Chip behemoth Intel still rules the waves in microprocessor shipments.

The Santa Clara outfit has silicon in 79.7% of the overall PC market, 86.5% of notebooks and 86.2% of workstations, according to IDC. AMD has 19.7%, 12.6% and 13.8% respectively.

Overall, the PC processor business grew 3.1% in unit shipments in the three months to June, but price competition drove revenues down 4.5%.

IDC reports that Intel unit shipments were up 4.3% on the quarter and almost 21% year-on-year, while AMD remained largely flat. IDC reckons CPU sales for 2008 will grow by 7.5% to around $32.8 billion. 

AMD has been losing market share to Intel since the third quarter of 2007 when it had 23.5% of the market, but the smaller company posted a modest 0.8% improvement in the lucrative workstation market.

The only other chipmonger showing on the IDC radar was Taiwan's Via, rising 0.7% to just shy of one percent of the notebook market. X
