Several Qualcomm (NASDAQ:QCOM) execs are knocking Microsoft's (NASDAQ:MSFT) new Surface 2 tablet. Qualcomm claims Nokia's Lumia 2520 Windows tablet outperforms the Surface 2 in several meaningful ways, including speed and power efficiency. Why would Qualcomm criticize the Microsoft Surface 2 tablet? Because it's running NVIDIA's (NASDAQ:NVDA) competing Tegra 4 chip.
