Tegra 4 and Tegra 4i , despite the similarity of names, these processors with a high degree of integration are very different from each other. In particular, if Tegra 4 is based on ARM Cortex-A15 architecture, then Tegra 4i is the previous generation processor (ARM Cortex-A9) with integrated modem i500 LTE. Accordingly, these differences determine the purpose of processors: if Tegra 4i focuses mainly on smartphones, Tegra 4 is for tablets and devices with a physical keyboard, set-top boxes, and car multimedia systems.
Before the end of the second quarter, some NVIDIA partners will present their products based on Tegra 4. The company accelerated the announcement of Tegra 4i at the expense of preparing for the mass production of devices based on Tegra 4. Phones based on Tegra 4i should be ready by early next year, and the production of devices based on Tegra 4 will be deployed only in the third quarter this year.
In general, NVIDIA management believes that Tegra 4 processors is a kind of insurance from the drop in demand for personal computers. A good low-cost tablet PC is better, as recognized by Jensen Huang. As a software platform for the majority of mobile devices powered by NVIDIA Tegra processor Jensen Huang sees Android.
