Microsoft's Zune HD will use one of the most powerful chips to go into a portable media player yet: Nvidia's multicore Tegra processor.

Tegra packs two processor cores based on intellectual property from U.K.-based chip designer ARM. One is the main processor--based on the ARM11 core--which runs the operating system. Tegra's defining feature, however, is an additional Nvidia GeForce graphics chip.

"Nvidia brings powerful graphics to the portable media player. This is a unique capability," said Jeff Orr, senior analyst for mobile content at ABI Research.

In total, Tegra integrates eight independent processors, according to Michael Rayfield, general manager of Nvidia's mobile business unit. "We accelerate Flash, we have HD video, we do acceleration of rendering of Web pages on the GPU," Rayfield said Wednesday in a conference call, referring to the graphics processing unit. "The Zune HD will be an amazing showcase of what Tegra is capable of doing."

Its processing prowess notwithstanding, Tegra's design flies in the face of the hot, heat-sink-clad Nvidia graphics processors that power the fastest gaming rigs today. Tegra uses less than 0.5 watts of power, an attribute the chip inherits from its power-stingy ARM parentage. This trickle of power consumption is a tiny fraction of Nvidia's bread-and-butter desktop GeForce processors that are often rated well over 100 watts.

The Zune HD comes with a 3.3-inch, 16:9 OLED (480x272 resolution) screen. And also includes an HD (high-definition) Radio, HD (720p) video out, Wi-Fi, a Web browser (with tap-to-zoom technology), built-in accelerometer, and touchscreen QWERTY keyboard.

Audio codec technology has been developed by PortalPlayer, which Nvidia acquired in 2006.

Zune HD will also include a full-screen Internet browser optimized for multitouch functionality.

CNET Reviews applauded the Zune HD:. "This thing was worth the wait, folks...The Zune finally has the power to make good on the promise of delivering one of the richest music experiences on a portable device."

The Zune HD is the first of many Tegra-based devices to come. "There's about 50 devices in design right now with Tegra," Rayfield said. They range from media players to smartphones to smartbooks to Web pads. Smartphones based on the Tegra are due toward the end of the year.

"The next generation should be better. Current Tegra chips use the ARM11MP processor, next gen will use the faster Cortex-A9. Other IP in the chip is Nvidia's," said Tom R. Halfhill a senior analyst for Microprocessor Report.

Microsoft has confirmed that the Nvidia "Tegra" chip is inside the upcoming Zune HD, a big win for Nvidia.

This was reported earlier at Engadget and follows reports earlier this week.

"There's been a lot of chatter about us possibly putting the Nvidia Tegra chip in the Zune HD," Matt Akers, software development engineer in test at Microsoft, said in a June 19 podcast. "Well, we're going to go ahead and confirm that. Yes, the Zune HD does have the Tegra chip in it."

He added: "So much better battery life, graphics acceleration. This thing's like a mini laptop in your hand."

Tegra is the first processor Nvidia has built for power-frugal handheld devices, a major departure from the large, power-hungry graphics processors that it sells to the gaming rig and workstation markets.

The system-on-a-chip (SOC) uses less than 0.5 watts of power, an attribute the main Tegra processor inherits from its power-stingy ARM parentage. (And a tiny fraction of the 50-watt-plus ratings of the chipmaker's desktop graphics silicon.) The defining feature of the Tegra SOC, however, is the Nvidia GeForce graphics chip.

Nvidia Chief Executive Jen-Hsun Huang said at the company's analyst day on Tuesday that the Tegra processor is expected to account for half of Nvidia's business in a few years.

The rumors about Microsoft and Tegra go back to November. The first round of rumors put Nvidia's Tegra in a Microsoft phone (which some analysts still believe is a possibility).

To date, Tegra has 42 design wins, ranging from media players to smartphones to Netbooks, according to Michael Rayfield, general manager of Nvidia's mobile business unit, who spoke during Analyst Day. Out of those 42, about 18 are smartphones, he said. "You'll start to see those show up toward the end of this year."

The Zune HD--due later this year--comes with a 3.3-inch, 16:9 OLED (480x272 resolution) screen. And also includes an HD (high-definition) radio, HD (720p) video out, Wi-Fi, a Web browser (with tap-to-zoom technology), built-in accelerometer, and a touch-screen QWERTY keyboard.

The rumors appear to be true: Microsoft's Zune HD media player will use Nvidia's Tegra, a processor that will play a pivotal role in the chip supplier's future.

PC Perspective reported Tuesday that the Zune chip had been confirmed by Nvidia "staff" at Computex, earlier this month.

Nvidia Chief Executive Jen-Hsun Huang said at the company's analyst day on Tuesday that the Tegra processor is expected to account for half of Nvidia's business in a few years. If this prediction comes true, Nvidia will bear little resemblance to the company it is today: a maker of large, power-hungry chips for gamers and professionals.

Tegra is the polar opposite of the hot, heat-sink-clad graphics processors that power the fastest gaming rigs today. Tegra uses less than 0.5 watts of power (compared, for example, with the Nvidia GeForce GTX 295, which is rated at 289 watts), an attribute the chip inherits from its power-stingy ARM parentage.

Tegra packs two ARM chips. One is the main application processor--based on the ARM11 core--which runs the operating system. Tegra's defining feature, however, is the Nvidia GeForce graphics chip: this is what likely caught Microsoft's eye. In total, Tegra integrates eight independent processors, according to Michael Rayfield, general manager of Nvidia's mobile business unit, who spoke during Nvidia's Analyst Day.

Audio codec technology has been developed by PortalPlayer, which Nvidia acquired in 2006, Rayfield said.

To date, Tegra has 42 design wins, according to Rayfield. "They range from media players to smartphones to smartbooks to Web pads," he said. Out of those 42, about 18 are smartphones. "You'll start to see those show up toward the end of this year," he said.

The smartphones are "household names, household carriers. Names you'll recognize," he said, possibly alluding to Microsoft, among other major brands. A total of 27 manufacturers are working on devices, he said.

Not everybody is impressed, however. "It's surprised me that it's taking as long as it is to get to tier-one (telecommunications carriers)," said Doug Freedman of Broadpoint AmTech. "Tegra has been available for over a year."

The Zune HD--due later this year--comes with a 3.3-inch, 16:9 OLED (480x272 resolution) screen. And also includes an HD (high-definition) Radio, HD (720p) video out, Wi-Fi, a Web browser (with tap-to-zoom technology), built-in accelerometer, and touchscreen QWERTY keyboard.
