By Noel Randewich LAS VEGAS (Reuters) – Chipmaker Nvidia Corp gave new details of an upcoming chip with beefed-up graphics for mobile gadgets and cars as it faces a slowing personal computer industry and harsh competition in smartphones and tablets. The K1 is Nvidias first mobile chip to incorporate the Kepler graphics technology the company uses in the high-end components it makes for PC game enthusiasts, Chief Executive Jen-Hsun Huang told reporters at an event in Las Vegas on Sunday ahead of the Consumer Electronics Show. Huang in recent years has expanded Nvidias business beyond its core PC market and into mobile devices with the companys Tegra lineup of chips. But he has encountered heavy competition from larger Qualcomm Inc and Samsung Electronics Co Ltd in making components for tablets and smartphones.
