Advanced Micro Devices (AMD) is set to launch its Llano APU in Q3 of 2011 to compete with Intel's (INTC) Sandy Bridge. Here we take a look at how these two processors stack up against each other. AMD also competes with Nvidia (NVDA) in the PC microprocessor and graphics businesses.

Our price estimate for AMD stands at $8.85, which is roughly in line with market price.

Advanced Micro Devices (AMD) mainly competes with Intel Corporation (INTC) in the server processor market. By our estimates, server processors constitute around 20% of AMD's stock price.

AMD's market share in server processors was at its peak in 2006, at around 25%, driven by the success of its Opteron series of processors. But very soon Intel regained its lost share by introducing the Xeon processor and releasing upgrades and newer products in the following years. AMD's loss was compounded when it was late in its launch of the Barcelona chip in 2008.

Advanced Micro Devices (AMD) competes with Intel (INTC) and Nvidia (NVDA) in the PC microprocessor and graphics businesses. Our price estimate for AMD stands at $9.30, which is roughly in line with market price. We estimate that although most of the company's value comes from microprocessor business, about 14% can be attributed to graphics.

One of the recent wins in this regard was Apple's (AAPL) plan to use AMD's graphics cards in its Macbook Pro notebooks. What does this tell us about AMD?

Advanced Micro Devices (AMD - option chain) stock is trading lower today after the company announced the resignation of CEO Dirk Meyer, naming Thomas Seifert interim CEO. Investors are surprised by this announcement, since Meyer took over AMD when the company was floundering and has since stabilized AMD. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on AMD.

For years Microsoft (MSFT) was the tech leader. Then, Google (GOOG) came along and Microsoft missed the entire search engine revolution. But Microsoft still dominated in software. Then came Apple (AAPL) with its iPod, iPhone, and iPad. Again, Microsoft missed the small device revolution.

The Wall Street Journal reports that now Microsoft is playing catch-up again. With its next operating system it will use low-powered chips similar to those Apple uses.

Call volume is unusually heavy on Advanced Micro Devices (AMD) today, with nearly 8,300 contracts changing hands during the first hour of the session -- easily outpacing the stock's average daily call activity of 6,774 contracts. However, the day's option volume isn't necessarily bullish in nature.

Nearly all of today's volume has taken place at AMD's January 2012 7.50 call, where a block of 8,000 contracts traded at the bid price -- suggesting they were most likely sold. This block appears to have been tied to a corresponding stock trade, which means we're likely seeing the initiation of a buy-write position.

Advanced Micro Devices (AMD) is scheduled to take its turn in the earnings confessional after Thursday's close, with analysts looking for a third-quarter profit of 6 cents per share on $1.67 billion in sales. AMD swallowed a loss of 18 cents per share in the year-ago quarter, leaving plenty of room for improvement.

The semiconductor company has a solid history on the earnings front, having surpassed analysts' per-share profit expectations in each of the past four quarters. However, traders don't seem convinced that AMD can manage another upside surprise.

The earnings season kicked off last week with better-than-expected results from Alcoa (AA) and Yum! Brands (YUM), while Marriott (MAR) and Pepsico (PEP) met consensus EPS estimates. This week, bellwether companies Intel (INTC), General Electric (GE), Google (GOOG) and JPMorgan Chase (JPM) are scheduled to report their third-quarter results, and analysts polled by Thomson Reuters are looking for earnings growth from all of them.

Santa Clara, Calif.-based Intel announced the acquisition of McAfee and joint ventures with General Electric and Nokia (NOK) during its third quarter. Analysts forecast earnings for that period to come to 50 cents per share, which is up 34.0% from the same period of last year. The number one semiconductor maker's revenue for the three months ended in September is expected to total $11.0 billion, or 17.1% more than a year earlier. Looking ahead to the full year, the forecast thus far is for earnings of $1.94 per share (+44.8%) and $43.3 billion in revenue (+23.4%). The per-share earnings topped analysts' expectations in the past four quarters, by as much as a dime per share.
