larger amounts of cache seem to just go hand in hand with higher performance CPU's, eg, nobody has made a 3.6GHz cpu with 128kb L2 cache, nor have they made a 1.6GHz cpu with 2MB L2 cache. I think what im getting at is that there is no clear trend / difference with cache size vs performance and is to be considered as a part of the whole chip rather than a stand-alone memory module
