SAN FRANCISCO — Intel cracked the lid Tuesday on a new chip design that is at once a big challenge to smaller rival AMD and an admission that AMD nailed a key design feature before it slipped into a severe financial slump. Intel and chairman Craig Barrett (right) showed off the new blueprint for its chips at a developers conference. The design’s formal unveiling represented another demonstration of Intel’s advantage over AMD in cranking out new chip designs once every two years, a factor that helped send AMD’s stock price down 5 percent in an overall down day for technology shares. Intel now plans to build a part called an integrated memory controller — which moves information between the microprocessor and the computer’s memory — directly into the processor itself. AMD already incorporates integrated memory controllers into its processors. The Associated Press; Getty Images photo
