Re: looks like the new Intel 0.13 process has some problems: excessive leakage! Great job Ali! You've solved a big mystery. When PC magazine tested Compaq and Dell notebooks a few months ago, the 81mm2, .13 Pentium III-M 1.13GHZ Dell had battery life of only 2:35, while the 128mm2 .18 1GHZ Athlon4 had battery life of 2:59. The Dell had a slightly larger screen, and was clocked 10% faster, but had a more integrated motherboard which should have saved a watt or two. Notebook screens typically use 4 to 5 watts, hard drives use 2 to 3 watts, so the primary determinant of a notebook's battery life is the 20 to 30 watts the CPU uses. It was amazing that the little PIII, using Intel's vaunted .13 copper process was using as much (or more) power per MHZ compared to the (relatively) huge Athlon built on AMD's old .18 process. But now we know what was happening. pcmag.com pcmag.com And since then we've seen the specs on AMD's latest 1.2GHZ mobile Athlon - and it actually uses less power than the 1.1GHZ Athlon. HP's Athlon 4 lasted 3:19 while their PIII-M lasted 3:22. It's absolutely amazing, when PIII was on Aluminum .18, it used half the power of AMD's .18 copper Athlon - to be expected, since it was so much smaller. But on .13 copper, Intel's PIII uses nearly as much power as a much larger .18 Athlon - it's really something. No wonder why Jerry was gloating about AMD's advantage in mobile chips...
