  • cache

    just random question. i know having a big cache is good. but isn't it true the more the cpu has to search, the longer it takes? so is it better to have a big cache or a smaller one that the cpu can "look" throught faster?

    imo having a 256KB, 512KB or even 1MB of cache for that matter would never make your CPU slower. i mean simply thinking abt it, what would be slower...fetching data from RAM or from an on-die cache that a CPU has itself. if you would think on same grounds then 32MB RAM should be faster than 1GB one but then same thing comes here, fetching data from HD is slower. i hope more people will put more points :)

      I'm too lasy to type it all, so I'm just going to copy and paste what I said in another thread:
      cache is small amounts of super-fast memory on the cpu used to store commonly used insructions. The barton core doubles the amount of cache that the t-bred core used, thus theoretically speeding up the cpu by allowing faster access to more commonly used instructions. This can have a big effect in games since the same insructions are used over and over again.
      accessing data from the cache is much faster than anyting else available and the biggest reason it is not used as system RAM is the cost, the stuff is very expensive.

        Well would you rather have it search through the cache which runs at full speed (IE 3ghz processor, 3ghz cache) or have it run to the memory controller to search the RAM and then come back, all the while the memory is 5-10x slower?

        You can never have too much cache.

          Why do you think the 2mb cache chips are so much more than 256kb ones?
          Cache is like Mr.Fusion for your system!!!!!! :geek:
