G5 Macs Around the Corner?

Sources Say Macworld 2002 Will Be a Big Day For Apple By Charlie White
G5 Around the Corner?With the buzz about the newest chips for Macs reaching a fever pitch, Mac watchers around the world are busy speculating about what will happen at the next Macworld Expo, to be held in January 2002. Since Macworld Paris was cancelled because of the terrorist attacks in the US, speculation on the new Macs has reached an even higher level in the past few weeks.

Closing the "Megahertz Gap"?
The possibility of new chips that will close the so-called "megahertz gap" along with a new 64-bit release of Mac OS X makes the word "revolutionary" seem not quite so far-fetched. But keep in mind, that the following information is not provided or endorsed by Apple or Motorola, both of which have been working on the new chips and software for years and want to make a big splash when they are introduced. In this report, we take a look at the latest information, gleaned from published reports and reliable industry sources.


The newest chip in Motorolas arsenal, code named G5, is said to be officially named the PowerPC 8500. Early speculation on the chip had its name to be the 7500, but now its been dubbed the 8500. According to sources, the desktop models of the chips will run at 1.2GHz, 1.4GHz, and 1.6GHz., and are said to contain 58 million transistors, more than twice that of the G4.

More Good News
More good news is that the new G5 will support multiprocessing, and will be a 64 bit chip, while still remaining compatible with 32-bit applications and running them at full speed. This is unlike Intels Itanium 64 bit chips which contain an emulator to run 32 bit applications. Another benefit of this new G5 technology is the quicker, 400 MHz front-side bus, along with standard DDR SDRAM memory chips. And, running underneath these new chips will be a motherboard chipset designed for the G5, which will allow Macs to support up to 16GB of RAM.

Other niceties of the new system will be its USB 2.0 support, which runs at 480 Mbps compared to the measly 12Mbps of USB 1.1. FireWire will also reportedly be ratcheted up to the current 1394b spec, transferring data at a blazing 800Mbps compared to 1394s 400Mbps.

OS X Update, Too
Expected at about the same time (in time for Macworld) is the newest update of OS X, version 10.2. This upgrade will bring 64 bit processing to the Mac , but its unclear so far whether applications will need to be re-written for 64 bit operation, or if a simple recompile will suffice.

The new chips are undoubtedly headed for the newest Macs, but will probably be introduced before Macworld in January. Some sources have the introduction of Motorolas newest processors happening at the Microprocessor Forum on October 15th in San Jose, California.
