>P4 is still stuck with an 8-way cache, while Athlon has a 20-way cache. P4's cache is simple, but fast, which is apparently needed to keep bubbles out of that long pipeline.< Athlon has two-way set associative Harvard Architecture L1 caches and 16-way set associative L2 caches. With the exclusive architecture, the cache is effectively higher than 18-way, but less than 20-way. >With its limited set associativity, making the P4 cache much larger will be of limited use.< For most users, the improvement for going 16-way versus 8-way for 512KB and above is minimal. For the most part, only server class applications benefit significantly from associativity higher than 8-way at and above 512KB.
