1processor with 4cores i need more explanation ani daw atong mga techi dha

---

As what i've read on Wikipedia a processor can only have 1 core, but im just curious on my new imac specs i5 which is 1processor with 4cores can anybody have technicality on how it is? i need more explanation about this at least i have and idea.

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.

Yes i read this before but my concern is akong imac is 1processor but upat ka core as wat i read on this link Multi-core processor - Wikipedia, the free encyclopedia 1processor is composed of one core if dual core it should be 2processor but that link explain i think the first creation on processor nag wonder lang q, kung unsa ang technical term or way of understanding for 1processor but 4cores

maybe its 4 cores fit into 1 processor, as what you said, 1 proc = 1 core man unta diba?

just my guess lng... cant really explain in technical detail

[CrasHBURN]

TS, according to your link... FIRST LINE says:

"A multi-core processor is a single computing component with two or more independent actual processors (called "cores"), which are the units that read and execute program instructions."

I don't see why you are confused with what you are reading... Basically, you answered your own question.

[CrasHBURN]

An Intel Core i5 is a single processor with FOUR CORES in it. It is called a Quad Core processor. Runs like a computer with 4 processors.

from my understanding, CPU=processor.

if you see server-type processors they usually have 2 CPU (or processors) like xeon processors and some SB-E utilizes 2 CPU(processors). now what does core mean? it means the number of processors within that single chip. dont confuse yourself, the chip as a whole is a CPU/processor, the number of processors within that chip are called cores and the chip as a whole is a processor.

Tumpak bro will said master hahaha actually i found my answer na but i just wanna know wat others point of view to xplain it here hehehe
