Currently nvidia Tegra 2 processor only meets the requirements, and has also been made the reference design for Honeycomb. These statements are coming from managing director of Korean electronics form Enspert, which launched an Android tablet for telecom operator KT last year.
While, I do not want these rumors to be true, there seems a significant truth in these. We have already heard the Tegra 2 is reference design in a separate leak, all the leaked tablet plans with Android 2.4 on-board also have Tegra 2 in them.
But do not worry, chip market is already waiting to explode with dual core processors everywhere from Qualcomm to Mediatak and other companies, with significant price drop in sight.
