Before Steve Job’s took the stage at last week’s WDDC, Apple’s problem was that for four years its processor upgrades have fallen short of Moore’s Law. Now everything’s changed.
“The G5 is revolutionary: a 64-bit machine running, at its heart, a variant of Unix, able to use up to 8Gb of RAM and address up to 18 exabytes (18,000 billion gigabytes) of disk space. It whirls data about on a processor bus running at 1 Ghz – faster than that on Intel machines now, which run at up to 800Mhz. And it is very fast when you’re in the driving seat – applications start so quickly that you feel like the weak link in the chain as you dither over the keys. Intel, meanwhile, insists it will stick with 32-bit machines; the move to 64-bit will be painful for Windows users, and seems to be years away,” reports Charles Arthur for The Independent UK.
Arthur continues, “Meanwhile, many Mac fans lapping up the details of the G5s are asking: how soon can we get a G5 laptop? Apple executives were guarded about this last week, because the chips are so hot: the G4 consumes about 41 watts in a desktop; the G5, nearer 80 watts. That means shorter battery life and a hotter lap. Rely on Moore’s Law to shrink the size, and hence power consumption and output, of the circuits enough to make a laptop feasible. When? “Not any time soon,” said one Apple executive last week. A quick calculation suggests that six months would be a reasonable period – now that Apple is once more obeying the laws of computing.”
