Quad Core vs Dual Core how wud u say about this?

wew ^^ nice brO..

how wud u say on this there are two Cache label on a computer which one is running? L2 or L3? and yes wat about RAM?

Processor Name: Intel Core i5
Processor Speed: 3.1 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 8 GB

if L2 Cache is this warmer located behind the cashier where they place burgers and other food so they can be served quickly
(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.)

the L3 Cache would be the kitchen staff. the more the kitchen staff, the faster and more food will be prepared to store it to the warmer so that it it would not run out of supply for the next customers.

Wow!!!thanks for the explanation now i know wat is the usage of L3 hmm but is okay for this specs that L2 is only 256 KB? what is that mean when it says L2 Cache (per Core): 256kb? is it the 2mb are distributed to the four cores in the processors?

another analogy na lang for the memory TS

RAM is like our brain, we could only remember so much at any one time. If you wanted to remember other things, you could write them down in a book and put that book on a shelf. In this case, the shelf is the hard drive. To remember that thing, you would need to go to the shelf and read the book, which takes much longer than just recalling it.

If that is a quad core processor then it has has 4 cores -- it is like the one processor has 4 engines inside of it and each one has its own cache.

It is not necessarily the case that having more cache is always best.

In computer design, the goal is to be efficient. A smaller cache works better when you are dealing with smaller amounts of data. The operating system, for example, would not need a very large cache.

You only want the cache that is appropriate to the job.

For example, if you had a much bigger suitcase than you needed for a trip, would that be better? You'd rather have the suitcase that was just the right size.




Cache's are memory (RAM) that can be directly accessed by the processor without the need for going through the computer's memory bus or OS, thus the processor has faster access to it. The cache is used as a temporary storage place for (sometimes) the next anticipated data from a file. I seem to recall that processors can also store the temporary results of a series of calculations in the cache - but maybe I'm confusing that with something else? At any rate, the larger the cache, the more temporary data that can be stored and accessed directly by the processor, thus it speeds up the process.

wew this very clear explanation thanks Master Siopao murag mi set in sad q sa school ani ug 2units dah hehehe clear and understandable kau hehehe

Memory mao nay storage sa mga ge.process nga file sa processor. so kung gamay raka ug RAM mao nang maghang-hang. the more RAM the more space nga ma storan sa mga files kung magprocess na

nice analogy. ayos na ayos

[KH0UJ]

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

Very well said MASTER!!!!
