Nvidia will introduce its next-gen graphics processors for mobile computing at a visual computing conference this week.

The new graphics chip technology, dubbed Project Logan, is based on the company's Kepler architecture and proposes to bring workstation-class graphics to mobile computing.

"It brings a huge jump in performance [and] offers extraordinary power efficiency," Nvidia said in a statement.

That means about one-third the power consumption of graphics processing units (GPUs) in today's tablets, such as the iPad Retina, while delivering the same performance, Nvidia said.

The technology will be demoed this week at the Siggraph show in Anaheim, California.

To demonstrate the technology's capability, Nvidia is demoing "Ira" (see embedded video above), which it describes as a "startlingly realistic digital model of a human head generated in real time."

The same demo was done earlier this year at an Nvidia conference but it was running on a desktop PC equipped with a GeForce GTX Titan GPU, the company's most powerful single-GPU gaming processor. In this demo, it's running on the Kepler GPU inside Logan.

Nvidia will also use the technology in other mobile applications outside of graphics, including computational imaging, computer vision, augmented reality, and speech recognition.

Products with the Logan tech are expected in the first half of 2014.
