TiBOOK: L3 or L2????

[sphereboy]

I was on the apple web page again staring at the TiBook waiting for mine to arrive while I noticed something strange:

It says in the specs when you click on BUY:

800MHz PowerPC G4
1MB L3 & 256K L2 cache

Why does it say 1MB L3 "AND" 256K L2 cache?

Why are there two cache thingies??

well one is 1MB and the other is 512k. if there are 2 caches it will be alot better.

sorry, i don't really know what the caches are for. of the limited amount of info i know about caches, here is what i can tell you: i think that the caches store data that is coming from the processer to RAM and/or visa versa. i'm not really sure about any of this but i think that when one cache is full the data goes to the next cache.
i'm not sure about this either, but i think that the caches are refreshed at every clock cycle. hope this helped.

here's a good site to have a look at if you're wondering about hardware and how a computer works in general: Ars Technica
sorry i didn't have time to check if they had anythng on caches, but you should find something interesting there.

Yuck...I would not want to explore a web page with a title: "A PC Enthusiast's Resource".

As for previous discussion of the L# cache (and maybe the L2):

That should work fine.

To correct myself, I meant L3 cache. That dang shift key...

You know, this reminds me of an article for why PCs runs slowly. If I am not mistaken, I think that because PCs have such a small L1 cache (maybe only 8k) small chunks of data can be carried about the computer. I do not have that source on me at the moment. I know that it is a very long web page.
