SUPER challenge...please answer some questions I have about CPUs

post #1 of 29
Thread Starter 
*Not sure where to put this...mods move as needed*

*WARNING* The following content may not be suitable for people with quick tempers, or people who can't stand constant confusion from the learnee.

I would like for someone(s) to explain in the simplest terms possible answers to these questions:

My first question about processors is, how virtually and physically ops/cycle works.

Second question is, how in the world to processors take info from hdds and put it into what we see on the screen (please use as much detail as possible), also how is ram incorporated into that.

What is the roll of ram, and how does it work? (please use max amount of detail possible).

What are a CPU's main internal components, and how do they all function together?

What does 65nm cpu mean?

-You can expect much confusion, and many question.

-Also, anyone(s) who explains 1 or all of the questions to me will be considered the bravest person on oc.net And will be fully reimbursed for their time *cough*rep*cough*

P.S. I am a visual learner, so if you could explain things to me using real life examples, or pictures I would greatly appreciate that.

A 65nm CPU is just the process that it's made with. It means that most of the gates are 65nm.

You're going to have to do better than that Remember..I am stupid. What the heck are gates, what are processes.

...I am going to put a warning sign

the ops (operations per second) play a big role here a amd does 9 ops per cycle and an pentium 4, 6 so it needs an higher clock speed to get the same amount of work done so an 4000+ puts down the same amount of work as an 4 ghz pentium 4 only on 2.4 ghz....but correct me if im wrong

Ops/cycle is how many operations per cycle (hz) the particular processor does.

For instance, a typical AMD Athlon 64 processor does 9 ops/cycle. Meaning for every cycle, 9 things(operations) have been calculated. Think of it as RPM on an automotive engine. RMP is revolutions per minuit. Revolutions being ops and minuit being cycle.The higher the RPM, the faster the engine spins... So the higher this ratio (ops/cycle) is, the more the processor can do for a givin speed, which is measured in hertz (cycles).

Intel pentium chips perform 6 ops/cycle. This explains why an AMD @ 2.2 ghz is faster and outperforms the intel that is clocked at 3ghz. Though ops/cycle isnt the only judging factor for a cpu...



Sorry if this doesnt make sence... had a few too many drinks...

Yep, and Conroes do 12.

RAM just holds the stuff thats going to be used soon, so when its time for that piece of data to be used, it will just pop up quicker instead of having the HD search and load that file right before it needs to be used. Thats why games with big maps, textures, and other stuff use alot of RAM.

Great...I love that explanation. Now, what is it physically on an AMD cpu that makes it have 9ops/cycle as opposed to intels 6?

So ram is just basically like flash memory?
