Maybe you wouldn't have some many people pissed at you if you defended your position with facts instead of name calling. If you know the real truth, please explain it, it shouldn't be hard for someone as knowledgable as you.
BTW, cache can help any processor as memory will always be slower and have higher latency than cache. And the pentium M and xeon have very good memory buses, the only thing in the consumer market that can beat them is the opteron's/athlon 64s low latency memory bus and it's a lot newer than the memory bus the pentium m and xeon use. And in the past the memory bus of the p4 destroyed the memory bus of the athlon xp(higher bandwidth and lower latency, plus p4's have much faster cache), yet the p4 needed more cache to be able to beat the athlon, so your excuse of a poor memory controller being the reason for more cache is definetely not the only reason to add cache.
