The 15-GHz


Gelsinger would not disclose whether he expected these speeds to be seen in Pentium 4 processors or those based around a new architecture. Intel has said previously that the current Pentium 4 architecture is good up to around 10 GHz

"We haven't been specific," he said at a post-keynote news conference. "You would look a major micro-architecture like the Pentium 4 and it is typically five to eight years

Going Mobile
In the wireless and PDA space, Gelsinger said, the company is expecting to see speeds rise from the current 400 MHz to 5 GHz

That period is longer than the four to five years Intel took moving its desktop processors through the same speed improvements, as there are power concerns that need to be taken into account in designing processors for wireless and handheld devices.
"Desktops today are [consuming power of] 75 to 100 watts

"Obviously, you are optimizing the design for different criteria. So today, if I was going to look at a StrongArm core or XScale core, could I create a 2-GHz or 3-GHz XScale today? Absolutely. Could I do so and deliver the best trade-off of power and performance inside a 1-watt envelope? No. You tend to design the chips differently to live inside different devices."
