NVIDIA (NASDAQ:NVDA) has just reported its latest earnings results, and investors were mostly pleased with the figures. The graphics segment continues to hold up well in the face of a difficult PC market, and NVIDIA also continues to diversify its business. Most of that diversification comes from its growing Tegra business, where it hopes to get its chips in smartphones, tablets, and eventually cars.

Tegra revenue has languished for most of this year as NVIDIA strategically delayed the Tegra 4 schedule to develop Tegra 4i. Tegra sales bounced back nicely last quarter, more than doubling sequentially to over $110 million. The Tegra 4i will be a milestone for NVIDIA, as its first chip with integrated LTE connectivity. That will be the first meaningful threat to Qualcomm (NASDAQ:QCOM), which has enjoyed its first-mover advantage. Tegra 4i has now been certified on AT&T and is set to launch early next year in consumer devices.
