Tegra 4's Power Struggle

Here is a very interesting write up from Anandtech that is a very good read for anyone that is into the SoC wars.

It outlines some details about the Tegra 4's design and architecture as well as some of the issues Nvidia is running into in regards to high power consumption.

The reference devices have been putting out some impressive benchmarks indeed but I think it is impossible for Nvidia to put out devices running at a full 1.9 Ghz. My guess was that devices running Tegra 4 would be set to 1.5 Ghz but after reading this, it seems the situation is much more dire than I thought and I am starting to lower my expectations to perhaps phones running Tegra 4 at 1.2 - 1.4 Ghz.

What do you guys think?
