technology does.

Even if your cashier is not that experienced (low clock speed), if the other cashier doesn’t have any customer, he can turn into a helper and (turbo-boost) prepare the food for the other cash register. Say for example, there’s only one customer at the store but he wants to order in bulk. Turbo-boost ensures that processing is always optimized.

There you have it. If you’re stuck in deciding between two CPU’s, check its specific details and I hope this guide will help you make a smarter choice based on your needs.

i think you understand now if you will compare this to a quad core then?

Wew this is good to read thanks Master hehehe

gi hungit na mani boss.. hehe

[dude]

ahahha..good shot..

[dhekoy33]

kana ang saktong comparison,+1 kay sir siopao.

nakakat.on ko ug unxai Turbo Boost. smooth kaau pagkaexplain.
