As Tom's Hardware is reporting (via Nvidia's official press release), the Zune HD, which is using Nvidia's much-hyped Tegra chipset, has a whopping eight processors to achieve that super-smooth OS:

Specifically, the Tegra provides the Zune HD with eight independent processors, each designed for a specific class of tasks - among them are an HD video processor, an audio processor, a graphics processor, and two ARM cores. Furthermore, the processors can work together or independently to minimize power consumption.

The press release goes on to say that Nvidia has no fewer than "50 active Tegra processor-based design projects currently in the works today," which is a heck of a lot, if you ask us.

And since we believe WM7 devices are going to need Tegra (or Snapdragon) to run as a requirement, you can begin to understand just how massive an overhaul in raw-processing ability Microsoft's new mobile OS will be bringing in 2010.
