Analysts don't think Apple's failure to meet its self-imposed 3GHz G5 target within a year is the company's fault, according to MacCentral.
JupiterResearch analyst Michael Gartenberg said: "That's always the danger in making technology claims like that. You just have to hope that the laws of the universe can keep up with your claims. I don't think it's that big a deal that they didn't hit that particular benchmark. I don't think we are going to see any Apple execs promise a particular speed anytime in the near future."
Analysts agree that the 90-nanometer manufacturing technology the semiconductor industry is moving to has caused the delay.
Aberdeen Research Group executive vice president and chief research officer Peter Kastner said: "In switching to 90 nanometers, the industry has had more problems raising the clock speed than anyone anticipated a year ago.
"Intel, for example, has only cranked up a couple of hundred megahertz from 3.2GHz to 3.4GHz. IBM gets an 'A' for the second quarter for being able to crank the chip up from 2GHz to 2.5GHz that's a 25 per cent increase."
Kastner doesn't expect the industry to reach the 3GHz target for another year.
Analysts main concern is whether IBM can make enough G5 chips to meet demand. Technology Business Research senior analyst Tim Deal said: "I question IBM's ability to meet Apple's increased G5 processor demand moving forward given the company's availability challenges to date," referring to delays in shipping speed-enhanced G5s after the model was launched last July.
