P4 forskel

ja... den kan gemme flere informationer, og dermed går det hurtigere...

ja altså den med 1mb Cache er hurtigere ;-)

hmm..  så enkelt er det ikke.
det afhænger af til hvad - den er kun hurtigere hvis det er de samme instruktioner der kan genbruges

Is more Cache always better? 

The answer is mostly yes but certainly not always. The main problem with having too much cache memory is that the CPU will always check the cache memory before the main system memory. Looking at our library again as an example. If 20 different people come into the library all after different books that haven't been taken out in quite a while but the library has been busy before and so the shelf and the bookcase are both full we have a problem. Each time a person asks for a book the librarian will check the shelf and then check the bookcase before realising that the book has to be in the main library. The librarian each time then trots off to get the book from the library. If this library had a non cache system it would actually be quicker in this instance because the librarian would go straight to the book in the main library instead of checking the shelf and the bookcase.

As the fact that non cache systems only work in certain circumstances and so in certain applications CPU's are definitely better with a decent amount of cache. Applications such as MPEG encoders are not good cache users because they have a constant stream of completely different data.

er det forklaring nok ?
i så fald vil jeg smide et svar :-)
