This news is kind of old, but I thought I'd post it anyway, just in case.

Motorola: G5 microprocessors will hit speeds of 2GHz

G4 production problems or not, Motorola is already planning its next versions of PowerPC chips that will run on the Macintosh line -- and they'll be faster than expected, according to the company's "Power PC Microprocessor Strategy."
In fact, the G5 chip will scream at speeds of over to 2GHz if Motorola's predictions are on target. The microprocessor -- which should see the light of day by 2002 at the latest -- will come in 32-bit and 64-bit flavors, and so would sport the ability to "transparently" run present 32-bit applications. For the technically minded, the chip will have an extensible architecture, a new pipeline, new bus topology, and a 0.10 micron processor with SOI. The G5 is described as a "high performance microprocessor targeting computing and high-end embedded" markets.
Less is known about the G6, but it's on Motorola's roadmap. An arrival date of two to three years after the G5 rollout is feasible. Interestingly, the company plans to continue manufacturing the G3 and G4 chips along with the G5 and G6. In fact, the "Microprocessor Strategy" says G4 development should see it reach speeds of up to 1GHz.
Motorola: G5 chip will achieve 2 GHz

Want to know what Motorola's got up its sleeve for their next generation of Power PC processors? We thought you did.
According to a recently revived "Motorola PowerPC Microprocessor Strategy" document, The G5 will have an extensible architecture, new pipeline, and new bus topology. It will support 64 and 32 bit products with backward compatibility. The G5 will have a 0.10 micron manufacturing process that will integrate Silicon-On-Insulator (SOI) technology. How fast will it run? Up to 2 GHz, according to Motorola's document.
SOI has transistors sitting atop a glass layer instead of on traditional silicon. The use of glass prevents electrons that flow through a transistor from escaping, increasing efficiency and reducing power consumption. IBM, which also makes Power PC chips for the Mac, announced IBM announced the industry's first semiconductor manufacturing process combining silicon-on-insulator (SOI) and copper interconnects in August 1998. IBM's SOI technology alone can provide a 30 percent performance improvement.
IBM shipped the world's first production PowerPC-based microchips made of SOI transistors and copper wiring in May. These SOI-copper PowerPC processors power IBM AS/400e servers. IBM also has a new semiconductor manufacturing technique that shields millions of individual copper circuits on a chip, reducing electrical "crosstalk" between wires that can hinder chip performance and waste power. It's called low-k dielectric technology and was announced in April 2000.
Meanwhile, the current G4 chip still hasn't topped out. According to the "Motorola PowerPC Microprocessor Strategy" report, it should top out at speeds of up to 1GHz. The G4 will stay with AltiVec, get an on-die L2 cache, and move to a 0.15 micron copper manufacturing process that will eventually integrate SOI technology.
AltiVec is the PowerPC extension technology that Apple has branded as Velocity Engine. It dramatically accelerates certain multimedia functions.
There aren't, as far as we know, details on IBM's Power PC plans regarding SOI and AltiVec in regards to Mac systems. Still, Apple, IBM, and Motorola have long cooperated (and sometimes disagreed) on chip development. The three companies jointly developed the PowerPC chip. However, Motorola and IBM's new chip advances could positively influence the Mac market given the companies' past and current relationship with Apple.
Finally some definite proof of the G5's technology!
