This one is slightly fast, but not obscenely though. We're coming up on a year since the last high-end server chips were released by Intel. So by the time the Ivy Bridge actually releases, we'll be hovering around the 18-month mark. The largest "problem" with their tick-tock method at this point is that it hasn't turned into the pure new architecture/die-shrink originally envisioned. Only some product lines get the die-shrink, others the architecture change. So we end up with chips being sold that use older tech, both in the high and low ends.
Just seems like things are moving fast because they're constantly bringing new things in place, but each CPU lasts in the market about as long as they did originally.
