Intel Corp., working to regain its edge in processor technology, lost more ground to rival Advanced Micro Devices Inc. in the lucrative server-chip industry during the fourth quarter but took back some market share in personal computers.
Altogether, AMD reached a record high of 25.6% share in processors in the period, including custom chips for game consoles and semiconductors for the so-called Internet of Things, according to Mercury Research. That surpassed a previous high of 25.3% set in 2006.
