Nvidia demos quad-core Tegra chip at Computex

Tools

Nvidia (NASDAQ: NVDA) demonstrated a new four-core version of its Tegra family of processors at Computex in Taiwan on Monday. The company says the new chip will be on sale in tablet devices in September, with smartphones set to follow later in the year. Nvidia showed off the capabilities of the processor, code-named Kal-El, in a prototype tablet using a game from Madfinger.

The game consists of a ball illuminated from the inside, rolling around an arena sporting a carnival theme. Moved around by tilting the tablet, the ball casts shadows that are rendered in real time at a rate of more than 30 frames per second, while curtains at the edge of the playfield wave in an invisible wind, responding to the movement of the tablet. When Nvidia reduced it from four cores to two cores, the demo became jerky and unplayable, reports PC Mag.

Nvidia CEO Jen-Hsun Huang observed that "Kal-El will do everything the Tegra 2 can do but at lower power." All four cores in use should yield four to six hours on just a single charge, says Huang. You can watch the Nvidia demonstration on YouTube here. For now, competitors such as Qualcomm and Texas Instruments have also scheduled press conferences this week; Qualcomm had announced its quad-core Snapdragon chips in February.
