Even if the PowerBook G5 was no faster than the PowerBook G4, people will buy it simply because it’s a G5.” Tim Cook, Apple’s VP of Worldwide Sales and Operations, continued the thought. “ It’s not about clock speed,” said Jonathan Ive, Apple’s design guru, “it’s about marketing. In the case of the 12″ PowerBook G5, they avoided heat issues by running a 2.0 GHz processor at 1.2 GHz.Ĭoupled with a 600 MHz memory bus – 3.6x as fast as the 167 MHz bus in current PowerBooks – and a broader memory path, the 64-bit CPU will generally outperform a G4 at the same clock speed.
Well, it was “the mother of all thermal challenges,” and Apple engineers knew there were several ways of dealing with CPU heat. The CPU is the most obvious difference – Baby Bear sports a PowerPC 970FX (G5) CPU in the same 1″ thin enclosure as current PowerBooks. Spec for spec, it matches the model announced on Monday in all but a few factors. The darling of the PowerBook G5 is the minuscule 12″ model, which is exactly the same size and weight as the current 1.5 GHz 12″ PowerBook G4. The PowerBook G5 will be available in three configurations, internally known as Baby Bear, Mamma Bear, and Papa Bear. “If the customers want it, we’re going to give it to them, no matter the technological challenges,” said Steve Jobs when demonstrating the new G5 models to the tech press. 2005 – Apple stunned analysts, Mac users, and PC pundits by pre-announcing the PowerBook G5 this morning – just two days after unveiling improved G4 PowerBooks.
