<If the higher die size is true, then the solution was to increase line size/spacing and add some heat diffusion space into the "fireball" core.> You mean they had to build a firewall around the fireball? They may have also added more Trace Cache to battle pathetic IPC numbers. Kap

Extrapolating the power consumption for 1.3 GHz and 1.4 GHz Willys to 1.5 GHz gives an estimated power consumption of 71.4 watts. By comparison, the 1.1 GHz Athlon uses 55.1 watts maximum thermal power and the CuMine 1.13 GHz uses 35.5 watts max thermal power. Petz

Eric, re:<Talking about hotspots!> Getta load of this spec for the P3 1.13 GHz, which I found perusing the latest Intel datasheet: CPU_Frequency maximum power density in watts per cm2 P3-800EB...32.6 P3-850.......35.2 P3-866.......35.9 P3-933.......39.9 P3-1000.....45.5 (old version) P3-1000.....40.9 P3-1133.....55.5 The spec sheet also makes clear that the P3-1133 may not have a junction temperature greater than 62degC, and that there is a 5.2 degC temperature rise from the case to the junction. This last number is also worse for the 1133 than for the 1000 by 1.4 degC. So the heat sink has to be able to dissipate 35.5 watts from an area 0.8 cm on a side, keeping the case of the P3-1133 at less than 56.8 degC inside a computer case where the ambient temperature is about 40 degC. Somehow I don't think we'll be seeing too many P3-1133 systems anytime soon. EDIT - a good question to ask is, Why is the active thermal area so much smaller for a P3-1133 than for a P3-1000 or anything else? Did they shrink the die that much and only get a 10% speed improvement? Petz
