As if AMD wasn't already fighting an uphill battle, the market share slope just got a little steeper to climb. At the top sits Intel, who increased its market share of OEM PCs from 80 percent in August 2008 to 82 percent in December 2008, representing a 2 percent hike in just four months, says The Wall Street Journal.

To come up with the market share numbers, J.P. Morgan Securities uses a proprietary model which tracks semiconductor specifications at Dell and HP, the two largest OEMs, for notebooks, desktops, workstations, and servers. Because Lenovo-USA includes only corporate PCs, the OEM is excluded from the analysis. White boxes are also not included, which J.P. Morgan estimates accounts for 40 percent of the overall PC market.

As has typically been the case, Intel continues to dominate the processor landscape at Dell, increasing its market share from 95 percent in August to 97 percent in December of this year. The tug-of-war between Intel and AMD is a little more balanced at HP, with Intel increasing its share from 65 percent to 67 percent in the same time frame.

Intel's Atom processor has been a driving force in the chip wars, and for the first time appears in J.P. Morgan's survey. According to the report, the Atom chip accounts for 3 percent of the offerings from HP and Dell. AMD thus far has not made a push in the netbook/nettop market.

Now that AMD has split into separate design and manufacturing companies, do you see the chip maker's fortune changing in 2009? Hit the jump and post your prediction.
