Zune HD Specs

Submitted by on 2 February, 2014 – 4:32 am

Excitement for the Zune HD appears to be building in the blogosphere. While nobody expects it to “kill” the mighty iPod Touch, it appears from early looks like Microsoft might have eventually released a product that would at least challenge it. Latterly , Microsoft released the official specs for the Zune HD, but left out some details. In fact, this is the 1st product of many to come to market using Nvidia’s delayed Tegra chip. You can view the full technical specs at the base of the Zune HD page on Microsoft’s store, though the company quickly released a PDF of tech specs that gives a few of corrections.

 

First, the battery life on the store page is wrong.  It should be up to 33 hours of music and 8.5 hours of video.  Second, the charge time is three hours when wired into a Computer , 2 hours when plugged in with the AC adapter.

 

Some of the audio bitrates have been corrected, too. The official spec sheets leaves out some interesting bits, though.  To start, it’s clear the Zune HD has an accelerometer in it. We’ve seen the device uncover when it is slanted sideways to display photographs or web pages in widescreen mode. That’s not on the spec sheet, but it obviously may be of use if we start to see Zune HD apps in the future. More engaging is the Tegra chip that powers the device, as this is the 1st Tegra-powered device to come to market.

Tegra is available in many different flavours, and we have learned the Zune HD uses the Tegra APX 2600 variant. When Nvidia talks about Tegra APX 2600, they mention it having “eight processors” integrated into a system-on-chip ( SoC ). These are the HD Video Decoder, HD Video Encoder, 2D Engine, Imaging, GPU ( 3D graphics ), Audio, and 2 ARM cores. The APX 2600 uses the ARM11 MPCore chip, which can contain anywhere from 1 to 4 cores ; Nvidia’s configuration is 2. These CPU cores are basically like the single ARM11 core in the iPod Touch and first two generations of iPhone, though the iPhone 3GS has a stronger ARM Cortex A8 core.  The iPhone’s single ARM11 core runs at 412MHz, the iPhone 3GS runs the stronger ARM Coretex A8 at 600MHz. The 2 ARM11 cores in the Tegra APX 2600 run up to 600MHz, but we don’t know if that’s the maximum authorized in the configuration utilized in the Zune HD.

Naturally, the Tegra chip has multiple clock domains and assertive power management to manage clock speeds. Knowing this, we all know just about all vital hardware data about the Zune HD. We don’t know how much RAM it is configured with, as an example. Real 2D and 3D performance have yet to be independently measured, and battery life specs are infrequently a match for reality. We’ll have more about the Zune HD’s hardware, and naturally an appraisal of the device, in the approaching weeks.
