1. The extremely large amount of cache will not really affect m/cs with small number of processes, as a small amount of cache is usually anough for a very high rate of hits. After that the latency issues arise, which can be taken care of by aggressive pre-fetching.
2. It will make a major difference when there are a large number of processes... prevents thrashing...only between the L1/L2 cache and the memory....as must be obvious...HP is targetting Servers with that processor.....where in a large difference can be expected....For single user workstations...an 8MB L2 cache is more than what you will ever ever need.
