SAN MATEO, Calif., August 2, 2011 – Worldwide PC microprocessor unit shipments in the second calendar quarter of 2011 (2Q11) declined 2.9% compared to 1Q11 and were about flat compared to 2Q10, rising 0.6%, according to the latest PC microprocessor market share study from International Data Corporation (IDC). On a revenue basis, the PC microprocessor market earned $9.49 billion, declining 4.0% compared to 1Q11 and rising 5.4% compared to 2Q10.
"The first quarter of 2011 was better than most first quarters due to the extra calendar week," said Shane Rau, director of Semiconductors: Personal Computing research at IDC. "So the sequential comparison isn't surprising. If we took off that extra week, the performance between the two quarters probably would've seen a seen a slight sequential uptick from 1Q to 2Q."
Both Intel and AMD continue to ramp their new platforms. Intel's Sandy Bridge and AMD's Fusion microprocessors contain integrated graphics processors (IGP). IDC's tracking of these processors indicates that processors with IGP rose to more than 60% of total PC processor unit volume in 2Q11.
