Filed under: DesktopsIt's Fall IDF time in San Francisco, and Intel really came out swinging in the chips department. The company is releasing 15 of its new 45nm Penryn this year, with the first chips hitting on November 12th, and another 20 hitting in Q1 2008. That could get some of those chips into desktops before AMD's 65nm Phenom hits, and is earlier than was expected from the chip giant. The Penryn chips are promised to bring a 20 percent performance increase while improving energy efficiency. Intel also took the opportunity to show off Nehalem, Penryn's followup.
