The core silicon in the Zune HD is an Nvidia Tegra processor (see photo) based on the power-frugal ARM chip design. The system-on-chip uses less than 0.5 watts of power. Tegra's defining feature is the integrated Nvidia GeForce graphics chip, which gives the Zune its graphics processing oomph.
The Zune HD also uses a SiPORT HD Radio chip and a 32GB flash memory chip from Hynix, according to iFixit.
Probably the most conspicuous feature of the Microsoft media player is a 3.3 inch OLED display capacitive touch screen. OLED screens draw significantly less power than a traditional LCD. "This isn't the first product with an OLED, but it's certainly cutting-edge technology, and something we haven't seen in any Apple devices yet," iFixit said.
The Zune also offers HD (720p) video out, Wi-Fi, a Web browser (with tap-to-zoom technology), built-in accelerometer, and a touch-screen QWERTY keyboard.
Microsoft claims the Zune's battery provides 8.5 hours video playback.
