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.
