No, the G4 is the successor to the 604e, NOT the 603e. The G4 is nothing more than a G3 with slightly improved FPU and the Altivec extensions.

As the differences between the bleeding edge desktop market and where PowerPC is heading become more and more evident Apple either has to start building products that look less like desktop PCs and more like internet appliances and PDAs etc or chose a new processor family. It is there to win sockets in future generations of base stations for wireless services. Mot didn't build Altivec into G4 for Steve Jobs ego.

Neither Mot nor IBM want to pretend to compete with Intel for the desktop any more (although IBM is doing some interesting 64 bit Power chips such as Northstar and Pulsar that compete against Xeon in the server market). I should bloody well hope so - the Alpha EV68 and AMD K7 will likely exceed 1.5 GHz in a 0.18 um aluminum process The writing is on the wall for Apple.

The roadmap shows the G4 hitting 1 GHz in a 0.15 um copper process. It has ridiculously short pipelines and rather modest out of order execution resources. But PowerPC hasn't kept pace with microarchitecture developments in the x86 world let alone with its RISC brethren. The G4 is a slick chip for high end embedded control and digital signal processing.

The PPC 750 (G3, or Arthur) is a glorified 603e tweaked to run Mac code better. The PowerPC family hasn't been maintained as a general purpose desktop and server RISC ever since the Somerset joint design center blew it keeping the 604 on the performance curve and wiffed on the 620. It might also be noteworthy to know that a lot of cases today probably won't shield well against frequencies above 1 GHz so you might start having problems with phones, radios and the like. Most adverse health effects that could occur from exposure to RF fields between 1 MHz and 10 GHz are consistent with responses to induced heating, resulting in rises in tissue or body temperatures higher than 1C.Īnyhow, for more information visit the WTO EMF web site.Such energies are found tens of meters away from powerful FM antennas at the top of high towers, which makes these areas inaccessible. An SAR of at least 4 W/kg is needed to produce adverse health effects in people exposed to RF fields in this frequency range.The depth of pentration of the RF field into the tissue depends on the frequency of the field and is greater for lower frequencies. RF fields between 1 MHz and 10 GHz penetrate exposed tissues and produce heating due to energy absorption in these tissues.Current exposure standards preclude human presence in this areas. They do exist in very close proximity to powerful radars. Such densities are not found in everyday life.

For adverse health effects, such as eye cataracts and skin burns, to occur from exposure to RF fields above 10 GHz, power densities above 1000 W/m2 are needed.

RF Fields above 10 GHz are absorbed at the skin surface, with very little of the energy penetrating into the underlying tissues.

There are studies on metabolic, reproductive, and neurological changes associated with low intensity EMR.Īnyway, here are a few facts from the WTO study on EMF: From what I understand, prolonged exposure to low wattage microwaves can be damanging to exposed soft tissues in your body (such as eyes), but the output of a CPU probably won't do it.
