Jim, How much more speed will the Thunderbird have when it puts the L2 on die? If you're not sure how much L2 on die, use 256k and 512k. By speed, I assume that you are talking about architectural performance. The L2 cache on Thunderbird actually may have the effect of slowing the clock speed down. It is entirely possible that the MHz advantage that Athlon currently has over PIII may be due to the full speed L2 on Coppermine. Anyway, I'm guessing that the Thunderbird cache will be a small victim cache, and will increase architectural performance by about 5-15%. It remains to be seen if the onboard L2 cache was a good idea. In fact, we may never know.... Scumbria
