Intel posted record results on Tuesday that also cast doubt on claims of tablets hurting the market. Its revenue was up 25 percent to $12.8 billion and its net profit up by 29 percent to $3.3 billion. Most of that growth came from its datacenter chip team, whose revenue was up 32 percent, but it still saw its core PC chip group's revenue up by 17 percent as the second-generation Core (Sandy Bridge) take off.
