Apple recently threatened to drop Intel processors if power consumption in the latter's hardware didn't improve, Intel ultrabook director Greg Welch tells the Wall Street Journal. The information has emerged as part of an article on Intel's new $300 million Ultrabook Fund. The Apple ultimatum was made sometime before May, when Intel announced that it was planning to cut average power consumption from between 35 and 40W to just 15W. Lower draw is essential to ultrabook specifications.
