Kevin, Is it because with 64k of L1, you need to have 4x as much L2 to really see a performance improvement? That is correct. The memory hierarchy from L1-L2-L3 has to show an steep increase in size at each stage to be of any benefit. Mendocino showed a large performance improvement because it went from 32K L1/0K L2 to 32K L1/128K L2. In contrast, K6-2 systems typically have 1MB (slow) L2 on them already. Scumbria

Kevin - Re: " But also keep in mind that the Sharptooth has more transistors than your Dixon," The only significant difference is in the L1 cache size/transistors - 32K Bytes for DIXON and 64 K for the late-to-the-party Sharpy ! Re: " Maybe that's why it is appearing one month after Dixon?" Dixon has APPEARED INSIDE MANy, MANY NOTEBOOK COMPUTERS - ready for sale. Sharpy will be launched this quarter - but how many companies will have Sharpy products ready for sale? One? Zero? That's a HOLLOW launch ! Paul
