Albert, thinking about it some more, I think just releasing a 900 MHz notebook chip on Thursday would get big headlines. Intel's max is now 850 MHz, and they have NEVER been behind in notebook MHz, AFAIK. I just looked at the spec sheet for the SpeedStep notebook chips. The 850 MHz consumes 20.1 amps at 1.6 volts = 32.2 watts maximum power. All this wattage must be dissipated inside the notebook, but the power dissipated in the chip itself is18.2 watts typical and27.5 watts maximum. I found looking at the spec sheet that the claim for less than 1 watt dissipation for the 500 MHz chip is totally bogus. First of all, it is based on assuming that the CPU spends 90% of its time in deep sleep mode and it only counts heat dissipated from the chip, not the total power consumption. While actually running at 500 MHz the chip consumes up to 8.7 watts, not counting the separate supply for the buffers which is something (unknown) between 0 and 3.7 watts. Even at 300 MHz, the first number is 4.6 watts. Intel has not caught up to TMTA by a long shot. Petz
