Nvidia has released the new Nvidia Tegra 4i processor for smart phones. If you are wondering if this is the next version of the Tegra 4 processor, you are both correct and incorrect in a way. The processor is the next version because it is announced after the Tegra 4, but it is not the next version because it is a less powerful processor when compared to the Tegra 4.
Confused? Well, Nvidia wanted to bring the power of the Tegra 4 processor in a less expensive package that manufactures and designers could use to bring the quad core performance of the Tegra 4 to the mid range smart phones. You can say that Nvidia has done a good job in that. This is because the Tegra 4i is definitely more powerful than the Tegra 3, but not as powerful as the Tegra 4.
The Tegra 4i has 60 graphics core built into it, while the Tegra 3 comes with only 12 graphics core. So this means that even though graphics will look awesome on the Tegra 4i, it would not be as awesome as on the Nvidia Tegra 4. Also, the Tegra 4 has the capability to handle a display with a resolution of 3200 x 1200 pixels. But the Tegra 4i can only handle displays with a maximum resolution of 1920 x 1200 pixels. But this is still an awesome resolution to have on a 5 inch display.
And if you want to try out designing your own smart phone using the new Nvidia Tegra 4i, Nvidia has released a reference design called the Phoenix. This is a reference design for a 5 inch 1080p display. And this reference design is for an Nvidia Tegra 4i powered Android smart phone. And to make things more interesting, the Tegra 4i comes with a built in 4G LTE chip.
