The lower end model has gone from 700Mhz to 800Mhz. That is fine, not every revision of the product line has to be ground breaking. The L2 Cache is 256. Those who know more about this let me know. My G4 350 has 1Mb of L2 Cache. Only for the lowest end model. The next one has 2MB of level 3 cache.

As Alomex stated, the higher end machines use 2MB L3 cache. Note, however that the L2 cache (256kB) is on-chip and runs at full processor speed. The L3 is off-chip and runs slower at about the same ratio of clock speed as does your older G4's 1MB of L2 cache. So the new L2 runs much faster but empties much faster also. Without L3, the processor will run very fast into cache reloading stall periods - giving a kind of jerky feel to the software. L3 will make the stall periods much less noticeable. Windows people have more noticeable stall periods because it takes a lot longer to reload the pipelines after a cache miss.
