SAN FRANCISCO (Reuters) – ANALYSIS – Nvidia Corp’s decision to indefinitely postpone investment in chipsets for Intel Corp’s next-generation processors signals a shift in focus to fast-growing mobile devices that could see the company exiting the PC chipset market.

Led by Taiwan-born Chief Executive Jen-Hsun Huang, executives at the company that spends up to $1 billion annually on research have been talking up its Tegra mobile chip platform — which manages power, memory and graphics for devices such as Microsoft Corp’s Zune media player.
